“…On the other hand, the results obtained in this study do not show a reduction in the brain case volume in farm animals. Bowman et al [2] are of the opinion that the lack of brain volume reduction in farm minks may be associated with the uncertain status of wild minks used in their study. If there are the descendants of escapees from farms among the wild population, their craniometric characteristics will oscillate towards the values being found for the parameters of farm minks.…”

“…We presumed that the geographical distribution and richness of prey species has not changed during the past 100 years (Graham and Mead 1987). Although some wild mink populations might now include escaped, feral minks (Bowman et al 2007), there are no data to suggest that feral minks (or resultant hybrids) have diets that differ from wild minks.…”

Historic fur returns from Hudson's Bay Company posts in northwestern Canada reveal periodic oscillations in mink (Neovision vision) harvests lagging 2-3 years behind oscillations in muskrat (Ondatra zibethicus) harvests, as would be expected in a predator-prey interaction. Toward central and eastern Canada, the strength of the interaction between time series of harvests of minks and muskrats weakens and the lag between fluctuations of these 2 species decreases to 1 and 0 years, respectively. We tested the hypothesis that this gradient in minkmuskrat interactions is the result of decreased dependency of minks on muskrats in areas where minks have access to more alternate prey. We tested 2 predictions: species richness of mink prey is greatest in eastern Canada and decreases to the west, and percent muskrats in the diets of minks decreases as species richness of mink prey increases. Contrary to the 1st prediction, we found that species richness of mink prey in Canada is highest in southcentral Canada. Consistent with the 2nd prediction, percent occurrence of muskrats in the diets of minks was much lower in areas with greater species richness of mink prey. Local species richness of mink prey therefore could influence the degree of specialization of minks on muskrats, but may be insufficient to explain the geographic pattern in the lag between muskrat and mink harvests in eastern Canada.

“…Given demonstrated global problems with mink farm biosecurity (Bonesi and Palazon 2007;Bowman et al 2007), there is potential for mink farms to be sources of cross-species spillover of AMDV (Nituch et al 2011(Nituch et al , 2012. Wildlife other than mink may also be sources of disease on farms (Farid 2013).…”

ABSTRACT:Aleutian mink disease virus (AMDV) occurs in the American mink (Neovison vison) in wild populations and on mink farms and can cause illness and death. The North American river otter (Lontra canadensis) may be exposed to AMDV because of shared space and habitat with mink. Using serology and real-time PCR, we tested river otters across Ontario for AMDV infection. We found no evidence of infection in otters, a surprising finding given the sympatric distribution, niche overlap, and close phylogenetic relationship of the river otter and the American mink. Our results are consistent with the hypothesis that the major point of spillover of AMDV between mink farms and wildlife is manure and composting carcasses on mink farms. Mink farms in Ontario are generally in agricultural landscapes; it is unlikely that river otter use these habitats and thus are likely not exposed to AMDV. We found no evidence that AMD is an important disease for the river otters in Ontario.
