Aquatic Ecology, Evolution, and Organismal Biology

Research in this lab addresses spatial and temporal population, community, and ecosystem level patterns. The primary subjects utilized in this lab include North American freshwater fish, gastropods, insects, and crayfish. Some of the techniques employed in the lab include geometric morphometrics, ecological niche models, phylogenetic comparative methods, geographic information systems, stable isotopes, and multi-metric biological and habitat assessment procedures. Lab research has facilitated collaborations with numerous state and academic institutions including Illinois Natural Survey, Ball State University, College of Charleston, Illinois State University, and management agencies across the Midwest. Lab work is funded through internal, local, state, and federal research monies.


Some of the Current Projects in the Lab Include:

- Freshwater fish surveys and environmental assessments of Grand Lake St. Marys and Tributaries

- What drives morphological variation in aquatic organisms?

- Macroevolutionary patterns in freshwater fish abundance. Co-PI - J. Doll

- Long term growth variation in freshwater drum: can it be explained using long term variation in flow regime? Co-PIs - J. Doll, M. Allen, M. Pyron

- Does morphological niche covary with ecological niche across freshwater gastropods? Co-PIs - B. Ross, M. Pyron

- What is the role of heritability in determining freshwater gastropod shell morphology? Co-PI - R. Dillon

- Evolution of early vertebrate dentition in Devonian Cladoselachidae. Co-PI - C. Ciampaglion (WSU) - Find out more.

- Role of sperm competition in the evolution of mating systems in North American sunfish and black basses. Co-PIs - J. Bagley & M. Pyron
