To achieve a coherent evolutionary theory, it is necessary to account for the effects of the
environment on the process of development. Phenotypic plasticity is the change in the …

Over the past 40 years there has been an extraordinary effort to understand the relationships
of plant-feeding insects and their hosts. Anyone who is studying such problems knows the …

The idea that traits that adapt a population to one habitat or host are deleterious in other
habitats or on other hosts is central to most theories for the evolution of ecological …

This research assessed (1) the relationship between defoliation and phenolic chemistry of
red oak trees, and (2) the relationship between food quality, measured in terms of oak …

The dazzling variation in plant chemistry is a primary mediator of trophic interactions,
including herbivory, predation, parasitism, and disease. At the same time, such interactions …

We selected on phenotypic plasticity of thorax size in response to temperature in Drosophila
melanogaster using a family selection scheme. The results were compared to those of lines …

Trade-offs in performance on different hosts are thought to promote the evolution of host
specificity by blocking host shifts. Yet, in contrast, most experiments using phytophagous …

The nutritional environment of the parental generation of the polyphagous gypsy moth,
Lymantria dispar, can significantly influence the growth and reproductive potential of the …

Gene frequencies in large populations are determined by a balance between selection and
gene flow between neighborhoods of different selection regimes. This balance is affected by …

Survival and body composition of starving gypsy moth larvae initially reared on aspen
foliage or artificial diet differeing in nitrogen (N) and carbohydrate concentration were …
