| prevalence of infection by batrachochytrium dendrobatidis and ranavirus in eastern hellbenders (cryptobranchus alleganiensis alleganiensis) in eastern tennessee. | hellbenders (n=97) were collected from the little and hiwassee rivers in eastern tennessee, usa, during 2009 and 2010. location and morphometrics for each animal were recorded, and nonlethal tissue samples were collected to estimate the prevalence of infection with batrachochytrium dendrobatidis (bd) and ranavirus in each watershed and year. real-time polymerase chain reaction was performed on skin swabs for bd and on tail clips for ranaviruses. overall prevalences of dna of bd, ranavirus, and c ... | 2012 | 22740521 |
| population genetics of the eastern hellbender (cryptobranchus alleganiensis alleganiensis) across multiple spatial scales. | conservation genetics is a powerful tool to assess the population structure of species and provides a framework for informing management of freshwater ecosystems. as lotic habitats become fragmented, the need to assess gene flow for species of conservation management becomes a priority. the eastern hellbender (cryptobranchus alleganiensis alleganiensis) is a large, fully aquatic paedamorphic salamander. many populations are experiencing declines throughout their geographic range, yet the genetic ... | 2013 | 24204565 |
| importance of demographic surveys and public lands for the conservation of eastern hellbenders cryptobranchus alleganiensis alleganiensis in southeast usa. | comparisons of recent and historic population demographic studies of eastern hellbenders cryptobranchus alleganiensis alleganiensis have identified significant population declines and extirpations associated with habitat degradation, poor water quality and disease, leading to nomination as a candidate for listing under the endangered species act. however, populations in the southern appalachian region of the range have received less attention despite relatively high levels of watershed protectio ... | 2017 | 28594881 |
