abstract = {Browsing and bark peeling by ungulates is known to affect biodiversity and may constitute the main driving factor of single tree population dynamics. In Slovakia, European yew (Taxus baccata L.) is a threatened species protected by law and present in many protected areas. In the study, we emphasize that protecting land and individual plants may not be sufficient for maintaining of yew populations, unless controlling over damage by deer game is also undertaken. Our results show that in beech forests of the Veľká Fatra Mts, browsing and bark peeling constitute the main negative factor affecting yew seedling-sapling ingrowth transition, and the mortality and vitality loss of adult yew trees. We argue that ungulates may have a larger effect on biodiversity conservation than currently realized.},

abstract = {This paper examines the role of ecological factors, derived from principal component analysis performed on edaphic and vegetational dataset as well as spatial variables, in structuring the soil macrofauna community of the Dnipro floodplain within the ‘Dnipro-Orilsky’ Nature Reserve (Ukraine). The soil macrofauna was defined as invertebrates visible to the naked eye (macroscopic organisms). The test points formed a regular grid with a mesh size of 3 m with 7 × 15 dimensions. Thus, the total test point number was 105. At each point, soil-zoological samples of 0.25 × 0.25 m were taken for quantifying the soil macrofauna. The spatial structure was modeled by a set of independent spatial patterns obtained by means of principal coordinates of neighbor matrices analysis (PCNM-variables). Spatial PCNM-variables explain significantly more variations of the community (19.9%) than edaphic factors (4.1%) and vegetation factors (3.2%). Spatial and combined environmental and spatial effects were divided into three components: broad-scale component was characterized by periodicity of spatial variation with a wavelength of 24.0–44.5 m, medium-scale – 11.1–20 m, fine-scale 6.6–11.0 m. For a broad-scale component, environmental factors of a vegetational nature are more important, for medium-scale, edaphic factors are more important, for fine-scale, both vegetation and edaphic are important. For litter-dwelling animals, the most characteristic spatial patterns are on the broad and medium-scale levels. For endogeic and anecic animals, the most significant variability is on the fine-scale level.},

abstract = {Modelling the influence of different concentrations of lead and cadmium ions upon a laboratory culture of insects has not been adequately studied. In our research, we assessed the influence of cadmium and lead nitrates at different concentrations (10–2–10–9 М) upon the development of larvae, pupae and imagines of Calliphora vicina Robineau-Desvoidy, 1830 (Diptera: Calliphoridae). We found an acceleration in the development of larvae and an increase in mass of puparia when lead ions were added to the food of the larvae, and decrease in the mass of puparia when cadmium ions were added. We registered nanism and malformation of the fly imagines in experiments with lead and cadmium in the food substrate. We observed that under the influence of the studied heavy metal ions there was a reduced motor activity of the fly larvae at all stages of development, a delay in formation of puparia and a delay in the emergence of imagines in comparison with the control group.},

abstract = {Climatic factors and related changes of the temperature, humidity and sunshine demonstrably affect the
population dynamics of small mammals. This complex influence gets more intense in the case of natural and
anthropic disturbances which occurred in the forest ecosystems of the High Tatra Mts in 2014 (wind calamity)
and in 2015 (forest fire). During the period of research in 2005–2015, we were observing successive changes
in the species composition, abundance and spatio-temporal distribution of small mammals on the seven
permanent research areas by using the CMR method. Besides the changes of selected habitat variables, we
were also continually measuring values of meteorological elements (such as air and soil temperature, relative
air and soil humidity, thickness and duration of snow cover). Statistical testing of the thickness and duration
of snow cover proved significant influence of these factors on the population dynamics of small rodents
(Rodentia) and shrews (Soricomorpha). Winters with a thicker snow cover and longer snow periods had
a positive effect on the reproduction and surviving of both taxonomic groups in the subsequent vegetation
season. We have discovered the positive correlation between the temperature and the quantity dynamics of
dominant small rodents while shrews responded to higher temperatures with less spatio-temporal activity.
Gradient analysis of the complex influence of measured meteorological elements proved species-specific
differences in the responses of small mammals to the current and conditions of weather indicated by ecological
requirements of plant species within a specific habitat.},
