Opis:
Large tracts of natural habitat are being readily replaced by urban sprawl worldwide. We have limited knowledge about the anthropogenic activities on native species in these ecological regions. Human intervention has led to conversion of much of the global diversity by means of habitat alterations. Our conservation methods are also suffering from those superficial strategies. The present study was carried out to investigate the importance of habitat heterogeneity for the diversity, distribution and abundance of avifauna in and around Pench Tiger Reserve. In February 2014, a total of 79 bird species were recorded during the study period, applying the modified point count method. We compared species abundance and richness in Pench Tiger Reserve, considering four zones as metacommunity. Avifaunal community was distributed among Kolitmara (Western Pench, Maharashtra), Sillari (Maharashtra), Mansinghdeo (Maharashtra) and Seoni, Pench (Madhya Pradesh). Site specific biodiversity indices reflect the occurrence pattern of avifauna. Shannon – Wiener and Species diversity Index scored highest (9.56 and 1.78 respectively) in Mansinghdeo Wildlife Sanctuary. But species dominance was found high (0.62) in and around Sillari. Study areas with dense canopy closure were found to have more habitat specialist bird species, while areas having human settlements showed more opportunistic ones. An overall negative impact of human settlements on avian diversity, distribution and abundance was evidenced from the present study but more intensive study is needed to infer on the dynamics. Moreover, intensive studies may enrich us about avian diversity and distribution pattern of the study zone.

Opis:
Ground beetle communities found in the suburbs of wells of three oil fields of Khoiniki district (Republic of Belarus) were studied in the research carried out. These deposits are in the forest area. This research drew out that there is a growth in the number of species composition and abundance of ground beetles (Carabidae) in the exclusion zone due to the anthropogenic transformation of forest ecosystems. At the same time there is a reduction in representation in ground beetle communities of forest species in favor of meadow and field species to their total disappearance. The reduction occurs together with the growth of species abundance and number.

Opis:
Butterflies are very sensitive insects for climate change, environmental pollution. Butterflies are model for most of the studies which focus on the effect of climate change on the species richness, change in abundance, species distribution, population size; it is also because of butterflies are umbrella species,. The conservation programme of butterflies will surely help to conserve other species from plants to microscopic organisms. In this study an attempt was made to evaluate the change in butterfly population dynamics through different seasons of the year. According to the observation made during research period it is clear that species richness was the highest from August to November (Monsoon and Early Monsoon) followed by Winter. The lowest were in Hot Summer and Summer that is from February to May. This study is an example for the impact of climate change on the diversity of butterflies from semi-arid geographical region of India; revealed the impact of climate on the species composition, species richness and abundance of butterflies. Such studies are very much important to show that the effects of climate change whether it is natural or human induced change the species composition of species directly and indirectly effecting the ecosystem balance.

Opis:
The data on the distribution and number of the capercaillie Tetrao urogallus in Poland for the period from the end of the 20th century up to 2017−2018 is presented. The capercaillie is a sedentary forest grouse living in old mountain forests and within the boreal zone. Since more than a century, the decrease in the numbers of the species has been observed, interlinked with the extinction of isolated populations. Within the present borders of Poland, a 1925 questionnaire study noted 2200−2700 individuals. In the 1960s, the national population was estimated at 1700−2000 birds, living in five isolated populations. In 1985−1995, the population numbers of the capercaillie dropped to approx. 466−700 individuals in four regions, and in 2000 it was estimated at 470−570 birds. According to the results of the censuses performed in 2017−2018, the size of the capercaillie population risen to 523−631 individuals and 59−69 lekking grounds. Currently the capercaillie occurs in four isolated regions. These are the Western Carpathians (the Beskid Sądecki, Tatry, Gorce, Babia Góra, Beskid Żywiecki, and the Beskid Śląski ranges) where 284−326 individuals live and 35−41 leks are active. In the Solska and the Lasy Janowskie Forests (Lublin region), the population was estimated at 132−184 individuals and 12−13 lekking grounds. In the Augu− stów Forest (Podlasie region) 36−46 individuals and 5−7 leks were found. In the Bory Dolnośląskie Forest, where native capercaillies got extinct during the last decade, the reintroduction program resulted in the rebuilding of their 65−75 population (with 6−7 leks). The restitution of the species in the Piska Forest has begun. During the last 20 years, populations in the Carpathian national parks have been stable, although fluctuating in numbers. The increase in the number of individuals in the Augustów Forest as well as in the Sądecki and Beskid Śląski Mountains is an after−effect of the release of birds from breeding centers or translocations. In other strongholds, fluctuations or decreases have been recorded, including wisible in the Beskid Żywiecki Mountains.

