  • Dec 2024
European water frogs from the Pelophylax esculentus complex include two sexual species, P. ridibundus and P. lessonae, and their hybrids, which usually clonally transmit one of the parental species' genomes. This unique reproductive strategy allows hybrids to reproduce with one or both parental species, creating diverse population systems. Unlike m...

For each individual, we photographed all countable mitotic 212 chromosomes and manually counted the number of chromosomes and pericentromeric loci after third of the chromosomes lacked strong signals and LLR if two-thirds did (Fig. S2, A, C, E, ...

... study examines the temporal changes in the occurrence and distribution of various frog forms 286 across five R-E-Ep HPSs (Fig. 2, Table S2). Over nine and eight years of monitoring HPS 287 composition in DOB and ISK, respectively, we consistently found diploid P. esculentus to be the 288 dominant form, ranging from 62% to 85% in DOB and from 82% to 96% in ISK annually. Triploid 289 individuals ranged from 7% to 26% in DOB and from 0% to 10% in ISK. Additionally, ...

... revealed fluctuations in genetic composition and taxon ratios over time within the studied 404 population systems. Proportions of different forms have been changing significantly through the 405 years (Fig. 2). However, within past years these HPSs tended to remain more stable with diploid 406 hybrid males being the prevailing form. In ISK we even observed a decrease in P. ridibundus 407 within the past years. Earlier research has suggested that the anticipated consistency in water frog with a simultaneous decline in P. lessonae was shown in ...
