Emi Tucker, PhD Student

firefox During my undergraduate degree at Anderson University in Indiana, I studied the interaction between culture, ethics, and environmental stewardship. I took a few science classes just for fun during my senior year, and I quickly fell in love with scientific research and biology. After graduating with my B.A. in global studies, I did a post-baccalaureate science program at the University of Rochester before going to North Carolina State University for my master's degree in physiology. At NCSU, I studied the role of macrophages in luteolysis in the pig. It was not very "fishy," but this research gave me a solid biochemical and molecular background that I still use today. While I was getting my M.S., I volunteered with the vet school's Turtle Rescue Team, which sparked my interest and passion for aquatic animals and their habitats.

Currently, I am working on my PhD with Dr. Cory Suski (NRES) and Dr. Romana Nowak (Animal Science). My project focuses on using fish physiology and behavior to inform solutions to three human-induced problems: invasive species, climate change, and pollution. For example, I am investigating how invasive Asian carp at different points along the Illinois River differ in reproductive maturity and function using a variety of biochemical and histological techniques. I am also interested in how social interactions affect extreme environment avoidance (i.e. high CO2), and how environmental toxicants affect fish physiology and behavior.

When I am not working, I enjoy hiking with my mini dachshund, fishing, and watching documentaries that are narrated by David Attenborough.

Toniann Keiling, MS Student

firefox I majored in Marine and Environmental Biology and Policy at my undergraduate institution, Monmouth University in New Jersey. I completed an Honors thesis, which was later published, on carbon sequestration in mangrove sediments, but I knew that still wasn't my life-long field of study. However, after taking Ichthyology, I knew I wanted to study bony fish. After graduation, I interned at the American Littoral Society Marine Fish Tagging Program, which expanded my knowledge about anglers and how fishing affects communities. I was also a Flats Ecology and Conservation intern at the Cape Eleuthera Institute in The Bahamas, where I learned about the importance of bonefish in mangrove ecosystems. For a while after, I was an environmental activist at Citizens Campaign for the Environment on Long Island, New York, and later, I landed a fisheries technician job for the Atlantic States Marine Fisheries Commission, where I interviewed anglers and collected data on their catch.

After all of those experiences, I ended up in Cory's lab as a Master's student in Natural Resources and Environmental Science. I am currently working on a project which explores largemouth bass vulnerability to angling based on behavior types and food availability. My specific question is, are bold or shy fish more likely to be caught in pond systems with and without the presence of forage species (fathead minnows in this case)?

Outside of the lab, I enjoy exploring prairies, reading under trees, and watching competitive cheerleading competitions.

Michael Louison, PhD Student

firefox I earned my Bachelor's degree from Ripon College in Ripon, Wisconsin in 2007 with a major in biology and a minor in educational studies. After three years of teaching high school science in Central Wisconsin I returned to graduate school and obtained my Master's degree in biology from the University of Wisconsin at Oshkosh in 2013. My M.S. work focused on habitat choice by young-of-the-year salmonids, particularly brown trout. More specifically I examined the suitability of very small first-order stream habitats for YOY trout, and what hydrological and habitat features were associated with greater or lesser densities throughout the year.

My current work here at the University of Illinois centers on the factors that predispose a fish to vulnerability to angling. I am currently am conducting a series of experiments aimed at determining correlates of angling vulnerability, with a focus on inter-individual differences in behavior and physiology (i.e. "personalities", which believe it or not individual fish have been shown to have!). I also am utilizing molecular and genetic methods in an effort to discover gene candidates which may predispose a fish to greater inherent catchability. The upshot of this research broadly is to determine the traits that may be under selective pressure in recreational fish species. Anglers in effect are a predator of game fish species and intense angling has the potential to evolutionarily change populations by removing fish with particular "catchable" traits. It is important that those traits are identified, since the loss of fish with those phenotypes from a population may have overall fitness consequences for that population.

In my spare time I enjoy kayaking around at a leisurely pace in small lakes and streams and dipping a line in the water. I am an avid football fan and will never miss a Green Bay Packers game, even in unfriendly territory here in Illinois.
