Effects of competitive pressure and habitat heterogeneity on niche partitioning between Arctic and boreal congeners
Abstract The rapidly changing climate in the Arctic is expected to have a major impact on the foraging ecology of seabirds, owing to changes in the distribution and abundance of their prey but also that of competitors (e.g. southerly species expanding their range into the Arctic). Species can respon...
