For example, variation in the abundance, diversity, and community composition of microbiomes across host species may drive niche partitioning due to differential assimilation and recycling of nutrients across sponge species. Stable isotope analysis of bulk sponge tissue allowed us to test for evidence of partitioning of three major resource pools (dissolved organic matter: DOM, particulate organic matter: POM, and inorganic nutrients: NaHCO3 and NaNO3) among four emergent Caribbean sponge species. Results from bulk (holobiont tissue including both sponge and microbial cells) stable isotope analysis show niche partitioning, with strong interspecific variation in the relative exploitation of each resource pool. These results demonstrate that associations with microbial symbionts have facilitated niche partitioning by allowing host sponges to acquire and recycle diverse nutrient pools via unique mechanisms.\n\ncdm_data_type = Other\nVARIABLES:\nExperiment (unitless)\ntime_sample (Time, unitless)\nreplicate (unitless)\nspecies_abbreviation (unitless)\nSpecies_name (unitless)\nCollection_date (unitless)\nlatitude (degrees_north)\nlongitude (degrees_east)\nLinear_corr_d15N (permille (‰))\nwt_perc_N (percentag (%))\nAtm_perc_15N (percentag (%))\nLinear_corr_d13C (permille (‰))\nwt_perc_C (percentag (%))\nAtm_perc_13C (percentag (%))\n | https://erddap.bco-dmo.org/erddap/metadata/fgdc/xml/bcodmo_dataset_954470_v1_fgdc.xml | https://erddap.bco-dmo.org/erddap/metadata/iso19115/xml/bcodmo_dataset_954470_v1_iso19115.xml | https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_954470_v1/index.htmlTable | https://osprey.bco-dmo.org/dataset/954470

(Collaborative Research: Investigations into microbially mediated ecological diversification in sponges) | Marine sponges host diverse communities of microbial symbionts that expand the metabolic capabilities of their host, but the abundance and structure of these communities is highly variable across sponge species. Specificity in these interactions may fuel host niche partitioning on crowded coral reefs by allowing individual sponge species to exploit unique sources of carbon and nitrogen, but this hypothesis is yet to be tested. Given the presence of high sponge biomass and the coexistence of diverse sponge species, the Caribbean Sea provides a unique system in which to investigate this hypothesis. To test for ecological divergence among sympatric Caribbean sponges and investigate whether these trends are mediated by microbial symbionts, we measured stable isotope (δ13C and δ15N) ratios and characterized the microbial community structure of sponge species at sites within four regions spanning a 1700 km latitudinal gradient. Samples were collected in 2013 and 2014 from reefs in Honduras, Belize, Panama, and the Florida Keys. There was a low (median of 8.2 %) overlap in the isotopic niches of sympatric species; in addition, host identity accounted for over 75% of the dissimilarity in both δ13C and δ15N values and microbiome community structure among individual samples within a site. There was also a strong phylogenetic signal in both δ15N values and microbial community diversity across host phylogeny, as well as a correlation between microbial community structure and variation in δ13C and δ15N values across samples. Together, this evidence supports a hypothesis of strong evolutionary selection for ecological divergence across sponge lineages and suggests that this divergence is at least partially mediated by associations with microbial symbionts.\n\ncdm_data_type = Other\nVARIABLES:\nSpecies_name (unitless)\nRegion_Country (unitless)\nlatitude (degrees_north)\nlongitude (degrees_east)\nMonth_and_year_of_collection (unitless)\nAve_depth_ft (feet)\nFreeman_Mean_Chla_Dry_wt (micrograms of chlorophyll a per gram of sponge tissue)\nHL_Chla (unitless)\nHMA_LMA (unitless)\n...
