4.5 River Basins
undescribed species and investigations aimed at resolving taxonomic status are needed. In addition to the SGCN species found in the basin (see Table 4.78), a list of knowledge-gap priority species is provided in Table 4.79. • Study habitat use and life history characteristics of priority species (e.g., Bigeye Jumprock, Chowanoke Crayfsh, Green Floater, Least Brook Lamprey, Roanoke Logperch, Triangle Floater, and V-lip Redhorse). • Support taxonomic research for priority species (e.g., Cambarus sp. C complex and the mussel genus Elliptio) . • Support development of captive propagation techniques for priority species (e.g., Green Floater, Ironcolor Shiner, Orangefn Madtom, Roanoke Logperch, and Triangle Floater).
