attribute NC_GLOBAL acquisition_description String [Reference cited below are from Dell et al (2016) Plos One.]  \nStudy site and species:  \n This study was conducted between January and May in 2013 and 2015 on the\ncoral coast of Fiji\\u2019s main island, Viti Levu, in the villages of Votua\nand Vatu-o-lailai (18\\u00b012\\u201932S, 177\\u00b042\\u201900E and\n18\\u00b012\\u201913S, 177\\u00b041\\u201929E respectively; Fig 1). These villages\nare ~3km apart and each has jurisdiction over their stretch of reef flat; a\nhabitat ranging between ~1.5 and 3m deep at high tide and between ~0 and 1.5m\ndeep at low tide. In 2002, these villages established small areas (0.8km2 in\nVotua and 0.5 km2 in Vatu-o-lailai; Fig 1) as no-take MPAs [25]. Though MPA\nand non-MPA areas were initially similar in coral and macroalgal cover (33-42%\nmacroalgal cover; 3-12% coral cover [25]), MPAs now differ significantly from\nthe adjacent non-MPAs in benthic cover and fish diversity and abundance. MPAs\nnow have ~56% live coral cover on hard substrate, ~2% macroalgal cover, ~8\nfold higher biomass of herbivorous fishes, and higher recruitment of both\nfishes and corals than the non-MPAs [5,22]. Meanwhile the non-MPAs have lower\nfish biomass, 5-16% live coral cover on hard substrates and 51-92% macroalgal\ncover, the majority of which is comprised by Phaeophytes (primarily Sargassum\npolycystum C. Agardh [22]). In the MPAs, macroalgal cover is restricted to the\nshallowest, most shoreward areas (where access by herbivorous fishes appears\nlimited), whereas macroalgal cover in the non-MPAs extends throughout the\nhabitat. Thus, over distances of only a few hundred metres, there are dramatic\ndifferences in community composition that may impact the efficacy of factors\ncontrolling macroalgal populations, without the confounding factors of great\ndifferences in space or time.\n \nEffect of habitat and origin on the survival and growth of recruit-sized S.\npolycystum fronds\n \nSmall S. polycystum ramets ~1cm long (range between 0.5cm and 1.5cm) were\ncollected from both the MPA and non-MPA using a nail and hammer so that a\nsmall piece of bedrock remained attached to each alga\\u2019s holdfast,\nallowing four ramets from either the MPA or the non-MPA to be affixed to\n~25cm2 tiles by attaching the rock pieces using aquarium glue (Ecotech Marine,\nUSA). The ramets were selected so that the four on each tile were of equal\norigin and size and were arranged in a square pattern 1cm distance from each\nother. The tiles were placed in coolers, containing a few centimetres of\nseawater and left for 12 hours in the shade to allow the glue to set before\nmoving the tiles to the reef. The tiles were paired so the MPA and non-MPA\nramets were of equal size and one tile of each was affixed in a cage so they\nwere 30cm from each other.\n \nThese cages were either complete, so the ramets would be protected from fish\ngrazing, or open-sided, so the ramets would be exposed to fish grazing. The\nopen cages lacked the 2 walls parallel to the current direction so that fish\naccess was permitted, while cage effects on flow and shading would be as\nsimilar as possible between treatments. The base of each cage was 0.75m x\n0.75m, the height was 0.75m and the mesh size was 1cm2 thus excluding all but\nthe smallest fishes and invertebrates. Ten replicates of each treatment were\ndistributed in Votua\\u2019s MPA and 10 in Votua\\u2019s non-MPA so that the\ncomplete and open cages were paired and the cages in each pair were about one\nmetre apart, while the distance between pairs was \\u2265 two metres. These\ncages were distributed ~25 to 50m from shore at a depth of ~1 to 1.5m at low\ntide.\n \nThe experiment was established mid- January 2013, ran for 4 months (112 days),\nand was checked for ramet mortality every 3 days for the first month and then\nevery week. If an alga was missing but the stone remained, this was noted as\nmortality. If the stone was also missing this could have been due to failure\nof the glue, dislodgement by turbulence, or some unknown agent, so we recorded\nthese as \\u2018lost\\u2019 and excluded them from analysis. Only ten ramets\n(3.1%) were lost which reduced the total number of ramets in the experiment\nfrom 320 to 310.\n \nDespite running for four months and being checked at intervals of 3-7 days\nthroughout this period, we could detect no growth in this experiment so we\nreport only mean duration of survival. Duration of survival was calculated as\nthe average number of days survived by the four MPA ramets and by the four\nnon-MPA ramets in each cage, giving n=10 for each treatment in each habitat.\nDifference scores (mean survival duration for MPA versus non-MPA sub-samples\nin each replicate) were normally distributed (p\\u22650.200; Shapiro-Wilk) so\nthe effect of origin was analysed by paired t-test run separately for each\ntreatment in each location.

