Investigating Species Boundaries And Taxonomy In The California Pincushion Plants, Theresa Saunders, Leigh Johnson
Journal of Undergraduate Research
Species in the genus Navarretia are annual wildflowers found almost exclusively in California. The Navarretia atractyloides group consists of just two species, N. atractyloides and N. hamata, that are more similar to each other morphologically than to any other Navarretia species. The most recent taxonomic investigation of these two species distinguishes between them based on bract shape, stamen attachment to the corolla, and whether the style is included and anthers included to slightly exserted from the corolla tube versus style exserted and anthers long exserted (Day, 1993). However, we have noticed that some specimens that seem to be …
Phylogenetics, Biogeography, And Patterns Of Diversification Of Geckosacross The Sunda Shelf With An Emphasis On The Genuscnemaspis (Strauch, 1887), Perry Lee Wood
Theses and Dissertations
In my dissertation I investigate two genera of geckos (Cyrtodactylus and Cnemaspis) that are distributed across Southeast Asia with an emphasis on Cnemaspis. In Chapter 1 I use a multilocus dataset, ancestral area analyses, and molecular clock dating to generate a species level time calibrated phylogeny to test the monophyly of Cyrtodactylus and to identify major biogeographical patterns. I identified that Cyrtodactylus is monophyletic only if the the Sri Lankan genus often recognized as Geckoella is included. The results of the Biogeographical analyses reveal a west to east pattern of diversification. Chapter 2 I use a traditional morphological dataset to …
