Spring feeding by pink-footed geese reduces carbon stocks and sink strength in tundra ecosystems
Tundra ecosystems are widely recognized as precious areas and globally important carbon (C) sinks, yet our understanding of potential threats to these habitats and their large soil C store is limited. Land-use changes and conservation measures in temperate regions have led to a dramatic expansion of...
