Abstract
Many laboratory and field studies suggest that heavy grazing decreases plant productivity, whereas light grazing may promote increases in comparison with ungrazed controls. A theoretical and computer-simulation model shows how biomass and nutrient interactions can give rise to these grazing responses. The recycling rates of limiting nutrients can be regulated nonlinearly by the grazer. This provides a plausible mechanism for explaining changes in primary productivity that are consistent with empirical data.
