    Opis:
    The communities of benthic macroinvertebrates, living in the estuary of Oued Souss (Agadir Bay, Morocco), were studied in parallel with the changes that this ecosystem had underwent after the stopping of pollution, caused by untreated wastewater discharge which occurred in November 2002. Three campaigns were undertaken during the summer season. Two of them were carried out while the estuary was receiving wastewater discharge in 2001 and 2002. The 2003 campaign was carried out after the cessation of the pollution. The intertidal macrobenthic fauna shows a similar faunal composition for both seasons during the period when the ecosystem was receiving wastewater discharge. During this period, Hydrobia ulvae was the dominant species, followed by Hediste diversicolor and Scrobicularia plana in decreasing order. In 2003, the number of individuals harvested was significantly larger compared to the period when the ecosystem received wastewater. For the dominance of species, H. diversicolor was dominanted, followed by H. ulvae, Cerastoderma edule, and S. plana in decreasing order. However, in both periods: before and after the end of wastewater discharge, the phylum of mollusks is dominant, followed by that of Annelids and Crustaceans. The study of the coenotic affinity between settlements of different radials allowed us to separate 2–3 groups of radials in 2001 and 2002, respectively, and 3 groups after stopping discharges in the estuary. The specific richness was greater in the year following the end of discharges (22 species in 2003 instead of 14 found during the pollution period: 2001–2002). The longitudinal distribution of the species living in this site in 2001 and 2002 became wider in 2003 and average biomass, determined by the study of the ash-free dry weight, became clearly greater (20.46 g/m2 in 2003; and 15.54 g/ m2 or 15.84 g/ m2 in 2001 or 2002 respectively). This investigation allowed us to acquire a qualitative (species list, species richness) and quantitative (abundance, biomass, species density) database of intertidal benthic macrofauna of the Oued Souss estuary. It represents a reference state. It responds to the requests for information about the quality of the environment immediately after the cessation of wastewater discharge and could serve as a basis for conducting impact studies later.

    Opis:
    This study focused on bird species richness and diversity in Borgu sector, Kainji Lake National Park, Nigeria. The study was undertaken to derive information on the species of birds utilizing the study area, and to determine the relative abundance and diversity of birds in the study area. The Line transect methods was used for the study. The result revealed that the present number and kinds of birds species in all the ranges sampled is very low, with Range 4 having the highest bird’s species richness of (22.29%). A total of 3255 birds were inventoried in all the ranges. These belonged to 44 species from 28 families. Family Ardeidae contain the highest number of 593 birds, followed by the family Sturnidae and Numididae - having 392 and 351 birds, respectively. The findings indicate that birds’ abundance is very low with many bird species displaying 0% relative abundance. The low abundance and diversity of birds indicates that Kainji Lake National Park birds in relation to habitat characteristics is very poor. Furthermore, the result from the test prediction Output shows that the estimators predict that (after 5 samples) there will be 41 birds’ family species in the habitat in future, since they (ACE, ICE, Chao2, Jack2) level off at 41. The result indicate that only the same birds species, instead of new birds species are presently seen in Kainji Lake National Park, which are poorly represented among 28 families sampled. It is, therefore, recommended that environmental education campaign on birds’ conservation and protection should be carried out in the communities around the park so as to persuade residents to stop killing birds.

    Opis:
    Birds are found in a variety of habitats, performing various functions. They are highly sensitive to even minor perturbation in ecosystems. Documentation of avian assemblages in different ecosystems is, therefore, becoming increasingly important from environmental monitoring perspective. In absence of comprehensive account of birds of Bibhutibhushan Wildlife Sanctuary, West Bengal, India, we made an attempt to document the birds thriving in this protected area. A total of 102 species of birds belonging to 13 orders and 46 families were recorded during the study period (June 2013 – May 2016). Maximum number of species belong to the order Passeriformes (49 species) and minimum under order Anseriformes (1 species). Among the total bird species, 83 species (81.37%) were resident, 15 species (14.71%) were winter visitor, three species (2.94%) were summer visitor and one species (0.98%) was passage migrant. We noted 38 species of birds (including 36 residents and two summer visitors) to breed within the sanctuary. Analysis of feeding guild data revealed that 46.08% were insectivore, 22.55% were carnivore, 15.69% were omnivore, 6.86% were granivore, 5.88% were frugivore, 1.96% were nectarivore and 0.98% were herbivore. Grey-headed Fish Eagle (Icthyophaga ichthyaetus) and Red-breasted Parakeet (Psittacula alexandri) are two Near Threatened (NT) species designated by IUCN. Present study is the first scientific documentation of avian assemblage of this protected area and will serve as a baseline data for future avifaunal research, as well as, will be useful in the preparation of Peoples’ Biodiversity Register (PBR) of this area.

    Opis:
    Avifauna are important for the ecosystem as they play various roles as scavengers, pollinators, seed dispersal agents and predators of insect pest and an important indicator to evaluate different habitats both qualitatively and quantitatively. A study was conducted during February 2012 to February 2015 in Chinsurah, the district town of Hooghly, West Bengal, India. This study was done in ix different habitats present in the core region of the town. These are agricultural land, river bank, small woody area, small water body, grassland and human habitat. A total of 67 avian species were recorded during this study. These species show preferences to various habitats, where some are specialist to one of the habitats and some are generalist to different habitats. Abundance of birds in different habitats is different, most probably due to the variation in amounts of resources in these habitats. Due to loss of natural habitats habitat specialists are gradually replaced by habitat generalists.

    Opis:
    The marine species richness (MSR) recorded in 159 sandy beach surveys was analysed in relation to beach width (W). MSR is the number of macrobenthic species collected in a standard intertidal transect survey, excluding insects. Beach width (W) was estimated by dividing the spring tide range [m] by the beach face slope, to give a value in [m]. The relationship between MSR and W was best described by a semilog (exponential) model, which was highly significant: MSR = −5.2+ 10.8 logW. The fit of a power model (MSR = cWz) was also significant. The steep slope of the curve for a power model (z = 0.49) suggests that beaches function as isolated rather than contiguous habitats and that the nature of the habitat becomes more benign as beaches widen. There are some latitudinal effects, with tropical beaches displaying a higher species-area relationship for any beach width than other regions.

    Opis:
    Floristic research on segetal communities was carried out in 2000 on arable fields in the Skierbieszów Landscape Park and its protected zone. Three communities of segetal weeds in cereal crops, and two communities of segetal weeds in root crops were separated in the arable fields of the Skierbieszów Landscape Park. The community Vicietum tetraspermae typicum commonly occurred in cereal crops on brown soils developed from loess soils. The community Echinochloo-Setarietum, which belongs to root crops, was noted in the same habitat. The greatest richness of species was found in Consolido-Brometum and Lamio Veronicetum politae, with the average of 25 species in one record. Both communities were abundant in rare segetal species which are considered to be endangered in our country: Adonis aestivalis, Euphorbia exigua, Lathyrus tuberosus, Muscari comosum, Thlaspi perfoliatum, Veronica polita, Agrostemma githago.
    Badania florystyczne nad zbiorowiskami segetalnymi przeprowadzono w roku 2000 na polach uprawnych Skierbieszowskiego Parku Krajobrazowego. Na polach uprawnych Skierbieszowskiego Parku Krajobrazowego wyodrębniono 3 zespoły chwastów segetalnych w zbożach i 2 zespoły upraw okopowych. Na glebach brunatnych wytworzonych z lessów w zbożach występował powszechnie zespół Vicietum tetraspermae typicum. W tych samych warunkach siedliskowych wyróżniono w uprawach okopowych zespół Echinochloo-Setarietum. Największym bogactwem gatunkowym charakteryzowały się Consolido-Brometum oraz Lamio-Veronicetum politae, liczące średnio po około 25 gatunków w jednym zdjęciu. Fitocenozy te zajmowały niewielkie powierzchnie gleb rędzinowych badanego obszaru. Obydwa zespoły obfitowały w rzadkie gatunki segetalne, uważane za zagrożone w naszym kraju takie jak: Adonis aestivalis, Euphorbia exigua, Lathyrus tuberosus, Muscari comosum, Thlaspi perfoliatum, Veronica polita, Agrostemma githago.

