Background. The relevance of the work is determined by the important role of the green toad in the trophic networks of natural and anthropogenic ecosystems of the forest-steppe zone, as well as the lack of information on this issue in the Tambov Province. The purpose of the study: to study the taxonomic composition and ecological characteristics of the food organisms of the green toad in the studied region.
Materials and methods. Used material was 36 specimens of green toads, caught in summer 2017 in two points of Tambov Province: the Rogozna village in Mordovsky District (17 specimens) and the vicinity of Pichaevo settlement in Zherdevsky District (19 ones). The method of autopsy and studying of the contents of the gastrointestinal tract was used.
Results. A total of 968 food organisms were found in the stomachs of 36 toads from two localities. Among them there are representatives of the types Annelida and Arthropoda. The basis of the diet consists of insects, especially Coleoptera (in the first place among preys of toads in the Rogozna village), Diptera (the same in vicinity of Pichaevo settlement), Hymenoptera (in second place in both localities), Hemiptera (in third place in vicinity of Pichaevo settlement). From other arthropods the myriapods are frequently consumed (in third place in the Rogozna village). Toads feed primarily on walking and running herpetobionts, often having a mixed type of nutrition (phytodetritophagous and phytozoodetritophagous), less zoophagous and phytophagous.
Conclusions. According to our data, the taxonomic composition of food organisms of the green toad in the Tambov Province differs on some peculiarities from the diet of the species in other regions. In addition, obtained data allow you to identify noticeable differences in the diet of toads, even living in geographically close places with similar environmental conditions.
