TLDR
A mathematical analysis of the changes in plant relative growth rates necessary to increase aboveground production following grazing found that high grazing intensities are least likely to increase production and high grazing frequencies require greater responses than infrequent grazing events.Abstract:
A mathematical analysis of the changes in plant relative growth rates necessary to increase aboveground production following grazing was conducted. The equation derived gives an isoline where production of a grazed and ungrazed plant will be the same. The equation has four variables (mean shoot relative growth rate, change in relative growth rate after grazing, grazing intensity, and recovery time) and may be analyzed graphically in a number of ways.read more

Compensatory plant growth as a response to herbivory
TL;DR: Compensatory growth in plants subjected to herbivory may alleviate the potential deleterious effects of tissue damage, whether to vegetative or reproductive organs.

Does herbivory benefit plants? A review of the evidence
TL;DR: Although herbivores may benefit certain plants by reducing competition or removing senescent tissue, no convincing evidence supports the theory that herbivory benefits grazed plants.

TL;DR: Under the natural field conditions of this study, mammalian herbivores played a beneficial role in the survival and reproductive success of scarlet gilia.

The Ecology of Mutualism
TL;DR: In this paper, the authors define mutualism as "an interaction between species that is beneficial to both" since it has both historical priority (311) and general currency (general currency).

Grazing as an Optimization Process: Grass-Ungulate Relationships in the Serengeti
TL;DR: Experiments in Tanzania's Serengeti National Park showed that net above-ground primary productivity of grasslands was strongly regulated by grazing intensity in wet-season concentration areas of the large ungulate fauna, suggesting that conventional definitions of overgrazing may be inapplicable to these native plant-herbivore systems.

Phytophagous Insects as Regulators of Forest Primary Production
TL;DR: Although outbreaks (either local or extensive) do reduce plant production temporarily, they commonly occur in individual plants or in whole forest systems that are not particularly productive-that is, those which are under stress resulting from inadequate or excessive moisture, nutrient deficiencies, or pollution, or are senescent, having already passed their peak efficiencies in biomass production.
