Sampling and analytical procedures: Surveys were completed at six sites on shallow (7–9-m depth) fringing reefs on the south shore of St. John, between Cabritte Horn and White Point. In 1992, these sites were randomly selected on hard substrata along 4.5 km of shore between these headlands, and they have been censused annually to present. Each site consists of a permanently marked transect that has been 40-m long since 2000. The present project began in 2014 with the objective of augmenting a long-standing analysis of benthic community structure (which emphasized scleractinians with new analyses focused on octocorals. As part of this effort, arborescent octocorals were surveyed in situ with genus resolution, using 40 quadrats (0.5 × 0.5 m) placed at random, non-overlapping positions along the same transect (and re-randomized annually) located at each of the six sites. Surveys were completed over four weeks beginning on ~ 20th July of each of 2014–2017, and were conducted by counting and measuring the height of octocorals attached by holdfasts within each quadrat. Height was determined (± 1 cm) using a flexible tape measure stretched from the holdfast to the colony apex. Abundances were analyzed separately for adults (&gt; 5-cm tall), and recruits (≤ 5-cm tall), with this size cut-off based on the maximal height to which the recruits of most octocoral species are likely to grow in one year. While the benthos was inspected for all small octocorals, sampling efficiency probably was low for recruits consisting of only a few polyps (i.e., &lt; 1-cm tall). Analyses testing for the effects of density dependence (DD) and self-thinning (ST) were first, completed for octocorals pooled among taxa, and second, for the three most common genera of octocorals. Evidence of DD recruitment also was sought from analyses of per capita recruitment by site, with these values obtained by dividing the density of recruits by mean density of adults.

Collaborative Research: Pattern and process in the abundance and recruitment of Caribbean octocorals https://osprey.bco-dmo.org/project/752508 Collaborative Research: Pattern and process in the abundance and recruitment of Caribbean octocorals <p><em>NSF Award Abstract:</em><br /> Coral reefs are exposed to a diversity of natural and anthropogenic disturbances, and the consequences for ecosystem degradation have been widely publicized. However, the reported changes have been biased towards fishes and stony corals, and for Caribbean reefs, the most notable example of this bias are octocorals ("soft corals"). Although they are abundant and dominate many Caribbean reefs, they are rarely included in studies due to the difficulty of both identifying them and in quantifying their abundances. In some places there is compelling evidence that soft corals have increased in abundance, even while stony corals have become less common. This suggests that soft corals are more resilient than stony corals to the wide diversity of disturbances that have been impacting coral corals. The best coral reefs on which to study these changes are those that have been studied for decades and can provide a decadal context to more recent events, and in this regard the reefs of St. John, US Virgin Islands are unique. Stony corals on the reefs have been studied since 1987, and the soft corals from 2014. This provides unrivalled platform to evaluate patterns of octocoral abundance and recruitment; identify the patterns of change that are occurring on these reefs, and identify the processes responsible for the resilience of octocoral populations. The project will extend soft coral monitoring from 4 years to 8 years, and within this framework will examine the roles of baby corals, and their response to seafloor roughness, seawater flow, and seaweed, in determining the success of soft corals. The work will also assess whether the destructive effects of Hurricanes Irma and Maria have modified the pattern of change. In concert with these efforts the project will be closely integrated with local high schools at which the investigators will host marine biology clubs and provide independent study opportunities for their students and teachers. Unique training opportunities will be provided to undergraduate and graduate students, as well as a postdoctoral researcher, all of whom will study and work in St. John, and the investigators will train coral reef researchers to identify the species of soft corals through a hands-on workshop to be conducted in the Florida Keys.