TL;DR: Measurements of a controlled effect of predation risk along a 3350-kilometer north-south gradient across arctic Canada provides evidence that the risk of nest predation decreases with latitude, and evidence that birds migrating further north may acquire reproductive benefits in the form of reducedpredation risk.

TL;DR: It is concluded that species in the boreal forests of Canada do not exhibit the strong synchrony found between voles and other members of the vertebrate community in northern Fennoscandia.

TL;DR: A monitoring technique is evaluated that can be used to follow many vertebrate species simultaneously at low cost and requires little training of personnel and is generally an accurate reflection of variation in population size.

TL;DR: Seven bird species, representing shorebirds, passerines, a bird of prey, and seabirds, nesting on Herschel Island, Yukon, Canada, in the years 1984–1986 and 2007–2009, showed trends to earlier lay dates in conjunction with earlier snowmelt.

TL;DR: This work gathered qualitative and quantitative data on hare numbers and fur returns of Canada lynx in the boreal forest regions of Alaska, Yukon, Northwest Territories, and northern British Columbia to describe synchrony in the time window of 1970-2012.
