Harvest Mouse

The Western Harvest Mouse (Reithrodontomys megalotis) is rare in Canada, and its distribution is believed to be restricted to south-central British Columbia and southeastern Alberta. Between 2008 and 2010, we identified Western Harvest Mouse hairs in 71 of 1424 scats (5%) of Red Fox (Vulpes vulpes), Coyote (Canis latrans), American Badger (Taxidea taxus), and Long-tailed Weasel (Mustela frenata) collected in southwestern Saskatchewan. The presence of Western Harvest Mouse was confirmed at the same latitude as populations reported in Alberta and British Columbia, in scats collected in or nearby grasslands. This is the first time that the presence of the Western Harvest Mouse has been confirmed in Saskatchewan.

Striped Skunks

We assessed sex ratio, body mass, and harvest rates for 5 species of carnivores (Mammalia: Carnivora) collected in southern Saskatchewan, Canada during spring and summer 1999-2001. Overall, 647 adult carnivores were collected; captures consisted mostly of Striped Skunk (Mephitis mephitis, 50.7% of captures, 2.6±0.6 kg), Raccoon (Procyon lotor; 28.3%, 6.5±1.3 kg), American Badger (Taxidea taxus, 8.2%, 7.7±1.5 kg), Red Fox (Vulpes vulpes, 7.7%, 4.6±0.6 kg), and Coyote (Canis latrans, 5.1%, 11.0±1.5 kg). Sex ratio (M:F) of captures was male-biased for Raccoon (2.5:1), Striped Skunk (1.7:1), but did not differ from 1:1 for American Badger (2.3:1), Coyote (1.7:1), or Red Fox (2.2:1). For both Striped Skunk and Raccoon, the temporal variation in sex ratio of captures suggests that males were more vulnerable to capture early in the spring than females. Harvest rates were highest for Striped Skunks (range 0.8-2.2 animals/km2) followed by Raccoons (0.4-1.3 animals/km2), American Badgers (0.2-0.5 animal/km2), Red Foxes (0.2-0.4 animal/km2), and Coyotes (0.1-0.4 animals/km2).

Changes in the relative abundance of sympatric carnivores can have far-reaching ecological consequences, including the precipitation of trophic cascades and species declines. While such observations are compelling, experimental evaluations of interactions among carnivores remain scarce and are both logistically and ethically challenging. Carnivores are nonetheless a particular focus of management practices owing to their roles as predators of livestock and as vectors and reservoirs of zoonotic diseases. Here, we provide evidence from a replicated and controlled experiment that culling Eurasian badgers Meles meles for disease control was associated with increases in red fox Vulpes vulpes densities of 1.6–2.3 foxes km −2 . This unique experiment demonstrates the importance of intraguild relations in determining species abundance and of assessing the wider consequences of intervention in predator populations.

This paper demonstrates the influence of artificial selection on morphometric traits in the red fox [Vulpes vulpes (Linnaeus, 1758)]. Measurements and two proportion coefficients were analysed in 132 wild and 199 farm red foxes. The two groups differed significantly (P ≤ 0.05) on all but one of the measurements. Eight out of 11 measurements were significantly greater in the farm fox population, while only tail length, ear height, and length of the right hind limb were greater in the population of wild foxes. The opposite trend was observed when analysing variation in the measurements — the farm foxes were characterized by a greater variability only in the case of body weight, body length, and breadth of chest. When analysing the sexual dimorphism index in different sex and population groups, in almost all analysed traits, the greatest differences occurred between farm males and wild females. All of the traits examined in this study are important for survival of wild foxes. However, because importance of some traits was reduced during domestication and selective breeding (farm foxes do not have to fight for survival), the genetic relationship between them may have weakened. Other possible causes of morphological differences between the studied groups of red foxes are discussed as well.
