Uncovering Cryptic Diversity Of Desmognathine Salamanders In The Cumberland Plateau Utilizing Molecular Genetic Techniques, Katherine E. Ray
Honors Theses
Cryptic species are difficult to identify morphologically; therefore, their distributions are often poorly understood. However, species distributions are critical for evaluating biodiversity in ecology and biodiversity. Dusky salamanders (Desmognathus) are an example of species of North American salamanders that have been particularly difficult to classify. Specifically, in the southern Cumberland Plateau, the dusky salamanders’ distributions are unknown. Desmognathus fuscus and D. conanti have been found to the north and south of the southern Cumberland Plateau, respectively. However, they have not been adequately sampled in this region. I studied genetic variation in the mitochondrial gene CytB in Desmognathus salamanders sampled from …
