attribute NC_GLOBAL acquisition_description String For complete methodology, see Ramus et al., 2017\n(doi:[10.1073/pnas.1700353114](\\\\\"https://dx.doi.org/10.1073/pnas.1700353114\\\\\")).\nIn summary:  \n The experiment was carried out on intertidal mud and sandflats located\nwithin the Zeke\\u2019s Island National Estuarine Research Reserve (33.95 N,\n77.94 W), North Carolina, USA. We manipulated six densities (n = 8 per\ntreatment) of the nonnative seaweed Gracilaria vermiculophylla in 48 large 25\nsquare meter\\u00a0plots over a 10-month period. We selected three low-\nintertidal flats spanning over 1 km in the reserve that differed in area, flow\nregimes, Gracilaria cover, grain size, and proximity to the Spartina salt\nmarsh. The three flats represented the continuum of estuarine habitats where\nGracilaria naturally occurs in this area. We established the 48 plots along\nthe mean low water line at 5-m intervals by adding 3-m steel rebar 1.2 m into\nthe substrate at each plot-corner. Treatments were randomly assigned to the\nplots to avoid potentially confounding small-scale effects of site (and all\nplots had only few Diopatra tubes). Gracilaria was fixed in a plot with metal\n'u-pegs'\\u00a0(constructed from clothes hangers) by physically staking\nhandful-sized 'clumps'\\u00a0of loose thalli to the sediment surface. Pegs were\nflushed with the sediment surface to avoid above-surface experimental\nartifacts. Our six treatments were based on the total number of pegs per 25\nsquare meters\\u00a0(arranged in squared grids) as follows: 0 (0\\u00d70), 9\n(3\\u00d73), 36 (6\\u00d76), 100 (10\\u00d710), 225 (15\\u00d715), and 400\n(20\\u00d720). Gracilaria was collected from nearby locations and added to\nplots in the u-peg grids in August 2013. Treatments were maintained and\nresponse variables quantified approximately monthly from September 2013 to\nJune 2014 (treatments were maintained and measured at total of 10 times). For\neach plot visit we quantified the cover of Gracilaria (in 10 randomly placed\n0.25 square meter\\u00a0quadrats per plot) and seven ecosystem functions (see\nnext section for detail) before maintaining Gracilaria densities (by\nreplenishing u-pegs devoid of Gracilaria and manually removing Gracilaria from\ncontrol plots).\n \nTo examine the effect of Gracilaria on epifauna, we positioned a 0.25 square\nmeter\\u00a0quadrat in the center of each plot and collected all Gracilaria and\nits associated epifauna into a ziptop bag. In the laboratory, Gracilaria was\nrinsed in freshwater and shaken for about 1 min to remove epifauna, which were\ncaptured on a 500 micron sieve. Epifauna were identified and enumerated to\nbroad taxonomic groupings (typically family level) under a stereomicroscope\n(~18x, Nikon SMZ800). For simplicity, all faunal data were standardized to\nunit area. Taxonomic richness was rescaled to unit area using the species-area\nrelationship\\u00a0and assuming a conservative value of 0.15 for z.\n \nTo quantify whether Gracilaria attenuates hydrodynamic forces, we used gypsum\ndissolution blocks that dissolve at a rate proportional to water velocity and\nthus represent an integrated proxy for tidal currents and wave exposure. We\ncreated gypsum blocks as hemispheres (\\u2300 = 6.5 cm) from dental plaster\n(Die Keen, Heraeus Kalzer), covered on the bottom with two layers of\npolyurethane to ensure that an equal surface area would be subject to\ndissolution. Gypsum blocks were dried at 60 degrees C for a minimum of 24 h\nbefore recording the initial mass and deploying one block flush with the\nsubstrate surface in the center of each plot for 4 d. Following retrieval,\ngypsum blocks were dried and reweighed, and the dissolution rate calculated as\ngrams of gypsum dissolved per day. Because lower dissolution rates indicate\ngreater flow reduction, dissolution rates were reflected using the equation\n\\u2013fi+max(fi), so that greater flow reduction corresponds with a positive\ncontribution to ecosystem functioning.\n \nTo examine the effect of Gracilaria on sediment stabilization, we marked all\ncorner poles at 20 cm above the substrate surface in August 2013. The distance\nbetween the marking and substrate surface was measured with a ruler to the\nnearest 0.5 cm at the end of each month. We calculated the monthly (30 d)\nchange in height in cm by subtracting the final from initial distance to the\nsubstrate (using the average of the 4 corners per plot) and correcting for the\ntime interval between measurements. Accretion and erosion are represented as\npositive and negative values, respectively.\n \nTo assess the effectiveness of Gracilaria as a nursery habitat for\ncommercially and recreationally important species, we sampled the entire plot\nusing a 1.2-m high \\u00d7 6.7-m wide nylon seine net (The Fish Net Company,\nJonesville, LA; mesh size = 3.175 mm) during a falling tide. Upon completion\nof a pass, we swiftly pulled the net taught, tilted it into a horizontal\nposition, and lifted it from the water into an adjacent boat (R/V Adelaide) in\na single motion. Organisms (greater than 1 cm) retained on the boat were\nidentified to the family-level and enumerated before being returned to the\nwater. Abundances were reported per unit area (dividing by 25 square meters)\nand richness data were rescaled to unit area using the species\\u2013area\nrelationship\\u00a0and assuming a conservative value of 0.15 for z.\n \nTo quantify the effect of Gracilaria on decomposition processes, standing dead\nSpartina stems were collected from adjacent salt marshes, washed, and dried at\n60 degrees C for a minimum of 72 h (until no further weight loss). We pooled\nmultiple stems to achieve an initial mass of 7.0 +/-\\u00a00.5 g and placed\nthem inside a mesh litter bag, which was closed and deployed on the sediment\nsurface in the center of each plot. Bags were retrieved just prior to the next\ntreatment maintenance. Remaining stem material was washed, dried, and weighed\nand decomposition rate was reported as the mass lost in grams per month.