Home range, habitat selection, density, and diet of golden jackals in the Eastern Plains Landscape, Cambodia.

We used radiocollars and GPS collars to determine the movements and habitat selection of golden jackals () in a seasonally dry deciduous forest with no human settlements in eastern Cambodia. We also collected and analyzed 147 scats from jackals to determine their seasonal diet and prey selection. The mean (± ) annual size of home-range ranges (47.

Arctic foxes as ecosystem engineers: increased soil nutrients lead to increased plant productivity on fox dens.

Top predators can provide fundamental ecosystem services such as nutrient cycling, and their impact can be even greater in environments with low nutrients and productivity, such as Arctic tundra. We estimated the effects of Arctic fox (Vulpes lagopus) denning on soil nutrient dynamics and vegetation production near Churchill, Manitoba in June and August 2014. Soils from fox dens contained higher nutrient levels in June (71% more inorganic nitrogen, 1195% more extractable phosphorous) and in August (242% more inorganic nitrogen, 191% more extractable phosphorous) than adjacent control sites.
