Pelophylax esculentus is a hybridogenetic frog originating from matings between P. ridibundus (RR) and P. lessonae (LL). Typically, diploid hybrids (LR) live in sympatry with one of their parental species, upon which they depend for successful reproduction. In parts of their range, however, pure hybrid populations can be found. These hybrid populations have achieved reproductive independence fr...

Stormwater ponds (“SWPs”) are artificial roadside structures, conceived to retain and clean polluted runoff water, before its release the environment. SWPs were not designed as suitable habitats for wildlife. However, in Europe frequently used breeding sites by amphibians, especially European green frog (Pelophylax sp.). Yet, potential long-term effects of pollutants within on populations this ...

The article presents the results of a study peripheral blood erythrocytes dominant animal species in Turkestan region. relevance this work is due to construction nuclear power plant on territory Uzbekistan (Jizzakh region, Lake Tuzkan), since areas region fall under potential influence plants and biota objects require monitoring at ‘zero stage’ before plant. data obtained are great importance a...

Determining the invasibility of habitats by alien species is crucial for understanding their spread potential, most at risk and to implement adequate management actions. This urgent introduced taxa that show high invasion potential across broad geographical scales. We here assess these processes in invasive Pelophylax water frogs which are widespread colonizers Western Europe remains be quantif...

Large-scale systematic patterns of body size are a basic concern of evolutionary biology. Identifying body size variation along altitudinal gradients may help us to understand the evolution of life history of animals. In this study, we investigated altitudinal variation in body size, age and growth rate in Chinese endemic frog, Pelophylax pleuraden. Data sampled from five populations covering a...

In this paper, we assess the environmental impact of urbanization in three freshwater biotopes, using levels fluctuating asymmetry (FA) 10 meristic morphological traits Marsh Frog (Pelophylax ridibundus (Pallas, 1771)). Two studied biotopes are located boundaries city Plovdiv (one central part, other a suburban residential area), and third is vicinity village Orizare. Our working hypothesis bas...
