Climate and environmental drivers of berry productivity from the forest-tundra ecotone to the high Arctic in Canada
Abstract Berry shrubs are found across the circumpolar North where they are an important source of food for people and animals. However, the environmental controls on berry productivity in these regions is poorly understood. This study presents the results of an ongoing berry productivity monitoring...
