What are the consequences of climate change on biodiversity and ecosystem processes? Using open-top warming chambers, we are manipulating climate experimentally to understand how climate change affects insect communities and the processes they mediate. Built in 2009 at both Duke Forest in North Carolina and Harvard Forest in Massachusetts, the warming chambers consist of 12 open-top warming chambers that are pumped with warm air to simulate predicted environmental changes. It is one of the largest, most robust warming experiments in the world. We monitor population dynamics, species composition, phenology and behavior of ants and other arthropods occupying these experimental chambers. This experiment is an ongoing long-term ecological study that provides opportunities for collaborations across a broad spectrum of ecologists, including those studying biogeochemical, microbial and plant responses to warming.