    Opis:
    The paper reports a study of cyanobacterial diversity in a cold-water limestone limnocrene in Central Poland. Samples were collected from 1998 to 2000 and in June 2012. The morphology, population characteristics and species composition of the cyanobacteria assemblages were investigated, and the frequency of taxa was recorded. The large number of taxa identified (30) reflects the microhabitat heterogeneity of this spring. Some species considered epiphytes grew on limestone rocks. The occurrence of the majority of the most frequent taxa was related to the physicochemical characteristics of the spring, but none of them can be considered obligatory crenobionts characteristic of limestone springs. The studied spring is a unique ecosystem with an interesting cyanobacteria microflora whose occurrence is attributable to the spring’s water chemistry, low temperature and variety of microhabitats.

    Opis:
    Distribution of Turkish Quercus L. has a crucial value since Turkey is a transition place between Europe and Asia and located at the meeting point of three phytogeographical regions. To compare the diversity of species and to find the distribution patterns of oaks, species richness of the most current distributions were studied. Relationships of phytogeographical regions and presence of the Anatolian Diagonal relevant to oak distributions were also investigated. Analyses were performed on Davis'grid square system. The highest richness of Quercus species were found at north-western Turkey which were located in the meeting place of Asia and Europe. The lowest richness scores were found at eastern and south-eastern Anatolia. Moreover, latitude, longitude and altitude histograms showed a correlation with species richness. However, the presence of Anatolian Diagonal is partially supported.

    Opis:
    The composition and distribution of ground beetles species in the different urban green areas of the Lublin city, Eastern Poland was studied. Carabids were collected since the end of April till the late July 2011 using pitfall traps. In total 67 carabid species were found during of the study period. The number of species varies from 54 in valley of Bystrzyca to 5 on the lawns along street. The highest species richness (5.94) had the studied floodplain of river Bystrzyca in comparison with other green territories. All studied green areas were distinguished by considerable individuality. Our results support the thesis that despite of the sizeable areas of the lawns and flowerbeds, their role in the diversity maintenance and preservation is minimal.
    W pracy omówiono wyniki badań dotyczących składu gatunkowego zgrupowania biegaczowatych na różnych obszarach zieleni miejskiej w Lublinie (Polska). Badania prowadzone były od końca kwietnia do końca lipca 2011 roku; odłowy biegaczowatych prowadzono za pomocą pułapek naziemnych. W czasie przeprowadzonych badań odłowiono łącznie 67 gatunków biegaczowatych. Liczba gatunków stwierdzonych podczas badań kolejnych obszarów wahała się od 54 do 5. Największą wartością wskaźnika bogactwa gatunkowego Margalefa (5.94) charakteryzował się teras zalewowy rzeki Bystrzycy w porównaniu do innych obszarów zieleni miejskiej. Na podstawie składu gatunkowego poszczególnych stanowisk można stwierdzić znaczne różnice między nimi. Wyniki wskazują również, że pomimo znaczących obszarów trawników na terenie miasta Lublin ich rola w utrzymaniu i ochronie różnorodności biegaczowatych jest minimalna.

    The aim of the study was to conduct an environmental evaluation of 6 selected sections of the improved Mietiułka River, which included an inventory and analysis of the vascular flora associated directly with this watercourse. The results of the study have shown that the flora of the study area is diverse in taxonomic, syntaxonomic and ecological terms, and that it comprises both typical aquatic plants and species characteristic of the habitats surrounding the river. In the flora found in the study sectors, a total of 114 vascular plant species was identified, which come from 42 botanical families, 15 syntaxonomic classes and belong to different ecological groups. Hemicryptophytes, spontaneophytes, species neutral to continentality as well as species included in the phytochorion with boreal elements: Euro-Siberian subelement, were clearly predominant in the species composition of the flora of all the study sectors. The macrophytes commonly found in Poland had the largest proportion. One species with a small number of stands in the country – water dropwort (Oenanthe fistulosa) – as well as two species threatened with extinction, Sagittaria sagittifolia and Hypochoeris glabra, were recorded.

    Opis:
    The article focuses on changes in terrestrial vertebrate fauna of Niebieskie Źródła (Blue Springs) Nature Reserve that occurred between two censuses carried out in the area. The first census was carried out in the period of 1968-1970, and the second census in the period of 1998-1999. In 1998-1999 the occurrence of four species of amphibians, 41 of birds and 15 of mammals was recorded. In comparison with investigations from 1968-1970 two species of amphibians, two species of mammals, and nine species of birds were found to have disappeared from the reserve. In the census carried out in 1998 and 1999 we recorded 22 new species of vertebrates: one new species of amphibian, five species of mammals, and 16 species of birds. The recent observations showed a decline in the abundance of amphibian species in the reserve, especially in the closest vicinity to the urban development around the city of Tomaszów Mazowiecki. The quantitative data on birds showed an increase in the numbers and abundance, which was mainly pronounced in the group of forest species, especially cavity and shrub nesters. We suggest that these changes are directly related to the succession of forest vegetation and its developing vertical structure, as well as to an increase in the forestation of the reserve area.

    Opis:
    Testate amoebae in Vietnam are still poorly investigated. We studied species composition of testate amoebae in 47 waterbodies of South Vietnam provinces including natural lakes, reservoirs, wetlands, rivers, and irrigation channels. A total of 109 species and subspecies belonging to 16 genera, 9 families were identified from 191 samples. Thirty-five species and subspecies were observed in Vietnam for the first time. New species Difflugia vietnamica sp. nov. is described. The most species-rich genera are Difflugia (46 taxa), Arcella (25) and Centropyxis (14). Centropyxis aculeata was the most common species (observed in 68.1% samples). Centropyxis aerophila sphagniсola, Arcella  discoides, Difflugia schurmanni and Lesquereusia modesta were characterised by a frequency of occurrence >20%. Other species were rarer. The species accumulation curve based on the entire dataset of this work was unsaturated and well fitted by equation S =19.46N0.33. Species richness per sample in natural lakes and wetlands were significantly higher than that of rivers (p < 0.001). The result of the Spearman rank test shows weak or statistically insignificant relationships between species richness and water temperature, pH, dissolved oxygen, and electrical conductivity.

    Opis:
    We studied the relationship between tree-species diversity and the above-ground biomass on an example of two natural Polish forest with different altitiudinal range, plant species pool, vegetation and climatic conditions. The study sought to determine whether: (1) above-ground biomass in natural forests correlates with tree-species diversity irrespective of the kind of forest (montane or lowland), and (2) the relationship in question is negative, (3) the above-ground biomass is greater in montane forests than in lowland ones. Natural forests present in 1º Polish Gorce Mountains (montane forest) alongside comparable data for the 2º world-renowned lowland forest that is present in the Białowieża National Park. Data were collected within 558 sample plots (á 200-square-metre). The diameter at breast height of all trees with girths of or exceeding 12 cm was measured. To compute above-ground biomass we calculated dry masses for each tree on the basis of values for dbh and height, next we summed these values for all species present within each plot. The number of tree species on a plot ranged from only one (mainly in spruce stands) to six (in mixed deciduous lowland forest stands). The above-ground accumulated biomass ranged from 6 to 1155 (average 251±13) t ha–1 within the lowland forest, and from 2 to 849 (average 242±8) t ha–1 within the montane forest. We concluded that there was a humped-back shaped relationship between tree-species diversity and above-ground biomass in both lowland and montane natural forests.

