The evolution of omnivory in heteropteran insects
Although omnivory is common and widespread across many animal taxa, the evolutionary origin of omnivory, the selective forces that promote or constrain omnivory, and the morphological, physiological, and behavioral hurdles ...
Host plants mediate omnivore-herbivore interactions and influence prey suppression
We conducted laboratory and field experiments to determine the effects of plant quality and prey abundance on the intensity of interactions involving an omnivorous insect, its two herbivorous prey, and their shared host ...
The ecological consequences of variation in plants and prey for an omnivorous insect
We conducted a series of laboratory and field experiments to determine the effects of variation in plant quality and prey species on the survival, dispersal, and population size of a common, omnivorous insect. We also ...
Effects of inbreeding in Mimulus guttatus on tolerance to herbivory in natural environments
Inbreeding, which is common in plants, may increase the vulnerability of. populations to natural enemies. Similarly, natural enemies may increase the expression of inbreeding depression in their hosts, resulting in altered ...
Plant defense theory provides insight into interactions involving inbred plants and insect herbivores
Inbreeding in the form of self-fertilization is widespread among plants and typically results in broad, detrimental changes in plant morphology and physiology. Phenotypic changes associated with inbreeding are likely to ...
Aphids alter the community-wide impact of fire ants
Positive species interactions have the potential to strongly influence the structure and dynamics of ecological communities, yet surprisingly few studies have documented their general importance. We tested the hypothesis ...
