Comparative Phylogeography Across Multiple Scales: Small Mammals, Their Ecology, Pathogens, And Drivers Of Diversification, Schuyler W. Liphardt
Comparative Phylogeography Across Multiple Scales: Small Mammals, Their Ecology, Pathogens, And Drivers Of Diversification, Schuyler W. Liphardt
Biology ETDs
Comparative phylogeography has historically been defined as the study of how genetic variation of co-distributed species has been shaped by biogeographical history. This is a mature field of study out of which several techniques have been developed directed at identifying the role ecology and geography in diversification patterns across time. I employ the tools developed in classical comparative phylogeography across multiple taxonomic scales and across regions that historically have been understudied. My first two chapters study the complex history of host-switching, codiversification, and reassortment of hantaviruses in their mammal hosts across North America. By taking a host-centric comparative phylogeographic approach …
Phylogeography, Diversification, And Historical Demography Of The White-Toothed Rats (Berylmys) In Indochina, Kristy Lee Tuttle
Phylogeography, Diversification, And Historical Demography Of The White-Toothed Rats (Berylmys) In Indochina, Kristy Lee Tuttle
Graduate Research Theses & Dissertations
Berylmys, the White-toothed rats, and other members of the Rattus sl (Rattus, Maxomys, Leopoldamys, Niviventer, Bandicota, and Sundamys) evolved from 3-5 million years ago during a period of dynamic landscape change in Indochinese south Asia wherein climatically stable, warm forests of Miocene and Pliocene Indochina transitioned to a modern landscape regime. From the late Pliocene through the terminal Pleistocene, climate changes, ecological shifts, rising and falling sea levels, and tectonic uplift drove adaptive radiation within Rattus sl, in complex interactions that are still not completely understood. The goal of this study is to understand species relationships and population structure in …
