Involvement of cytochrome P450 1A in the toxicity of aryl hydrocarbon receptor agonists : alteration of arachidonic and acid metabolism and production of reactive oxygen species
(Massachusetts Institute of Technology, 1998)
Two cytochrome P4501A-dependent mechanisms of aryl hydrocarbon receptor (AhR) agonist toxicity were examined in the marine teleost scup (Stenotomus chrysops), alteration of arachidonic acid (AA) metabolism and production ...
The ecology, life history, and phylogeny of the marine thecate heterotrophic dinoflagellates Protoperidinium and Diplopsalidaceae (Dinophyceae)
(Massachusetts Institute of Technology, 2006)
Marine thecate heterotrophic dinoflagellates likely play an important role in the consumption of primary productivity and in the trophic structure of the plankton, yet we know little about these species. This thesis expanded ...
Metapopulation dynamics of the softshell clam, Mya arenaria
(Massachusetts Institute of Technology, 2008)
In this dissertation, I explored metapopulation dynamics and population connectivity, with a focus on the softshell clam, Mya arenaria. I first worked towards developing a method for using elemental signatures retained in ...
Prochlorococcus genetic transformation and genomics of nitrogen metabolism
(Massachusetts Institute of Technology, 2005)
Prochlorococcus, a unicellular cyanobacterium, is the most abundant phytoplankton in the oligotrophic, oceanic gyres where major plant nutrients such as nitrogen (N) and phosphorus (P) are at nanomolar concentrations. ...
Iron and Prochlorococcus/
(Massachusetts Institute of Technology, 2009)
Iron availability and primary productivity in the oceans are intricately linked through photosynthesis. At the global scale we understand how iron addition induces phytoplankton blooms through meso-scale iron-addition ...
Sound use, sequential behavior and ecology of foraging bottlenose dolphins, Tursiops truncatus
(Massachusetts Institute of Technology, 1999)
Odontocetes are assumed to use echolocation for navigation and foraging, but neither of these uses of biosonar has been conclusively demonstrated in free-ranging animals. Many bats are known to use echolocation throughout ...
Diversity of the marine cyanobacterium Trichodesmium : characterization of the Woods Hole culture collection and quantification of field populations
(Massachusetts Institute of Technology, 2009)
Trichodesmium is a colonial, N2-fixing cyanobacterium found in tropical oceans. Species of Trichodesmium are genetically similar but several species exist together in the same waters. In order to coexist, Trichodesmium ...
Diversity and characterization of novel Cytochrome P450 2 genes in the marine teleost Fundulus Heteroclitus
(Massachusetts Institute of Technology, 1998)
Behavioral ecology of coral reef fishes at spawning aggregation sites
(Massachusetts Institute of Technology, 1998)
Pteropod shell condition, locomotion, and long-term population trends in the context of ocean acidification and environmental change
(Massachusetts Institute of Technology, 2017)
Thecosome pteropods are planktonic mollusks that form aragonite shells and that may experience increased dissolution and other adverse effects due to ocean acidification. This thesis focuses on assessing the possible ...
