Global Change Biogeography

Earth's ecosystems globally have been increasingly altered by a variety of environmental change factors that include climate warming, drought, sea-level rise, ocean acidification, eutrophication, pollution, species invasions, overharvesting, etc. While mounting individual site-scale studies have shown the impacts of global change on ecosystems and their underlying mechanisms, we lack an understanding of patterns in and mechanisms underlying their variations across spatial scales that include site-to-site differences (spatial extent) and dependency of investigation size (grain size).


In my research, I try to incorporate a spatial, biogeographic perspective into understanding the patterns in and mechanisms underlying variations in the impact of environmental change on ecosystems, which may be called Global Change Biogeography. My recent works include: how the impact of nutrient enrichment and top-down control in coastal wetlands vary geographically across latitude and climate.
