The Reptile Gut Microbiome: Its Role In Host Evolution And Community Assembly, Timothy John Colston Jan 2017

The Reptile Gut Microbiome: Its Role In Host Evolution And Community Assembly, Timothy John Colston

Electronic Theses and Dissertations

I characterize the endogenous (gut) microbiome of Squamate reptiles, with a particular focus on the suborder Serpentes, and investigate the influence of the microbiome on host evolution and community assembly using samples I collected across three continents in the New and Old World. I developed novel methods for sampling the microbiomes of reptiles and summarized the current literature on non-mammalian gut microbiomes. In addition to establishing a standardized method of collecting and characterizing reptile microbiomes I made novel contributions to the future direction of the burgeoning field of host-associated microbiome research. Through persistent and rigorous fieldwork I amassed the largest …
