| experimental infection of native north carolina salamanders with batrachochytrium dendrobatidis. | chytridiomycosis is an often fatal fungal disease of amphibians caused by batrachochytrium dendrobatidis. this disease has been implicated in the worldwide decline of many anuran species, but studies of chytridiomycosis in wild salamanders are limited. between august 2006 and december 2006, we tested wild amphibians in north carolina, usa (n=212) by polymerase chain reaction (pcr). we identified three pcr-positive animals: one rana clamitans and two plethodontid salamanders. we experimentally in ... | 2009 | 19617473 |
| genetic structure of the blue ridge dusky salamander (desmognathus orestes): inferences from allozymes, mitochondrial dna, and behavior. | the plethodontid salamander desmognathus orestes, a member of the d. ochrophaeus species complex, is distributed in southwestern virginia, eastern tennessee, and western north carolina. previous allozyme analyses indicate that d. orestes consists of two distinct groups of populations (d. orestes 'b' and d. orestes 'c') with extensive intergradation and probable gene flow between these two groups. spatially varying allele frequencies can reflect historical associations, current gene flow, or a co ... | 2001 | 11794788 |
