Effect of grazing, trampling, and fecal deposition on vegetation and soil nutrients, Yukon Kuskokwim Delta Alaska, 2016
Herbivores play a key role in the turnover, gains and losses of nutrients in ecosystems. Because nutrients are often limiting, herbivores influence plant growth and chemistry, and their own resource supply. Herbivores typically affect their environment in three ways: they consume aboveground biomass...
