Life history strategies of northern form Dolly Varden (Salvelinus malma malma) in the western Canadian ArcticDownload
Northern form Dolly Varden char (Salvelinus malma malma) inhabit cold-water streams in the western Canadian Arctic. They are an important cultural and subsistence resource to local Aboriginal communities, yet little is known about their complex early life histories. Populations of Dolly Varden...
The relationship between individual performance and nonrandom use of habitat is fundamental to ecology; however, empirical tests of this relationship remain limited, especially for higher orders of selection like that of the home range. We quantified the association between lifetime reproductive...
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...
Mating systems evolve in response to factors that influence the distribution and availability of mates. In turn mating systems can influence species life histories as a result of sexual selection. Most of what is known about sexual selection in large mammals comes from long-term studies of...
