“…Moreover, only one animal in the sample showed a somewhat strong preference in its (right) forelimb use. This result is in well correspondence to previ-ous findings in other populations (Malashichev, 2002), all belonging to the same "Eastern" type of P. fuscus (Borkin, Litvinchuk, Rosanov, and Milto, 2001). Similarly, in both species of true frogs (Ranidae) examined, the more terrestrial Grass frog, R. temporaria (Fig.…”

Anuran amphibians represent the most usual subjects for experimental biological research and a divergent group of extant vertebrates comprising species adapted to a variety of environments from aquatic to arboreal. Thus, they become excellent models in research of motor lateralization due to their different phylogenetic position and their anatomical and ecological diversity throughout their evolutionary history, as well as variety of locomotive habits and a diversity of limb use during walking, swimming, feeding and other activities. From the first works in mid-1990's to the present day, a noticeable progress, a noticeable progress in the study of motor lateralization in anurans is made favored by a set of methodological approaches and their application to various species and life stages. Together, these advances foretell a plethora of interesting developments in the world of laterality research with the anuran amphibian model. Here, the discovery of right-pawedness in toads through the development of a set of different techniques to assess motor lateralization in anuran amphibians, and, as a consequence-important results revealing behavioral and morphological correlates are reviewed and discussed in evolutionary and eco-morphological perspective.

“…In total, 47 individuals were tested for nuclear DNA analysis (8 P. ridibundus, 4 P. lessonae and 22 P. esculentus). The technique is described in details previously (Borkin et al, 2001). The obtained results confirm the water frogs identity, P. ridibundus has 16.2 ± 0.1 pg of nuclear DNA (min-max: 16.1-16.3) P. lessonae -13.9 ± 0.1 pg (13.8-14.1) and P. esculentus -15.2 ± 0.1 pg (14.9-15.6).…”

Population systems of Eurasian water frogs (Pelophylax) in the south of Ukraine

et al. 2020

Ecological and evolutionary consequences of population-genetic processes that occur because of natural cross-species hybridization can show mechanisms of overcoming the reproductive barrier and obtaining the species status by a hybrid taxon. This is clearly seen in the population systems of Eurasian water frogs – Pelophylax esculentus complex. The P. esculentus (E) hybrid usually discards one of the parental genomes of P. lessonae (L) or P. ridibundus (R) and reproduces semi-clonally. The genetic structure and direction of gene flows precisely depend on the type and distribution of mixed or pure population systems of water frogs. Three population systems in the south of Ukraine were identified and confirmed as RR, RE and REL. The populations of P. ridibundus are most common (76.2%). A mixed population systems of P. ridibundus and P. esculentus (20.0%) are concentrated in the floodplains of large rivers where triploids were found and the unisexual hybrids (1.0♂ : 0.1♀) were proved. Parent species populations having different ploidy of P. esculentus such as 3n and for the first time 4n were found. A mixed system of three taxa (REL) is rare (3.8%) and locally concentrated in the lower Danube and Dnieper with the smallest proportion of P. lessonae. We did not find populations of P. lessonae (LL), P. esculentus (EE, very rare system of hybrids only), and two mixed populations of parental species RL and semi-clonal LE in the south of Ukraine, but they are known for northern areas. The high number of P. ridibundus tends to decrease; the scarce P. esculentus and the extremely rare P. lessonae require special conservation measures. P. ridibundus (RR) occupies a wide range of diverse natural, permanent, temporary, coastal, continental, and artificial freshwater bodies, including synanthropic ecosystems. Mixed population systems inhabit willow and poplar forests in the floodplains of large rivers. In the south of Ukraine rare and isolated populations of the water frogs occurring outside the main range can be relict. Biotopic preferences, ratio and number of constituent taxa are crucial for an adequate assessment of biological (taxonomic) diversity and development of an appropriate strategy for the population systems’ conservation. Such characteristics as unisexuality of hybrids, their spreading patterns, specific sex structure and ploidy in different population systems of the P. esculentus complex contribute to the understanding of the hybridogenetic dynamics; produce new tendencies of becoming independent hybridogenous taxa and emergence of new evolutionary relationships.

We studied the distribution of Palearctic green toads (Bufo viridis subgroup), an anuran species group with three ploidy levels, inhabiting the Central Asian Amudarya River drainage. Various approaches (one-way, multivariate, components variance analyses and maximum entropy modelling) were used to estimate the effect of altitude, precipitation, temperature and land vegetation covers on the distribution of toads. It is usually assumed that polyploid species occur in regions with harsher climatic conditions (higher latitudes, elevations, etc.), but for the green toads complex, we revealed a more intricate situation. The diploid species (Bufo shaartusiensis and Bufo turanensis) inhabit the arid lowlands (from 44 to 789 m a.s.l.), while tetraploid Bufo pewzowi were recorded in mountainous regions (340-3492 m a.s.l.) with usually lower temperatures and higher precipitation rates than in the region inhabited by diploid species. The triploid species Bufo baturae was found in the Pamirs (Tajikistan) at the highest altitudes (2503-3859 m a.s.l.) under the harshest climatic conditions.