Opis:
A full (i.e. close to completion) list of fauna of any city, nowhere was assessed, mainly because taxonomic and ecological diversity of invertebrates is beyond practical possibilities to have cooperation in the given area of all specialists, which would be necessary for such a study. The most comprehensive studies of this kind, in comparison to fauna of the region, were carried out in Warsaw (Poland), and more recently in Łódź (Central Poland). Within administration area of Warsaw (492 km2), about 3,800 species of terrestrial invertebrates from above 90 families or orders were recorded together with about 320 vertebrate species. The complete list of the animal world of Warsaw is estimated to be about 6-7 thousand species. The species richness of the fauna in large (European) city is likely to comprise 5-10 thousand of species, but the present knowledge about urban invertebrate wildlife does not allow even a basic assessment to be made. The vertebrate fauna is known much better, its species richness is similar in European cities - about 300-400 species. Total number of animal species recorded in Warsaw (ca. 4,100) is about 12% of that indicated from the whole country (Poland). If only vertebrates (a relatively well studied group) are compared - the proportion is 48-50%. In almost all of taxa studied, the species richness decreased with increasing urbanization gradient. The number of invertebrate species recorded in the green suburbs of Warsaw was 57% of that recorded in comparable studies in the region, in urban parks - 31%, and in small green patches in the city centre - 14%. As concerns breeding birds - in Warsaw as a whole about 65% of the species were found in comparison to the region whilst in the inner city - about 37%. Studies on abundance of urban fauna in Warsaw indicated that 1 m2 of soil layer in city lawns contains on an average several tens of thousands of invertebrate individuals whilst 1 m2 of ground surface - several hundred of them. 1 m3 of the canopy of the park trees contains 2-3 thousand individuals with more than one hundred of them per sample of 100 leafs. The total population of the breeding avifauna of Warsaw was estimated to be 150-350 thousand pairs (breeding territories) i.e. ca. 300-700 pairs per km2. The average density of the bird population in the highly urbanized areas of inner Warsaw was 830-1590 pairs per 1 km2 in the breeding season, and 2.5-4.5 thousand individuals per 1 km2 in winter. This is similar to values reported from other European cities.

Opis:
The presence of arbuscular mycorrhizal fungi (Glomeromycota, AMF) in soils may be crucial for sustainable agriculture. Although AMF impact on the performance and accumulation of therapeutic compounds of several medicinal plant species has been well documented, the investigations on the influence of medicinal plants being cultivated on AMF have been insufficiently studied. The effect of three-year monocultures of mycorrhizal (Hypericum perforatum, Levisticum officinale, Mentha × citrata subsp. citrata and Thymus vulgaris) and non-mycorrhizal (Chelidonium majus) medicinal plant species on AMF propagule abundance, species richness and composition was therefore examined. The AMF non-host plant species C. majus decreased the abundance of AMF propagules in the soil, whereas the mycorrhizal plants maintained the AMF propagule potential at the same level, however, they changed the composition of AMF species. The results showed that the choice of medicinal plant species, grown even for a relatively short period of time in a monoculture, can substantially alter the AMF potential of soils which in turn can influence the performance of other medicinal plants cultivated subsequently.
Obecność symbiotycznych grzybów arbuskularnych (Glomeromycota) w glebach może być istotna dla zrównoważonego rolnictwa. Chociaż wpływ tych mikroorganizmów na witalność i produkcję metabolitów wtórnych przez rośliny lecznicze był badany w ostatnich latach, niewiele wiadomo na temat oddziaływania uprawianych roślin leczniczych na te grzyby. Celem pracy było więc określenie wpływu trzyletniej uprawy mikoryzowych (Hypericum perforatum, Levisticum officinale, Mentha × citrata subsp. citrata i Thymus vulgaris) i niemikoryzowych (Chelidonium majus) gatunków roślin leczniczych na liczbę propagul, bogactwo oraz zróżnicowanie gatunkowe grzybów arbuskularnych. Uprawa C. majus spowodowała spadek liczby propagul tych mikroorganizmów w glebie. W przypadku roślin mikoryzowych dostępność propagul utrzymywała się na podobnym poziomie. Uprawiane rośliny miały jednak wpływ na skład gatunkowy grzybów arbuskularnych. Uprawa badanych roślin leczniczych na danym terenie, nawet przez stosunkowo krótki czas, wpływa na zmianę składu gatunkowego i dostępność propagul grzybów arbuskularnych w glebie, co w konsekwencji może mieć wpływ na witalność roślin leczniczych, zależnych od symbiozy mikoryzowej, uprawianych w przyszłości na tym terenie.

