Vocalization in anurans is mainly studied in the context of male-specific advertisement calls, while release calls – characteristic of both sexes – usually attract less attention. Here we compare release calls of both sexes of hybrid Pelophylax esculentus (considering triploid hybrids) and its parental species P. ridibundus in Ukrainian population...

Some related species give rise to interspecies hybrids with hemiclonal inheritance. The gametes of such hybrids transfer the set of hereditary information of one of the parental species. The water frog, Pelophylax esculentus, is an example of such hybrids. The hemiclonal hybrids together with their parental species form a biosystem for which the su...

Interspecific hybridization can disrupt canonical gametogenic pathways, leading to the emergence of clonal and hemiclonal organisms. Such gametogenic alterations usually include genome endoreplication and/or premeiotic elimination of one of the parental genomes. The hybrid frog Pelophylax esculentus exploits genome endoreplication and genome elimin...

We propose a modified and updated protocol to obtain mitotic chromosomes from the regenerated tissue of Pelophylax tadpole tail tips. Chromosomal preparations from regenerated tissue results in high-quality and clean slides suitable for further staining and study. Tadpoles remain alive, undergo minimum suffering, and can be grown to adulthood for f...

Pelophylax esculentus is an interspecies hybrid of marsh frog P. ridibundus and pool frog P. lessonae. The hybrids are usually presented by diploid and triploid forms, and coexist and crossbreed with one or both parental species in the hemiclonal population systems (HPS). Siverskyi Donets river basin is known for its diversity of HPS and was descri...

Studying any system requires development of ways to describe the variety of its conditions. Such development includes three steps. The first one is to identify groups of similar systems (associative typology). The second one is to identify groups of objects which are similar in characteristics important for their description (analytic typology). Th...

Three R-E-Ep-HPS of Siverskyi Donets center of Pelophylax esculentus complex diversity have been studied. Each system has specific features of composition and dynamics. HPS of the Iskov pond approximates to E-HPS, HPS of the Koryakiv ravine’s pond and the Lower Dobrytskyi pond – belongs to E-Ep-HPS. HPS number of the Iskiv pond’s HPS is evaluated a...

We propose hypothesis that defines hemiclonal inheritance as a rare natural evolutional way to overcome interspecies hybrid sterility (as well as clonality and polyploidy). The main consequences of hemiclonal inheritance are clonal evolution of genomes and homological interspecies recombination. On the example of hybridogenic Pelophylax esculentus...

Background Interspecies animal hybrids can employ clonal or hemiclonal reproduction modes where one or all parental genomes are transmitted to the progeny without recombination. Nevertheless, some interspecies hybrids retain strong connection with the parental species needed for successful reproduction. Appearance of polyploid hybrid animals may pl...

Cattle grazing is a traditional agricultural activity and one of the obligatory factors for maintaining steppe ecosystems. The impact of grazing depends on its intensity, site area, soil, topography, and microclimatic conditions. Both intensive grazing and long-term cessation differently affect various components of the steppe biota. During the res...

Hybridization and polyploidy play an important role in animal speciation. European water frogs of the Pelophylax esculentus complex demonstrate unusual genetic phenomena associated with hybridization, clonality and polyploidy which presumably indicate an initial stage of reticulate speciation. The Seversky Donets River drainage in north-eastern Ukr...

Pelophylax esculentus is an interspecific hybrid which reproduces hemiclonally by crossing with the parental species (P. ridibundus or P. lessonae). The structure of hemiclonal population systems is of great interest. The majority of investigations into populations of water frogs deal with samples of mature animals, while subadults are less studied...

Polyploidization is a rare yet sometimes successful way for animals to rapidly create geno- and phenotypes that may colonize new habitats and quickly adapt to environmental changes. In this study, we use water frogs of the Pelophylax esculentus complex, comprising two species (Pelophylax lessonae, genotype LL; Pelophylax ridibundus, RR) and various...

Incompatibilities between parental genomes decrease viability of interspecific hybrids; however , deviations from canonical gametogenesis such as genome endoreplication and elimination can rescue hybrid organisms. To evaluate frequency and regularity of genome elimination and endoreplication during gametogenesis in hybrid animals with different plo...

Background Hybridogenesis (hemiclonal inheritance) is a kind of clonal reproduction in which hybrids between parental species are reproduced by crossing with one of the parental species. European water frogs (Pelophylax esculentus complex) represent an appropriate model for studying interspecies hybridization, processes of hemiclonal inheritance an...

Hybridogenesis represents one of known clonal ways by which interspecies hybrids can be reproduced. During hybridogenesis, gametogenesis proceeds with deviations, when one of the parental genomes can be eliminated while the other one can be endoreduplicated. Among natural interspecies hybrids, Pelophylax esculentus as a hybrid between P. ridibundus...

Based on DNA flow cytometry, we identified green frog localities with hybrid Rana esculenta. We found or confirmed some southernmost localities of the species situated in Moldavia and Ukraine. According to our data, the southern distributional border of R. esculenta is demarcated as follows from the west to the east: Vilkovo (Danube River Delta), V...

A triploid female (3n = 33) was found in diploid species Bufo viridis from the Crimea Peninsula, Ukraine. The case is recognized as an occasional autotriploidy. No morphological differences were found between this triploid female and other diploid specimens of the sample. Three categories of triploids in the Bufo viridis group are clas-sified. Base...

Substantive provisions of rational environmental ethics are stated. This concept presumes to compare a level of uniqueness of different objects, which forms the establishment for giving the ethical value. The developed approach is used for comparison of 26 populations of Bufo viridis Laurenti, 1768 from Left-bank forest-steppe of Ukraine.

Mass triploidy in hybrid Rana esculenta was revealed by means of DNA flow cytometry in 19 localities of eastern Ukraine (Kharkov, Donetsk, and Lugansk provinces). Triploids consist of two groups in terms of parental species genomes: LLR and LRR. The both groups were recorded in population systems of the E and R–E types. Two tetraploids were found a...

In eastern Ukraine, the Rana esculenta complex consists of three species: R. lessonae, R. ridibunda, and hybrid R. esculenta. The first one was rare, whereas two latter frog taxa were very common. Based on DNA flow cyto-metry, mass occurrence of the triploidy in Rana esculenta has been revealed in 14 localities of Kharkov, Do-netsk, and Lugansk Pro...

Population biodiversity of green (Bufo viridis) and common (Bufo bufo) toads in the Left-bank Forest-steppe of Ukraine has been studied. Most studied samples show statistically significant differences by many characters. Interpopulation fenetic intervals exceed the intrapopulation intervals between the groups, and in certain cases – intervals betwe...
