Since 2008, Dr. Frimpong and his team of students and technicians have been conducting field studies in the middle New River basin in Virginia as a model system for studying individual species, fish communities, and human mediated changes in species distributions. It is emerging from these studies that nest association interactions of a mutualistic nature may be one of the key processes by which the cyprinid and centrarchid populations and the community are adapting and persisting in this basin in the face of historical agriculture and current urbanization. Nest association does not only explain persistence and dispersal of species, but also substantially explains the common macroecological phenomenon of rarity and commonness in community organization. The overarching emerging question in this project is how the biotic (e.g., predator abundances) and abiotic (e.g., spawning substrate availability) contexts drive the evolution of the modes of reproduction, strength of nest association, and its fitness consequences for participating species. The lab is now using field experimental studies to investigate the phenomenon of nest association and context dependency, with funding from the National Science Foundation (NSF).
Current Research Projects:
Testing the effect of context on a nest association mutualism of stream fishes in a comparative- advantage biological market framework. [Funded by NSF, Division of Environmental Biology, Population and Community Ecology cluster]
Modeling how traits mediate fish vulnerabilities to specific habitat alterations. [Funded by US Geological Survey, Biological Informatics Program]
Enhancing the profitability of small aquaculture operations in Ghana, Kenya, and Tanzania through improved resource management and environmental Best Management Practices (BMPs). [Funded by USAID AquaFish Collaborative Research Support Program (CRSP) through Oregon State University subcontract and collaboration with Purdue University]
Development of assessment tools for evaluating stream and watershed responses to climate change along thermal gradients. [Collaboration with P. L. Angermeier; funded by USDA Forest Service]
