Variability in marine resources affects arctic fox population dynamics [PDF]

Journal of Animal Ecology, 2003
SummaryTerrestrial predators in coastal areas are often subsidized by marine foods. In order to determine the potential impact on terrestrial prey, the numerical response of predators to each food source must be determined.In winter, arctic foxes (Alopex lagopus) may forage on the frozen Arctic ocean and scavenge carcasses of seals killed by polar ...

Rodent population cycle as a determinant of gastrointestinal nematode abundance in a low-arctic population of the red fox

International Journal for Parasitology: Parasites and Wildlife, 2019
We analyzed an 11-year time series (2005–2015) of parasite abundance for three intestinal nematode species in the red fox (Vulpes vulpes) as a function of the multi-annual rodent population cycle in low-arctic Norway, while correcting for other potential
