In this study, acoustic ecology, the analysis of soundscapes -- composed of geophony, biophony, and anthrophony -- is applied as a potential measurement of ecosystem health. Recordings were taken from four locations in the greater Chicago area. By combining traditional ecological assessments including soil analysis, worm density surveys, and vegetation surveys, and correlating the results with acoustic data we highlight the value of soundscape analysis and suggest lines of future inquiry.

Body Shape Divergence In Invasive Round Goby, Cat Collins

DePaul Discoveries

The round goby, Neogobius melanostomus, originally native to the Black and Caspian seas, was introduced into the Great Lakes via ballast water in the 1990’s. Since then, the species has spread to all of the Great Lakes, thriving in the Lake Michigan region and spreading to surrounding bays and rivers. Invasive species are considered to have a high evolutionary potential. Differences in environmental conditions between native and introduced ranges stimulate adaptive evolution. Multiple introductions of an exotic species can result in separate instances of founder effects, further increasing the chance of evolutionary change. A total of 267 round goby specimens …
