attribute NC_GLOBAL acquisition_description String Materials and Methods\n \nSampling. Sampling occurred from July 22-24, 2017 and coincided with the\nspring tides. A new moon occurred on July 23 at 5:45 (EST). While St. John\ntidal cycles are typically semidiurnal, during spring tide the tide cycle is\ndiurnal. Sampling time points coincided with the low, flood, high, and ebb\ntides over a 48 hour (hr) window, resulting in 8 total sampling time points.\nSamples were collected \\u00b11 hr from the designated time point, placed on\nice, and processed within two hours of collection. Samples from nine locations\nacross Lameshur Bay and Fish Bay on the south shore of St. John, U.S. Virgin\nIslands represented coral reef, seagrass bed and mangrove biomes. The Lameshur\nBay mangrove location included two distinct sampling sites: an inland area\nthat was only submerged and sampled during high tide and an outlet area that\nwas always submerged and sampled at each time point. The majority of sampling\nsites were within the boundaries of the Virgin Islands National Park, which is\nlargely undeveloped except for a small research station. The Fish Bay\nmangrove, Fish Bay seagrass, and Ditliff reef sites are outside the boundary\nof the park, and the land surrounding Fish Bay is inhabited.\n \nAt all sites, a CTD (Castaway, SonTek, San Diego, CA, USA) was deployed from\nthe surface to the bottom depth in reef and seagrass seawater, and single\npoint measurements were collected from mangrove seawater, to capture the\ntemperature and salinity at each timepoint over the course of the 48 hr\nsampling window. Only temperature and salinity at the surface of the cast was\nused for analysis. Samples for inorganic nutrients were collected by filling\n30ml of surface seawater into acid-washed and seawater-rinsed vials (HDPE,\nNalgene), followed by freezing to 20C. Seawater (875\\u00b5l) was transferred\nto a 2ml cryovial (Corning) for analysis of microbial abundances and fixed to\na final concentration of 1% paraformaldehyde (Electron Microscopy Sciences),\nallowed to fix for 20 min at 4C, then flash-frozen in an LN2 dry shipper. To\ncapture seawater microbial communities, acid-washed 4L bottles (LDPE, Nalgene,\nThermoFisher Scientific, Waltham, MA, USA) were rinsed three times with\nseawater prior to collection of 3L of surface seawater. The specific 4L bottle\nused for a site at the first timepoint remained consistent across all sampling\ntimepoints, and the bottles were rinsed with freshwater between uses.\nFollowing collection, 1L of seawater was pumped using a Masterflex peristaltic\npump (Cole-Palmer, Vernon Hills, IL, USA) through Masterflex silicone tubing\n(L/S, platinum-cured, #96410-24 size, Cole-Parmer) to rinse the tubing. The\nremaining 2L of seawater was filtered through a 0.22\\u00b5m Supor filter\n(25mm; Pall, Ann Arbor, MI, USA). For the mangrove and seagrass sites, 2L\ncould not always be filtered completely and therefore 0.3 - 2L and 1.2 - 2L of\nwater was filtered through the membrane, respectively. For the coral reef\nsites, 1.5 - 2L passed through the filter membrane. All filters were placed\ninto 2ml cryovials (Corning, Corning, NY, USA) and flash-frozen in a liquid\nnitrogen dry shipper until returned to Woods Hole, MA and placed at 80C.\n \nFlow cytometry and Nutrient analyses. Samples for microbial abundance were\nanalyzed at the University of Hawaii with an EPICS Altra flow cytometry\n(Beckman Coulter Life Sciences, Inc, Indianapolis, IN) as described in Furby\net al (Furby et al. 2014), with some modifications. Briefly, to obtain\nconcentrations of cyanobacteria (Prochlorococcus and Synechococcus) and\neukaryotic phytoplankton (picoeukaryotes), an unstained aliquot was run on the\ninstrument and excited by visible wavelengths. To enumerate unpigmented cells,\nwhich is a proxy for heterotrophic bacteria and archaea (Marie et al. 1997),\nan aliquot was stained with a Hoechst DNA stain and run on the flow cytometer\nwith excitation at 488nm. The number of cells per ml was estimated following\nanalysis of fluorescence spectra using FlowJo software (v 6.4.7, Tree Star,\nInc., Ashland, OR, USA).\n \nSamples for nutrient analysis were analyzed at Oregon State University using\nmethods described in Furby et al. (Furby et al. 2014) to measure dissolved\nconcentrations (\\u00b5M) of phosphate, ammonium, nitrite, nitrite + nitrate,\nand silicate.