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.
