Dr. Sander's research is at the interface of community ecology, ecosystem ecology and macroecology, with a focus on how global change drivers and interspecific interactions influence the causes and consequences of biodiversity loss. Nate's research program takes advantage of environmental gradients and experimental manipulations arranged at multiple sites with the aim of forecasting the effects of environmental change on biodiversity. We do experiments on ants, plant-insect interactions, montane plant communities, and a whole variety of other taxa.