\n \nDNA Extraction, PCR amplification, and Sequencing. DNA was extracted from the\nfilters using a sucrose-EDTA lysis method similar to Santoro et al. (Santoro\net al. 2010) that combines lysis with filter column purification. Briefly, the\n25mm filter was subjected to physical and chemical lysis using 0.1mm glass\nbeads (Lysing Matrix B, MP Biomedicals, Irvine, CA, USA), sucrose-EDTA lysis\nbuffer (0.75M Sucrose, 20mM EDTA, 400mM NaCl, 50 mM Tris) and 10% sodium\ndodecyl sulfate (Teknova, Hollister, CA, USA), followed by a proteinase-K\ndigestion (20 mg/ml Promega, Madison, WI, USA). Lysate was then purified using\nthe DNeasy Blood and Tissue Kit (Qiagen, Germantown, MD, USA) spin column\nfilters. Purified DNA was fluorometrically quantified using a high sensitivity\ndsDNA assay on a Qubit 2.0 fluorometer (ThermoFisher Scientific).\n \nSample DNA was diluted 1:100 in UV-sterilized PCR-grade H2O and 1\\u00b5l was\nused in a PCR reaction. Barcoded primers recommended by the Earth Microbiome\nProject, 515FY and 806RB, were used to amplify the V4 region of the SSU rRNA\ngene in bacteria and archaea (Apprill et al. 2015, Parada et al. 2016).\nTriplicate 25\\u00b5l reactions contained 1.25 units of GoTaq DNA Polymerase\n(Promega, Madison, WI, USA), 0.2\\u00b5M forward and reverse primers, 0.2mM\ndeoxynucleoside triphosphate (dNTP) mix (Promega), 2.5mM MgCl2, 5\\u00b5l GoTaq\n5X colorless flexi buffer (Promega), and nuclease-free water. The reactions\nwere run on a Bio-Rad Thermocycler (Hercules, CA, USA) using the following\ncriteria: denaturation at 95C for 2 min; 28C cycles of 95C for 20 s, 55C for\n15 s, and 72C for 5 min; and extension at 72C for 10 min. Successful\namplification was verified by running 5\\u00b5l of product on a 1% agarose-TBE\ngel stained with SYBR Safe gel stain (Invitrogen, Carlsbad, CA, USA).\nTriplicate PCR products were pooled and purified using the MinElute PCR\npurification kit (Qiagen). Concentration of purified products was quantified\nusing the high sensitivity dsDNA assay on the Qubit 2.0 fluorometer\n(ThermoFisher Scientific). Barcoded PCR products were diluted to equal\nconcentrations and pooled for sequencing. Samples were shipped to the Georgia\nGenomics and Bioinformatics Core at the University of Georgia for sequencing\non an Illumina MiSeq using paired-end 250bp sequencing.\n \nData analysis. All sequence processing and data analysis was performed in R\nStudio (v 1.1.463) running R (v 3.4.0, 2017-04-21). Sequence reads were\ninspected for quality, filtered, trimmed, and dereplicated in the DADA2 R\npackage (v.1.10.0) (Callahan et al. 2016). Specific filtering parameters used\nincluded the following: truncLen = c(240, 200), maxN = 0, maxEE = c(2,2),\nrm.phix = TRUE, and compress = TRUE. DADA2 was then used to generate amplicon\nsequence variants (ASVs) and remove chimeras. Taxonomy was assigned in DADA2\nusing the SILVA SSU rRNA database down to the species level where applicable\n(v.132, (Quast et al. 2012)). ASV counts in each sample were transformed to\nrelative abundance for further data analysis.\n \nTo understand the variability in microbial communities over time at all sites,\nBray-Curtis dissimilarity was calculated between each sample in the R package\nvegan (v2.5.4) (Oksanen et al. 2019) and illustrated using non-metric\nmultidimensional scaling (NMDS) in the R package, ggplot2 (v3.2.1) (Wickham\n2016). Environmental vectors that significantly associated (cutoff p<0.01)\nwith the ordination were produced using the function envfit() in the vegan R\npackage. Pairwise dissimilarity was plotted to represent the range of\ndissimilarity in microbial communities over 48 hrs at each site. A higher\naverage dissimilarity would suggest that the site experiences more variable\nmicrobial communities than a site with a lower average dissimilarity. A\nKruskal-Wallis test was used to examine if there is a significant difference\nbetween sites (significance level p<0.05). To determine which pairs of sites\nhad significantly different dissimilarities, a pairwise Wilcoxon Rank Sum test\nwas used with a Benjamini-Hochberg correction for multiple testing and a\ncutoff of 0.05.\n \nDifferential abundance (DA) and of ASVs in relation to the tide was evaluated\nat mangrove sites using the corncob R package (v0.1.0) (Martin et al. 2019).