    Opis:
    The study was carried out from the beginning of June to the end of July 2005 in the Krasiborska Kępa reserve (UTM VV56; 53.848°N, 14.370°E). Three research plots were established, representing various types of use of reedy areas: an unused reedy area, a reedy area mown in summer, and an area mown in winter. Beetles were collected in Barber traps with ethylene glycol as a preservative liquid. Seven traps were set up in each examined habitat. In total 1,145 specimens belonging to 35 species were caught. The relatively small area presented three different carabid assemblages, differing in species richness, abundance, dominance structure and ecological preferences. The highest species richness and abundance, as well as the largest representation of endangered stenobiontic hygrophilous bog species (Trechus rivularis, Carabus clathratus, Carabus menetriesi, Bembidion fumigatum, Blethisa multipunctata, and Oodes helopioides), were observed in the  periodically flooded fen which was mowed in the winter.
    W wyniku badań przeprowadzonych w czerwcu i lipcu 2005 roku, na trzech stanowiskach o charakterze torfowiskowym w północno-wschodniej części rezerwatu Karsiborska Kępa zebrano 1145 osobników należących do 35 gatunków. Na względnie małym terenie występują trzy różnych zgrupowania biegaczowatych. Różnice polegają na bogactwie gatunkowym, liczebności, strukturze dominacji i preferencjach ekologicznych. Największe bogactwo gatunkowe i liczebność, oraz największa reprezentacja przyrodnicza cennych stenobiontycznych higrofilnych torfowiskowych gatunków (Trechus rivularis, Carabus clathratus, Carabus menetriesi, Bembidion fumigatum, Blethisa multipunctata, Oodes helopioides) znajdowała się na stanowisku 3 – okresowo zalewanym torfowisku niskim, koszonym w okresie zimowym.

    Opis:
    Attempts to study biodiversity hotspots on a regional scale should combine compositional and functionalist criteria. The detection of hotspots in this study uses one ecologically similar group of high conservation value species as hotspot indicators, as well as focal habitat indicators, to detect the distribution of suitable environmental conditions. The method is assessed with reference to thermophilous forests in Poland – key habitats for many rare and relict species. Twenty-six high conservation priority species were used as hotspot indicators, and ten plant taxa characteristic of the Quercetalia pubescenti-petraeae phytosociological order were used as focal habitat indicators. Species distribution data was based on a 10 × 10 km grid. The number of species per grid square was interpolated by the ordinary kriging geostatistical method. Our analysis largely determined the distribution of areas with concentration of thermophilous forest flora, but also regional disjunctions and geographical barriers. Indicator species richness can be interpreted as a reflection of the actual state of habitat conditions. It can also be used to determine the location of potential species refugia and possible past and future migration routes.

    Opis:
    The objective of this study was to examine the vegetation cover and describe the floristic diversity of selected plant communities of extensive and abandoned grasslands within the Forest of Parczew PLB060006 – a Natura 2000 protected area. Floristic surveys were conducted in the meadows in years 2001 and 2013 under the conditions of natural succession of the communities Poa pratensis-Festuca rubra. The area is situated in the northern part of the Lublin Voivodeship, in the physiographic mesoregion the Łęczna-Włodawa Lakeland. Those communities were characterized by average species richness and floristic diversity index values. The cover index decreased considerably in the case of 8 species, and increased for 12 species. A large increase in the cover index of Holcus lanatus, Deschampsia caespitosa, Galium mollugo, Anthriscus sylvestris and Polemonium caeruleae is particularly noteworthy. In 2001, 39 species of plants were recorded in all relevés, compared to 41 species recorded in 2013. Over 12 years, 11 species disappeared, but 13 new ones emerged. For the time being, the average species richness N increased from 12 to 16 per relevé. The biodiversity index H' increased from 2.8 to 3.6.
    W artykule przedstawiono wyniki badań fitosocjologicznych na obiekcie Ochoża prowadzonych w 2001 i 2013 r. Z analizy danych wynika, że gatunkami występującymi na wszystkich badanych stanowiskach były głównie Poa pratensis i Festuca rubra oraz Urtica dioica. W 2013 r. na wszystkich badanych stanowiskach, oprócz gatunków omówionych wyżej, występowały także Rumex acetosa, Galium mollugo, Veronica chamaedrys i Cardaminopsis arenosa. Na podstawie analizy wyników badań stwierdzono, że w przypadku 15 gatunków klasa stałości w 2013 r. w porównaniu ze stanem z 2001 r. zwiększyła się, a w przypadku pozostałych się nie zmieniła. Odnotowano także zmiany współczynnika pokrycia. Uległ on znacznemu zmniejszeniu w przypadku 8 gatunków, a zwiększył się w przypadku 12 gatunków. Na szczególną uwagę zasługuje duże zwiększenie wartości współczynnika pokrycia Holcus lanatus, Deschampsia caespitosa, Galium mollugo, Anthriscus sylvestris oraz Polemonium caeruleae (w Polsce gatunek objęty ochroną prawną). W 2001 r. we wszystkich stanowiskach odnotowano 39 gatunków roślin, zaś w 2013 r. odnotowano 41 gatunków. Przez 12 lat zanikło 11 gatunków, ale pojawiło się 13 nowych. Przez 12 lat średnia liczba gatunków N zwiększyła się z 12 do 16. Zwiększył się także wskaźnik bioróżnorodności H’ z 2,8 do 3,6.

    Opis:
    Linseed, one of the oldest cultivated crops, is again gaining in importance, mainly due to its nutritional benefi ts and biomedical applications. Th erefore, it is expected that herbivores will also exist in greater abundance. Among them the fl ea beetle, Aphthona euphorbiae Schrank and Longitarsus parvulus Paykull are considered to be serious pests of fl ax grown for fi bre and seeds in Europe. Th e aim of this study was to determine fl ax fl ea beetles’ abundance, species richness and seasonal dynamics on linseed grown at diff erent densities. It was expected that linseed seeding density can signifi cantly aff ect fl ea beetle populations. Th e experiment was carried out in Lower Silesia, Poland, from 2011 to 2013. A genetically modifi ed type of linseed overproducing fl avonoids was used. Flea beetles and the damages they caused were determined on plants and also a sweep net was used for the collection of adult beetles. During the three years of the study 15 species of fl ea beetles were identifi ed from oil fl ax plants, with A. euphorbiae and L. parvulus being dominant. In terms of the total catch, the tendency was for beetle numbers to decrease with increasing plant density. Flax fl ea beetles feeding on linseed plants, irrespective of plant density, had two peaks of abundance. Th e fi rst peak was lower and occurred in June, when plants were at the blooming stage. Th is peak was caused by overwintering adults who colonized crops in spring. Th e second, higher peak of abundance was recorded in the second half of July, when plants were at the ripening stage. Th is peak was formed by adults of the new generation. Each year, at the higher population peak of abundance, the fl ea beetles were most numerous on plants grown at the lowest density. Th ere was one period, lasting either from mid-May to the fi rst few days of June, or from the beginning of June to mid-June, during which the number of holes and damage on plants of each treatment were highest. During the three years of the study there were several cases of signifi cantly higher numbers of fl ea beetle feeding symptoms on plants grown at the lowest density as compared to the medium and highest densities.

