Homage to Hersteinsson and Macdonald: climate warming and resource subsidies cause red fox range expansion and Arctic fox decline

Paleodistribution modeling suggests glacial refugia in Scandinavia and out‐of‐Tibet range expansion of the Arctic fox

Quaternary glacial cycles have shaped the geographic distributions and evolution of numerous species in the Arctic. Ancient DNA suggests that the Arctic fox went extinct in Europe at the end of the Pleistocene and that Scandinavia was subsequently recolonized from Siberia, indicating inability to track its habitat through space as climate changed. Using ecological niche modeling, we found that ...

Habitat and roe deer fawn vulnerability to red fox predation.

1. Notwithstanding the growing amount of literature emphasizing the link between habitat, life-history traits and behaviour, few empirical studies investigated the combined effect of these parameters on individual predation risk. We investigated direct and indirect consequences of habitat composition at multiple spatial scales on predation risk by red foxes on 151 radio-monitored roe deer fawns...

Distribution and abundance of genetic variation in the arctic fox

This thesis investigates how changes in population size and spatial movements of individuals have shaped the distribution and abundance of neutral genetic variation in the arctic fox (Alopex lagopus). This is done through mitochondrial and microsatellite DNA analyses on samples covering most of the species’ distribution, but with special emphasis on Scandinavia. On the species level, nucleotide...

Suspected Hip Dysplasia in a Red Fox

We report skeletal features that are consistent with hip dysplasia, as it is described in domestic dogs (Canis lupus familiaris) in a museum specimen of a red fox (Vulpes vulpes). Morphological identifiers included shallow acetabulae, femoral head flattening and subluxation, caudal curvilinear osteophyte, circumferential femoral head osteophyte, osteophytes of the acetabular margin, and femoral...
