Hypersaline Lake Environments Exhibit Reduced Microbial Dormancy, Joshua Christopher Vert
Hypersaline Lake Environments Exhibit Reduced Microbial Dormancy, Joshua Christopher Vert
Theses and Dissertations
From acid seeps and deep-sea thermal vents to glacial ice and hypersaline lakes, extreme environments contain relatively simplified communities consisting of extremophiles that have evolved to survive and thrive under adverse abiotic conditions. In more neutral environments, microorganisms use dormancy as a common life history strategy to weather temporal fluctuations of resources or stresses until more 'optimal' conditions are present. It is unclear if dormancy is an essential survival mechanism for microorganisms in extreme environments; however, recent studies suggest that extreme environments may create stable conditions for extremophiles to the extent that dormancy is of less ecological importance. Using lake …