    Opis:
    We examined the diversity and composition of fungi from the interior of saxicolous (rock inhabiting) lichens covering basaltic and chalk rocks at the Alma–Har-BenZimra area of Upper Galilee, Israel. We also compared the composition of lichen-associated and soil microfungal communities inhabiting the two contrasting soil types in the area to trace possible sources of formation of endolichenic fungal assemblages. In the course of the study, 39 fungal species were isolated from the interior of 13 lichen species. Species richness of the endolichenic fungal communities was associated, to some extent, with the growth form of lichens, being higher in those lichens with thick, warted, and wrinkled thalli. Species composition of the communities was characterized by the dominance of melanin-containing microfungi with large, multicellular, and thick-walled spores that significantly increased in abundance in the summer. Dominant species were also known as endophytes and phylloplane-inhabiting fungi; at the same time, typical soil-borne species were extremely rare components of the isolated endolichenic communities. Some endolichenic melanized microfungi were comprised by coprophilous species prevailing in some lichen thalli; this observation was probably due to a long period of use of the studied area for cattle grazing. Protective morphological features are important for fungi inhabiting the interior of lichen thalli characterized by limited nutrient sources, low-water availability, and restricted aeration. In addition, endolichenic fungi should resist the activity of various extracellular secondary metabolites produced by their host lichen species.

    Opis:
    The diversity of ectomycorrhizal fungi and sporocarps abundance were investigated in 2003-2005 at nine permanent study plots in a 50-year-old pine forest. Diversity of ectomycorrhizal fungi consist of 53 taxa and the majority of them belonged to the genera Cortinarius, Russula, Amanita and Tricholoma. The most frequent species, whose fruit bodies were found in each study plot, were C. cibarius, L. necator L. rufus, P. involutus, R. aeruginea, T. saponaceumand the most abundant species which made the main part of total sporocarp yield were C. cibarius and P. involutus. The lowest species richness of ectomycorrhizal fungi was in study plots with the densest cover of grasses. Maximum of species over the fruiting period was characteristic for October and for September. It was noticed that some species virtually never occurred together at the same plot (e.g. C. cibarius and H. aurantiaca), meanwhile others occurred together quite frequently (e.g. H. aurantiacaand X. badius).

    Opis:
    The study was focused on soil factors influencing species richness and diversity after disturbance of the substrate followed by abandonment. Two types of disturbances in the past were considered: the removal of trees and shrubs with the resulting major destruction of soils, and deep ploughing. As a control meadows not covered by any management schemes for 50 years were studied. The topsoil stripping resulted in decrease of potassium, nitrogen and organic carbon contents, while deep ploughing caused less radical effects. Simultaneously, disturbances of the soil delayed the course of succession, and brought increase in species. The most species-rich are ploughed meadows. No differences in terms of species diversity, domination and evenness between the forms of disturbances were identified. However, there were groups of species indicative for soil disturbances. Analysis of the relationships between vegetation differentiation and the properties of soil suggests that available phosphorus may affect species richness and diversity in mountain meadows.

    Opis:
    A lichenological inventory was conducted in the pine stands in the south-eastern region of Żerków-Czeszewo Landscape Park. The aim of this study was to recognize the lichen species diversity on the bark of Pinus sylvestris by considering tree age and forest habitat type. In total, 26 species of lichenized fungi were found on the bark of P. sylvestris. The biota comprises common and widespread species in Poland. Tree age positively and significantly influenced the species richness on the bark of P. sylvestris. The suitability of the pine tree age for lichens evident as alpha diversity seemed to be independent from the habitat of the trees. The age of phorophytes strongly affected the presence of Hypocenomyce scalaris. Mixed fresh coniferous forests were characterized by higher beta- and gamma diversity compared to fresh coniferous forests. There was no correlation between the number of species per tree (alpha diversity) and diversification of species composition in relation to the distance between pines. The findings indicate that maintenance of a variety of phorophytes and age-diversified tree stands can prevent impoverishment of the lichen biota in the south-eastern part of Żerków-Czeszewo Landscape Park.

    Opis:
    The objective of this study was to estimate the edge effect on the species richness in agriculturally maintained forest-grassland boundaries of coniferous forest and to determine how species respond to a forest edge. We hypothesised that species number, cover of herbs and mosses is higher in the edge, and species penetrates from nearby grasslands into forest interior. The study was conducted in the Southwestern Lithuania. The edge effect on overall herbaceous species composition of coniferous forests was evaluated by Canonical Correspondence Analysis. The species richness of herbs and mosses in the coniferous forest was highest in the forest edge and declined towards interior. The highest decrease in the number of species occurred within 0 to 5 m to the edge. The highest cover of herbs and mosses was in the forest edge and decreased towards the forest interior. CCA biplot showed a good correlation of overall species composition and the distance to the forest edge. Distribution of species along edge to interior gradient depended on the species response to different ecological factors. Ellenberg value of light was higher in the edge. Ellenberg value of nitrogen was higher in the forest interior.

    Opis:
    Plant diaspore dispersal is a fundamental process affecting the development of forest vegetation and its natural regeneration, especially with regard to typical woodland species, which spread slowly and form short-term soil seed banks. Most of these species have poor seed dispersal mechanisms, which is the major cause of their very slow expansion. The following questions were asked: (i) is there a relationship between the age of a woodland and the presence of forest vascular plant species representing different seed dispersal types; (ii) how do the proportions change between species representing different seed dispersal types in relation to the age of woodland; (iii) what factors determine the presence of species representing a given seed dispersal type; (iv) which factors affect the presence and which ones influence the abundance of selected woodland species? A multiple regression models were developed based on data obtained from 144 woodland patches designated for the study. A probit regression analysis was performed for selected species exhibiting various seed dispersal models. Woodland plants of all seed dispersal types show a significant relationship with the age of woodland, starting from the strongest linkage: anemochores, myrmecochores, endozoochores, epizoochores, barochores, autochores. As the woodland ages, the proportion of forest myrmecochores and anemochores grows, whilst the proportion of autochores, epizoochores and endozoochores shrinks. Results obtained indicate that the direct proximity of ancient woodland has a major effect on the occurrence of more poorly dispersing plants in recent woodlands, such as myrmecochores and heavy anemochores.

    Opis:
    Scots pine forest are of the main economic importance to the forest management in lowland Europe. Large areas of spontaneous pine forest, including old−growths, are located on two vast dune belts of the Kampinos National Park (central Poland). These forests grow on oligotrophic sandy soils with deep groundwater level. This makes the area unique to study long−term changes in this type of pine forest communities. The aim of the work was to assess the changes in the species composition and richness of undergrowth of Scots pine forests at the beginning of the XXI century. The study was conducted on 10 permanent and 53 semi−permanent plots located within stands of Peucedano−Pinetum and Querco−Pinetum associations on both dune belts of Kampinos National Park. The fieldworks were performed in 2001 and 2002, and repeated in 2015 and 2018. Based on Ward’s cluster analysis we described five local forms of plant communities. Seven species groups were distinguished and changes in their richness assessed using one sample Wilcoxon test. Each species group included species characteristic and/or differentiating for a given set of syntaxonomical units. The results confirmed the hypothesis of gradual decrease of the total species richness. The median of species richness change was –0.308 species per year and was statistically significant. The changes were bigger within the local forms of the Querco−Pinetum association in comparison to Peucedano−Pinetum. The decrease was connected especially with dry grassland and heathland species (characteristic for syntaxons of Koelerio−Corynephoretea and Nardo−Callunetea classes) as well as with coniferous forest generalist species (characteristic for syntaxons of Vaccinio−Piceetea and Cladonio−Vaccinietalia). The results suggest that the two main processes shaping the species composition at the beginning of XXI century within pine forest located on the dune belts of Kampinos National Park may be identified as (i) fluctuation, and (ii) simplification, manifested by species richness decrease. This is probably connected with forest regeneration after past human use and disturbance.

