Theses and Dissertations
The ability of ecosystems to adapt to environmental perturbations depends on the duration and intensity of change and the overall biological diversity of the system. In this study, a microbial mat ecosystem located on San Salvador Island, the Bahamas was used as a model to examine how environmental disturbance affects microbial community resistance, their protein synthesis potential (PSP), ecosystem function as measured by biogeochemical cycling, community stability, and resilience. This ecosystem experienced a large shift in salinity (230 to 65 g kg-1) during 2011–2012 following the landfall of Hurricane Irene on San Salvador Island. High throughput sequencing and analysis of …
