Although natal dispersal has received considerable attention from animal ecologists, the causes and consequences of breeding dispersal have remained largely unexplored. We used telemetry, direct observation, and long-term mark-recapture (9 yr) to study breeding dispersal in the North American red...
Intraspecific cache pilferage in larder-hoarding red squirrels (Tamiasciurus hudsonicus) in Kluane, YukonDownload
Pilfering is thought to play a role in the evolution of scatter-hoarding strategies; but is not well understood in larder-hoarding animals. I studied intraspecific pilfering in red squirrels in Kluane, YT, Canada. The purpose of this project was to estimate the natural rate of cache pilferage,...
Nest predation on forest songbirds in a western boreal forest landscape altered by energy sector linear featuresDownload
Nest predation is a major source of reproductive failure for many species of songbirds. Habitat fragmentation by human land use creates edge habitat that can alter predator-prey dynamics, create ecological traps, and reduce the amount of high quality habitat available for sustaining bird...
Resources and Reproductive Trade-offs Affect Fitness, Life History Traits, and Sexual Selection in Red SquirrelsDownload
Animals face trade-offs throughout life between competing functions, such as between self-maintenance, reproduction, and survival. Resource allocation between these competing functions leads to different patterns of life history traits, changes in investment in reproductive effort, and different...
Food availability, energetic ceilings, and life-history trade-offs have been proposed as potential determinants of offspring number in many animals. We investigated the role of these factors in determining litter size in a free-ranging population of red squirrels (Tamiasciurus hudsonicus)....
