Functional connectivity of coral reef fishes in a tropical seascape assessed by compound-specific stable isotope analyses
(Massachusetts Institute of Technology, 2011)
The ecological integrity of tropical habitats, including mangroves, seagrass beds and coral reefs, is coming under increasing pressure from human activities. Many coral reef fish species are thought to use mangroves and ...
Life cycle studies of the red tide dinoflagellate species complex Alexandrium tamarense
(Massachusetts Institute of Technology, 2011)
Blooms of toxic species within the algal dinoflagellate species complex Alexandrium tamarense may cause Paralytic Shellfish Poisoning, a significant and growing environmental threat worldwide. However, blooms of closely ...
Phosphorus physiology of the marine cyanobacterium Trichodesmium
(Massachusetts Institute of Technology, 2010)
Primary producers play a critical role in the oceanic food chain and the global cycling of carbon. The marine diazotroph Trichodesmium is a major contributor to both primary production and nitrogen fixation in the tropical ...
Modeling the processes affecting larval haddock (Melanogrammus aeglefinus) survival on Georges Bank
(Massachusetts Institute of Technology, 2011)
The ultimate goal of early life studies of fish over the past century has been to better understand recruitment variability. Recruitment is the single most important natural event controlling year-class strength and biomass ...
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 ...
The auditory system of the minke whale (Balaenoptera acutorostrata) : a potential fatty sound reception pathway in a mysticete cetacean
(Massachusetts Institute of Technology, 2012)
Despite widespread concerns about the effects of anthropogenic noise on baleen whales (suborder Mysticeti), we lack basic information about their auditory physiology for comprehensive risk assessments. Hearing ranges and ...
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 ...
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 ...
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 ...
