Ecosystems Under Threat

As the built environment continues to encroach on the natural, delicate ecosystems come under ever-urgent threats. Researchers at the University of Michigan are taking a focused, multifaceted lens to a global problem — assessing human-exacerbated “dead zones” in the Gulf of Mexico and Lake Erie, noting the resilience of invasive species enabled by human activity, and analyzing the impacts of our changing climate on the health and behavior of different species and ecosystems. Experts at the School for the Environment and Sustainability (SEAS), the LSA Department of Ecology and Evolutionary Biology, and the Graham Sustainability Institute are shedding a light on how humans have disrupted ecosystems, and how they can better protect and restore them in the future.

New research shows that some high-latitude North American forests, like the Alaskan forest shown here, are beginning to show increased browning, suggesting that they may not continue to absorb more carbon as temperatures continue to rise.
