Meeting Abstract
P2.115 Tuesday, Jan. 5 Biogeographic Patterns in Morphologically Conserved and Genetically Diverse Anuran Lineages from the Sunda Shelf STREICHER, J.W.*; HARVEY, M.B.; SMITH, E.N.; Univ. of Texas, Arlington; Broward College; Univ. of Texas, Arlington streicher@uta.edu
The Sunda Shelf includes peninsular Malaysia and much of western Indonesia. Climate induced land bridge formation and geologic uplift have shaped the complex biogeography of this region. While biogeographic patterns are known for many vertebrates from the Sunda Shelf, they remain poorly studied in anurans, especially among species from the islands of Sumatra and Java. Using combined evidence from molecules (mitochondrial DNA [mtDNA]) and morphology (multivariate morphometrics), we examined levels of diversity in fanged (Anura: Dicroglossidae), true (Anura: Ranidae), and parachuting (Anura: Rhacophoridae) frogs from Sumatra and Java. For comparative purposes, we also included data for select species from Borneo. We investigated phylogeographic, genetic, and morphological patterns in these anuran groups and report several instances of syntopic yet highly divergent mtDNA haplogroups in morphologically similar taxa.
