Studies of herbivory and vegetation change in Karoo shrublands
… and introduced herbivores and the effects of herbivory, competition and rainfall on plant reproduction and recruitment. The results of these investigations are presented as 14 papers. The first three papers interpret plant morphology and biogeography to provide information on past spatial and …

Constraints on plant resistance and tolerance trade-offs
Plant tissue loss due to herbivory is an important selective force for shaping plant phenotypes (Marquis 1992). Therefore, plants have evolved a variety of mechanisms to mitigate the negative effects of herbivory. Much of what we have learned, to date, on plant responses to their enemies …

The Interaction of Arvicoline Rodents and Sheep in Norwegian Alpine Rangeland
… effect of fertilization but little effect of mammalian herbivory on plant quality, perhaps because of the relatively low overall densities of herbivores at my study site. I also investigated the influence of low to moderate densities of sheep on density and choice of food by field voles. To do …

Overcompensation of Ipomopsis aggregata following ungulate herbivory: getting to the root of it
… demonstrating enhanced fitness following herbivory, i.e., plants overcompensate. The mechanistic underpinnings of overcompensation, however, are unclear. For example, it has been assumed that plants growing in high resource conditions are best able to compensate for herbivory. However, …

Managing herbivory over space and time: consequences for vegetation and cattle responses in African rangelands
Mammalian herbivory is integral to determining vegetation structure, composition and ecosystem function in African rangelands, however the extent to which managing the movement of herbivores, specifically livestock, over time and space can sustain functioning and productive rangelands remains …

Functional genomics of plant compensatory responses
… flower, fruit, and seed production following herbivory). Specifically, studies by Paige and Whitham (1987) showed that when mule deer and elk removed 95% or more of the aboveground biomass of the monocarpic biennial scarlet gilia, Ipomopsis aggregata, the lifetime seed production, seed …
