A wide variety of vertebrates likely opportunistically prey on Little Brown Bats, but no species are known to specialize on them, and surprisingly few have been confirmed as predators, including owls. Evidence of predation by owls on Little Brown Bats is limited to incidental records of predation by Eastern Screech Owls in the Great Lakes region and a Northern Saw-whet Owl in southeastern Alaska. Here, Jung et al document an observation of a Great Horned Owl (Bubo virginianus) preying on a Little Brown Bat in a mist net. They use mist nets to capture bats on the Lubbock River in southcentral Yukon Canada.

Context: Wolverines (Gulo gulo) are harvested for fur in northern Canada; however, the impacts of harvest are poorly known. Additionally, wolverine population data are largely absent for much of their northern range. Demographic data collected from harvested wolverines provide information on the vulnerability and variability of different sex and age cohorts to harvest, which, in turn, may have implications for harvest sustainability.Aims: We examined the temporal variability of different sex and age cohorts in wolverine harvest among years, and within the harvest season, in Yukon, Canada. We also examined the pregnancy status of female wolverines in relation to the harvest date, so as to evaluate the impact of the...

Aim We surveyed the genetic variability of deermice (genus Peromyscus) at the north-western edge of their range to test for occupancy in multiple, hypothesized ice-free regions during the late Pleistocene and explore post-glacial dynamics. Location North-western North America. Methods We used sequences from four independent nuclear and mitochondrial loci from 341 specimens of Peromyscus maniculatus, Peromyscus keeni and Peromyscus sp. (Yukon) to assess species limits, population structure, and demographical change as a result of historical climate change, using a Bayesian approach. Species distribution models were built in MaxEnt to explore the niche overlap amongst genetically distinct species. Results Divergence...
