The Herbivory Uncertainty Principle: Visiting Plants Can Alter Herbivory
Ecology, 2001In 1927, Werner Heisenberg proposed that there are fundamental limitations to the study of subatomic particles, as the act of measuring them affects their behavior. Here we show that experimenter-induced uncertainty also applies in plant ecology, with potentially dramatic consequences for field biologists.

Beaver herbivory on aquatic plants
Oecologia, 2006Herbivores have strong impacts on marine and terrestrial plant communities, but their impact is less well studied in benthic freshwater systems. For example, North American beavers (Castor canadensis) eat both woody and non-woody plants and focus almost exclusively on the latter in summer months, yet their impacts on non-woody plants are generally ...

Terrestrial plant tolerance to herbivory
Trends in Ecology & Evolution, 1994Damage to plants by herbivores is ubiquitous and sometimes severe. Tolerance is the capacity of a plant to maintain its fitness through growth and reproduction after sustaining herbivore damage. Recent physiological and ecological work indicates that tolerance mechanisms are numerous and varied.

In Chapter 5, the light climate within the rainforest was assessed within the vicinity of a leaf-cutting ant colony. These measurements highlighted the enormously variable light conditions both vertically through the canopy and near the forest floor. Since the cutting of leaves by ants affects canopy structure and subsequent light penetration (Plates ...

Herbivory simulations in ecological research
Trends in Ecology & Evolution, 1990Because of the experimental advantages that they offer, mechanical simulations of grazing are more commonly used than true herbivory in ecological studies of the impact of herbivory on plants. However, few studies have explicitly compared plant responses to herbivory and to mechanical simulations.

There is a growing body of evidence for a wide range of spider families that they use nectar as supplementary resource, while pollen feeding in web-building spiders has been studied in the laboratory including a few species only. Considering that many spiders use nectar provided by plants, we can assume a greater potential for mutualistic interactions ...
