Ecology, diversity and comparative genomics of oceanic cyanobacterial viruses
(Massachusetts Institute of Technology, 2004)
The marine cyanobacteria Prochlorococcus and Synechococcus are numerically dominant primary producers in the oceans. Each genera consists of multiple physiologically and genetically distinct groups (termed "ecotypes" in ...
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, ...
Techniques for studying vocal learning in bottlenose dolphins, Tursiops truncatus
(Massachusetts Institute of Technology, 1999)
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 ...
Genes and structural proteins of the phage SYN5 of the marine cyanobacteria, Synechococcus
(Massachusetts Institute of Technology, 2005)
Bacteriophage have been proposed to be the most abundant organisms on the planet, at an estimated 10³¹ particles globally (Hendrix et al., 1999). The majority of bacteriophage isolates (96%) are double-stranded DNA tailed ...
Mitochondrial genomics and northwestern Atlantic population genetics of marine annelids
(Massachusetts Institute of Technology, 2005)
The overarching goal of this thesis was to investigate marine benthic invertebrate phylogenetics and population genetics, focused on the phylum Annelida. Recent expansions of molecular methods and the increasing diversity ...
Development of a "genome-proxy" microarray for profiling marine microbial communities, and its application to a time series in Monterey Bay, California
(Massachusetts Institute of Technology, 2008)
This thesis describes the development and application of a new tool for profiling marine microbial communities. Chapter 1 places the tool in the context of the range of methods used currently. Chapter 2 describes the ...
Involvement of cytochrome P450 1A in the toxicity of aryl hydrocarbon receptor agonists : alteration of arachidonic and acid metabolism and production of reactive oxygen species
(Massachusetts Institute of Technology, 1998)
Two cytochrome P4501A-dependent mechanisms of aryl hydrocarbon receptor (AhR) agonist toxicity were examined in the marine teleost scup (Stenotomus chrysops), alteration of arachidonic acid (AA) metabolism and production ...
The ecology, life history, and phylogeny of the marine thecate heterotrophic dinoflagellates Protoperidinium and Diplopsalidaceae (Dinophyceae)
(Massachusetts Institute of Technology, 2006)
Marine thecate heterotrophic dinoflagellates likely play an important role in the consumption of primary productivity and in the trophic structure of the plankton, yet we know little about these species. This thesis expanded ...
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 ...
