Lake Malawi: A Treasure to Protect

Lake Malawi (also known as Lake Nyasa and Lake Niassa) doubles as a Rift Valley Lake and one of the seven African Great Lakes. Due to its unique biodiversity, it’s a great place to conduct limnological studies. Harvey Bootsma is a professor for the School of Freshwater Sciences at the University of Wisconsin-Milwaukee and has had an interest in limnology ever since he was a kid. Bootsma fondly recalls summer vacations to Georgian Bay, Ontario, “I probably spent as much time in the water as I did out of it.” He continues,”I remember telling myself ‘I’m going to get a job where I can stay here all the time.’” While Harvey didn’t end up working on Georgian Bay, he was offered a job working on Lake Malawi. He continued working there while completing his Ph.D.

Microbes and Human Health: Aquatic Microbial Communities May Hold Clues about How Deadly Pathogens Spread

Aquatic ecosystems are incredibly complex, with many different biotic and abiotic factors constantly interacting. Microbial communities are a key part of aquatic ecosystems, involved in the constant flow of energy and recycling of organic matter, according to Science Direct .  The true scope of microbial community impacts on aquatic ecosystems is still not entirely understood. Eric Benbow, a professor of community ecology at Michigan State University, is exploring how microbial communities and pathogens may be negatively impacting human health, and how a changing climate could worsen this problem.  How Do Pathogens Arise? Benbow, along with his students and colleagues, are studying a realm of community ecology that is still relatively unknown.
