attribute NC_GLOBAL acquisition_description String Methodology\\u00a0from\\u00a0Gambrel, B.\\u00a0and\\u00a0Lasker, H.R., 2016\n \nTo further examine the spatial distribution of colonies and potential\ncompetition among them,\\u00a0nearest neighbor data\\u00a0were collected along\nthe belt\\u00a0transects from\\u00a0each site. Each transect had 20\nsampling\\u00a0points arranged\\u00a0at the corners of every 1 m2\nquadrat\\u00a0along the\\u00a0first 9 m of each transect. The\noctocoral\\u00a0colony closest\\u00a0to each sampling point was selected,\nidentified,and the distance between its base and the\\u00a0base of\\u00a0its\nnearest branching octocoral neighbor\\u00a0was measured\\u00a0to the nearest\ncentimeter (Fig. S1\\u00a0in the\\u00a0Supplement). The height, width, and\nlength\\u00a0of each\\u00a0colony was measured to the nearest\\u00a0centimeter\nto\\u00a0calculate\\u00a0cross-sectional\\u00a0area (height \\u00d7\nlength)\\u00a0and volume\\u00a0(height \\u00d7 width \\u00d7 length), and\nthe\\u00a0proximity of\\u00a0the colony\\u2019s branches to nearby\noctocorals\\u00a0was also\\u00a0noted. Due to the water flow and\nthe\\u00a0resulting oscillation\\u00a0of colony branches, measurements\\u00a0were\nmade\\u00a0when the branches were vertical in the\\u00a0water column\\u00a0to\noptimize the precision of our measurements.To increase sample sizes, an\nadditional 9\\u00a0m transect\\u00a0parallel to the other 5 was sampled\nat\\u00a0each site.\n \nThe nature of the spatial distribution of\\u00a0octocorals at\\u00a0each site\nwas determined from the nearest-neighbor data\\u00a0following Clark & Evans\n(1954).\\u00a0Observed and\\u00a0expected mean distances between\nthe\\u00a0octocoral neighbors\\u00a0were calculated using the\ntotal\\u00a0distance between\\u00a0neighbors, sample size (120 pairs\nof\\u00a0octocorals per\\u00a0site) and the density of octocorals at each\nsite(calculated from the belt transect data). The ratio (R)of the observed and\nexpected (given a randomly\\u00a0distributed octocoral\\u00a0community) mean\ndistances between octocoral neighbors describes the\\u00a0octocoral\ndistribution\\u00a0at each site, where R = 1 denotes a\\u00a0random\ndistribution, R < 1, an aggregated distribution,and R > 1, a uniform\ndistribution (Clark & Evans1954). The significance of R was determined\nby\\u00a0analyzing the\\u00a0standard variate of the normal curve (c), since the\nmeasured distances between neighbors in\\u00a0a randomly\\u00a0dispersed\ncommunity are expected to\\u00a0follow a\\u00a0normal distribution.\n \nThe effects of colony\\u2212colony proximity on colony size were assessed by\ncorrelating the distance\\u00a0between\\u00a0neighbors at the base with the sum\nof\\u00a0their sizes\\u00a0(Pielou 1962). If competition affects growth, then\nthe closer\\u00a0the organisms\\u00a0are, the smaller their expected sizes will\nbe (Pielou 1962). Implicit in these analyses is the notion that size is both\nan indicator of resource use and of success in acquiring resources.\n \nThe relationships among the distance between octocoral neighbors at the base\n(divided into 3 distance groups to make the data categorical: 5\\u221214 cm,\n15\\u221224\\u00a0cm\\u00a0and 25\\u221234 cm), branch proximity and site were\nanalyzed using a hierarchical log-linear test in SPSS. The relationship\nbetween the distance between neighbors and branch proximity was further\nanalyzed in a separate log-linear test in SPSS.

attribute NC_GLOBAL projects_0_description String Long Term Research in Environmental Biology (LTREB) in US Virgin Islands:\nFrom the NSF award abstract:\nIn an era of growing human pressures on natural resources, there is a critical need to understand how major ecosystems will respond, the extent to which resource management can lessen the implications of these responses, and the likely state of these ecosystems in the future. Time-series analyses of community structure provide a vital tool in meeting these needs and promise a profound understanding of community change. This study focuses on coral reef ecosystems; an existing time-series analysis of the coral community structure on the reefs of St. John, US Virgin Islands, will be expanded to 27 years of continuous data in annual increments. Expansion of the core time-series data will be used to address five questions: (1) To what extent is the ecology at a small spatial scale (1-2 km) representative of regional scale events (10's of km)? (2) What are the effects of declining coral cover in modifying the genetic population structure of the coral host and its algal symbionts? (3) What are the roles of pre- versus post-settlement events in determining the population dynamics of small corals? (4) What role do physical forcing agents (other than temperature) play in driving the population dynamics of juvenile corals? and (5) How are populations of other, non-coral invertebrates responding to decadal-scale declines in coral cover? Ecological methods identical to those used over the last two decades will be supplemented by molecular genetic tools to understand the extent to which declining coral cover is affecting the genetic diversity of the corals remaining. An information management program will be implemented to create broad access by the scientific community to the entire data set.\nThe importance of this study lies in the extreme longevity of the data describing coral reefs in a unique ecological context, and the immense potential that these data possess for understanding both the patterns of comprehensive community change (i.e., involving corals, other invertebrates, and genetic diversity), and the processes driving them. Importantly, as this project is closely integrated with resource management within the VI National Park, as well as larger efforts to study coral reefs in the US through the NSF Moorea Coral Reef LTER, it has a strong potential to have scientific and management implications that extend further than the location of the study.\nThe following publications and data resulted from this project:\n2015    Edmunds PJ, Tsounis G, Lasker HR (2015) Differential distribution of octocorals and scleractinians around St. John and St. Thomas, US Virgin Islands.

attribute NC_GLOBAL projects_1_description String The recent past has not been good for coral reefs, and journals have been filled with examples of declining coral cover, crashing fish populations, rising cover of macroalgae, and a future potentially filled with slime. However, reefs are more than the corals and fishes for which they are known best, and their biodiversity is affected strongly by other groups of organisms. The non-coral fauna of reefs is being neglected in the rush to evaluate the loss of corals and fishes, and this project will add on to an on-going long term ecological study by studying soft corals. This project will be focused on the ecology of soft corals on reefs in St. John, USVI to understand the Past, Present and the Future community structure of soft corals in a changing world. For the Past, the principal investigators will complete a retrospective analysis of octocoral abundance in St. John between 1992 and the present, as well as Caribbean-wide since the 1960's. For the Present, they will: (i) evaluate spatio-temporal changes between soft corals and corals, (ii) test for the role of competition with macroalgae and between soft corals and corals as processes driving the rising abundance of soft corals, and (iii) explore the role of soft corals as \"animal forests\" in modifying physical conditions beneath their canopy, thereby modulating recruitment dynamics. For the Future the project will conduct demographic analyses on key soft corals to evaluate annual variation in population processes and project populations into a future impacted by global climate change.\nThis project was funded to provide and independent \"overlay\" to the ongoing LTREB award (DEB-1350146, co-funded by OCE, PI Edmunds) focused on the long-term dynamics of coral reefs in St. John.\nNote: This project is closely associated with the project \"RAPID: Resilience of Caribbean octocorals following Hurricanes Irma and Maria\".
