The Office of the Vice President for Research is pleased to host the next Water@Wayne seminar on Thursday, February 23, 2017 from 2:30 to 3:30 p.m. in the Bernath Auditorium located in the David Adamany Undergraduate Library. The seminar is free and open to the public; registration is requested.
The Water@Wayne Seminar Series presents: "Fish in the city: the roles of habitat use and foraging in urban aquatic ecosystems" with Scott Colborne, University of Windsor. Scott is a post-doctoral fellow at the University of Windsor's Great Lakes Institute for Environmental Research (GLIER) where he currently focuses on understanding how fish species interact with each other in the Detroit River by examining both spatial distributions and food web structure. His current research at GLIER is focused on how urbanization is impacting habitat use and foraging ecology of native fishes in the Detroit River using a combination of stable isotope analysis (food web structure) and acoustic telemetry (habitat use).
Aquatic ecosystems provide sustenance, recreational activity, and economic products for humans around the world, but urbanization has increased pressure on aquatic ecosystems due to the concentration of humans around sources of freshwater. Up to 90% of all humans live within 10 km of a surface freshwater source and this close association with water has a number of impacts on aquatic ecosystems, including physical alteration (e.g. hardened shorelines, dredging), introduction of contaminants (e.g. PCBs), and the establishment of invasive species (e.g. zebra mussels, round goby). Growing efforts to manage and restore aquatic habitats around urban centres are increasingly focused on using an ecosystem services approach that balances the environment with human needs, but this approach requires a thorough understanding of the ecology of species in these environments. Early restoration efforts have been criticized for a lack of ecological-based decision making, identifying habitat use and foraging dynamics as two of the fundamental components to restoring productive ecosystems. Using the Laurentian Great Lakes, and the Detroit River in particular, as a study system he will discuss the roles of spatial and foraging ecology in efforts to restore ecosystems impacted by urbanization.
A short reception will be immediately after the seminar.
