The Importance of Incorporating Landscape Change for Predictions of Climate-Induced Plant Phenological Shifts
Warming in the high Arctic is occurring at the fastest rate on the planet, raising concerns over how this global change driver will influence plant community composition, the timing of vegetation phenological events, and the wildlife that rely on them. In this region, as much as 50% of near-surface...
