The nitrogen window for arctic herbivores: plant phenology and protein gain of migratory caribou (Rangifer tarandus)
Abstract Terrestrial plants are often limited by nitrogen (N) in arctic systems, but constraints of N supply on herbivores are typically considered secondary to those of energy. We tested the hypothesis that forage N is more limiting than energy for arctic caribou by collecting key forages (three sp...
