THE PHYSIOLOGICAL RESPONSE OF PICOPHYTOPLANKTON TO LIGHT, TEMPERATURE AND NUTRIENTS, INCLUDING CLIMATE CHANGE MODEL SIMULATIONS
… for picoprokaryotes (0.81 − 1.44 d-1) than for picoeukaryotes (1.93 − 4.93 d-1). Also, their affinity for light is higher (7.15 − 12.42 g C m2 (mol photons g Chl)-1 compared to 3.42 − 9.81 g C m2 (mol photons g Chl)-1). Optimum growth rates differ significantly between the groups (0.47 ± 0.17 …

Picophytoplankton of the Northeast U.S. Shelf: community composition and dynamics
… and loss rates for a nearshore community of picoeukaryotes over a 16-year period. I compare their cell concentrations, vital rates, and responses to environmental variables to those of the cyanobacteria, Synechococcus. Next, to reveal how these dynamics relate to changes in community …

The ecology of picophytoplankton in a coastal upwelling ecosystem
… groups, Synechococcus, Prochlorococcus and picoeukaryotes, which are the three most abundant < 2 µm size class phytoplankton. Flow cytometry was employed to enumerate picophytoplankton abundances, using their pigments and cell sizes to identify the different groups. The aim of the study was …

Toward an improved understanding of the Southern Ocean's biological pump: phytoplankton group-specific contributions to nitrogen and carbon cycling across the Subantarctic Indian Ocean
… (RA), the open Subantarctic is dominated by picoeukaryotes (64%), although there exists a large disconnect between relative abundance and potential contribution to C export. The three largest surface-ocean phytoplankton populations included in this study – microphytoplankton, cryptophytes, …

Phytoplankton's role in the biological pump during the growth season across the Atlantic Southern Ocean
… groups sorted by flow cytometry (Synechococcus, picoeukaryotes, nanoeukaryotes, and cryptophytes) was measured. Phytoplankton growth fuelled by subsurface nitrate produces particulate organic N (PON) that is high in 15N/14N relative to growth fuelled by ammonium. Using biomass 15N/14N as a …

Resolving the molecular ecology of marine microbial eukaryotes with metatranscriptomes
… transcript abundances. Chapter 3 explores the picoeukaryotes of the dynamic North Pacific Transition Zone, using data from 3 cruises included in the North Pacific Eukaryotic Gene Catalog (Appendix 1). I focus on the small size fraction samples from latitudinal transections of the transition …
