The objective of this research is to quantify differences molecular level genetic damage to bullhead catfish in the heavily contaminated Lake George reservoir versus levels of damage in bullhead catfish from the virtually uncontaminated Jasper Pulaski reservoir using the alkaline DNA unwinding method.
- Quantify contaminant levels in salmon and stream-resident fish at three sites at the southern end of Lake Michigan
Our overall goal is to provide quantitative descriptions of species characteristics that increase the probability of successful invasion.
Determination of the effects of culture temperature on growth, survival and biochemical composition of largemouth bass (Micropterus salmoides)
To evaluate the effect of culture temperature on growth, survival, and body composition of largemouth bass.
Development of a Biological Indicator of Exposure to PAHs in Fishes of the Grant Calumet River System
The objective of this project is to develop a rapid, sensitive assay for detecting the exposure of fishes to carcinogenic polycyclic aromatic hydrocarbons (PAHs) in contaminated aquatic ecosystems.
Drivers of microbial food web structure and function: Bottom-up and topdown controls across Lake Michigan
The researchers used molecular tools to characterize microbial communities in the changing biogeochemistry of Lake Michigan (2012-2015) and across the Laurentian Great Lakes.
Evaluating environmental DNA detection alongside standard fish sampling in Great Lakes coastal wetland monitoring
- Develop and apply eDNA sampling methods for detecting fish species and measuring eDNA concentration in these large, complex habitats
- Compare results between fish capture methods and eDNA methods
- Count zooplankton already collected from Green Bay
- Contribute to a lakewide understanding of mechanisms limiting recruitment of yellow perch
- Provide information useful to fisheries managers
Food webs in the 21st century: exploration of new enabling technologies to understand and predict changes in aquatic food webs and impacts of ecosystems
- Explore application of a new enabling technology to aquatic food web dynamics
- Assess whether organisms within trophic levels have unique chemical/nutrient compositions
