Cover illustration: The inset cover image is a thermal signature of Populus tremuloides attacked by a galling arthropod (Cecidomyiidae: Harmandia sp.). Galling insects commandeer plant developmental processes and alter transpiration as an example of one way arthropod herbivory indirectly suppresses photosynthesis. Four trends for how different arthropod guilds and induced defences interact with the component processes of photosynthesis at physiological and genetic levels are discussed by Nabity et al. (pp. 655-663).
