Change in Arctic climate has direct effects on the growth and productivity of tundra
vegetation and indirect effects through climate induced changes in herbivore intensity.
Herbivores have huge potential to modify both species composition and biomass through
selective grazing, intensity of grazing and trampling, and nutrient turnover through feces
deposition. When considering future scenarios of climate impacts on Arctic tundra it is
therefore important to include the knock-on effects of changes in grazing, caused by …
