Predictors of invertebrate biomass and rate of advancement of invertebrate phenology across eight sites in the North American Arctic
Average annual temperatures in the Arctic increased by 2–3 °C during the second half of the twentieth century. Because shorebirds initiate northward migration to Arctic nesting sites based on cues at distant wintering grounds, climate-driven changes in the phenology of Arctic invertebrates may lead...

Average annual temperatures in the Arctic increased by 2–3 °C during the second half of the twentieth century.