    Opis:
    W pracy przedstawiono wyniki badań wpływu ograniczonego użytkowania łąki górskiej na jej bogactwo i różnorodność florystyczną oraz wydajność i jakość paszy. W doświadczeniu, założonym w 2002 r. na odłogowanej łące, zastosowano zróżnicowaną intensywność koszenia: raz w roku oraz raz na dwa i raz na trzy lata w dwóch wariantach - z biomasą zebraną i zostawioną. Na podstawie wyników z lat 2005-2007 stwierdzono korzystne zmiany w strukturze i składzie gatunkowym roślinności na obiektach koszonych, co wpłynęło na zwiększenie bogactwa i różnorodności florystycznej oraz wydajności. Większą liczbę gatunków i wskaźnik Shannona-Wienera H' stwierdzono na obiektach koszonych corocznie i raz na dwa lata. Pozostawienie biomasy wpłynęło istotnie na zmniejszenie obydwu wartości. Średnie plony suchej masy (3,7 t·ha-1) były wyższe o ok. 0,5 t·ha-1 od plonów z obiektu kontrolnego. Analiza statystyczna nie wykazała istotności różnic między wysokością plonów z obiektów o zróżnicowanej częstości koszenia w wariantach z zebraną i zostawioną biomasą. Pasza z obiektów koszonych corocznie charakteryzowała się najmniejszą zawartością białka i tłuszczu.
    The study presents results of research in the impact of limited use of mountain meadows, their variety and diversity of species as well as quantity and quality of forage. During the experiment started in 2002 in an uncultivated meadow, varied frequency of mowing was applied: once a year, once in two and three years in two variants - the biomass being removed or left. The experiment results from 2005-2007 show positive impact on the structure and composition of species in the mown objects, which increased variety and diversity of flora as well as productivity. The objects mown once a year and once in two years demonstrated bigger richness of species and higher Shannon H' index. Leaving the biomass substantially decreased the respective values. Average crop of the dry substance (3.7 t ha-1) was about 0.5 t ha-1 higher as compared to the control object. Statistic analysis showed no significance of differences between the crops from objects of varied frequency of mowing and in the variants with removed and left biomass. Forage harvested from the objects mown once a year had the lowest protein and fat content.

    Opis:
    The information about the distribution of caddisflies (Trichoptera) in mid-western Poland being a part of the Wielkopolsko-Kujawska Lowland (WKL) faunistic region is still scarce compared to other regions. To close the knowledge gap, we investigated caddisflies larvae and occasionally imagines in a selected area in mid-western Poland in 2011. The aim was the preliminary estimation of species richness and abundance of protected, rare and endangered species in this part of WKL. For the study 63 sampling sites representing broad spectrum of habitat types were chosen and analysed with various ecological indices. In total, 75 species: 46 as larvae and 51 as imagines were found in the area. Among them, one protected species (Crunoecia irrorata), 5 listed in the Polish Red List (Erotesis baltica, Hydropsyche bulgaromanorum, Ylodes simulans, Limnephulus borealis and L. fuscinervis), and 11 species not reported for WKL yet were found in the area. In the whole material, the most frequent and dominant species was Limnephilus flavicornis. In contrast, 50 species were recorded in less than 5% of sites. The highest species richness was found in rivers and fish ponds with total number of 33 and 32 species, respectively, whereas the lowest one in springs (5 species) and bogs (6 species). The highest species diversity obtained with probability of intraspecificencounter (PIE) Index was found in fish ponds (0.90) and rivers (0.85) as well. In contrast, streams had the lowest PIE value (0.60) in the area. The most valuable habitat types with regard to protected, endangered and rare species were rivers and fish ponds, as well as lakes and streams of lower importance. To conclude, our investigation indicated a high species richness and diversity in the area, which was related to high habitat heterogeneity, thus having significant importance for biodiversity preservation in mid-western Poland. Moreover, fish ponds and rivers were the most valuable habitat types significantly contributing to species richness, diversity and preservation of rare and endangered species in this area.
    Wiedza na temat rozmieszczenia chruścików (Trichoptera) w środkowo-zachodniej Polsce, będącej częścią krainy faunistycznej Niziny Wielkopolsko-Kujawskiej (WKL) jest wciąż uboga w porównaniu do innych regionów. W celu uzupełnienia tej informacyjnej luki w roku 2011 przeprowadzono inwentaryzację wybranego obszaru w tej części kraju. Celem pracy było wstępneokreślenie różnorodności gatunkowej oraz gatunków chronionych, zagrożonych i rzadkich w tej części WKL. Próby pobrano z 63 stanowisk obejmujących szerokie spektrum typów siedliska następnie przeanalizowano przy użyciu różnych wskaźników ekologicznych. Ogółem stwierdzono 75 gatunków chruścików, w tym 46 i 51 odpowiednio w postaci larw i osobników dorosłych. Wśród stwierdzonych gatunków jeden jest chroniony (Crunoecia irrorata), 5 znajduje się na Polskiej Czerwonej Liście (Erotesis baltica, Hydropsyche bulgaromanorum, Ylodes simulans, Limnephulus borealis and L. fuscinervis) a 11 nie było dotychczas podanych z WKL. Z całości materiału gatunkiem o najwyższej dominacji i frekwencji był Limnephilus flavicornis. Natomiast aż 50 gatunków stwierdzono w mniej niż 5% stanowisk. Najwyższą liczbę gatunków zanotowano w rzekach i stawach rybnych, odpowiednio 33 i 32, natomiast najmniejszą w źródłach (5 gatunków) oraz na torfowiskach (6 gatunków). Najwyższą różnorodnością gatunkową mierzoną według wskaźnikaPIE charakteryzowały się również stawy rybne (0.90) i rzeki (0.85), natomiast najniższą wartość PIE (0.60) stwierdzono w strumieniach. Pod względem udziału gatunków chronionych, zagrożonych i rzadkich najbardziej cenne okazały się rzeki oraz stawy rybne, a także w mniejszym stopniu jeziora oraz źródła. Reasumując, badany obszar charakteryzuje się dużym bogactwem oraz różnorodnością gatunkową chruścików mających znaczenie dla ochrony bioróżnorodności w środkowo-zachodniej Polsce. Najbardziej cennymi typami siedlisk dla zachowania bogactwa, różnorodności oraz dla gatunków rzadkich i zagrożonych są rzeki oraz stawy hodowlane.

