Asymptomatic viral infection is associated with lower host reproductive output in wild mink populations.

Many endemic viruses circulate in populations without hosts showing visible signs of disease, while still having the potential to alter host survival or reproduction. Aleutian Mink Disease Virus (AMDV) circulates in many American mink (Neogale vison) populations in its native and introduced ranges. In this study, we analysed how AMDV infection in female American mink affects the reproduction of a feral population.

The genetic diversity and structure in the European polecat were not affected by the introduction of the American mink in Poland.

The introduction and expansion of an invasive non-native species could have important consequences for the genetic patterns and processes of native species, moreover if the new arrival competes strongly for resources and space. This may result in the demographic decline of the native species. Knowing the effects on the levels of genetic diversity and structure in native species is key in terms of their conservation.

Digestive tract nematode infections in non-native invasive American mink with the first molecular identification of .

Parasites may negatively affect hosts condition, especially when infection intensity is high. Species introduced to a new habitat are often less exposed to a parasite pressure but may accumulate parasites in time. American mink () introduced to Europe, Asia, and South America is an example of such invasive species.

Spatial variation in anthropogenic mortality induces a source-sink system in a hunted mesopredator.

Lethal carnivore management is a prevailing strategy to reduce livestock predation. Intensity of lethal management varies according to land-use, where carnivores are more intensively hunted on farms relative to reserves. Variations in hunting intensity may result in the formation of a source-sink system where carnivores disperse from high-density to low-density areas.

Reduced Genetic Diversity and Increased Structure in American Mink on the Swedish Coast following Invasive Species Control.

Eradication and population reductions are often used to mitigate the negative impacts of non-native invasive species on native biodiversity. However, monitoring the effectiveness of non-native species control programmes is necessary to evaluate the efficacy of these measures. Genetic monitoring could provide valuable insights into temporal changes in demographic, ecological, and evolutionary processes in invasive populations being subject to control programmes.

Over-seasonal and sex-independent expression of kappa casein gene (CSN3) in mammalian blood lymphocytes.

After observing the nonspecific expression of the alpha S1 casein gene in peripheral blood mononuclear cells of goats, we continued to trace illegitimate gene-expression patterns in mammals. Six mammalian species (Bos taurus, Capra hircus, Ovis aries, Equus caballus, Sus scrofa, and Bison bonasus) were analyzed for the presence of kappa casein in peripheral blood mononuclear cells and Ficoll-isolated lymphocytes. To detect potential relationships between the expression pattern and reproductive status of the individual, the animals within species represented different sex, age, and physiological status (immature and reproducing males; immature, pregnant, lactating, and sterile females).

Landscape barriers reduce gene flow in an invasive carnivore: geographical and local genetic structure of American mink in Scotland.

To be effective, management programmes geared towards halting or reversing the spread of invasive species must focus on defined and defensible areas. This requires knowledge of the dispersal of non-native species targeted for control to better understand invasion and recolonisation scenarios. We investigated the genetic structure of invasive American mink (Neovison vison) in Scotland, and incorporated landscape genetic approaches to examine resultant patterns in relation to geographical features that may influence dispersal.
