Data from: Exploration profiles drive activity patterns and temporal niche specialization in a wild rodent

Elouana Gharnit, Patrick Bergeron, Dany Garant & Denis Réale
Individual niche specialization can have important consequences for competition, fitness, and ultimately population dynamics and ecological speciation. The temporal window and the level of daily activity are niche components that may vary with sex, breeding season, food supply, population density, and predator’s circadian rhythm. More recently, ecologists emphasized that traits such as dispersal and space use could depend on personality differences. Boldness and exploration have been shown to correlate with variation in foraging patterns, habitat...

Consumption of red maple in anticipation of beech mast-seeding drives reproduction in Eastern chipmunks

Mathilde Tissier, Denis Réale, Dany Garant & Patrick Bergeron
1. Understanding the determinants of reproduction is a central question in evolutionary ecology. In pulsed resources environments, the reproduction and population dynamics of seed consumers is driven by pulsed production of seeds by trees, or mast-seeding. In Southern Québec, eastern chipmunks (Tamias striatus) exclusively reproduce during the summer before and the spring after a mast-seeding event of American beech. They thus seem to anticipate beech mast by reproducing during early summer, so that juveniles can...
