Responses of moist and dry arctic tundra to trampling and warmer temperatures
A two year study was conducted to evaluate the consequences of human trampling and elevated summer temperature on moist and dry arctic tundra. Field manipulations of trampling were applied in 0.75m2 plots and small, temporary greenhouses were erected to warm the soil and air temperatures. Plots were...
