Metapopulation dynamics of the softshell clam, Mya arenaria
(Massachusetts Institute of Technology, 2008)
In this dissertation, I explored metapopulation dynamics and population connectivity, with a focus on the softshell clam, Mya arenaria. I first worked towards developing a method for using elemental signatures retained in ...
Integrating bioenergetics and foraging behavior : the physiological ecology of larval cod (Gadus morhua)
(Massachusetts Institute of Technology, 2004)
How do larval cod, Gadus morhua, balance foraging effort against the high cost of swimming in a viscous hydrodynamic regime? A respirometry system was developed to measure the activity metabolism of individual larvae. The ...
Interactions between calanoid copepod hosts and their associated microbiota
(Massachusetts Institute of Technology, 2015)
Zooplankton, such as copepods, are highly abundant environmental reservoirs of many bacterial pathogens. Although copepods are known to support diverse and productive bacterial communities, little is understood about whether ...
Behavioral responses of invertebrate larvae to water column cues
(Massachusetts Institute of Technology, 2016)
Many benthic marine invertebrates have two-phase life histories, relying on planktonic larval stages for dispersal and exchange of individuals between adult populations. Historically, larvae were considered passive drifters ...
Faunal biogeography, community structure, and genetic connectivity of North Atlantic seamounts
(Massachusetts Institute of Technology, 2008)
The mechanisms of faunal dispersal across ocean basins are key unknowns toward understanding of the modern biogeography and biodiversity of deep-sea fauna. Seamounts are considered to play a defining role in faunal evolution, ...
Pteropod shell condition, locomotion, and long-term population trends in the context of ocean acidification and environmental change
(Massachusetts Institute of Technology, 2017)
Thecosome pteropods are planktonic mollusks that form aragonite shells and that may experience increased dissolution and other adverse effects due to ocean acidification. This thesis focuses on assessing the possible ...
Diversity of the marine cyanobacterium Trichodesmium : characterization of the Woods Hole culture collection and quantification of field populations
(Massachusetts Institute of Technology, 2009)
Trichodesmium is a colonial, N2-fixing cyanobacterium found in tropical oceans. Species of Trichodesmium are genetically similar but several species exist together in the same waters. In order to coexist, Trichodesmium ...
Behavioral ecology of coral reef fishes at spawning aggregation sites
(Massachusetts Institute of Technology, 1998)
Iron and Prochlorococcus/
(Massachusetts Institute of Technology, 2009)
Iron availability and primary productivity in the oceans are intricately linked through photosynthesis. At the global scale we understand how iron addition induces phytoplankton blooms through meso-scale iron-addition ...
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. ...
