Onset HOBO RX3000 Remote Soil Monitoring Station
The Onset HOBO RX3000 Remote Monitoring Station is an environmental monitoring system that continuously logs data from compatible sensors that measure soil moisture, water level, temperature and various weather parameters. With numerous options for remote monitoring systems, Onset provides a Build-a-system configurator to help with ordering a system fit for any project’s needs. The configurator easily guides the user through the process of selecting different types of communication, power, sensor and other site-specific requirement selections when building their ideal system. 
 
 The RX3000 ships with mounting plates and hardware, rubber cable channels, rubber plugs, grease, grounding wire and U-bolts.

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.

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.
