The feeding ecology of the golden jackal (Canis aureus L., 1758) and its interspecific trophic relationship with the sympatric red fox (Vulpes vulpes (L., 1758)) was investigated in an area of recent range expansion of the golden jackal in Hungary, central Europe. Diet composition was determined by scat analysis (over 4 years: jackal 814 scats; fox...
Article
Studying food partitioning of mammalian predators is important for understanding trophic structures and interactions between coexisting carnivore species. This is particularly pertinent in the light of expanding ranges of populations of generalist species whose habitat and diet overlap with more specialized species. Here, we tested the resource par...
Article
The Eurasian golden jackal (Canis aureus) is currently undergoing a rapid range expansion. Originally restricted to small coastal areas of the Mediterranean and Black seas, this highly adaptive and generalist species is now reproducing throughout Southeastern and Central Europe. In addition, individuals are being seen further to the North and West....

Species range expansions and (re)colonization of landscapes variously dominated by humans occur on a global scale. Understanding such range enlargements and subsequent changes in the composition of ecological communities is important for conservation management, and the golden jackal (Canis aureus) can be considered a model species for regional and...
Article
During the last half-century, the distribution of golden jackals (Canis aureus) has rapidly increased throughout Europe. Today, golden jackals are thriving in human-dominated landscapes across Southeastern and Central Europe. Most studies on golden jackals have focused on large-scale distribution patterns; to date, little is known about the species...

The feeding of the stone marten (Martes foina) and the red fox (Vulpes vulpes) being flexible, easily adapt to anthropogenic food sources, utilising them effectively. Both carnivores feed on plants, thus the question arises how their food composition changes during the seasons when there is high availability of fruits in their habitat. The diet com...
Article
In a changing environment, dietary patterns of mammalian predators are influenced by many factors. In an agricultural area in south-western Hungary, where the red fox (Vulpes vulpes) is the top predator and has a stable population, our aim was to analyse how the diet composition based on scat samples changed over a longer period (first survey occas...

Little is known of the resources that limit or promote the rapidly expanding golden jackal (Canis aureus) population in Europe. We hypothesised that in an area of intensive big game hunting, a reduction of the main food resource (human subsidised big game viscera) would result in dietary switching. We used multivariate analyses to test whether the...

Prey selection by carnivores can be affected by top-down and bottom-up factors. For example, large carnivores may facilitate food resources for mesocarnivores by providing carcasses to scavenge, however mesocarnivores may hunt large prey themselves, and their diets might be affected by prey size and behaviour. We reviewed jackal diet studies and de...