    Opis:
    Although aquatic beetles are one of the most diverse groups significantly contributing to species diversity in freshwaters, their occurrence and distribution has been studied very poorly in mid-western Poland. Consequently, our knowledge about the current aquatic beetle species richness and habitat preferences is still scarce in large parts of this region. To close this knowledge gap, we investigated a selected area of approximately 500 km2 in the south-western part of the Lubuskie Province, part of the Wielkopolsko-Kujawska Lowland, to obtain the richness of total, protected, endangered and rare species of aquatic beetles, as well as to analyse their diversity and ecological groups in representative habitats. For the study, 70 sampling sites representing ditches (5 localities), streams (4), rivers (13), small water bodies in open landscapes (7) and in forests (6), temporary (8) and permanent (7) fish ponds, lakes (4), fens (1), peat bogs (13) and marshes (2) were investigated from April to September 2011. In total, 115 species, including 10 protected by law or/and listed on the Polish Red List, as well as 11 rare and local in Poland species were found in the study area. Among them special attention should be paid to Macroplea appendiculata – a recently-discovered for the Wielkopolsko-Kujawska Lowland and critically endangered in Poland species as well as Rhantus incognitus – an endangered and rare species in Poland. The most frequent species was Hyphydrus ovatus (34.3% of sites), whereas 29 species, mostly stenotopic specialists, were recorded in only one site. Eurytopes and tyrphophiles were both present in each habitat type. Further, the most diverse habitats were temporary ponds containing 7 groups of stenotopes, whereas in streams only 2 groups were found. On average, the most species rich habitats were permanent ponds (median = 11 species) and bogs (11), but the highest species numbers were found in a temporary pond (44 species) and in a small water body in open landscape (42). The lowest species richness was found in streams (maximum4 species per site). According to an evaluation of habitat types based on protected, threatened and rare species, the most important were permanent and temporary ponds in the forested, water-rich parts of the study area. In agriculturally dominated parts, however, small rivers and occasionally small water bodies were of high importance for rare species.We conclude that the species richness and abundance of protected, endangered and rare species are high in the study area in comparison to other parts of Poland. The most important habitats in terms of high diversity of aquatic beetles are predominantly permanent fish ponds and bogs, whereas permanent and temporary fish ponds play a key role for the high content of rare and protected speciesin the area.
    Chrząszcze wodne są jedną z najbardziej bogatych w gatunki grup znacząco przyczyniających się do różnorodności gatunkowej w wodach słodkich, jednak ich występowanie i rozmieszczeniew Polsce środkowo-zachodniej było badane w bardzo małym zakresie. W konsekwencji nasza obecna wiedza o ich różnorodności gatunkowej oraz preferencjach siedliskowych w tej części kraju jest znikoma. W związku z tym przeprowadzono inwentaryzację wybranego terenu o powierzchni ok. 500 km2 w południowo-zachodniej części województwa lubuskiego, według Katalogu fauny Polski leżącego na Nizinie Wielkopolsko-Kujawskiej. Celem badań było określenie różnorodności gatunkowej oraz udziału gatunków chronionych, zagrożonych i rzadkich, a także analiza grup ekologicznych chrząszczy wodnych w reprezentatywnych biotopach. Próby pobrano z 70 stanowisk reprezentujących: rowy (5 stanowisk), strumienie (4), rzeki (13), oczka wodne w terenie otwartym (7) i śródleśnym(6), stawy rybne z okresowym (8) i permanentnym (7) stanem wody, jeziora (4), torfowiska niskie (1), torfowiska sfagnowe (13) oraz bagna (2) w okresie od kwietnia do września 2011 r. Stwierdzono 115 gatunków, w tym 10 gatunków chronionych lub/i uwzględnionych w Polskiej Czerwonej Liście oraz 11 gatunków rzadkich i lokalnych w Polsce. Na szczególną uwagę zasługują Macroplea appendiculata – gatunek krytycznie zagrożony (CR), chroniony oraz nowy dla Niziny Wielkopolsko-Kujawskiej, oraz Rhantus incognitus – gatunek zagrożony (EN) i rzadko spotykany w kraju. Najwyższa frekwencja cechowała Hyphydrus ovatus (34,3% stanowisk), natomiast 29 gatunków, w większościstenotopów, występowało tylko na jednym stanowisku. Spośród grup ekologicznych, eurytopy i tyrfofile występowały we wszystkich typach siedlisk. Najbardziej różnorodne pod względem typów ekologicznych chrząszczy były stawy okresowe, w których zanotowano 7 grup stenotopów. Najmniej stwierdzono ich w strumieniach (2 grupy). Średnio, największą ilością gatunków charakteryzowały się stawy permanentne (mediana = 11 gatunków) oraz torfowiska (11), natomiast maksymalnienajwięcej gatunków zanotowano w stawach okresowych (44 gatunki) oraz w małych zbiornikach terenów otwartych (42). Najmniej bogate gatunkowo były strumienie (maksymalnie 4 gatunki na stanowisko). Wyniki ewaluacji typów siedlisk pod kątem występowania gatunków chronionych, zagrożonych i rzadkich wykazały, że najbardziej istotne były permanentne i okresowe stawy na obszarach zalesionych i bogatych w wody. Jednak w obrębie dominacji agrocenoz, ważne dla zachowaniatych grup gatunków okazały się małe rzeki oraz częściowo małe zbiorniki.Na podstawie przeprowadzonych badań należy stwierdzić, że obszar środkowo-zachodniej Polski charakteryzuje się dużym bogactwem gatunków chrząszczy wodnych oraz dużym udziałem gatunków chronionych, zagrożonych i rzadkich na tle innych części kraju. Najważniejszymi typami siedlisk w aspekcie różnorodności gatunkowej są głównie stawy permanentne oraz torfowiska. Natomiast stawy okresowe i permanentne odgrywają kluczową rolę dla zachowania gatunków rzadkich na tym obszarze.

    Opis:
    W pracy przedstawiono ocenę bogactwa gatunkowego i różnorodności florystycznej zbiorowisk użytków zielonych i gruntów ornych obszaru Pogórza Złotoryjskiego. W przypadku użytków zielonych największe wskaźniki bogactwa gatunkowego i różnorodności florystycznej uzyskały zbiorowiska w klasie Molinio-Arrhenatheretea, a najmniejsze zbiorowiska z klasy Artemisietea vulgaris. Średnie wartości wskaźników dla tego terenu miały zbiorowiska z klas Agropyretea intermediorepentis i Phragmitetea. Wpływ na bogactwo i różnorodność miały przede wszystkim brak użytkowania i zachodząca z tego powodu sukcesja wtórna. Produkcja polowa na badanym obszarze charakteryzuje się wysoką kulturą rolną, co spowodowało dominację na gruntach ornych zbiorowisk zubożałych i fragmentarycznie wykształconych. Nie było możliwe określenie zespołów, lecz jedynie wydzielenie zbiorowisk z dominującym gatunkiem. Wszystkie cztery zbiorowiska zakwalifikowano do klasy Stellarietea mediae. Brak wielu gatunków przełożył się na stosunkowo niewielkie bogactwo i różnorodność florystyczną fitocenoz chwastów towarzyszących uprawom.
    This paper presents an assessment of species richness and floristic diversity of grassland communities and arable lands in the Złotoryja Foothills area. In grasslands, the communities of Molinio- Arrhenatheretea class had the highest indices of species richness and floristic diversity, whereas those from the class Artemisietea vulgaris showed the lowest indices. The communities of Agropyretea intermedio-repentis and Phragmitetea classes had the medium index values for this area. Abandoned use and resulting secondary succession were the main reason for the decline in species richness and diversity. Field production in the study area is characterised by a high agrarian culture and this brought about the domination of impoverished or partially developed communities. Hence, it was only possible to distinguish communities with one dominating species and the complexes could not be specified. All four communities were qualified to Stellarietea mediae class. The lack of many species resulted in relatively small richness and floristic diversity of weed phytocoenoses accompanying crop plants.

    The mycology of peatlands, with their specific plant communities and numerous rare plant species, has been underexplored and is poorly recognized. The main objectives of this study were to identify the species richness and diversity of macromycetes in raised and transitional bogs of Pomerania and to establish correlations between macroscopic fungi and peatland communities occurring in the area in view of environmental conditions. Investigations spanning a period of ten years were conducted at 134 sites (71 raised and 63 transitional bogs) in eight non-forest peatland communities (Caricetum lasiocarpae, Caricetum limosae, Caricetum rostratae, Eriophoro angustifolii-Sphagnetum recurvi, Rhynchosporetum albae, Erico-Sphagnetum medii, Sphagnetum magellanici, and the Eriophorum vaginatum-Sphagnum fallax community) and two forest communities (Vaccinio uliginosi-Pinetum and Vaccinio uliginosi-Betuletum pubescentis) in which 108 permanent observation plots were established for detailed examinations. A total of 191 macromycete species were recorded in the peatlands. The smallest number of species was recorded in Rhynchosporetum albae (12 species) and Caricetum rostratae (15 species). Phytocoenoses richest in fungi were Vaccinio uliginosi-Pinetum (102 species) and Vaccinio uliginosi-Betuletum pubescentis (121 species). The number of macromycete species recorded in individual peatland communities depends on the community type and is not conditioned by the number of observations and the number and the total area of permanent plots. Five mycosociologico-ecological groups of macroscopic fungi were distinguished based on numerical analyses. Four groups comprise species of fungi associated with a specific phytocoenosis or a group of phytocoenoses. One group consists of fungi with a broader ecological scale. The majority of environmental variables representing the substrate’s chemical properties, humidity and pH show a statistically significant influence on the diversity of macroscopic fungi species in the peatland communities. Cartogram maps of the distribution of 21 species of peatland fungi are included and geographico-ecological features of the species are briefly described.

