  • Contrary to what is observed in Fennoscandia, it seems to be widely accepted that small mammals do not exhibit multi-annual population cycles in the boreal forest of North America. [...] Key Method With information collected from existing data-bases, we examined the presence of cycles in small mammals and their main avian predators by using temporal autocorrelation analyses. Winter invasions of boreal owls (Aegolius funereus) were periodic, with a 4-yr cycle in Quebec. Populations of one species of small mammal…Expand Abstract
