We are very grateful for UTC AEROSPACE SYSTEMS for allowing us to host this look at wonder and awe in nature. We feel the series represents a diverse perspective on a variety of topics on the subject. We hope to see you out here.


Presented by Jeremy Tiemann, Aquatic Zoologist Illinois Natural History Survey

.North American freshwater mussels have undergone drastic decline during the past century, and subsequently have become one of the most imperiled groups of animals.  Of the approximate 350 species of freshwater mussels native to North America, nearly three-quarters are extinct, federally–listed as endangered or threatened, or are in need of conservation status.  The first project is Steps Taken During the Reintroduction of Two Federally-Endangered Mussels, which will reflect how a salvage project in Pennsylvania has provided an opportunity for the translocation of two federally-endangered freshwater mussels back into Illinois.  The second project is Effects of Lowhead Dams on Freshwater Mussels, which will discuss the two upcoming dam removals occurring in the basin and how these dams appear to have affected the freshwater mussel assemblage.


Jeremy has been a Field Biologist / Aquatic Zoologist specializing in stream ecology with the Illinois Natural History Survey since 2002.  As a farm kid growing up in northeastern Kansas, he traipsed through streams in his free time chasing various critters.  This passion led him to a Bachelor of Science in Biology from the University of Kansas in 1998 and a Master of Science in Biological Sciences from Emporia State University in 2002. 

His professional research interests include stream ecology and life history of non-game fishes and freshwater mollusks.
