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: Asynchrony between hatch and peaks in Tipulidae biomass reduced growth rates in chicks of Baird's Sandpiper, and the effects of asynchrony on growth rates of arctic-nesting birds warrant further investigation.

TL;DR: The authors' analysis provided little evidence that herbivores are limited by primary production on Bylot Island, but measured strong predator-prey interactions, which supports the hypothesis that this food web is primarily controlled by top-down forces.

TL;DR: In this article, an analysis of the Bylot Island food web in the Canadian Arctic using a mass-balance trophic model suggests that predators are the dominant force controlling this food web.

TL;DR: The results indicate that even under similar environmental conditions and despite 24-h environmental cues, social synchronization can generate far more diverse behavioural rhythms than expected from studies of individuals in captivity.
