Current Research:

I am currently engaged in two primary areas of research: stream fish and freshwater mussel ecology and conservation of aquatic organisms.This research encompasses spatial scales ranging from individual habitat units such as pools to entire watersheds to drainage basins.The research is located in the Interior Highlands, Southern Appalachians, and southern bottomland streams, wetlands, and associated riparian systems.Work on stream fish ecology includes studies of local colonization and extinction dynamics in relation to environmental variability, effects of road crossings on fish movement, recovery of stream fishes after disturbance, and the structure, stability, habitat, interrelationships, and trophic dynamics of warmwater fish communities.Freshwater mussel ecological research is focused on determining reproductive requisites (e.g., seasonality, fish-hosts, and modes of propagule dissemination), associating local and large-scale physical influences on mussel community structure, and development methods for efficient, repeatable monitoring and inventory.Conservation research includes assessments of aquatic biodiversity (e.g., Interior Highlands, Daniel Boone National Forest, and Region 8) and examining association of biological and landscape-scale factors with imperilment of aquatic organisms.In the near future, I will initiate a study examining the use indicators of ecosystem function (e.g., nutrient spiraling) to assess watershed stress in forested ecosystems.

Collaborative Research:

Within the umbrella of Cross-cutting Themes, I see several opportunities for collaboration. I am interested in large-scale assessments and modeling of aquatic communities in conjunction with terrestrial studies.Geographically, much of my research is conducted in the Interior Highland, Southern Appalachians, and within the Wetlands theme(e.g., coastal plain and bottomland hardwoods systems).Collaborative work combining my primary research areas with other aspects of the aquatic community (invertebrates, periphytohn, productivity, riparian systems) and upslope research activities is of high personal interest.I see great opportunities for collaborative research of all aspects of riparian zone structure and function.Research of riparian zones, as transition from terrestrial to aquatic ecosystems, affords an opportunity to provide information needed by both the forest industry and the National orest System in the Southern Region.
