Functional genomics of a non-toxic Alexandrium lusitanicum culture
(Massachusetts Institute of Technology, 2007)
Paralytic shellfish poisoning (PSP) is a human intoxication associated with the consumption of shellfish contaminated with a family of neurotoxins called saxitoxins. Many species in the dinoflagellate genus Alexandrium ...
Faunal biogeography, community structure, and genetic connectivity of North Atlantic seamounts
(Massachusetts Institute of Technology, 2008)
The mechanisms of faunal dispersal across ocean basins are key unknowns toward understanding of the modern biogeography and biodiversity of deep-sea fauna. Seamounts are considered to play a defining role in faunal evolution, ...
Sands and environmental conditions impact the abundance and persistence of the fecal indicator bacteria Enterococcus at recreational beaches
(Massachusetts Institute of Technology, 2012)
The marine fecal indicator Enterococcus is measured at beaches to detect fecal contamination events, and beaches are closed to bathers when Enterococcus is found to exceed the federally mandated limit. This dissertation ...
Techniques for studying vocal learning in bottlenose dolphins, Tursiops truncatus
(Massachusetts Institute of Technology, 1999)
An investigation of the roles of geomagnetic and acoustic cues in whale navigation and orientation
(Massachusetts Institute of Technology, 2013)
Many species of whales migrate annually between high-latitude feeding grounds and low-latitude breeding grounds. Yet, very little is known about how these animals navigate during these migrations. This thesis takes a first ...
Iron limitation and the role of Siderophores in marine Synechococcus
(Massachusetts Institute of Technology, 2009)
Marine cyanobacteria in the genus Synechococcus are widely distributed and contribute significantly to global primary productivity. In many parts of the ocean their growth is limited by a lack of iron, an essential nutrient ...
Trace metals and the ecology of marine cyanobacteria
(Massachusetts Institute of Technology, 2000)
The marine cyanobacteria Synechococcus and Prochlorococcus are important primary producers in oligotrophic oceans. The abundance and cell division rates of these cyanobacteria can be influenced by trace metals such as iron ...
Comparative analyses of aryl hydrocarbon receptor structure, function, and evolution in marine mammals
(Massachusetts Institute of Technology, 2007)
Marine mammals possess high body burdens of persistent organic pollutants, including PCBs and dioxin-like compounds (DLC). Chronic environmental or dietary exposure to these chemicals can disrupt the function of reproductive ...
Molecular insights into the niche of harmful brown tides
(Massachusetts Institute of Technology, 2011)
Recurrent brown tide blooms caused by the harmful alga Alureococcus anophagefferens have decimated coastal ecosystems and shellfisheries along the Eastern U.S and South Africa. The exact mechanisms controlling bloom ...
Adult demography and larval processes in coastal benthic populations : intertidal barnacles in Southern California and Baja California
(Massachusetts Institute of Technology, 2005)
The geographic distribution and dynamics of coastal benthic populations are shaped by physical - biological interactions affecting larval dispersal and the demography of juvenile and adult individuals. This thesis focused ...