    Opis:
    The goal of the present research was to find correlations between the topographic attributes of a river valley and local ground-floor vegetation and its habitat requirements expressed by ecological indicator values (EIV), using the geographical information systems (GIS), digital elevation model (DEM), and multivariate statistical analysis. We paid special attention to the river course, which determines the differentiation in slope aspects and the amount of solar radiation reaching the ground surface. The model object was an almost latitudinal, ca. 4-km-long break section of the Sopot river, crossing the escarpment zone of the Central Roztocze Highlands, southeastern Poland. The main material comprised species lists (with estimated abundance) for each ca. 200-m-long section, according to the river valley course, separately for the left and right riverbanks, 40 sections altogether, ca. 15 000 vegetation records, and physical and chemical soil measurements. A 3-meter resolution DEM was derived from a 1:10 000 topographic map. We calculated the correlations between the topographic attributes of the valley, species richness, and the EIVs for all the species recognized in each section of the valley. We found 241 herb plant species in the ground-floor vegetation of the study area. We did not find significant differences between the two riversides (61 ±13 species per one section for the left and 63 ±17 for the right side). Thus, the parallel course of the river valley does not change the species richness on a more “sunny” and more “shiny” riverbank. However, this factor “cooperating” with other topographic attributes of the valley significantly differentiates the shape of species showing various requirements for basic habitat resources: light, moisture, soil trophy, reaction, dispersion, and organic-matter content.

    Opis:
    Grasslands were seen in the past primarily as a source of feed. The important function of grassland, beside the role of feed, consists in their natural value and role in the landscape. The aim of this study was to assess natural and landscape values of the distinguished meadow-pasture communities in Kłodzko. It is located in the south-western part of Poland, within the Sudety chain and is surrounded by mountains that form its natural boundary. The whole area of the county is very diverse in terms of physiogeography and climate what affects its natural and landscape values. The natural value of the seven distinguished plant units: 4 assosciations - Angelico-Cirsietum oleracei, Arrhenatheretum elatioris, Lolio-Cynosuretum, FestucoCynosuretum, 3 communities with dominant species - Poa pratensis-Festuca rubra, community with Agrostis capillarisFestuca rubra, community with Trisetum flavescens, on subject area was determined on the basis of the species richness represented by the total number of species, the Shannon-Wiener species diversity index H' and the presence of endangered and rare species. These phytocenoses are characterized by a large species richness from 34 to 150 species. The values of the H' index are at an average level and ranged from 2.32 to 2.64. Community with Trisetum flavescens is characterized by the highest diversity index value. The biggest species richness is in the Lolio-Cynosuretum. Among species legally protected are noted in Poland: Carlina acaulis and Colchicum autumnale and near threatened (NT) Geranium sylvaticum. Plant species richness, the high proportion of the color of flowering herbs and weeds and Fabaceae plants flowering in different time of the growing season, affect the aesthetic qualities and the landscape values of the meadow-pasture communities analyzed. Their location in the landscape varied with hills and terrain, enhancing the landscapes of the studied Kłodzko county.
    Użytki zielone postrzegane były w przeszłości przede wszystkim jako źródło paszy. Obecnie, zwłaszcza w sytuacji zaniechania lub ograniczania chowu zwierząt, ważną funkcją użytków zielonych, obok roli paszowej, jest ich wartość przyrodnicza i rola w krajobrazie. Celem pracy było określenie wartości przyrodniczej oraz krajobrazowej wyróżnionych zbiorowisk łąkowo-pastwiskowych w powiecie kłodzkim, który znajduje się w południowo-zachodniej części Polski, w obrębie łańcucha Sudetów. Otoczony jest górami stanowiącymi jego naturalną granicę. Cały obszar powiatu jest silnie zróżnicowany pod względem fizjogeograficznym i klimatycznym, co wpływa na jego walory przyrodnicze i krajobrazowe. Walory przyrodnicze wyróżnionych na badanym terenie siedmiu zbiorowisk roślinnych (4 zespołów - Angelico-Cirsietum oleracei, Arrhenatheretum elatioris, Lolio-Cynosuretum, Festuco-Cynosuretum oraz 3 zbiorowisk z gatunkiem dominującym: Poa pratensisFestuca rubra, zbiorowisko z Agrostis capillaris-Festuca rubra, zbiorowisko z Trisetum flavescens) określono na podstawie bogactwa gatunkowego wyrażonego liczbą gatunków ogółem, współczynnika różnorodności gatunkowej ShannonaWienera, wyrażonego wskaźnikiem H' oraz obecności gatunków chronionych i rzadkich. Fitocenozy te charakteryzują się dużym bogactwem gatunkowym od 34 do 150 gatunków. Wartości wskaźnika H’ kształtują się na średnim poziomie i wynoszą od 2,32 do 2,64. Najwyższą wartością współczynnika różnorodności charakteryzuje się zbiorowisko z Trisetum flavescens, a największym bogactwem gatunkowym Lolio-Cynosuretum. Spośród gatunków prawnie chronionych w Polsce odnotowano obecność: Carlina acaulis i Colchicum autumnale, a bliskich zagrożenia (NT) - gatunek Geranium sylvaticum. Bogactwo gatunkowe roślin, wysoki udział barwnie kwitnących w różnych porach sezonu wegetacyjnego ziół i chwastów oraz roślin z rodziny bobowatych wpływają na walory estetyczne i krajobrazowe analizowanych zbiorowisk łąkowo-pastwiskowych. Ich lokalizacja w krajobrazie urozmaiconym wzniesieniami, zagłębieniami terenu, podnoszą atrakcyjność badanych rejonów powiatu kłodzkiego.

    Opis:
    This study analyses the composition, species richness and diversity (H’) of aquatic molluscan communities in temporary water bodies within the valley of the lower Bug River in eastern Poland. The investigations were carried out in 2007–2009 within the section of the valley located between 190th and 50th km of the river course in 50 water bodies. Relatively rich and diverse malacofauna was found in the investigated habitats: 32 snail species and 6 bivalve species. Species diversity (H’) in individual water bodies ranged from 0.44 to 3.48. About 40% of all mollusc species showed frequencies of _10%. Dominance patterns varied much among the water bodies. Mollusc abundance ranged from 20 to over 1,800 indiv./m2. Considerable species richness and diversity were found both within the active floodplain and the former one. This was probably related to the long duration of many of the investigated water bodies, as well as their periodical hydrological connectivity with permanent ones or river channel. From 9 to 12 samples should be enough to compile representative species list of molluscs inhabiting temporary water bodies, but as many as 28–40 samples would be necessary to obtain complete dataset.

