  • Dataset
    Untargeted metabolomic data collected during a thermal stress experiment using reef building corals collected in Kāne'ohe Bay, O'ahu, Hawai'i.

    Understanding the response of the coral holobiont to environmental change is crucial to inform conservation efforts. The most pressing problem is “coral bleaching,” usually precipitated by prolonged thermal stress. We used untargeted, polar metabolite profiling to investigate the physiological response of the coral species Montipora capitata and Pocillopora acuta to heat stress. Our goal was to identify diagnostic markers present early in the bleaching response. From the untargeted UHPLC-MS data, a variety of co-regulated dipeptides were found that have the highest differential accumulation in both species. The structures of four dipeptides were determined and showed differential accumulation in symbiotic and aposymbiotic (alga-free) populations of the sea anemone Aiptasia (Exaiptasia pallida), suggesting the deep evolutionary origins of these dipeptides and their involvement in symbiosis. These and other metabolites may be used as diagnostic markers for thermal stress in wild coral.

    Experimental tank conditions through the four day acclimation period and five week thermal stress experiment. Temperature in each tank was logged every 10 minutes as well as discrete measurements of temperature, pH, salinity, and conductivity made twice daily. Flow rates of each tank were measured once a day, and light (PAR) was measured once daily in the morning.   For a complete list of measurements, refer to the full dataset description in the supplemental file 'Dataset_description.pdf'.

    Two common reef-building corals, Montipora capitata and Pocillopora acuta, were collected from six sites in Kāne'ohe Bay, O'ahu, Hawai'i. Fragments were allowed to acclimate in experimental tanks for two weeks prior to exposure to one of the following four treatments: Ambient Temperature Ambient pCO2 (ATAC), Ambient Temperature High pCO2 (ATHC), High Temperature Ambient pCO2 (HTAC), and High Temperature High pCO2 (HTHC). The treatment period lasted for a two month period, starting on September 22nd, 2018 and lasting through November 17th, 2018. Following the stress period, coral fragments were exposed to a two-month recovery period in ambient conditions.  Survivorship was tracked every day and analyzed for survivorship probability. This dataset includes the raw data of tracked survivorship.  For a complete list of measurements, refer to the full dataset description in the supplemental file 'Dataset_description.pdf'.

The treatment period lasted for a two month period, starting on September 22nd, 2018 and lasting through November 17th, 2018. Following the stress period, coral fragments were exposed to a two-month recovery period in ambient conditions. Throughout the entire four-month experiment, fragments were randomly sampled from each tank and treatment for the following physiology parameters: gross photosynthesis, respiration, net photosynthesis (gross photosynthesis - respiration), photosynthesis:respiration ratio, chlorophyll concentration (pigment a and c2), symbiont and host tissue biomass, symbiont:host tissue biomass ratio, host soluble protein, host total antioxidant capacity, and endosymbiont density. Net photosynthesis, chlorophyll concentration, and symbiont tissue biomass were normalized to host surface area (cm-2) and endosymbiont density (cell-1).   For a complete list of measurements, refer to the full dataset description in the supplemental file 'Dataset_description.pdf'.

    M. capitata was exposed to thermal stress during its spawning cycle over the course of 5 weeks, during which polar metabolomic data were collected. We analyzed these data streams individually, and then integrated both data sets using MAGI (Metabolite Annotation and Gene Integration) to investigate molecular transitions and biochemical reactions.
