Survival of Eurasian lynx in the human-dominated landscape of Europe.

Survival and cause-specific mortality rates are vital for evidence-based population forecasting and conservation, particularly for large carnivores, whose populations are often vulnerable to human-caused mortalities. It is therefore important to know the relationship between anthropogenic and natural mortality causes to evaluate whether they are additive or compensatory. Further, the relation between survival and environmental covariates could reveal whether specific landscape characteristics influence demographic performance.

Enhancement of 5-Aminolevulinic Acid-Mediated Photodynamic Inactivation of Using Phosphoric and Bisaminophosphinic Acids as Permeabilizing Agents.

The purpose of this work was to examine the effect of phosphoric and bisaminophosphinic acids on the effectiveness of photoinactivation of with 5-aminolevulinic acid (5-ALA) as a precursor of protoporphyrin IX. Two diode lasers λ = 404 nm (radiation intensity 26 mW cm) and λ = 630 nm (radiation intensity 55 mW cm) were used as sources of light. The most effective agent was ()-(-)-1,1'-binaphthyl-2,2'-diylhydrogen phosphate, and a significant improvement in bactericidal effect of 5-ALA-aPDI was achieved by pretreating with this compound at nontoxic concentrations of 0.

Molecular Identification of Selected Cervid Helminths in Supplementarily Fed European Bison Population.

Wild animals often suffer from infections with multiple species of parasites simultaneously. The exchange of parasites between different host species is common in nature and often involves intermediate hosts or sharing space such as pastures or watering holes. Supplementary feeding, leading to large aggregations of individuals, can have several adverse effects on wild ungulate populations, despite being a widespread management practice.

Impact of global environmental changes on the range contraction of Eurasian moose since the Late Pleistocene.

Climatic oscillations are considered primary factors influencing the distribution of various life forms on Earth. Large species adapted to cold climates are particularly vulnerable to extinction due to climate changes. In our study, we investigated whether temperature increase since the Late Pleistocene and the contraction of environmental niche during the Holocene were the main factors contributing to the decreasing range of moose (Alces alces) in Europe.
