David B Bunnell, PhD
David "Bo" Bunnell is a Research Fishery Biologist based in Ann Arbor, MI.
I am a Research Fishery Biologist at the Great Lakes Science Center, and Associate Adjunct Professor at the University of Michigan. I am the Principal Investigator (PI) for multiple projects that study community and ecosystem-level processes within the Great Lakes and at the global scale. In short, my research seeks to understand the ecological factors (e.g., resources, climate, predation) that can explain or predict fish biomass, consistent with an ecosystem-based approach to fisheries science and management.

Lake Michigan offshore ecosystem structure and food web changes from 1987 to 2008
Ecosystems undergo dynamic changes owing to species invasions, fisheries management decisions, landscape modifications, and nutrient inputs. At Lake Michigan, new invaders (e.g., dreissenid mussels (Dreissena spp.), spiny water flea (Bythotrephes longimanus), round goby (Neogobius melanostomus)) have proliferated and altered energy transfer pathways, while nutrient concentrations and stocking rateAuthorsMark W. Rogers, David B. Bunnell, Charles P. Madenjian, David M. WarnerDiet of Mysis diluviana reveals seasonal patterns of omnivory and consumption of invasive species in offshore Lake Michigan
Recent changes in Lake Michigan’s lower trophic levels were hypothesized to have influenced the diet of omnivorous Mysis diluviana. In this study, the stomach contents of Mysis were examined from juvenile and adults collected monthly (April–October) from a 110-m bottom depth site to describe their seasonal diet in LakeMichigan during 2010. Diatoms were the most common prey item ingested, followedAuthorsBrian P. O'Malley, David B. BunnellChanging ecosystem dynamics in the Laurentian Great Lakes: Bottom-up and top-down regulation
Understanding the relative importance of top-down and bottom-up regulation of ecosystem structure is a fundamental ecological question, with implications for fisheries and water-quality management. For the Laurentian Great Lakes, where, since the early 1970s, nutrient inputs have been reduced, whereas top-predator biomass has increased, we describe trends across multiple trophic levels and exploreAuthorsDavid B.

WeidelGastric evacuation rate, index of fullness, and daily ration of Lake Michigan slimy sculpin (Cottus cognatus) and deepwater sculpin (Myoxocephalus thompsonii)
Accurate estimates of fish consumption are required to understand trophic interactions and facilitate ecosystem-based fishery management. Despite their importance within the food-web, no method currently exists to estimate daily consumption for Great Lakes slimy (Cottus cognatus) and deepwater sculpin (Myoxocephalus thompsonii). We conducted experiments to estimate gastric evacuation (GEVAC) and cAuthorsJustin G. Mychek-Londer, David B. Bunnell - News
