Poisoning caused by coumarin-type anticoagulant rodenticides (ARs) stands as the
predominant method for controlling rodents globally. ARs, through secondary poisoning …

Abstract The Eastern Imperial Eagle (EIE) is a top predator exploiting different prey in
different parts of its distribution. In this study, we summarise data collected over a long …

The Optimal Foraging Theory predicts that, to maximize fitness, animals adapt their foraging
strategy that provides the most benefit for the lowest cost, maximizing the net energy gained …

Top predators may adapt their diets to changes in prey availability where human-induced
environmental changes are intense. This long-term study of the breeding-season diet of …

Predator–prey interactions may be linked to different temporal or spatial patterns, including
dynamics in prey populations. Therefore, understanding the adaptive capacity and how top …

Apex scavengers can perform an important ecosystem service by rapidly removing carrion,
in turn regulating nutrient cycling linked to carcass decomposition. Yet, our understanding of …

The European ground squirrel (EGS) is an endangered burrowing rodent of Central and
South-Eastern European dry grasslands with a declining population trend. Its prehistoric and …

The common hamster (Cricetus cricetus) occupies a controversial position among mammals
inhabiting agricultural areas, as it is possibly the only critically endangered species that is …

Abstract The Eastern Imperial Eagle is a globally threatened species, represented with not
more than 35–40 pairs in Bulgaria. As a facultative scavenger feeding on carcasses and …

Habitat alteration is a widespread threat severely affecting large raptors because of their low
density and the huge area they inhabit. In this study, we assessed whether human-driven …
