Technical Abstract: The ability to predict the consequences of global change is predicated on our understanding of controls of energy and material flows through ecosystems. A significant gap in that understanding is in the interaction belowground and at the soil-litter interface. The effects of CO2-enriched leaf litter on soil fungi, bacteria, and micro arthropods have begun receiving attention in the past decade; however, macro arthropod detritivores have been largely neglected. Even less attention has been given to the effects of litter quality on detritivores-predator interactions. This project is investigating arthropod responses to reduced dietary quality (litter or prey) which include reduced fitness, increased consumption, and alterations of dietary preferences, all of which would impact nutrient cycling and carbon flow through forest systems.
