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 ...
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 ...
Growth and development of larval bay scallops (Argopecten irradians) in response to early exposure to high CO₂
(Massachusetts Institute of Technology, 2013)
Coastal and estuarine environments experience large variability and rapid shifts in pCO₂ levels. Elevated pCO², or ocean acidification, often negatively affects early life stages of calcifying marine invertebrates, including ...
Biology and potential biogeochemical impacts of novel predatory flavobacteria
(Massachusetts Institute of Technology, 2010)
Predatory bacteria are ubiquitous in aquatic environments and may be important players in the ecology and biogeochemistry of microbial communities. Three novel strains belonging to two genera of marine flavobacteria, Olleya ...
Larval ecology and synchronous reproduction of two crustacean species : Semibalanus balanoides in New England, USA and Gecarcinus quadratus in Veraguas, Panama
(Massachusetts Institute of Technology, 2011)
The environmental cues for synchronous reproduction were investigated for two highly abundant, ecologically important crustacean species: the temperate acorn barnacle, Semibalanus balanoides, and the tropical terrestrial ...
Form, function and flow in the plankton : jet propulsion and filtration by pelagic tunicates
(Massachusetts Institute of Technology, 2010)
Trade-offs between filtration rate and swimming performance among several salp species with distinct morphologies and swimming styles were compared. Small-scale particle encounter at the salp filtering apparatus was also ...
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 ...
