Low herbivore populations and the question of cattle lifting by tigers needs to be researched, and a detailed analysis of the prey base is essential.

Many of the park's large herbivore populations were greatly reduced by years of war and poaching.

The strongest evidence for anti-herbivore benefits of fungal endophytes come from studies of herbivore populations being extirpated when allowed to feed only on infected plants.

Overfishing higher trophic levels that naturally regulate herbivore populations is also recognized as an important stressor in kelp forests.

The park and the Athi-Kapiti Plains are linked by the migrations of wild herbivore populations.

Boom-bust cycles in herbivore populations change the nature of the vegetative environment, with consequent climatic impacts on relative humidity and continentality.

It is unable to explain why large herbivore populations were not regulated by surviving carnivores such as grizzly bears, wolves, pumas, and jaguars whose populations would have increased rapidly in response to the loss of competitors.

The "world is green", they reasoned, despite the insatiable appetite and enormous diversity of herbivores, because herbivore populations are held in check by their own natural enemies-predators, parasitoids, parasites, and pathogens.

Overfishing of herbivore populations can cause algal growths on reefs.

Landscape-level conservation of wilderness habitat and recovery of wild herbivore populations as prey base for the tiger will be required.
