Mark-recapture statistics and demographic analysis
(Massachusetts Institute of Technology, 2002)
Mark-recapture analysis of populations is becoming an important tool in population biology. Mark-recapture methods can be used to estimate transition probabilities among life-stages from capture histories of marked individuals ...
Functional characterization and expression of molluscan detoxification enzymes and transporters involved in dietary allelochemical resistance
(Massachusetts Institute of Technology, 2008)
Understanding how organisms deal with potentially toxic or fitness-reducing allelochemicals is important for understanding patterns of predation and herbivory in the marine environment. The ability of marine consumers to ...
Approaches for assessing the presence and impact of thyroid hormone disrupting chemicals in Delphinid cetaceans
(Massachusetts Institute of Technology, 2006)
Cetacean blubber is a primary site for lipid storage, which the animal utilizes during periods of energetic stress. It is important to understand how the blubber responds to factors such as ontogeny, water temperature, ...
Migratory patterns of American shad (Alosa sapidissima) revealed by natural geochemical tags in otoliths
(Massachusetts Institute of Technology, 2007)
Geochemical signatures in the otoliths of diadromous fishes may allow for retrospective analyses of natal origins. In an assessment of river-specific signatures in American shad (Alosa sapidissima), an anadromous clupeid ...
Biophysical coupling between turbulence, veliger behavior, and larval supply
(Massachusetts Institute of Technology, 2005)
The goals of this thesis were to quantify the behavior of gastropod larvae (mud snails Ilyanassa obsoleta) in turbulence, and to investigate how that behavior affects larval supply in a turbulent coastal inlet. Gastropod ...
Spatial and temporal population genetics at deep-sea hydrothermal vents along the East Pacific Rise and Galápagos Rift
(Massachusetts Institute of Technology, 2008)
Ecological processes at deep-sea hydrothermal vents on fast-spreading mid-ocean ridges are punctuated by frequent physical disturbance. Larval dispersal among disjunct vent sites facilitates the persistence of sessile ...
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 ...
Life cycle evolution and systematics of Campanulariid hydrozoans
(Massachusetts Institute of Technology, 2004)
The purpose of this thesis is to study campanulariid life cycle evolution and systematics. The Campanulariidae is a hydrozoan family with many life cycle variations, and provide an excellent model system to study life cycle ...
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 ...
Biomechanics of North Atlantic right whale bone : mandibular fracture as a fatal endpoint for blunt vessel-whale collision modeling
(Massachusetts Institute of Technology, 2007)
The North Atlantic right whale, Eubalaena glacialis, one of the most critically endangered whales in the world, is subject to high anthropogenic mortality. Vessel-whale collisions and entanglement in fishing gear were ...
