Shrub expansion in tundra ecosystems: dynamics, impacts and research priorities

Abstract:

Recent research using repeat photography, long-term ecological monitoring and dendrochronology has documented shrub expansion in arctic, high-latitude and alpine tundra ecosystems. Here, we (1)synthesize these findings, (2)present a conceptual framework that identifies mechanisms and constraints on shrub increase, (3)explore causes, feedbacks and implications of the increased shrub cover in tundra ecosystems, and (4)address potential lines of investigation for future research. Satellite obser...
