ABSTRACT
Background:
In open terrestrial biomes of Holarctic realm, ground squirrels are recognised as keystone species inhabiting steppes. They shape the plant species composition and diversity and support a fauna of species associated with their burrows. Ground squirrels and associated dung-beetles are important elements of the steppe food webs, yet the trophic associations between species are still poorly studied. New information The area in the northern outskirts of Obshchy Syrt plateau, on the border of Samara and Orenburg Provinces of Russia was surveyed and scarab beetles (Scarabaeidae) feeding on steppe marmot (Marmotabobak (Müller, 1776)) faeces were collected from six localities. Twenty eight species of two subfamilies - Aphodiinae and Scarabaeinae, - were identified with the majority of species belonging the genus Aphodius Hellwig, 1798. Seven species are recorded as consumers of marmot faeces for the first time. Only two nidicolous specialist species were found which suggests that the studied population of steppe marmots is as result of the recent secondary colonisation and not all the associated scarab beetle faunas were re-established.
