The problem of mountain rivers that needs to be carefully studied and taken into account when formulating regional water management policies is flow regulation. Any hydraulic structure on rivers that regulates the flow or slows it down affects the life of the river ecosystem. Dams segment the river, creating physical barriers to fish migration. The...

The distribution of the European grayling and huchen have been studies using several sources of data including ichthyological surveys, analysis of anglers’ and poachers’ catches, interviewing of local fisheries inspectors, forestry inspectors, and some local people, etc. As the results show, the European grayling is very widespread in the Transcarp...
Conference Paper
Full-text available
During ichthyological studies in 2017 we discovered a number of new species for the region (Perccottus glenii Dybowski, 1877, Pseudorasbora parva (Temminck et Schlegel, 1846), Ameiurus melas (Rafinesque, 1820)), due to the availability of museum samples, it is expected what in that territory was a Proterorhinus marmoratus (Pallas, 1814). So, from 1...

Reptiles of the order Testudines – turtles – are one of the most vulnerable and threatened groups of terrestrial vertebrate animals. The instances of their invasion or reintroduction are isolated and have only local importance. However, there is a bright exclusion. Slider turtle, Trachemys scripta elegans, does not only express a marked tendency to...

In this study, quantitative analysis of paternal genome inheritance by a hybrid form Rana “esculenta” (= Rana esculenta L., 1758 × Rana ridibunda Pall., 1881) (Amphibia, Ranidae) was examined. The hybrid form examined was characterized by a polymodal mode of inheritance (genome of any of the parental species can be inherited). The absence of correl...

The biochemical genetic marking and analysis of the ploidy and sexual structure of the green frog populations from the Transcarpathian lowlands have demonstrated that this region is inhabited by the unisexual populations composed of the allodiploid females only. Their genome includes a small portion of the marsh frog genic diversity. This phenomeno...
