“Now is life very solid or very shifting?” Virginia Woolf asks in her diary of 1931, a question she claims haunts her in its contradictions. This dynamism between the solid and the shifting aspects of life and temporality is fundamental to an analysis of Woolf’s writing process. …

Understanding The Relationship Between Hosts And Their Microbiome, Boahemaa Adu-Oppong

Arts & Sciences Electronic Theses and Dissertations

Microbes are bountiful and associated with every animal and plant kingdom. Furthermore, microbes can alter host phenotype, development, health and functioning. However, this is not a one-way interaction, hosts can structure microbial communities by changing the environment to be suitable for certain microbial species. Several studies have characterized microbial communities associated with hosts to answer two2 main questions in ecology: who’s there, and what are they doing? However, two questions from the field of community ecology are often ignored (1) what forces are structuring the microbial communities (how was the community formed) and (2) how stable are these communities.

Beta-Diversity Patterns And Community Assembly Across Latitudes, Emma Moran

Arts & Sciences Electronic Theses and Dissertations

A major goal of community ecology is in understanding variation in community composition, generally termed β-diversity. This variation can result from a variety of mechanisms, including deterministic factors, wherein species sort along biotic or abiotic gradients; stochastic processes, whereby random fluctuations in population sizes cause variation in community composition; and/or dispersal limitation. Although all of these processes are likely occurring in all biological communities, a key question in community ecology research is if their relative importance may vary systematically across environmental or biogeographic gradients. In this dissertation, we combine both observational and experimental research to investigate β-diversity across a biogeographic …
