| deciphering ecological barriers to north american river otter (lontra canadensis) gene flow in the louisiana landscape. | for north american river otters (lontra canadensis) in louisiana, statewide distribution, availability of aquatic habitats, and the absence of physical barriers to dispersal might suggest that they exist as a large, panmictic population. however, the wide variety of habitat types in this region, and the dynamic nature of these habitats over time, could potentially structure river otter populations in accordance with cryptic landscape features. recently developed landscape genetic models offer a ... | 2008 | 18316322 |
