Abstract Details

2008, Master of Science (MS), Ohio University, Environmental Studies (Arts and Sciences).
A disjunct population of G. ouachitensis co-exists and interacts with G. geographica a more abundant and geographically widespread riverine species. Visual surveys in the spring of 2008 from Commercial Point to Portsmouth, OH (200km), show patchy distribution of G. ouachitensis whereas G. geographica appears more widespread. G. ouachitensis prefers wider river areas and habitats closer to shallow bars than G. geographica. However, G. geographica prefers habitats closer to tributaries than G. ouachitensis. I monitored both species during 2007 using radiotelemetry in a four-mile river reach by evaluating their habitats and species distribution using quantitative methods in GIS. Results show that G. ouachitensis prefers finer substrate and deeper water than G.geographica and random points. The habitat range examined by the adaptive local convex-hull (LoCoH) method reveals that the two species marginally overlap. Population estimates appear stable but may need monitoring should this environment change in subsequent years.
