Vines In The Neotropics: Phylogenomics, Biogeography And Systematics In Passion Flowers (Passiflora Subgenus Decaloba Section Decaloba), Serena Acha
Dissertations
With 600 species, Passiflora is a large, morphologically complex and broadly distributed genus in Passifloraceae that represents a major challenge to scientists interested in understanding the evolutionary history of tropical vines. Passiflora has been divided into subgenera, super sections and sections. One of the most enigmatic and species-rich (~120 spp.) groups in Passiflora is section Decaloba, which occurs in the Neotropics and is particularly diverse in Andean montane forests. In this study, we used phylogenomic and population genomic approaches to investigate the evolutionary history, biologeography, species boundaries, and taxonomy of Passiflora section Decaloba. We sampled herbarium specimens, extracted …
Taxonomy, Species Limits, And Phylogenetic Relationships Of Anoura Gray 1838 (Chiroptera: Phyllostomidae), Camilo Andres Calderon Acevedo
Taxonomy, Species Limits, And Phylogenetic Relationships Of Anoura Gray 1838 (Chiroptera: Phyllostomidae), Camilo Andres Calderon Acevedo
Dissertations
This dissertation addresses several aspects of the diversity and species limits in the nectarivorous bat genus Anoura Gray 1838(Chiroptera: Glossophaginae). Based on morphometric approaches, the current taxonomic arrangement for Anoura includes 8 to 10 species; however, previous taxonomic revisions did not include all closely related species in the genus. In Chapter 1, I investigate the identity of Anoura carishina and its position in the morphospace of the large-bodied Anoura using craniodental and external variables. I analyze traits thought to be diagnostic for these species, including 1) an elliptical Fourier transformation analysis of the shape of the third upper premolar …
