attribute	NC_GLOBAL	acquisition_description	String	After completion of fieldwork, a subset of specimens from the transect surveys were chosen for DNA barcoding to confirm or amend field identifications. These specimens included (i) at least one specimen from each field-ID (except obvious species such as Mastigias papua) and (ii) several specimens representing the range of phenotypic variation of field-IDs that showed considerable variation or were challenging to distinguish (e.g. small sponge specimens of similar color and texture). Additionally, specimens from a previously collected voucher collection (indicated with \u201cV_\u201d in prefix of sequence ID) were barcoded and identified by taxonomic experts. Specimens from population genetic collections (indicated with \u201cPG_\u201d in prefix of sequence ID) were also barcoded. DNA was purified using a modified phenol-chloroform CTAB extraction protocol (1) or AcroPrep PALL 5053 glass fiber plates procedure (2, 3). We amplified the Cytochrome c Oxidase subunit I (COI) barcode locus using 0.5 \u00b5L of purified DNA in a 25-\u00b5L polymerase chain reaction (PCR) with 0.05 \u00b5L AMPLITAQ (Applied Biosystems, Foster City, California, USA), 2.5 \u00b5L 10x buffer (Applied Biosystems), 0.63 \u00b5L of 20 \u00b5M primers (Operon Biotechnologies Inc., Huntsville, Alabama, USA), 2.5 \u00b5L of 25 mM MgCl2 (Applied Biosystems), 0.5 \u00b5L of 10 mg/mL bovine serum albumin (BSA) and 0.5 \u00b5L of 10 mM dNTPs. Several primer sets were used (Table 1). Amplicons were sequenced at the University of California Berkeley DNA Sequencing Facility (Berkeley, California, USA). Base calls in electropherograms were visually checked and manually corrected for errors and forward and reverse reads were assembled in Sequencher 4.8 (GeneCodes, Ann Arbor, Michigan, USA). We used Basic Local Alignment Search Tool (BLASTn) to determine the higher level taxonomic assignment for each sequence (which we used to process batches of similar sequences) \u2014 ascidians, bivalves, bryozoans, cnidarians, crustaceans, echinoderms, gastropods, polychaetes, and poriferans. Sequences organized by these broad groups were then aligned using Muscle v3.8.425 (4). For each group, alignments were manually adjusted and trimmed to the same length in Mesquite v3.5 (5) to balance total individuals retained and sequence length. The resulting alignment lengths were: ascidians 395bp, bivalves 567bp, bryozoans 622bp, cnidarians 612bp, crustaceans 299bp, echinoderms 357bp, gastropods 562bp, polychaetes 509bp, and poriferans 688bp. Sequences were translated to amino acid sequence to confirm an open reading frame. Short sequences were excluded from further analysis, but percent pairwise identity with the closest match was recorded for each based on the shortest sequence. Pairwise sequence distance was calculated using dist.dna with Kimura\u2019s 2-parameter distance model of evolution (6) in the ape package v4.1 (7) in R (8). OTUs, or clusters of sequences, similar at 97% were identified using tclust in the spider package v1.5.0 (9) in R (8) for each taxonomic group, except for poriferans, which were clustered at 99% sequence similarity given their slow sequence evolution (10). 1\. \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Dawson MN, Raskoff KA, Jacobs DK (1998) Field preservation of marine invertebrate tissue for DNA analyses.

attribute	NC_GLOBAL	instruments_0_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_description	String	This project will survey the taxonomic, genetic, and functional diversity of the organisms found in marine lakes, and investigate the processes that cause gains and losses in this biodiversity. Marine lakes formed as melting ice sheets raised sea level after the last glacial maximum and flooded hundreds of inland valleys around the world. Inoculated with marine life from the surrounding sea and then isolated to varying degrees for the next 6,000 to 15,000 years, these marine lakes provide multiple, independent examples of how environments and interactions between species can drive extinction and speciation. Researchers will survey the microbes, algae, invertebrates, and fishes present in 40 marine lakes in Palau and Papua, and study how diversity has changed over time by retrieving the remains of organisms preserved in sediments on the lake bottoms. The project will test whether the number of species, the diversity of functional roles played by organisms, and the genetic diversity within species increase and decrease in parallel; whether certain species can greatly curtail diversity by changing the environment; whether the size of a lake determines its biodiversity; and whether the processes that control diversity in marine organisms are similar to those that operate on land. Because biodiversity underlies the ecosystem services on which society depends, society has a great interest in understanding the processes that generate and retain biodiversity in nature. This project will also help conserve areas of economic importance. Marine lakes in the study region are important for tourism, and researchers will work closely with governmental and non-governmental conservation and education groups and with diving and tourism businesses to raise awareness of the value and threats to marine lakes in Indonesia and Palau.
