WALTERS, DAVID M., M. J. BLUM, N. BURKHEAD, B. FREEMAN, B. RASHLEIGH, AND B. PORTER. INVASION DYNAMICS OF RED SHINERS (CYPRINELLA LUTRENSIS) IN SOUTHEASTERN STREAMS. Presented at American Fisheries Society, Anchorage, AL, September 11 - 15, 2005.
Impact/Purpose:
The goals of this research are to:
(1) determine how landscape characteristics relate to the spread of red shiner through southeastern river systems,
(2) identify behavioral and genetic mechanisms underlying interspecific hybridization, and
(3) develop models to assess the vulnerability of tributary streams to invasion by red shiner.
Description:
Red shiners have invaded a range of North American ecosystems, including several southeastern U.S. river drainages. A principle consequence of these invasions is extirpation of native congeners, either through competition or hydridization. We are conducting research to identify the key ecological and genetic drivers of red shiner colonization across the Coosa River system in Georgia and Alabama.
