Summary

This thesis evaluates how developmental conditions influence settlement, survival, and yearling primiparity in juvenile red squirrels. This was accomplished by comparing the fates of offspring from food supplemented versus non-supplemented mothers, and by using logistic regression to evaluate the effects of body mass, resource availability, and reproductive parameters on juvenile success. Maternal nutrition, previous and present year's cone production, and body mass contributed significantly to settlement and survival during all juvenile life history stages (emergence, settlement, and overwinter survival). Heavier than average juveniles were also more likely to reproduce as yearlings. Nevertheless, natal body mass was not a predictor [...]
