Description:

Our aim was to determine biogeographical patterns in the food habits of golden jackals by first reviewing their dietary patterns at the continental scale and then analysing associations between the food items in their diets and geographical, regional productivity and land-use variables, using multivariate analyses. Our findings indicated that jackals generally consume small mammals as a staple food but shift to consume plant materials or the carcasses of larger mammals when food resources are scarce owing to changes in the regional climate and productivity, as well as anthropogenic habitat modifications. Disruption of natural food resources (specifically small mammals) due to anthropogenic landscape modifications provokes dietary shifts in golden jackals, potentially increasing their reliance on anthropogenic resources. Consequently, conservation of their habitat in combination with waste management to decrease the accessibility to anthropogenic resources is required to resolve human-jackal conflicts.
