Habitat factors influencing beaver dm establishment in a northern Ontario watershed
Article Abstract:
Most beaver dam establishment studies rely on plant composition as habitat determinants. However, a proper understanding of dam-site selection should also include physical features. A new study, designed to test the theory that beaver dam sites on sections of boreal streams are related to both the plant composition and physical attributes of the site, compares species composition and physical features of dam sites in the Swanson River drainage basin of the Chapleau Crown Game Reserve, ON. The study shows that beaver dam sites favor stream sections with dense woody vegetation and stem diameters of between 1.5 cm and 2.4 cm.

Survival of radiocollared adult moose in lower Susitna River Valley, southcentral Alaska
Article Abstract:
The result of 11 years of radiotelemetry data was summarized to estimate adult moose survival rates in southcentral Alaska, where there are fairly low predator densities. The method of capture for radiocollaring was mostly darting from a helicopter, and capture related deaths are not included in the analysis. Survival estimates were separately computed for males and females using the staggered entry Kaplan-Meier procedure. Survival rates were highly influenced by winter survival, which in turn was closely linked to snow accumulation.

Timber-management and natural-disturbance effects on moose habitat: landscape evaluation
Article Abstract:
The hypotheses that Ontario's Moose Habitat Guidelines for timber harvest create improve habitats and mitigate the effects of unchanged clearcuts on moose populations, is evaluated. Five study landscapes were compared, including land disturbed by wildfire burn and timber management, and those with and without hunter access. Neither land disturbance or hunter access effects were significant, with population rate of increase positive in both the burn and unchanged clearcut. There was no population increase in the modified clearcut.
