Research Interests

Impact of an invasive freshwater clam (Corbicula fluminae) on an urban stream, Buck Creek, MI: Research combines laboratory and in-stream experiments to evaluate the effect of different densities of Corbicula on interstitial water chemistry, macroinvertebrates, and benthic algae. (1 graduate student, ongoing)

Development of a habitat suitability model for juvenile lake sturgeon (Acipenser fulvescens) in the lower Grand River, MI: Using existing geomorphological data, a habitat suitability model will be developed and tested in the lower Grand River. In addition, we will attempt to capture and tag juvenile sturgeon for telemetry tracking to evaluate movement patterns and habitat preference. (1 graduate student, ongoing)

Management and conservation of burbot (Lota lota):  Burbot are an understudied fish, considered to be keystone predators in lakes and streams. Ongoing research will explore their movement patterns and identify habitat preferences and home-range distribution. (1 graduate student, completed 2022)

Aquatic macroinvertebrates as biological indicators in the Grand River, MI: Biological indicators, such as aquatic macroinvertebrates, are used to evaluate aquatic ecosystem integrity. A comparison of 25 sites in the Grand River allows us to (i) establish baseline conditions in the downtown reach of Grand River, Grand Rapids, where restoration of the river is slated to occur in beginning in the summer of 2021, and (ii) apply trait-based metrics that consider functional as well as structural integrity. (1 graduate student, 1 undergraduate student, completed 2022)

Freshwater mussel conservation: how do we do better at translocation:  Freshwater mussels are one of the most imperiled invertebrate animals on the planet and translocation is an important conservation tool.  But we know relatively little about the environmental, physical, chemical, and biological attributes influencing successful outcomes.  (1 graduate student, completed 2021)

Niche partitioning between Brook Trout (Salvelinus fontinalis) and Brown Trout (Salmo trutta):  Exploration of the behavioral and feeding interactions between these species in a small, headwater stream.  Experimental manipulations are planned.  (1 graduate student, ongoing)

 Ecology of River Redhorse (Moxostoma carinatum):  Graduate student research will focus on habitat selection and eDNA sampling to explore distribution of this state threatened species. (1 graduate student, ongoing)

 Ecology of Neotropical cloud forest streams, Ecuador:  A study-abroad class participated in research to establish baseline biological conditions using macroinvertebrate, chemical and physical characteristics in 3 river systems located within the Pichincha Province of Ecuador—a cloud forest biome. Graduate student research has continued with an assessment of the riparian amphibian population and a food web study using stable isotopes focusing on several species of glass frogs and upcoming research will explore the potential impacts of rainbow trout farming on the aquatic ecosystems within the cloud forest. (2 graduate & multiple undergraduate students, ongoing)

Ecology and management of freshwater dune wetlands:  Graduate research will focus on the relationship between interdunal wetland characteristics such as size, hydroperiod, and biogeographic proximity to other wetlands, and biodiversity with an emphasis on amphibian community structure. (1 graduate & 2 undergraduate students, ongoing)

Establishing base-line biophysical condition in the Coldwater River, MI, post riparian removal and dredging:
