Snowshoe hares can have three or four litters over a summer, with five leverets on average
in each litter. All hares begin to breed in spring when they are 1 year old, so age at sexual …

populations include vole cycles in the boreal zone of Eurasia, lemming cycles in the high …

Optimal behavior theory suggests that prey animals will reduce activity during intermittent
periods when elevated predation risk outweighs the fitness benefits of activity. Specifically …
