I (Dr. Jim Garvey) am seeking up to three fully funded, highly motivated and innovative graduate students (M.Sc. and Ph.D.) to join my lab in the Center for Fisheries, Aquaculture, and Aquatic Sciences in the School of Biological Sciences at SIU. Start dates are flexible from Fall 2022 through Summer 2023. Projects can vary focusingContinue reading “Graduate Assistantships in Fish Ecology”

Responsibilities: Help lead a funded, multi-year project to develop a generalized, user-friendly individual (agent)-based model of sportfish growth for fisheries management in lakes and streams of the central/midwestern US. Collaborate with ecologists at Southern Illinois University (SIU), a doctoral research university in the Shawnee Hills region at the intersection of several unique ecoregions. Use outreachContinue reading “Post Docs and PhD Assistantships in Apex Fish Modeling”

If you have data that look like those above, then you may have a threshold relationship where the changes in the dependent variable (y) are due to some functional shift caused by the independent variable (x). In 1998, a paper “From Star Charts to Stoneflies: Detecting Bivariate Patterns in Continuous Bivariate Data” was published inContinue reading “A Threshold Test In Ecology”

Things eat things. My colleague, Dr. Matt Whiles and I recently wrote a text called Trophic Ecology, which is the starting point for this site. What is Trophic Ecology? Trophic Ecology is a branch of ecology that studies how energy is transferred among organisms within ecosystems. Sometimes things just ooze food, like plant sap beingContinue reading “Predation Is Cool”
