Frogs Hiding In Plain Sight: Phylogenetic Systematics Of Myanmar’S Occidozyga Species Complex, And The Identification Of A Novel Species, Allison Bogisich
Master's Theses
Different species can be difficult to distinguish from one another when they are morphologically similar. Such cryptic species are the reason many anuran species go undetected. For this study, the taxonomic identity of the Occidozyga complex across Myanmar was investigated. An integrated approach was used combining molecular, morphological and phylogeographic data to better assess its taxonomy. Results indicate the presence of three new candidate species within Occidozyga, and three evolutionarily significant unit (ESU) lineages. Two mitochondrial gene fragments (16S, COI) and one nuclear gene fragment (Rhodopsin) were examined from DNA isolated from forty-seven preserved specimens from the California Academy …

The Conservation Genetics Of Two Emydid Turtles: Emydoidea Blandingii And Malaclemys Terrapin, Charlotte Lizana Petre
Master's Theses
Conservation of turtles is complicated by their sensitivity to habitat degradation and overexploitation. I used microsatellites and standard population genetic analyses to explore genetic diversity, population structure, paternity and demographic history in two emydid turtles that are currently experiencing threats to their survival. The Blanding’s turtle, Emydoidea blandingii, has experienced habitat fragmentation throughout its range, and this study focuses on a population in Massachusetts where hatchlings from one population are being translocated to establish a new population. I found evidence of multiple paternity within clutches and found no significant reduction in genetic diversity when comparing the source population and …
