Opis:
The paper discusses the impact of clear−cutting and artificial regeneration on species composition of the fresh coniferous Vaccinio vitis−idaeae – Pinetum association Sokoł. 1981. The studies were conducted in the maturing artificially established stands (of 55−77 years) and 150−180 year−old natural old−growth stands in the Polish and Belarusian part of the Białowieża Primeval Forest. No quantitative and qualitative differences were found in species composition and structure between the two groups of stands. The lack of significant differences between the two development stages was ascertained using ecological indicator values. In the maturing stands the non−forest species were not found, and all species (so−called euphytes??), characteristic of the Vaccinio vitis−idaeae – Pinetum association, were already present there. This means that the use of a clear cutting system emulating the catastrophic natural disturbance pattern of forest dynamics in this association did not entail permanent changes in the ground vegetation.

Opis:
A numerical analysis of the phytosociological relevés from ancient and recent woodland on a mesic forest site in central Poland was carried out. Three groups of forest stands were recognised: planted with Pinus, recent and ancient oak-hornbeam Tilio-Carpinetum. The species of ancient woodland occurred mainly in ancient oak-hornbeam forest stands, however some ferns: Dryopteris carthusiana, D. dilatata and D. filix-mas, and an orchid species Epipactis helleborine, are to be found mainly or exclusively in recent forests. The occurrence of ancient forest species in recent woods may be putatively explained by long-distance wind dispersal or by the thriving in situ in unrecognised small wood patches. Twelve ancient woodland indicators (i.e. 36% of a total number found in the region under study) occur exclusively in ancient woodland. It underlines the role of passive species protection in the maintenance of the regional species diversity.

Opis:
Presence of plant species, associated with ancient forests (continuous existence >200 years) can be used for assessing woodland biodiversity. The aim of this study is to specify which plant species, included in the ancient forests plant species list, can indicate old woodlands in parks and what plant features are characteristic for certain habitat types. Richest in ancient forest plant species are those fragments of woodlands, which have existed continuously for at least 120 years, and their fragments suffered least from human pressure during that time, whereas recent woodlands are characterized by a small share of ancient forest indicator species and domination of nitrophilous species. Investigated plants usually propagate vegetatively, their seeds are of a small size and they have regularly, densely set leaves. Plants associated with ancient woodlands are good indicators of woodland continuity in parks so they can be used for age assessment in these areas. Accumulation of such plants can be a useful criterion in parks evaluation. Proposed idea of sustainable management of a park space, including selection of areas of a great ecological value, can be a chance to preserve woodland biodiversity.

The paper analyses the relationships between the microsite diversity of fresh coniferous forest and the number of Scots pine (Pinus sylvestris L.) seedlings from natural regeneration. The competition of forest floor vegetation (mainly of Vaccinium myrtillus) was found to be the decisive factor of pine regeneration. Lichens, especially Cladonia arbuscula and C. rangiferina, as well as mosses, e. g. broom moss (Dicranum scoparium) and pincushion moss (Leucobryum glaucum), can be regarded as the indicator species for the microsite suitable for pine regeneration.

Opis:
The intensity of disturbance plays a key role in shaping the biodiversity and hence it is a good tool for assessing community changes occurring in the Western Bieszczady, an area depopulated after World War II. Based on sampling of acidophilous mountain beech forest phytocoenosis repeated after 50 years, an analysis of plant biodiversity changes was conducted. The study focused on changes in the number of species, Shannon’s indicator, spatial distribution and coverage of specific ecological groups of species. The results confirm an undergoing process of regeneration of straitened phytocoenoses from 1958−1961, in which a slow improvement of the trophic conditions can be observed.

Opis:
Vegetation of deciduous forests in the Štiavnické vrchy Mts (Central Slovakia) was studied using the standard Zürich-Montpellier approach. The numerical classification and ordination technique were applied to determine the main forest vegetation types and to find the responsible environmental drivers related to their distribution patterns, respectively. The data set including 198 relevés collected by authors in 1997-2009 and 185 relevés excerpted from literature was used to analysis. Numerical classification resulted in delimitation of fourteen vegetation types representing eleven associations with two variants and two communities within the Quercetea roboripetraeae and Querco-Fagetea classes. The major environmental gradients in variation of forest species composition were associated with moisture and nutrient content following the average Ellenberg indicator values. Along the moisture gradient, vegetation types were ordered from subxerophilous oak forests turn mesophilous mixed oak-hornbeam, beech and ravine forests to hygrophilous riparian alder forest. The results confirmed important role of soil nutrients and moisture by determination of forest vegetation in subcontinental part of Central Europe. Special attention was given to the discussion of floristical characteristics, site conditions and syntaxonomy.

