Survival under conditions of variable food availability: Resource utilization and storage in the cold‐water coral Lophelia pertusa
<p>Abstract</p> <p>Cold-water coral (CWC) reefs are hotspots of biodiversity and productivity in the deep sea, but their distribution is limited by the availability of food, which undergoes complex local and temporal variability. We studied the resource utilization, metabolism, and tissue storage of CWC Lophelia pertusa during an experimentally simulated 3-day food pulse, of 13C15N-enriched phytodetritus, followed by a 4-week food deprivation. Oxygen consumption (0.145 μmol O2 [mmol organic carbon {OC}]−1 h−1), release of particulate organic matter (0.029 μmol particulate organic carbon [POC] [mmol OC]−1 h−1 and 0.005 μmol particulate organic nitrogen [mmol OC]−1 h−1), ammonium excretion (0.004 μmol NH4 + [mmol OC]−1 h−1), tissue C and N content, and fatty acid (FA) and amino acid composition did not change significantly during the experiment. Metabolization of the labeled phytodetritus, however, underwent distinct temporal dynamics. Initially, L. pertusa preferentially used phytodetritus-derived C for respiration (2.2 0.36 nmol C [mmol OC]−1 h−1) and mucus production (0.94 0.52 nmol C [mmol OC]−1 h−1), but those tracer fluxes declined exponentially to <20% within 2 weeks after feeding and then remained stable, indicating that the remainder of the incorporated phytodetritus had entered a tissue pool with lower turnover. Analysis of 13C in individual FAs revealed a mismatch between the FAs incorporated from phytodetritus and the FA requirements of the coral.We suggest that feeding on other resources, such as lipid-rich zooplankton, could fill this deficiency. A release of 10% of their total OC as respired C and POC during the 4-week food deprivation underlines the importance of regular food pulses for CWC reefs. </p>
Terrain- and climate-based habitat suitability indices for the reef-building coral Lophelia pertusa on the Blake Plateau (southeastern United States)
<p>Habitat suitability model outputs from Gasbarro et al. (2022) covering the Blake Plateau region of the southeastern United States margin. These include raster surfaces of ensemble mean, median, and standard deviation habitat suitability indices. Bathymetry-derived terrain variables were used to generate the terrain suitability layers, while climate model outputs were used to generate the climatic suitability layers. Rasters are in WGS84. See Gasbarro et al. (2022) for full modeling details.</p>
