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 ...
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 ...
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 ...
Recruitment of the intertidal barnacle Semibalanus balanoides : metamorphosis and survival from daily to seasonable timescales
(Massachusetts Institute of Technology, 2008)
The benthic habitat is the terminal destination for marine animals in terms of their reproductive lifecycle. Recruitment dynamics relating to seasonal changes in the benthic habitat may be the best source of information ...
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 ...
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 ...
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 ...
Distribution, patchiness, and behavior of Antarctic zooplankton, assessed using multi-frequency acoustic techniques
(Massachusetts Institute of Technology, 2006)
The physical and biological forces that drive zooplankton distribution and patchiness in an antarctic continental shelf region were examined, with particular emphasis on the Antarctic krill, Euphausia superba. This was ...
Orchestration : the movement and vocal behavior of free-ranging Norwegian killer whales (Orcinus orca)
(Massachusetts Institute of Technology, 2008)
Studying the social and cultural transmission of behavior among animals helps to identify patterns of interaction and information content flowing between individuals. Killer whales are likely to acquire traits culturally ...
