Predictability studies of coastal marine ecosystem behavior
… “Systems Ecology” became an important branch of biological oceanography since the fundamental text of Odum (1983). Since then, the holistic view on the ecosystem behavior has evolved, considering community and population processes as a “continuum of functional responses to changing conditions” …

Some nonlinear problems in plankton ecology
… is often considered a main determinant of biological pattern. A common approach to identifying key environmental forcings is to match scales of variability: fluctuations of a biological variable at a particular frequency are attributed to forcing by the physical environment at a similar …

Relationship of plankton and marine snow to hydrography and currents on the south portion of Georges Bank during June 1997
A key question in biological oceanography is how plankton populations maintain themselves in regions of favorable growth and survival in the face of horizontal transport by ocean currents. Plankton are thought to be retained on the highly productive Georges Bank by the clockwise flow, which …

Relationship of plankton and marine snow to hydrography and currents on the southwest portion of Georges Bank during June 1997
A key question in biological oceanography is how plankton populations maintain themselves in regions of favorable growth and survival in the face of horizontal transport by ocean currents. Plankton are thought to be retained on the highly productive Georges Bank by the clockwise flow, which …

Defining the ecological and physiological traits of phytoplankton across marine ecosystems
… has been a central problem in the field of biological oceanography for the past century. Molecular approaches enable the direct examination of species-specific metabolic profiles in mixed, natural communities, a task which was previously intractable. In this thesis, I developed and applied …

Analysis of Net Primary Production Models and Observations in the Tropical Pacific Ocean and Their Relationship with Fisheries Yield
<p>Primary production regulates fisheries yield, but testing the degree to which it is so is complicated by our limited ability to measure and model net primary production in the ocean. Herein, I analyze primary production and fisheries yields in the tropical Pacific Ocean, and how uncertainties in …

A molecular approach to questions in the phylogeny of planktonic sarcodines
… application of molecular biology to the field of biological oceanography offers alternative approaches to reexamining sarcodine phylogeny with the goal of producing classifications which reflect evolutionary history. The relationships of the Acantharea and the Polycystinea (order Spumellarida) to …

Characterization of microbial primary and secondary metabolism in the marine realm
This thesis applies meta-omics data analysis to elucidate the ecological roles of marine microorganisms in diverse habitats and includes the development of new bioinformatics tools to enhance these analyses. In my second chapter, I applied genome mining tools to analyze the gene content and …

Clams and climate: implications for measuring seasonality in the marine bivalve, saxidomus gigantea
Sclerochronological and sclerochemical analysis of shellfish remains from archaeological sites afford the opportunity to understand environmental change and its impacts on human populations through time. During the Late Holocene in the Gulf of Alaska, the paleoenvironmental record reflects …

Molecular mechanisms of microbial interactions in model systems and natural environments
Marine microbes are dominant life forms in the ocean and comprise dynamic populations of viruses, bacteria, archaea and single-celled eukaryotes. Interactions between marine microbes impact global biogeochemical cycles and form the base of marine food webs. Interactions range from symbiotic to …

Resolving the molecular ecology of marine microbial eukaryotes with metatranscriptomes
The surface waters of the North Pacific ocean host diverse populations of microbial eukaryotes, who collectively mediate the flux of energy and matter in their environment with a significant impact on global biogeochemical cycles. The evolutionary history of these organisms spans billions of years …

Biodiversity and Biogeography of Deep-Sea Gastropod Mollusks from the Pacific Costa Rica Margin
The deep ocean holds a diversity of life that remains to be discovered and described. Marine ecosystems fueled by chemosynthesis, such as hydrothermal vents and hydrocarbon seeps, represent biodiversity hotspots along the ocean floor. Yet, investigations into the diversity, genetic connectivity, …

Genes and structural proteins of the phage SYN5 of the marine cyanobacteria, Synechococcus
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 phages (Caudovirales). These phages possess a distinctive icosehedral head, …

Diversity of the marine cyanobacterium Trichodesmium : characterization of the Woods Hole culture collection and quantification of field populations
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 spp. may occupy different niche spaces through differential utilization of …