    Opis:
    Fires that are one of the most classic disturbance of plant communities have had a great impact on the development of Scots pine communities. Restoration of vegetation disturbed by fire in this type of community starts almost immediately after disturbance. The intensity of fire significantly influences the future composition of vascular plant species and also the rate of change. The aim of the study was to describe the effect of intensity of the surface fire on the forest floor vegetation response and to preliminary attempt to characterize the syndynamic processes occurring after the disturbance. The research was conducted in Scots pine forest Peucedano−Pinetum in the Kampinoski National Park (central Poland). We established 45 permanent study plots, including 17 not burnt (control) and 28 burnt ones. Each plot covered area of 100 m². On each plot at first we separated the areas which were not burnt, surface burnt and characterized by complete burnout of the organic horizon of the soil. Than we measured the thickness of this horizon. Additionally the volume of organic matter burnt within each plot was calculated. Vegetation was sampled using Londo scale in the year of fire (2015) and the year after (2016). We used DCA ordination and UPGMA classification methods. Recorded species were divided into forest and non−forest groups and additionally for trees and shrubs, and the others, containing dwarf shrub, herb, bryophyte and lichen species. The linear regression method was used to estimate the relationship between measured parameters, vegetation change and changes in the species richness of distinguished groups. Two processes of vegetation reaction were observed. The first was classified as regeneration and occurred within surface burnt plots. Its characteristic feature included the higher increase in forest species richness than in case of non−forest species. The other process was defined as secondary succession alike. It occurred on plots with highest burnout of soil organic matter horizon. The increase of richness of non−forest species predominated within it. The change between two processes is smooth and depends on the participation of area with complete burnout of soil organic horizon within plot. The results show, that more than one process of recovery of community can occur in the same site and it depends especially on the proportion of soil organic horizon area burnout.

    Opis:
    The knowledge on the ichthyofauna community in forest complexes in our country is mainly limited to few information on fish species found in rivers and reservoirs located in the protected areas. Hence, the aim of present study was to evaluate the importance of forested and non−forested areas, which include small rivers, on the occurrence of fish communities. The main criteria of evaluation were species richness, biodiversity and density of fish from rivers located in forested and non−forested areas in Roztocze and Puszcza Solska (south−eastern of Poland). The 12 study sites in the two groups of small rivers located on forested and non−forested areas were chosen (tab. 1). The control fishing was performed by electrofishing using IUP−12 gear. The total of 779 individuals of fish and lamprey belonging to 22 species were caught during the study. In the sections of rivers located in non−forested areas we noted 18 species, while in the rivers in forested areas – 16 ones. The analysis of the abundance domination showed that the dominant species in the rivers sections on non−forested areas were perch, roach and gudgeon, while in rivers located in forested areas: gudgeon, dace and brown trout. Simultaneously, in abundance of fish fauna from rivers in forested area a significant share of eastern sculpin, burbot and European brook lamprey were noted. The fish communities from both habitats showed similar values of biological diversity indices, but slightly higher density was observed in the rivers located in non−forested areas. The fish species composition was highly dependent on the close surroundings of the watercourse and the type of riparian zone. For the habitats from river located in non−forested areas the common, associated with aquaculture and also invasive fish species were characteristic. However, in the rivers in wooded areas, the typical for small streams and the rheophilic fish species were more frequent. The results of present study showed, that the largest differences in the dominance in fish structure and indicators of fidelity to the habitat preferences between the groups of rivers were determined.

    Opis:
    The composition and structure of the breeding bird community in the Borki Forest in north-eastern Poland were investigated during two separate periods: 1994–1996 and 2012–2014. Bird censuses were carried out in three plots located in mature oak-hornbeam, ash-alder and mixed coniferous forest stands. A standard combined mapping technique for estimating the number of breeding birds was applied. A total of 74 bird species bred at least once within any plot during 1994–1996 or 2012–2014. The structure of the bird assemblages on particular plots displayed a high degree of similarity, exceeding 75%, which means that they represent essentially the same bird community. However, the investigated assemblages have changed substantially over the 20 years. Both, the number of breeding bird species and the population densities on all plots, were much higher in 2012–2014 than in 1994–1996. The mean number of breeding species on all plots was over 50% higher in 2012–2014 than in 1994–1996, whereas the mean total density of breeding pairs increased by more than 60%. Total population densities on the plots increased as a result of an increase in population densities of individual bird species combined with an increase in the number of breeding species. Due to different rates of population growth for certain species, also the composition of dominating species group have changed. The observed changes in the avifauna of the Borki Forest were most probably due to an enrichment of the forest habitats structure, which was caused by natural factors, such as ageing of forest stands, forest succession and a change in water regime by beaver dams, as well as by forest management, including group felling within or in the vicinity of plots and uncovering of the forest edge.

    Opis:
    Alien tree species, due to their longevity, manifest their invasive potential after several decades from introduction. For the high threat to biodiversity, there is a need to analyze the risk of introduction connected with numerous alien tree species introduced in the various forest ecosystems. We aimed to assess the productivity potential and effect of alien Carya ovata on understory vegetation. Our study was conducted in the oldest (122 years old) tree stand of C. ovata in Poland, located in the Czerniejewo Forest District (western Poland). We analyzed C. ovata tree stand features and vegetation traits within the forest community and compared with natural vegetation – oak−hornbeam forest. We found that C. ovata trees had lower dimensions and standing volume than oaks (Quercus robur and Q. petraea) growing in the neighborhood. We also did not find the impact of C. ovata stands on understory vegetation species composition and light availability. Because of the low impact on forest floor vegetation and lack of spread we concluded that C. ovata cannot be classified as an invasive species. Moreover, its introduction was not successful in terms of tree stand productivity.

    Opis:
    Alternative methods of oak cultivation aim at reducing the cost of establishment of young plantations and decrease in the expenditure on their tending. In these methods, the corridors consisting of oak seedlings planted in the rows or isolated groups of twenty six seedlings are enclosed by stripes or patches without intervention left for natural succession. The restriction in site preparation on these areas and spontaneous development of young generation of trees are assumed to create favourable conditions for many forest organisms and, in results, significantly improve biological diversity of the managed forests. The aim of the study was to recognize the response of forest collembolan assemblages on alternative methods of establishment of oak plantations. The study was performed in the Forest Experimental Station in Rogów (Central Poland). In a mature stand on moderately humid mixed deciduous forest site, on clear−cut and on oak young plantations made by corridor and tree groups methods, fifteen study plots were established. In case of young plantations, these plots encompassed both artificially planted corridors or tree groups and adjacent fragments of plantation left for natural succession. Soil samples were taken in June and September 2014 and, using a simplified Tullgren apparatus, 18 thousands of collembolan specimens belonging to 84 taxa were identified. Our study proved that clear−cut and site preparation by rotary tiller on moderately humid mixed deciduous forest had a negative impact on Collembola assemblages, because caused a reduction in species number and abundance. However, the establishment of oak plantations by alternative methods, consisting in abandonment an artificial planting on some patches of renewed plots, significantly mitigate negative effects of clear−cut and reforestation on collembolan assemblages. The species number and abundance of springtails on patches left for spontaneous succession were distinctly higher than in artificially planted corridors or groups of trees in case of all studied plantations. Furthermore, it seems that corridor method in oak plantations establishment is advantageous for forest springtails, because the number of specimens per square meter on corridor plantation was higher than in tree group method. The beneficial effect on soil fauna of alternative methods of oak cultivation described in this paper weighs in favour of their wider application in silviculture.

    Opis:
    Observing wildlife at their natural habitat is practically a chance factor. However, there is alternative way by which it is possible to study the presence of wildlife and also their activities by indirect methods. North Bengal, especially Dooars is extreme rich in wildlife; therefore, there are many National Parks, Reserve forest as well as Wildlife Sanctuaries at this terrain. Studies on presence of wildlife by means of indirect evidences from different National Parks of Dooars reveals many untold stories. From this study it also evident that Dooars region is still harboring very good verities of wildlife, therefore, this is the demand of time to conserve these forests, as well as wildlife not only to save them from quick destruction but also to maintain human civilization.
