Species-specific patterns in bivalve larval supply to a coastal embayment
(Massachusetts Institute of Technology, 2011)
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 ...
Microbial production and consumption of marine dissolved organic matter
(Massachusetts Institute of Technology, 2013)
Marine phytoplankton are the principal producers of oceanic dissolved organic matter (DOM), the organic substrate responsible for secondary production by heterotrophic microbes in the sea. Despite the importance of DOM in ...
Prochlorococcus genetic transformation and genomics of nitrogen metabolism
(Massachusetts Institute of Technology, 2005)
Prochlorococcus, a unicellular cyanobacterium, is the most abundant phytoplankton in the oligotrophic, oceanic gyres where major plant nutrients such as nitrogen (N) and phosphorus (P) are at nanomolar concentrations. ...
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 ...
Echolocation-based foraging by harbor porpoises and sperm whales, including effects of noise and acoustic propagation
(Massachusetts Institute of Technology, 2008)
In this thesis, I provide quantitative descriptions of toothed whale echolocation and foraging behavior, including assessment of the effects of noise on foraging behavior and the potential influence of ocean acoustic ...
Evolutionary and ecological genomics in deep-sea organisms
(Massachusetts Institute of Technology, 2015)
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 ...
