Little is known about the diversity, distribution, and relative abundance of bats in northeastern Alberta, Canada. Between 1999 and 2007, we conducted summer bat surveys in the Athabasca and Cold Lake oil sands regions of northeastern Alberta, in res

Some mammals in high northern latitudes show regular population cycles. In snowshoe hares (Lepus americanus), these occur every 9-10 years. One hypothesis proposes extrinsic causes such as food shortage or preda- tion. The other proposes intrinsic ca

Reproductive output was estimated for a cyclic population of snowshoe hares (Lepus americanus) in the Kluane Lake region of the southwest Yukon Territory. Data collected by five researchers were collated over 8 years (19891996). Pregnant hares were

Snowshoe hares (Lepus americanus) undergo a 10-year cycle in abundance, with cyclic changes in reproduction occurring 3 years prior to numeric changes. Reproduction may be associated with body condition, which might change with nutrition or predation

1. Survival rates and natalities for a population of snowshoe hares in the Yukon were estimated independently of and simultaneously with estimates of population change during the increase phase of a hare cycle. 2. Simple demographic models are used t
