Project description:We subjected three inshore and four offshore genotypes of the coral Orbicella faveolata to 30, 31, 32, or 33ºC for 31 days and measured photochemical efficiency (Fv/Fm), the types and relative abundance of dinoflagellate endosymbionts, and gene expression of the host and symbiont. All inshore coral genotypes, regardless of symbiont type, were significantly more thermotolerant than offshore genotypes based on declines in Fv/Fm. The most heat-tolerant inshore genotype (In1) was dominated by Durusdinium trenchii; all other genotypes were Breviolum-dominated, suggesting local adaptation or acclimatization contributes to the heat tolerance of inshore genotypes. After 31 days of heat stress, all coral genotypes (except In2) had lost most of their Breviolum and became dominated by D. trenchii. Host genotype In1 presented unique expression patterns of genes involved in heat shock response, immunity, and protein degradation. There were few changes in the symbiont transcriptomes of inshore corals under heat stress, but significant changes in symbiont gene expression from the offshore colonies, including increases in ribosomal and photosynthetic proteins. These data show that the differential thermotolerance between inshore and offshore O. faveolata in the Florida Keys is associated with statistically significant differences in both host and symbiont gene expression that provide insights into the mechanisms underlying holobiont heat tolerance.

Project description:<p>Sponges are sessile filter-feeders that can process vast amounts of water and are known to influence the chemistry of the surrounding seawater. There has been limited work however to understand the extent to which sponges alter dissolved organic matter (DOM), yet in areas where sponges are abundant, sponges may contribute significantly to the reef seawater profile of DOM. This work provides an in-depth examination of six prevalent sponges on Caribbean reefs and how they alter DOM and other seawater nutrients. Incurrent and excurrent seawater samples were collected for each of the six sponge species and processed for: inorganic nutrients, fluorescent dissolved organic matter (fDOM), untargeted and targeted metabolomics, and particulate matter by flow cytometry. Sponges were sampled from two coral reef sites in the Florida Keys (Florida, USA): Looe Key reef and Wonderland reef in the southern Florida Keys. We found higher that sponges altered a relatively small subset of the DOM profile and were a net sink of most mass features from untargeted metabolomics. However, sponges also released some putatively labile metabolites and processed DOM in a species-specific manner. These results provide additional support for the large impact that sponges have in the dissolved nutrient profile on coral reefs and provide support for a species-specific impact, with some species altering the DOM profile, fDOM profile, and/or inorganic nutrients to a greater extent than other species. These results have implications for better understanding the influence of the sponge community on coral reef nutrient dynamics.</p>
