At each site, five 10 m \u00d7 1 m parallel belt transects were set up perpendicular to shore at10 m intervals starting at an arbitrarily selected point. Erythropodium caribaeorum and the encrusting form of Briareum asbestinum were not included in the surveys because they are not branching and, therefore,do not compete for space in the canopy. Each octocoral \u22655 cm in height was identified to species level in the field when possible; otherwise a small, 3 cm long sample was collected from colonies \u226515 cm tall for sclerite examination under a microscope. Images of the colony and a close-up image of the collected branch were also obtained. Identifications were based on Bayer (1961) and S\u00e1nchez (2009). Colonies were divided into 2 classes, those in close proximity to a neighbor, cases in which a colony\u2019s branches or base were within 5 cm of another octocoral colony, and those more distantly spaced. When the branches of 2 colonies are <5 cm apart, branch movement driven by currents and wave action often leads to contacts between the branches. Large colonies whose bases are within 5 cm of each other almost always have branches within 5 cm of each other, and small colonies with bases <5 cm apart at the time of settlement will almost inevitably come into contact with each other as they grow in the canopy. We recorded all instances of interactions. We did not distinguish between interspecific and intraspecific interactions since our goal was to first determine the overall incidence of competition among branching octocorals at the 2 sites. At East Cabritte, which had a greater density of octocorals than Europa Bay, 4 randomly selected 1\u00d71 m2 quadrats on each transect were surveyed while all 10 quadrats on each transect were surveyed atEuropa Bay. The height of each colony was measured to the nearest centimeter. Each colony was assessed for proximity to adjacent colonies and for effects of proximity, tissue damage to branches in close proximity to an adjacent colony and/or an asymmetric colony form. Only the octocorals with an asymmetric colony form attributable to the presence of another octocoral were scored as asymmetric in this study.Colonies that were asymmetric as a result of growing adjacent to a physical obstruction were not included as our focus was on the incidence of competition among octocorals. Examples of the different effects are shown in Fig. 1.

attribute	NC_GLOBAL	projects_0_description	String	Long Term Research in Environmental Biology (LTREB) in US Virgin Islands: From the NSF award abstract: In 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. The 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.

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. This 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.
