Evolutionary conservation and characterization of the metazoan amino acid response
(Massachusetts Institute of Technology, 2018)
Signaling pathways that respond to stress and sense nutrient availability are highly conserved throughout eukaryotes. In mammalian cells, these pathways have evolved to regulate immune responses, representing important ...
Spationtemporal population genomics of marine species : invasion, expansion, and connectivity
(Massachusetts Institute of Technology, 2017)
Every genome tells a story. This dissertation contains four such stories, focused on shared themes of marine population dynamics and rapid change, with an emphasis on invasive marine species. Biological invasions are often ...
Alexandrium catenella cyst dynamics in a coastal embayment : temperature dependence of dormancy, germination, and bloom initiation
(Massachusetts Institute of Technology, 2017)
Blooms of the dinoflagellate Alexandrium catenella cause paralytic shellfish poisoning syndrome and present an expanding public health threat. They are inoculated through the germination of benthic cysts, a process regulated ...
Trait-based modeling of larval dispersal in the Gulf of Maine
(Massachusetts Institute of Technology, 2017)
Population connectivity is a fundamental process that governs the spatial and temporal dynamics of marine ecosystems. For many marine species, population connectivity is driven by dispersal during a planktonic larval phase. ...
Optimal bioeconomic management of changing marine resources
(Massachusetts Institute of Technology, 2016)
Marine populations are increasingly subjected to changing conditions whether through harvest or through broad-scale habitat change. Historically, few models have accounted for such trends over time, and even fewer have ...
Ciliate micrograzer dynamics of the New England shelf
(Massachusetts Institute of Technology, 2017)
Protists play important roles in grazing and nutrient recycling, but quantifying these roles has been hindered by difficulties in collecting, culturing, and observing these often-delicate cells. During long-term deployments ...
Evolutionary and ecological genomics in deep-sea organisms
(Massachusetts Institute of Technology, 2015)
Hydrothermal vents and coral ecosystems are conspicuous biological hot spots in the deep-sea. These ecosystems face increasing threats from human activities. Having thorough taxonomic inventories as well as understanding ...
