attribute NC_GLOBAL acquisition_description String Sampling and analytical procedures:  \n Clear Lake sediments were extracted using a Dionex Accelerated Solvent\nExtractor (ASE 200), and the resulting total lipid extract was separated into\nneutral and polar fractions using column chromatography with aminopropyl gel\nas the stationary phase. The neutral fraction was then separated into\nhydrocarbon, wax ester, sterol and polar fractions via a silica gel column\nchromatography. Dinosterol was isolated then from the sterol fraction via\nreverse phase (RP)- high-performance liquid chromatography (HPLC)\\u2028.\n \nInstruments:  \n Dinosterol was isolated from the sterol fraction via reverse phase (RP)-\nhigh performance liquid chromatography (HPLC). An Agilent 1100 HPLC with an\nintegrated autoinjector, quaternary pump, and fraction collector was coupled\nto an Agilent 1100 LC/MSD SL mass spectrometer with a multimode source that\nwas operated in positive atmospheric pressure chemical ionization (APCI+)\nmode. The HPLC method used is outlined in Nelson and Sachs\n(2013).\\u00a0Subsequently to HPLC separation the fraction containing\ndinosterol was analyzed via GC-MSD to verify sufficient baseline separation.\nAdjacent HPLC fractions were also analyzed to ensure that no dinosterol eluted\ninto those fractions.\n \nAfter the dinosterol was sufficiently isolated from co-eluting compounds, the\nsample was injected onto a GC-irms for determination of the d2H of\ndinosterol.\\u00a0 Hydrogen isotope determinations were made using a Finnigan\nDelta V Plus Isotope Ratio Mass Spectrometer (irMS) coupled to a Thermo Trace\nGC Ultra with a Varian VF-17ms FactorFour capillary column (60 m x 0.32 mm x\n0.25 m) and a pyrolysis reactor. Samples were injected into a split/splitless\ninlet in splitless mode at 310 C. The oven temperature was ramped from 100 C\nto 220 C at a rate of 20 C/min, then at 2 C /min up to 325 C where it was held\nfor 17 min. The carrier gas, He, was held constant at 2.6 mL/min. The\npyroloysis reactor was maintained at 1400 C. Isotope values, expressed as D\nvalues, were calculated in Isodat software relative to VSMOW using a co-\ninjection standard containing nC28 nC32, nC40, and nC44 of known \\u22022H\nvalues (obtained from Arndt Schimmelmann, Indiana University, Bloomington, IN,\nUSA). The measured isotope values of dinosterol were corrected for the\naddition of hydrogen atoms (of known D value) that occurred during\nacetylation. Each sample was analyzed in at least duplicate, and error bars\nrepresent standard deviations of replicate measurements.

attribute NC_GLOBAL instruments_1_description String A High-performance liquid chromatograph (HPLC) is a type of liquid chromatography used to separate compounds that are dissolved in solution. HPLC instruments consist of a reservoir of the mobile phase, a pump, an injector, a separation column, and a detector. Compounds are separated by high pressure pumping of the sample mixture onto a column packed with microspheres coated with the stationary phase. The different components in the mixture pass through the column at different rates due to differences in their partitioning behavior between the mobile liquid phase and the stationary phase.

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.\nBecause 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.
