N₂ fixation by subsurface populations of Trichodesmium : an important source of new nitrogen to the North Atlantic Ocean
… is an important contributor to the marine nitrogen (N) and carbon (C) cycles. The extent to which Trichodesmium dinitrogen (N2) fixation contributes to the marine N cycle has been modeled based on abundance data and rate estimates from surface populations. However, recent data show that …

The auditory system of the minke whale (Balaenoptera acutorostrata) : a potential fatty sound reception pathway in a mysticete cetacean
… whales (suborder Mysticeti), we lack basic information about their auditory physiology for comprehensive risk assessments. Hearing ranges and sensitivities could be measured if customized equipment and methods were developed based on how baleen whales receive sound. However, sound reception …

Impacts of developmental exposures to the harmful algal bloom toxin domoic acid on neural development and behavior
… algal blooms (HABs) can produce potent neurotoxins that accumulate in seafood and affect human health. One HAB toxin of concern is domoic acid (DomA), a glutamate analog produced by the marine diatom Pseudo-nitzschia spp. Current regulatory limits are designed to prevent acute neurotoxicity in …

Trait-based modeling of larval dispersal in the Gulf of Maine
… a fundamental process that governs the spatial and temporal dynamics of marine ecosystems. For many marine species, population connectivity is driven by dispersal during a planktonic larval phase. The ability to obtain accurate, affordable, and meaningful estimates of larval dispersal patterns …

Form, function and flow in the plankton : jet propulsion and filtration by pelagic tunicates
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 explored. Observations and experiments were conducted at the Liquid Jungle …

Larval ecology and synchronous reproduction of two crustacean species : Semibalanus balanoides in New England, USA and Gecarcinus quadratus in Veraguas, Panama
… cues for synchronous reproduction were investigated for two highly abundant, ecologically important crustacean species: the temperate acorn barnacle, Semibalanus balanoides, and the tropical terrestrial crab, Gecarcinus quadratus. Larval ecology of these two species was also studied to …

Productivity, metabolism and physiology of free-living Chemoautotrophic Epsilonproteobacteria
… at deep-sea hydrothermal vents were discovered in 1977, but not until 1995 were free-living autotrophic Epsilonproteobacteria identified as important microbial community members. Because the deep-sea is food-starved, the autotrophic metabolism of hydrothermal vent Epsilonproteobacteria may be …

Optimal bioeconomic management of changing marine resources
Marine populations are increasingly subjected to changing conditions whether through harvest or through broad-scale habitat change. Historically, few models have accounted for such trends over time, and even fewer have been used to study how trends affect optimal harvests. I developed and analyzed …

Evolutionary and ecological genomics in deep-sea organisms
Hydrothermal vents and coral ecosystems are conspicuous biological hot spots in the deep-sea. These ecosystems face increasing threats from human activities. Having thorough taxonomic inventories as well as understanding species' relatedness, genetic diversity, connectivity patterns, and adaptive …

Physiological and behavioral responses, and their variability, in squid, Doryteuthis pealeii, embryos and paralarvae reared under chronic ocean acidification
Ocean acidification (OA) and related stressors, like warming, are occurring rapidly in coastal systems. There is concern about the impacts these stressors may have on the early development of species that use the nearshore as nursery habitat. The inshore longfin squid, Doryteuthis pealeii, plays an …

Functional connectivity of coral reef fishes in a tropical seascape assessed by compound-specific stable isotope analyses
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 seagrass beds as juvenile nurseries before migrating to coral reefs as adults. …

Coral reef soundscapes: spatiotemporal variability and links to species assemblages
… of environmental changes. Reefs are constantly in a state of flux: the resident species assemblages vary considerably in space and time. However, the drivers of this variability are poorly understood. Tracking these changes and studying how coral reefs respond to natural and anthropogenic …

Age, movements, and feeding ecology of northwest Atlantic white sharks estimated from ecogeochemical profiles in vertebrae
… migratory, ecologically important, vulnerable, and understudied marine predators. Ecogeochemistry, which takes advantage of natural variations in chemical signatures recorded in body tissues, can help determine lifetime movement, age, and ontogenetic diet history in difficult to study species. …

Alexandrium catenella cyst dynamics in a coastal embayment : temperature dependence of dormancy, germination, and bloom initiation
Blooms of the dinoflagellate Alexandrium catenella cause paralytic shellfish poisoning syndrome and present an expanding public health threat. They are inoculated through the germination of benthic cysts, a process regulated by internal and environmental factors, most importantly temperature. Less …

Species-specific patterns in bivalve larval supply to a coastal embayment
Larval supply is an important process linking reproductive output to recruitment of benthic marine invertebrates. Few species-specific studies of bivalve larvae have been performed due to the lack of suitable methods for species identification. This thesis focused on applying a method to identify …

Life cycle studies of the red tide dinoflagellate species complex Alexandrium tamarense
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 related nontoxic A. tamarense also occur, sometimes in close geographical …
