| log in | [Palau Coral Reef Experiment 2018: Pulse Amplitude Modulation (PAM) fluorometry] - Coral pulse amplitude modulation (PAM) fluorometry data from a heating experiment using samples collected from Nikko Bay and Rebotel Reef in Palau in the spring of 2018 (Collaborative Research: Stability, flexibility, and functionality of thermally tolerant coral symbioses) | Coral reefs surrounding Palau, Micronesia are living within a broad range of thermal habitats. Specifically, corals living on the offshore barrier reefs surrounding Palau reside in waters with low temperature variability compared to the much warmer and more acidic waters of near shore environments surrounding the Rock Island habitats. \n\nThis study was designed to test the differences in thermal physiology among two species of reef corals that reside at both of these locations. Specifically, we examined how short-term elevated temperature influences the photochemistry of each coral species from each location before and after heating, as measured by active chlorophyll fluorescence recorded by pulse amplitude modulation (PAM) fluorometry.\n\ncdm_data_type = Other\nVARIABLES:\nLocation_Name (unitless)\nlongitude (degrees_east)\nlatitude (degrees_north)\nSpecies (unitless)\nDate (unitless)\nDay (unitless)\nTreatment (unitless)\nLocation (unitless)\nColony (unitless)\nFrag (unitless)\nSymbiont (unitless)\nFq_Fm (unitless)\nFv_Fm (unitless)\nQm (unitless)\n | BCO-DMO | bcodmo_dataset_855054_v1 | ||||||||||||

For reef-building corals, the benefits of their association with endosymbiotic dinoflagellates differ within and across taxa, and nutrient exchange between these partners is influenced by environmental conditions. Furthermore, it is widely assumed that corals associated with symbionts in the genus Durusdinium tolerate high thermal stress at the expense of lower nutrient exchange to support coral growth. We traced both inorganic carbon (H13CO3–) and nitrate (15NO3–) uptake by divergent symbiont species and quantified nutrient transfer to the host coral under normal temperatures as well as in colonies exposed to high thermal stress. Colonies representative of diverse coral taxa associated with Durusdinium trenchii or Cladocopium spp. exhibited similar nutrient exchange under ambient conditions. In contrast, heat-exposed colonies with D. trenchii experienced less physiological stress than conspecifics with Cladocopium spp. while high carbon assimilation and host transfer was maintained. This discovery is different from the prevailing notion that these mutualisms inevitably suffer trade-offs in physiological performance. These findings emphasize that certain host-symbiont combinations adapted to high temperature equatorial environments; and why their increase in prevalence is likely important to the future productivity and stability of coral reef ecosystems.\n\ncdm_data_type = Other\nVARIABLES:\nlatitude (degrees_north)\nlongitude (degrees_east)\nSite (unitless)\nSpecies (unitless)\nSymbiont (unitless)\nTemperature (degrees Celsius)\nReplicate (unitless)\nFraction (unitless)\nAP13C (percent)\nAP15N (percent)\nFv_Fm (unitless)\nDensities (cells per squared centimeter (cells cm-2))\n | https://erddap.bco-dmo.org/erddap/metadata/fgdc/xml/bcodmo_dataset_907003_v1_fgdc.xml | https://erddap.bco-dmo.org/erddap/metadata/iso19115/xml/bcodmo_dataset_907003_v1_iso19115.xml | https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_907003_v1/index.htmlTable | https://www.bco-dmo.org/dataset/907003
