Understanding how climate change impacts natural systems requires investigations of the effects of environmental variation on vulnerable species and documentation of how populations respond to change. The willow beetle Chrysomela aeneicollis is ideal . . .

The food web of Symmorphus cristatus wasps, leaf beetle larvae (Coleoptera: Chrysomelidae) and willow (Salix spp.) trees is a model system for studying the chemical ecology of plant, herbivore and predator interactions. However, little is known about . . .

Invasive species can experience strong selection in their new environments. Some populations of invasive Spartina spp. cordgrass in Pacific estuaries have been separated from the specialist planthopper Prokelisia marginata for many generations while v . . .

The heat shock response is a critical mechanism by which organisms buffer effects of variable and unpredictable environmental temperatures. Upregulation of heat shock proteins (Hsps) increases survival after exposure to stressful conditions in nature, . . .

Declining predator diversity may drastically affect the biomass and productivity of herbivores and plants. Understanding how changes in predator diversity can propagate through food webs to alter ecosystem function is one of the most challenging ecolo . . .

Human-caused changes in land use and land cover have dramatically altered ecosystems worldwide and may facilitate the spread of infectious diseases. To address this issue, we examined the influence of land-cover changes between 1942 and 2000 on the es . . .
