We studied water frogs from a complex composed of two species: Pelophylax lessonae (Camerano, 1882) (genome LL, 2n = 26) and P. ridibundus (Pallas, 1771) (RR, 2 = 26), and their natural hybrid P. esculentus (Fitzinger, 1843) of various ploidy and genome composition (RL, 2n = 26, and RRL or RLL, 3n = 39). Tetraploids RRLL were found (4n = 52) in juveniles. We applied cytogenetic techniques: AgNO...

Body size is a central biological parameter affecting most biological processes (especially energetics) and the mitochondrion is a key organelle controlling metabolism and is also the cell's main source of chemical energy. However, the link between body size and mitochondrial function is still unclear, especially in ectotherms. In this study, we investigated several parameters of mitochondrial ...

Abstract Geographic peculiarities of population structure and hemicloning reproduction the water frog Pelophylax esculentus complex 904 samples within southern East European Plain were analyzed. The proportion populations P. ridibundus is 0.667 against those 0.042 lessonae . RE-type are most common among mixed ones (0.153). colonies two parental species kl. (REL-type), as well with (LE-type), h...

Amphibians, which can live in aquatic and terrestrial environments, are a good indicator of pollution these areas. Although frog leg is not consumed frequently some cuisines, including Turkey, it important terms evaluating metal accumulation since preferred as human food many European countries. In this study, the quantities trace elements (Cd, Pb, Cu, Zn, As, Co, Cr, Ni, Mn, V) were measured e...

Abstract The morphological and morphometric variability of the nematode Oswaldocruzia filiformis from ten amphibian species ( Pelophylax ridibundus, lessonae, esculentus, Rana arvalis, temporaria, Bufo bufo, Bufotes viridis, Pelobates vespertinus, Bombina bombina Lissotriton vulgaris ) was studied. sampling performed during period 2018–2020 in fifteen localities European Russia. We examined fol...

Transport infrastructures, such as highways, disrupt animal migrations and cause roadkill. To mitigate the latter problem, fences have been built but their effectiveness has rarely tested under controlled conditions. Here, we of most commonly used fence in France probably Europe (wire netting fence) to block animals. We wire fence, with without a structural modification (i.e. an overhang), thre...