Opis:
In the Chęciny district, xerothermic grasslands developed on deforested slopes of limestone hills, truncated folds, and mounds. Their origin is directly connected with agricultural and pastoral farming of man. Xerothermic grassland belongs to the class Festuco-Brometea, and the alliance Cirsio-Brachypodion. The plant association Thalictro-Salvietum pratensis is the most widespread in this area. The xerothermic grasslands have their own characteristic biota of macromycetes. The following steppe, xerothermic, and thermophilous fungi deserve special attention: Agaricus bernardii, Camarophyllus virgineus, Conocybe sienophylla, Entoloma incanum, Hygrocybe konradii, H. persistens, H. reae, Lepiota alba, and Leucopaxillus lepistoides. As a result of the xerothermic swards being progressively overgrown by shrubs and trees, among others, by Pinus sylvestris, one can find fungi species accompanying this tree: Suillus collinitus, also fungi producing underground fruit bodices Rhizopogon obtextus and Rh. roseolus. The main factors threatening xerothermic grasslands of the Chęciny district are, among others, the devastation and disappearance of natural habitats, often as a result of inappropriate human land management as well as the pollution of air, water, and soil. The effective protection of rare, threatened, and also legally protected fungi species is only possible by protecting their natural habitats as a whole.
W Okręgu Chęcińskim murawy kserotermiczne rozwinęły się na odlesionych zboczach wapiennych wzgórz, skib i pagórków. Ich powstanie związane jest ściśle z rolniczą i pasterską gospodarką człowieka. Murawy te należą do klasy Festuco-Brometea i związku Cirsio-Brachypodion. Najbardziej rozpowszechniony na tym terenie jest zespół Thalictro-Salvietum pratensis. Murawy posiadają własną dla nich charakterystyczną biotę grzybów wielkoowocnikowych. Na uwagę zasługują grzyby stepowe, kserotermiczne i ciepłolubne: Agaricus bernardii, Camarophyllus virgineus, Conocybe sienophylla, Entoloma incanum, Hygrocybe konradii, H. persistens, H. reae, Lepiota alba, Leucopaxillus lepistoides. W związku z postępującym zarastaniem muraw krzewami i drzewami, między innymi Pinus sylvestris, odnotowuje się gatunki grzybów, które towarzyszą temu gatunkowi sosny: Suillus collinitus oraz wytwarzające owocniki podziemne: Rhizopogon obtextus i Rh. roseolus. Do głównych czynników zagrażających murawom kserotermicznym Okręgu Chęcińskiego należą między innymi: zanikanie i dewastacja siedlisk naturalnych, spowodowane często poprzez niewłaściwą gospodarkę człowieka oraz zanieczyszczenie powietrza, wody i gleby. Skuteczna ochrona rzadkich, zagrożonych, a także prawnie chronionych gatunków grzybów możliwa jest tylko poprzez ochronę naturalnych ich siedlisk traktowanych jako całość.

Opis:
The species composition and size-structure of the phytoplankton community in the Boka Kotorska Bay (SE Adriatic Sea) were analysed with respect to abundance and carbon biomass, together with the physico-chemical parameters, with the aim of evaluating the predefined oligo-mesotrophic status of this transitional water ecosystem. Three stations located in the inner part of the Bay were sampled with seasonal frequency in 2008/2009. Picophytoplankton cells were counted using flow cytometry; nanophytoplankton and microphytoplankton were identified and counted by light microscopy. The relative importance of the picoplankton in the Bay, in terms of both abundance and biomass, during all the investigated seasons emphasized their significance in the phytoplankton community. Picocyanobacteria (Synechococcus) constituted a significant part of the summer assemblages with regard to both abundance (up to 3.38 × 108 cells L−1) and carbon biomass (up to 73% of total phytoplankton carbon). The contribution of the nanophytoplankton was found to be generally low (<20% of the total phytoplankton carbon) in all seasons, and was dominated by autotrophic/mixotrophic flagellates. Species with a preference towards nutrient-enriched conditions, like the diatom Skeletonema marinoi, dominated the microphytoplankton fraction. S. marinoi was the most abundant in spring/winter (up to 2.86×106 cells L−1) above the halocline (making a 96% contribution to the microphytoplankton). The potentially toxin-producing diatom Pseudo-nitzschia pseudodelicatissima was recorded at abundances greater than 105 cells L−1, together with Thalassionema frauenfeldii, as well as the dinoflagellates Prorocentrum micans and the potentially harmful P. minimum. The higher values of phytoplankton biomass and the dominance of phytoplankton species or groups with preferences for nutrient-enriched conditions appear to be consistent with the oligo-mesotrophic status of this specific ecosystem.

