Common mudpuppies (Necturus maculosus) are large aquatic salamanders native to the Great Lakes region and were listed as threatened in Illinois in 2010.  I am funded by the Shedd Aquarium’s Daniel P. Haerther Center for Conservation and Research and am studying the natural history of mudpuppies. My specific objectives are to: (1) Assess individual movements, home range sizes, and habitat selection in response to seasonal changes in water temperatures; (2) Estimate population size, sex ratios, temperature dependent catch-per-unit-effort (CPUE), and seasonal diet shifts; and (3) Determine the physiological mechanisms underlying seasonal activity patterns, particularly increased activities during the coldest months. My study will help inform the conservation and management of mudpuppies throughout the Great Lakes region.

Claire Snyder

Graduate Student

Microchemical analysis of native fish passage through Brandon Road Lock and Dam. Claire is examining signatures of river residency across life histories in different species of native fish using the technique of microchemistry to determine whether fish have passed upstream through Brandon Road Lock and Dam, a structure outside of Chicago that has been proposed for modification to prevent upstream movement of aquatic invasive species. Native fish species movement may also be impacted and has not been studied to this point.

Nikki’s project focuses on manipulating rodent physiological function and will use an automated tracking network to conduct an extensive study of individual movements on the landscape. Additionally, the project will use experimental stable isotope enrichment to close the loop between bottom-up and top-down forces in the Chihuahuan desert ecosystem of central New Mexico.
