Triggers and biological processes controlling male or female gonadal differentiation vary in
vertebrates, with sex determination (SD) governed by environmental factors or simple to …

Environmental variation in the Anthropocene involves several factors that interfere with
endocrine systems of wildlife and humans, presenting a planetary boundary of still unknown …

Palearctic water frogs (genus Pelophylax) are an outstanding model in ecology and
evolution, being widespread, speciose, either threatened or threatening to other species …

Many species of amphibians in Northern Europe are threatened and the local distributions
are rarely described in detail. Application of modern molecular methods provides an …

In order to study the diversity, phylogenetic relationships and distribution of marsh frogs of
the Pelophylax ridibundus complex in Kazakhstan and northwest China, we conducted …

Alien species can strongly impact local environments and compete against native species,
which can lead to their extinction. Marsh frogs of the Pelophylax ridibundus complex are one …

The edible frog, Pelophylax esculentus, is a hybrid form that reproduces via clonal
propagation of only one of the parental genomes through generations of hybrids while the …

Hybridization and polyploidy play an important role in animal speciation. European water
frogs of the Pelophylax esculentus complex demonstrate unusual genetic phenomena …

Purpose The study aims to characterise and compare the helminth assemblages and
helminth infracommunities in the marsh frog, Pelophylax ridibundus and the edible frog, P …

Studying the distribution of morphologically cryptic animal species is always a very difficult
task. Because most marsh frog species (the Pelophylax ridibundus complex) are cryptic, we …