\n \nTo simplify our analyses and remove temporal autocorrelation, we calculated\nthe average response of each function in each plot using the full 10 month\ndata set (48 plots sampled each month). At the end of the experiment we\nmeasured four additional functions (months 8 through 10). Because we did not\nhave seasonal data for these responses they were excluded from the main\nanalysis of multifunction effects.\n \nTo sample benthic infauna, triplicate core samples (5-cm diameter, 15-cm\ndepth, volume = 294.5 cubic cm) were taken equidistant along a diagonal\ntransect of each plot on June 25, 2014. The three sediment core samples from\neach plot were pooled into a ziptop bag. Upon return to the laboratory, the\ncontent of each bag were drained and rinsed over a 1-mm mesh sieve to remove\nfine sediments. Infauna retained on the sieve were preserved in 75% ethanol.\nThe 1-mm mesh-size was chosen to concentrate sampling efforts on juvenile and\nearly life stages of crustaceans, molluscs, and larger polychaete taxa.\nInfauna were identified and enumerated under a stereomicroscope (~18x, Nikon\nSMZ800) to families, and, in some cases, phyla. Infaunal data were\nstandardized and rescaled to unit volume (using the reciprocal of 0.8836 L and\na conservative z of 0.15) following the same methods described previously for\nepifauna and nursery functions.\n \nTo evaluate the effect of Gracilaria on ray foraging activity, we counted the\nnumber of ray holes in each plot on 3 to 4 different days in a given month. We\nhere report the average number of ray holes standardized to unit area (by\ndividing by 25 square meters) during a given low tide on a single day.\n \nTo investigate the association of waterfowl with Gracilaria, we delimited the\n48 plots into four sites based on spatial proximity (plots 1-12, 13-24, 25-36,\nand 37-48) and surveyed all waterfowl activity occurring within a site\n(containing 12 plots) for a 15-min period during low tide. Bird counts were\nmade through binoculars from our research vessel from a distance of about 100\nm to avoid disturbances arising from our presence. We tallied the number of\nbirds initially present, and that became present, within the boundaries of\neach plot during the observation period. After completing the 15-min\nobservation of a site, we moved to a new vantage point for observing the next\n12 plots. Hence, by repeating this procedure at all sites, all 48 plots were\nsampled with equivalent effort in a ~1 h period. Because measurements were\nmade on 1 to 3 different days in a given month, we present the average number\nof birds tallied per unit area (by dividing by 25 square meters) per unit time\n(by multiplying by 4; 15 min x 4 = 60 min = 1 h) of low tide.

attribute NC_GLOBAL project String small grazers facilitating fungal disease
attribute NC_GLOBAL projects_0_acronym String small grazers facilitating fungal disease
attribute NC_GLOBAL projects_0_description String In terrestrial communities, grazer-facilitation of fungal disease in plants has been studied for over a century. Despite the prevalence of this interaction in terrestrial systems, it was not considered relevant to the structure of marine plant communities until the investigator's recent work in salt marshes. By manipulating both grazer and fungal presence, he demonstrated that snail grazing and subsequent fungal infection in live grass led to drastic reductions in plant growth and, at high grazer densities, destruction of canopy. If grazer promotion of fungal disease in marine plants is not limited to marshes (as suggested by preliminary data from a world-wide survey of 4 marine plant ecosystems) then small grazers that take small bites out of plants could be exerting similarly strong, but undetected control over marine plants globally. In addition, since physical stress commonly reduces plant immune responses, intensifying multiple stressors associated with marine global change could intensify and destabilize these unstudied grazer-disease-plant interactions. To test the global generality of this potentially keystone ecological interaction, this project will answer the following questions with a combination of multi-site surveys and manipulations across 4 ecosystems spanning 2 continents: 1) Is grazer facilitation of fungal disease in marine plants a common but overlooked interaction? 2) What is the resultant impact of grazer-facilitated fungal infection on marine plant growth? 3) How do multiple stressors impact the strength of grazer facilitation of fungal disease in marine plants? The work represents a transformative step forward in our understanding of plant-grazer interactions in marine ecosystems as it fills a > 100-year intellectual gap in our understanding of top-down control in marine plant ecosystems: Do small grazers commonly facilitate fungal disease in marine plants and does this interaction suppress plant growth?\nEvidence for this cryptic, yet powerful mechanism of grazer regulation of marine plants will compel marine ecologists to reevaluate our understanding of top-down control and lead to widespread integration of disease dynamics in marine food web ecology.\nThe consequences of marine plant ecosystem health are far-reaching for humans, since these communities provide many essential services. Results from this study will allow managers to better predict effects of disease and global change on marine plant systems and formulate effective strategies for conservation. To help integrate plant disease dynamics into marine ecology and conservation, the investigator will: (1) produce an edited volume on Food Webs and Disease in Marine Ecosystems and (2) work closely with The Nature Conservancy to incorporate findings into their global marine learning exchanges. In addition, an integrated educational plan will increase student: (1) understanding of disease and food web dynamics in marine ecosystems and (2) consideration of marine science careers.