</p> <p>Understanding how changing environmental conditions will affect the community structure of major biomes is the ecological objective defining the 21st century. The holistic effects of these conditions on coral reefs will be studied on shallow reefs within the Virgin Islands National Park in St. John, US Virgin Islands, which is the site of one of the longest-running, long-term studies of coral reef community dynamics in the region. With NSF-LTREB support, the investigators have been studying long-term changes in stony coral communities in this location since 1987, and in 2014 NSF-OCE support was used to build an octocoral "overlay" to this decadal perspective. The present project extends from this unique history, which has been punctuated by the effects of Hurricanes Irma and Maria, to place octocoral synecology in a decadal context, and the investigators exploit a rich suite of legacy data to better understand the present and immediate future of Caribbean coral reefs. This four-year project will advance on two concurrent fronts: first, to extend time-series analyses of octocoral communities from four to eight years to characterize the pattern and pace of change in community structure, and second, to conduct a program of hypothesis-driven experiments focused on octocoral settlement that will uncover the mechanisms allowing octocorals to more effectively colonize substrata than scleractinian corals on present day reefs. Specifically, the investigators will conduct mensurative and manipulative experiments addressing four hypotheses focusing on the roles of: (1) habitat complexity in distinguishing between octocoral and scleractinian recruitment niches, (2) the recruitment niche in mediating post-settlement success, (3) competition in algal turf and macroalgae in determining the success of octocoral and scleractian recruits, and (4) role of octocoral canopies in modulating the flux of particles and larvae to the seafloor beneath. The results of this study will be integrated to evaluate the factors driving higher ecological resilience of octocorals versus scleractinians on present-day Caribbean reefs.</p> <p>This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.</p> Octocoral Community Dynamics largerWorkCitation project eng; USA oceans -64.723 -64.723 18.32 18.32 2014-01-01 2017-01-01 St. John, US Virgin Islands 0 BCO-DMO catalogue of parameters from Octocoral colony height by pooled pooled taxa and year from surveys conducted in St. John, US Virgin Islands from 2014 to 2017 Biological and Chemical Oceanography Data Management Office (BCO-DMO) Unavailable 508-289-2009 WHOI MS#36 Woods Hole MA 02543 USA info@bco-dmo.org http://www.bco-dmo.org Monday - Friday 8:00am - 5:00pm For questions regarding this resource, please contact BCO-DMO via the email address provided. pointOfContact http://lod.bco-dmo.org/id/dataset-parameter/789274.rdf Name: Year Units: unitless Description: <p>Year (2014, 2015, 2016, 2017)</p> http://lod.bco-dmo.org/id/dataset-parameter/789275.rdf Name: Taxon Units: unitless Description: <p>Taxon (All Taxa, Eunicea, Gorgonia, Antillogorgia)</p> http://lod.bco-dmo.org/id/dataset-parameter/789276.rdf Name: Site Units: unitless Description: <p>Site (Cabritte Horn, Europa Bay, West Tektite, East Tektite, White Point, West Little Lameshur)</p> http://lod.bco-dmo.org/id/dataset-parameter/789277.rdf Name: Life_stage Units: unitless Description: <p>Life stage (adult or Juvenile)</p> http://lod.bco-dmo.org/id/dataset-parameter/789278.rdf Name: Height Units: centimeters (cm) Description: <p>Colony height</p> GB/NERC/BODC > British Oceanographic Data Centre, Natural Environment Research Council, United Kingdom Biological and Chemical Oceanography Data Management Office (BCO-DMO) Unavailable 508-289-2009 WHOI MS#36 Woods Hole MA 02543 USA info@bco-dmo.org http://www.bco-dmo.org Monday - Friday 8:00am - 5:00pm For questions regarding this resource, please contact BCO-DMO via the email address provided. pointOfContact 81306 https://darchive.mblwhoilibrary.org/bitstream/1912/25384/1/dataset-789149_edmunds-and-lasker-meps-2019-fig-2b-height-taxon-and-year__v1.tsv download https://doi.org/10.1575/1912/bco-dmo.789149.1 download onLine dataset The following methodology applies to this dataset in addition to other datasets published in Edmunds and Lasker (2019).
