An Indiana University professor will discuss "The Power of Plankton" and "the foundations of a healthy watershed through the lens of microbiota" in downtown Valparaiso Monday.
Sarah Powers, an adjunct instructor at IU's School of Environmental and Public Affairs School, will give a talk sponsored by the Valpo Chain of Lakes Watershed Group at 7 p.m. Monday in the Chambers Room of the Porter County Administration Building, 155 Indiana Ave.
She'll discuss what keystone species like plankton reveal about the lakes in the talk, which is free and open to the public.
"Sarah Powers will speak about plankton in lakes and provide specific examples of plankton data from the lakes in the watershed," organizers said in a news release.
"Additionally, she will explain the history and information that has been gathered by the Indiana Clean Lakes Program on lakes in the watershed and explain ways citizens can be involved in monitoring lakes.
"Plankton are the critical and fascinating microscopic floating plants and animals at the foundation of our lake’s ecosystem which form the beginning of the food chain including larger plants, insects, reptiles, fish, birds, and ultimately mammals, including the human population of Porter County."
Powers, who teaches environmental science classes at IU and works as the lab manager for the Indiana Clean Lakes Program, also will answer questions during a Q&A session at Greek's Pizza next door after the presentation is concluded.
