    Isotopic analysis of ¹³C and ¹⁵N for sponges, coral, and zooxanthellae (family Symbiodiniaceae) used in a 'pulse-chase' experiment to examine the uptake of sponge-derived nutrients by the coral holobiont
    (Biological and Chemical Oceanography Data Management Office (BCO-DMO). Contact: bco-dmo-data@whoi.edu, 2023-02-24) Reigel, Alicia M. ; Easson, Cole G. ; Apprill, Amy ; Freeman, Christopher J. ; Bartley, Michaela M. ; Fiore, Cara L.
    These are raw data from isotopic analysis of ¹³C and ¹⁵N for sponges, coral, and zooxanthellae (family Symbiodiniaceae) used in a 'pulse-chase' experiment to examine the uptake of sponge-derived nutrients by the coral holobiont. Coral were collected from the Florida Keys National Marine Sanctuary and the experiments were carried out at the Climate and Acidification Ocean Simulator (CAOS) at Mote Marine Laboratory at Summerland Key, Florida, USA.

    A phosphate starvation response gene (psr1-like) is present and expressed in Micromonas pusilla and other marine algae
    (Inter Research, 2021-02-25) Fiore, Cara L. ; Alexander, Harriet ; Kido Soule, Melissa C. ; Kujawinski, Elizabeth B.
    Phosphorus (P) limits primary production in regions of the surface ocean, and many plankton species exhibit specific physiological responses to P deficiency. The metabolic response of Micromonas pusilla, an ecologically relevant marine photoautotroph, to P deficiency was investigated using metabolomics and comparative genomics. The concentrations of some intracellular metabolites were elevated in the P-deficient cells (e.g. xanthine, inosine), and genes involved in the associated metabolic pathways shared a predicted conserved amino acid motif in the non-coding regions of each gene. The presence of the conserved motif suggests that these genes may be co-regulated, and the motif may constitute a regulatory element for binding a transcription factor, specifically that of Psr1 (phosphate starvation response). A putative phosphate starvation response gene ( psr1-like) was identified in M. pusilla with homology to well characterized psr1/ phr1 genes in algae and plants, respectively. This gene appears to be present and expressed in other marine algal taxa (e.g. Emiliania huxleyi) in field sites that are chronically P limited. Results from the present study have implications for understanding phytoplankton taxon-specific roles in mediating P cycling in the ocean.

    Coral fragment surface area calculations utilizing two methods (tin foil and Image J) and corresponding zooxanthellae count data
    (Biological and Chemical Oceanography Data Management Office (BCO-DMO). Contact: bco-dmo-data@whoi.edu, 2022-10-03) Reigel, Alicia M. ; Easson, Cole G. ; Apprill, Amy ; Freeman, Christopher J. ; Bartley, Michaela M. ; Fiore, Cara L.
    This dataset presents coral fragment surface area calculations utilizing two methods (tin foil and Image J) and corresponding zooxanthellae count data. Three coral species were utilized in this experiment: the octocoral, Eunicea flexuosa, and two hard coral species, Acropora cervicornis and Orbicella faveolata. For a complete list of measurements, refer to the full dataset description in the supplemental file 'Dataset_description.pdf'.
