Investigating Dispersal Ability To Infer Diversification In The Birds Of Madagascar, Robert D. Lauer
Investigating Dispersal Ability To Infer Diversification In The Birds Of Madagascar, Robert D. Lauer
Master's Theses
The objective of this study was to investigate whether dispersal ability, as measured by a proxy of hand-wing index 2, influenced diversification of the birds of Madagascar at two scales. Madagascar is home to several avian lineages that have diversified greatly while other lineages are only represented by a single species. a key question in evolutionary biology is why some of these lineages diversified while others did not. One way to address this is to examine what features of these lineages promotes their diversification. Recent studies have focused on the relative importance of dispersal ability to diversification at the continental …

Using phylogenetic and phylogeographic tools to uncover hidden diversity within the genus Newtonia in Madagascar
Madagascar is known for its rich biodiversity and high level of endemic species that are found nowhere else. Cryptic diversification, defined as genetically and evolutionarily distinct species that are hard to detect because they are morphologically indistinguishable from their closest relatives, has been hypothesized to occur in many groups on Madagascar. Currently it is unclear to what extent this phenomenon occurs in birds because only a few studies have been conducted. My study examined the phylogenetic and phylogeographic patterns within a songbird genus, Newtonia, that …

Biology: Faculty Publications and Other Works
A long-standing view of Indian biodiversity is that while rich in species, there are few endemics or in-situ radiations within the subcontinent. One exception is the Western Ghats biodiversity hotspot, an isolated mountain range with many endemic species. Understanding the origins of the montane-restricted species is crucial to illuminate both taxonomic and environmental history.