The aim of this paper is to determine the current biological state of life in the pelagic zone of the Gulf of Gdańsk in relation to the planned start-up of an underwater outfall which will discharge sewage from the Gdańsk–Wschód (Gdańsk–East) sewage treatment plant. The plankton material was collected during two research cruises in July and October 1998. The samples were taken at 15 stations in four profiles located near Wyspa Sobieszewska (Sobieszewo Island), perpendicular to the coastline. Both the taxonomic and numerical structure of phytoplankton and zooplankton were typical of the coastal area of the Gulf of Gdańsk. The species diversity depends on hydrological conditions, mainly input from the River Wisła (Vistula). The abundance and biomass of phytoplankton in 1998 were several times lower than in 1994 and 1995 in the area off Górki Wschodnie, the profile located closest to the planned construction site. This could have been caused by generally lower temperatures in 1998 in comparison to previous years. In the investigated area only traces of algal eutrophication indicator species were noted. However, potentially toxic species were confirmed and were most abundant near the Wisła mouth. The highest concentrations of pelagic fauna occur in the shallowest area closest to the shoreline. Long-term observations of the dynamics of the variations in abundance and species composition indicate the increasing significance of one particular species – Acartia bifilosa.

Opis:
In this study, the results of fish composition, distribution and abundance are presented according to the effects of water physicochemical parameters from the Livoq Lake in the eastern part of Kosovo. The fish specimens were sampled in six sampling stations in 2018 by using a variety of methods, including electro-fishing devices, fishing rod and cast nets. The measured physicochemical parameters included: water temperature, dissolved oxygen, saturation of dissolved oxygen, pH, conductivity, total dissolved solids. In total, 320 fish specimens were collected, belonging to 10 species of the following 5 families: Cyprinidae, Silurideae, Esocideae, Percideae and Centrarhideae. The most species rich family is Cyprinidae with 6 species in total: Cyprinus caprio Linnaeus, 1758, Rutilus rutilus Linnaeus, 1758, Carassius carassius Linnaeus, 1758, Squalius cephalus Linnaeus, 1758, Leucaspius delineatus Linnaeeus, 1758 and Alburnus alburnus Linnaeus, 1758. Four other families are represented by one species each: Silurideae with Siluris glanis Linnaeus, 1758, Esocidea with Esox lucius Linnaeus, 1758, Percideae with Perca fluviatilis Linnaeus, 1758 and Centrarhideae with Lepomis gibosus Linnaeus, 1758. The knowledge on fish fauna in Kosovo is still very fragmentary, and this investigation contributes to determining the qualitative composition and abundance features based on the water physicochemical parameters in this part of the Balkan Peninsula.

Opis:
The research was carried out in the economic and natural Forest Reserve ‘Yertys Ormany’ in Pavlodarsk Oblast (Kazakhstan) in 2018. In the middle of May, two barrier traps of the ‘Netocia’ type (30, in total) were installed on each research plot damaged by wind, fire and great pine web – spinning pine sawfly – Acantholyda posticalis Mats. Insects were caught every month, from mid−June to mid−August. 1521 insects belonging to 67 species and 23 families were caught in the traps. Beetles clearly dominated. We also observed a great pine web and sirex woodwasp Sirex noctilio Fabr. Of the beetles caught, 10% were thermophilic jewel beetles or metallic wood−boring beetles Buprestidae, among which Chalcophora mariana (L.) dominated. The highest average number of individuals was observed on sites damaged by A. posticalis, however, differences between the plots turned to be insignificant. The highest significant average number of species was observed on sites damaged by the fire and by the wind. The GLM analysis indicated the highest mean values of the Margalef index in plots damaged by fire and by the wind, but did not show significant differences between the average values of the fidelity index of the assemblages. The research confirmed the hypothesis of a greater number of species and individuals, and a higher diversity of pests in pine stands more strongly disturbed (i.e. damaged by the fire and by the wind). At the same time, there were no differences between the most seriously disturbed variants.

Opis:
The aim of the study was to analyse the changes in abundance and species composition of dung beetles (coprophagous Scarabaeoidea) inhabiting Scots pine stands in various stage of the development. Beetles were collected in baited traps in Człuchów Forest, Pomeranian Lake District (NW Paland). In total we collected 87,596 specimens representing 41 species (tab. 2). The structure of dung beetle communities inhabiting analysed Scots pine stands changes in the course of the forest developmental cycle. Lands adjoining to a forest, clear−cut areas and plantations are inhabited by heliophilous communities of dung beetles, with superdominant species Trypocopris vernalis and dominant species such as Anoplotrupes stercorosus, Aphodius pedellus, Euorodalus coenosus and Chilothorax distinctus (tab. 2, fig. 5a). Thicket stage, pole timber stage, and the mature stand are inhabited by umbrophilous dung beetle communities characteristic for pine stands, with superdominant species Anoplotrupes stercorosus and dominant species Trypocopris vernalis (tab. 2, fig. 5b). At thicket stage the number of dung beetles species is dramatically reduced in comparison to other developmental stages (fig. 3). Moreover, a fundamental change in species composition is observed.

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.
