To determine whether exposure to fox odor alters granule neuron production, we examined proliferating cells and their progeny in the dentate gyrus of adult male rats exposed to trimethyl thiazoline, a component of fox feces. Additionally, to determine whether this effect is adrenal hormone-mediated, we examined animals exposed to fox odor after bilateral adrenalectomy and replacement with low l...

An Allee effect (AE) occurs in populations when individuals suffer a decrease in fitness at low densities. If a fitness component is reduced (component AE), per capita population growth rates may decline as a consequence (demographic AE) and extinction risk is increased. The island fox (Urocyon littoralis) is endemic to six of the eight California Channel Islands. Population crashes have coinci...

Three decades have passed since the Arctic fox (Vulpes lagopus) was first put into a population genetic perspective. With the aim of addressing how microevolution operates on different biological levels, we here review genetic processes in the Arctic fox at the level of species, populations and individuals. Historical and present dispersal patterns, especially in the presence of sea ice, are th...

The blue fox, belonging to the family Canidae, is a coat color variant of the native arctic fox (Alopex lagopus). To date, microsatellite loci in blue fox are typically amplified using canine simple sequence repeat primers. In the present study, we constructed an (AC)n enrichment library, and isolated and identified 17 polymorphic microsatellite markers for blue fox. The number of alleles per l...

Oral vaccination campaigns to eliminate fox rabies were initiated in Slovenia in 1995. In May 2012, a young fox (Vulpes vulpes) with typical rabies signs was captured. Its brain and salivary gland tissues were found to contain vaccine strain SAD B19. The Basic Logical Alignment Search Tool alignment of 589 nucleotides determined from the N gene of the virus isolated from the brain and salivary ...
