Pelophylax lessonae

Species composition and population systems of green frogs (Pelophylax esculentus complex) (Ranidae, Amphibia) in the Khoper River valley

Three species of green frogs (Pelophylax esculentus complex) have been identified in the Khoper River Valley. The marsh frog P. ridibundus is the most widespread and found in all the studied localities. The pond frog P. lessonae and edible frog P. esculentus have been recorded only in the floodplain of the Khoper River in the Khoper State Nature Reserve (Novokhopersk district of the Voronezh region) and in the extreme northwest of the Volgograd Region.

ON THE NUTRITION OF SOME SEMI-AQUATIC AMPHIBIAN SPECIES (AMPHIBIA: ANURA) IN THE NORTHWESTERN UPPER OKA REGION

The nutrition of Bombina bombina and Pelophylax lessonae collected in three habitats of the northwestern Upper Oka region in 2006 - 2014 was studied. The feed composition of Pelophylax lessonae reduced to the autumn by the abundance and taxonomic diversity, epigeious beetles and ants to predominate. Bombina bombina mainly feeds on ants and arachnids in the autumn.
