Chelsea ColleyA study led by the University of Kentucky has been selected for funding by the National Science Foundation’s (NSF) “Biodiversity on a Changing Planet” program, an international, transdisciplinary effort that addresses major challenges related to climate change. The five-year project has been awarded nearly $2.5 million.
Led by Michael McGlue, associate professor in the Department of Earth and Environmental Sciences (EES) in the UK College of Arts and Sciences, the study seeks to understand how aquatic biodiversity in Africa’s Great Rift Valley is affected by climate change.
The award marks a major milestone for climate research at UK — something McGlue and EES faculty hope to see even more support for at Kentucky’s flagship, land-grant institution.
“Citizens of the Commonwealth have been touched by natural disasters (floods, landslides, drought) with increasing severity as the climate has changed, and the future remains uncertain,” McGlue said. “More research on climate change and its impacts are sorely needed at UK, including work that will help to build the resilience and preparedness of Kentucky communities.”
In this project, McGlue and his collaborators (which include scientists from the University of Toledo, University of Wyoming, University of Arizona, University of Connecticut, Indiana State University and Brown University) will study the food web in Lake Tanganyika, one of sub-Saharan Africa’s most prolific inland fisheries. While the lake is renowned for its biodiversity, the vast and ancient ecosystem is threatened by climate change in ways that are not currently well-understood.
“Climate and environmental changes present complex problems for life on Earth,” McGlue said. “In the tropics, climate change threatens the healthy function of freshwater fisheries, and places poor communities at risk of losing an important food source.”
The project, titled “The impact of climate change on functional biodiversity across spatiotemporal scales at Lake Tanganyika, Africa,” will assess several different scenarios of climate change and its effects on the lake’s ecosystems. Using high-resolution geological records, fossils and genetic tools, the team will set up a series of experiments to track variability in the lake’s biodiversity across thousands of years. The results will show how the food web responds to changes in temperature and precipitation, with potential for predicting changes in biodiversity amidst severe climatic uncertainty in large tropical lakes.
