Population dynamics of little brown bats () at summer roosts: Apparent survival, fidelity, abundance, and the influence of winter conditions.

White-nose syndrome (WNS) has caused the death of millions of bats, but the impacts have been more difficult to identify in western North America. Understanding how WNS, or other threats, impacts western bats may require monitoring other roosts, such as maternity roosts and night roosts, where bats aggregate in large numbers.Little brown bats () are experiencing some of the greatest declines from WNS.

Grey flesh fly (Wohlfahrtia vigil) parasitism of a Preble's meadow jumping mouse (Zapus hudsonius preblei).

A Preble's meadow jumping mouse (Zapus hudsonius preblei) parasitized by five grey flesh fly (Wohlfahrtia vigil) larvae was discovered at the United States Air Force Academy in Colorado Springs, Colorado (USA), in June 1998. This is the first documented case of grey flesh fly parasitism of jumping mice (Family Dipodidae). The lesion was approximately 6 mm wide and was partially hidden under a mat of wet fur.