\nThe following analyses were conducted on a subset of the data representing\nmangrove communities. All ASV relative abundances were modeled in corncob\nusing a logit-link for mean and dispersion. DA was modeled as a linear\nfunction of sea level (a continuous covariate that is representative of the\ntide cycle) while controlling for differential variance and the effect of site\nand day or night on DA. Controlling for the effect of day or night was\nimperative because over the 48 hr period low and flood tide only occurred\nduring the day and high and low tide only occurred during dusk and night,\nrespectively. The parametric Wald test was used to test the hypotheses that\nthe relative abundance or variance of a given ASV changed significantly with\nrespect to sea level and the Benjamini-Hochberg false discovery rate (FDR)\ncorrection was applied to account for multiple comparisons, with the cutoff at\n0.05.

attribute NC_GLOBAL instruments_2_description String General term for a laboratory instrument used for deciphering the order of bases in a strand of DNA. Sanger sequencers detect fluorescence from different dyes that are used to identify the A, C, G, and T extension reactions. Contemporary or Pyrosequencer methods are based on detecting the activity of DNA polymerase (a DNA synthesizing enzyme) with another chemoluminescent enzyme. Essentially, the method allows sequencing of a single strand of DNA by synthesizing the complementary strand along it, one base pair at a time, and detecting which base was actually added at each step.

attribute NC_GLOBAL projects_0_acronym String Coral Exometabolomes
attribute NC_GLOBAL projects_0_description String NSF abstract:\nCoral reefs are some of the most diverse and productive ecosystems in the ocean. Globally, reefs have declined in stony (reef-building) coral abundance due to environmental variations, and in the Caribbean this decline has coincided with an increase in octocoral (soft coral) abundance. This phase shift occurring on Caribbean reefs may be impacting the interactions between the sea floor and water column and particularly between corals and picoplankton. Picoplankton are the microorganisms in the water column that utilize organic matter released from corals to support their growth. These coral-picoplankton interactions are relatively unstudied, but could have major implications for reef ecology and coral health. This project will take place in the U.S. territory of the Virgin Islands (USVI) and will produce the first detailed knowledge about the chemical diversity and composition of organic matter released from diverse stony coral and octocoral species. This project will advance our understanding of coral reef microbial ecology by allowing us to understand how different coral metabolites impact picoplankton growth and dynamics over time. The results from this project will be made publically accessible in a freely available online magazine, and USVI minority middle and high school students will be exposed to a lesson about chemical-biological interactions on coral reefs through established summer camps. This project will also contribute to the training of USVI minority undergraduates as well as a graduate student.\nCoral exometabolomes, which are the sum of metabolic products of the coral together with its microbiome, are thought to structure picoplankton communities in a species-specific manner. However, a detailed understanding of coral exometabolomes, and their influences on reef picoplankton, has not yet been obtained. This project will utilize controlled aquaria-based experiments with stony corals and octocorals, foundational species of Caribbean reef ecosystems, to examine how the exometabolomes of diverse coral species differentially influence the reef picoplankton community. Specifically, this project will capitalize on recent developments in mass spectrometry-based metabolomics to define the signature exometabolomes of ecologically important and diverse stony corals and octocorals. Secondly, this project will determine how the exometabolomes of these corals vary with factors linked to coral taxonomy as well as the coral-associated microbiome (Symbiodinium algae, bacteria and archaea). With this new understanding of coral exometabolomes, the project will then apply a stable isotope probe labeling approach to the coral exometabolome and will examine if and how (through changes in growth and activity) the seawater picoplankton community incorporates coral exometabolomes from different coral species over time. This project will advance our ability to evaluate the role that coral exometabolomes play in contributing to benthic-picoplankton interactions on changing Caribbean reefs.