Opis:
Seslerio uliginosae-Scorzoneretum purpureae is the only xerothermic community of the Festuco-Brometea class, where a rare species known as Sesleria uliginosa occurs in Poland. A couple of sites hosting this association in the Nida Basin were described in the 1920s and 1950s. All these stands are now situated in the areas designated as xerothermic nature reserves. The study aimed at describing the present-day characteristics of this rare association, the most likely being endemic in Poland, as well as the changes that have occurred in it. The species diversity and the contribution of xerothermic plants have decreased significantly in terms of their number and cover coefficient. Some of the diagnostic species of the association have become extremely rare. Sesleria uliginosa is the only one without visible changes in their dominant position in the community. Mosses, that have played a significant role before, were among the vanished species. At the same time, an increase in number and cover of mesophilous meadows species was observed. Mesophilous grasses belong to the group of species growing in significance in the phytocoenoses. The observed changes in species composition were reflected in a statistically significant increase of nitrogen indicator value. The slow process of succession observed in the Seslerio-Scorzoneretum purpureae could be attributed to the lack of appropriate land use, e.g. mowing and grazing that have been ceased in the nature reserves.

Opis:
Biomass reduction and amino acid content in plants of Papaver rhoeas L. and Stellaria media L. were investigated to evaluate response of these species to herbicide stress under various temperature (25/16 and 8/2 oC) and relative humidity (50 and 75%) regimes. Weeds were treated with tribenuron methyl (15 g × ha-1), a mixture of 2.4-D with florasulam (180 + 3.75 g × ha-1), and a mixture of 2.4-D with dicamba (1252.5 + 97.5 g × ha-1). The fresh weight of weeds and the content of free branched-chain amino acids (valine, leucine and isoleucine) in plant tissue were recorded. Tribenuron methyl was the herbicide that most limited biomass productivity, regardless of weed species and climate conditions. S. media was more sensitive to herbicides than P. rhoeas. Weed response to herbicides was dependent on temperature, but not on relative humidity. Tribenuron methyl applied to both weed species under various temperature regimes caused significant amino acid deficiency. The reduction in amino acid content in plants of P. rhoeas was greater at warm temperature compared to the cold regime due to stronger reaction to tribenuron methyl applied under these conditions. In most of cases, the mixture of 2.4-D + dicamba induced overproduction of amino acids.
W pracy określono redukcję biomasy oraz zawartość aminokwasów w roślinach Papaver rhoeas L. i Stellaria media L. w celu oceny reakcji tych gatunków na stres herbicydowy w zróżnicowanych warunkach temperatury (25/16 i 8/2 oC) i względnej wilgotności powietrza (50 i 75%). Rośliny potraktowano tribenuronem metylu (15 g × ha-1), mieszaniną 2,4-D z florasulamem (180 + 3,75 g × ha-1) i mieszaniną 2,4-D z dikambą (1252,5 + 97,5 g × ha-1). Określono świeżą masę chwastów i zawartość wolnych aminokwasów o łańcuchach rozgałęzionych (waliny, leucyny i izoleucyny) w ich tkankach. Herbicydem najsilniej ograniczającym produktywność biomasy był tribenuron metylu, niezależnie od gatunku chwastu oraz czynnika klimatycznego. S. media była bardziej wrażliwa na herbicydy niż P. rhoeas. Reakcja chwastów była zależna od temperatury, natomiast nie była zależna od wilgotności powietrza. Tribenuron metylu zastosowany w zróżnicowanych warunkach temperaturowych spowodował znaczący ubytek zawartości aminokwasów w obu gatunkach chwastów. Redukcja zawartości aminokwasów w roślinach P. rhoeas była większa w warunkach ciepłych w porównaniu z chłodnymi, z powodu silniejszej reakcji na tribenuron metylu aplikowany w tych warunkach. W większości przypadków, mieszanina 2,4-D + dikamba wywoływała zwiększoną produkcję aminokwasów.

Opis:
The increase of Lyme borreliosis (LB) can be expected due to climate change, while the distribution of the disease and annual activity of the vector and host animals depend on several factors of the environment. The presented study aimed to assess expressly the spring season temperature dependence on the incidence of LB in Hungary. The weekly LB data were obtained from the National Epidemiologic and Surveillance System for a period of 13 years – 1998–2010. Daily temperature data were derived from the European Climate Assessment and Dataset. The association was studied at national level, descriptive statistics and linear regression models were applied. A significant increasing trend was observed in the mean temperature of the analysed years (0.052 °C per year). The annual LB incidence doubled during the 13 year period. The incidence rates of the periods 1998–2001 and 2007–2010 were 11.1 resp. 17.0 per 100,000. The start of a steep increase in weekly LB incidence (0.1 per 100,000) shifted significantly by 3 weeks earlier, the start date of spring showed similar trend (p=0.0041). LB incidence increased more steadily in spring than in summer, with 79% of the increase being reported during weeks 15–28, with maximum rates of increase occurring in weeks 23–25. The trend was significant between the weeks 15–28. In the warmer years with 19.02 °C mean temperature in May and June, the LB incidence curve reached the annual peak 2–3 weeks earlier, and the descending phase of the curve started earlier than in the colder years with 17.06 °C of the same period.
