Plant tolerance to herbivory has been accepted as a mechanism of defense that can be
expressed jointly with resistance. Recent advances have partially validated previous …

There is growing interest in the interplay between ecological interactions among community
members and evolutionary processes. At all scales, from genetic variation within …

Genetic variation among plants can influence host choice and larval performance in insect
herbivores. Ploidy (cytotype) variation is a particularly dramatic form of plant genetic …

Abstract Host-plant resistance as a management tactic involves both the exploitation of
intraspecific variation in genetically based plant resistance to breed crop varieties that …

An increasing number of studies are being conducted to examine the density-or trait-
mediated indirect effects of large herbivores on phytophagous insects. However, these …

The consequences of interactions among genetic, ontogenetic, and environmental factors
for the quality of winter-dormant tissues as food for browsing herbivores is poorly …

The interaction of grape erineum mite (GEM), Colomerus vitis Pagenstecher (Acari:
Eriophyidae), with grape was investigated in the laboratory. We studied some plant …

Epichloë fungi, which are endophytic, live in symbiotic relationships with many cool-season
grasses. These symbiotic relationships change the vegetative, morphological, and …

Replanted Calligonum caput-medusae saplings in the Tarim River watershed face short-
term and frequent herbivory by goats, which can result in either growth inhibition or …

Tolerance, the degree to which plant fitness is affected by herbivory, is associated with
invasiveness and biological control of introduced plant species. It is important to know the …