attribute NC_GLOBAL project String Killer Seaweeds
attribute NC_GLOBAL projects_0_acronym String Killer Seaweeds
attribute NC_GLOBAL projects_0_description String Extracted from the NSF award abstract:\nCoral reefs are in dramatic global decline, with reefs commonly converting from species-rich and topographically-complex communities dominated by corals to species- poor and topographically-simplified communities dominated by seaweeds. These phase-shifts result in fundamental loss of ecosystem function. Despite debate about whether coral-to-algal transitions are commonly a primary cause, or simply a consequence, of coral mortality, rigorous field investigation of seaweed-coral competition has received limited attention. There is limited information on how the outcome of seaweed-coral competition varies among species or the relative importance of different competitive mechanisms in facilitating seaweed dominance. In an effort to address this topic, the PI will conduct field experiments in the tropical South Pacific (Fiji) to determine the effects of seaweeds on corals when in direct contact, which seaweeds are most damaging to corals, the role allelopathic lipids that are transferred via contact in producing these effects, the identity and surface concentrations of these metabolites, and the dynamic nature of seaweed metabolite production and coral response following contact. The herbivorous fishes most responsible for controlling allelopathic seaweeds will be identified, the roles of seaweed metabolites in allelopathy vs herbivore deterrence will be studied, and the potential for better managing and conserving critical reef herbivores so as to slow or reverse conversion of coral reef to seaweed meadows will be examined.\nPreliminary results indicate that seaweeds may commonly damage corals via lipid- soluble allelochemicals. Such chemically-mediated interactions could kill or damage adult corals and produce the suppression of coral fecundity and recruitment noted by previous investigators and could precipitate positive feedback mechanisms making reef recovery increasingly unlikely as seaweed abundance increases. Chemically-mediated seaweed-coral competition may play a critical role in the degradation of present-day coral reefs. Increasing information on which seaweeds are most aggressive to corals and which herbivores best limit these seaweeds may prove useful in better managing reefs to facilitate resilience and possible recovery despite threats of global-scale stresses. Fiji is well positioned to rapidly use findings from this project for better management of reef resources because it has already erected >260 MPAs, Fijian villagers have already bought-in to the value of MPAs, and the Fiji Locally-Managed Marine Area (FLMMA) Network is well organized to get information to villagers in a culturally sensitive and useful manner.\nThe broader impacts of this project are far reaching. The project provides training opportunities for 2-2.5 Ph.D students and 1 undergraduate student each year in the interdisciplinary areas of marine ecology, marine conservation, and marine chemical ecology. Findings from this project will be immediately integrated into classes at Ga Tech and made available throughout Fiji via a foundation and web site that have already set-up to support marine conservation efforts in Fiji and marine education efforts both within Fiji and internationally. Business and community leaders from Atlanta (via Rotary International Service efforts) have been recruited to help organize and fund community service and outreach projects in Fiji -- several of which are likely to involve marine conservation and education based in part on these efforts there. Media outlets (National Geographic, NPR, Animal Planet, Audubon Magazine, etc.) and local Rotary clubs will be used to better disseminate these discoveries to the public.\nPUBLICATIONS PRODUCED AS A RESULT OF THIS RESEARCH\nRasher DB, Stout EP, Engel S, Kubanek J, and ME Hay. \"Macroalgal terpenes function as allelopathic agents against reef corals\", Proceedings of the National Academy of Sciences, v. 108, 2011, p. 17726.\nBeattie AJ, ME Hay, B Magnusson, R de Nys, J Smeathers, JFV Vincent. \"Ecology and bioprospecting,\" Austral Ecology, v.36, 2011, p. 341.\nRasher DB and ME Hay. \"Seaweed allelopathy degrades the resilience and function of coral reefs,\" Communicative and Integrative Biology, v.3, 2010.\nHay ME, Rasher DB. \"Corals in crisis,\" The Scientist, v.24, 2010, p. 42.\nHay ME and DB Rasher. \"Coral reefs in crisis: reversing the biotic death spiral,\" Faculty 1000 Biology Reports 2010, v.2, 2010.\nRasher DB and ME Hay. \"Chemically rich seaweeds poison corals when not controlled by herbivores\", Proceedings of the National Academy of Sciences, v.107, 2010, p. 9683.
