The phenotypes were Small (mean size \\u00b1 SE; 18.88 \\u00b1 0.17 mm shell length), Medium (32.23 \\u00b10.21 mm shell length) and Large (39.04 \\u00b1 0.32 mm shell length), with each phenotype receiving at least 100 oysters from each of the same 16 family lines to produce treatments of comparable genetic diversity.\\u00a0 Oysters were manipulated on concrete tiles that were deployed at a mid- intertidal elevation along the eastern shoreline of Chowder Bay, Sydney Harbour, Australia (33\\u00b050\\u201919.80\\u201dS, 151\\u00b015\\u201916.50\\u201dE). Oyster phenotypic diversity (3 levels; 1, 2 or 3 size classes/tile) and predator access (2 levels: small mesh cages and large mesh cages) were manipulated in a fully orthogonal experiment on concrete tiles, measuring 30cm (length) x 30cm (width) x 4cm (height). The large mesh was 2.5 cm in diameter. The small mesh was 1.5 cm in diameter. In total we had 14 treatments: small and large mesh cages containing small, medium and large oysters on their own, all pairwise combinations, and all three phenotypes together. There were five replicates per treatment, giving a total of 70 tiles. Oysters were glued to concrete tiles using a 2-part epoxy adhesive (Megapoxy HT, Permatech), with the various body sizes haphazardly interspersed on tiles assigned to receive multiple phenotypes.\\u00a0 There was a 3 cm margin with no oysters around each plate. No oysters died from this process. Prior to caging of tiles, each was photographed (with a scale bar included) to determine the initial size of all oysters and the position on each tile of the various size classes.\\u00a0 We used maximum shell length along the anterior\\u2013posterior axis as our measure of body size Tiles were then enclosed within a box cage consisting of stainless steel mesh of the assigned size. The tiles were not affixed to the mesh cage but sat on the bottom of it. The mesh extended 10 cm above the surface of the tile. Mesh was secured on the underside of the tile with cable ties. Tiles were placed in Chowder Bay at the mid intertidal elevation at which oysters naturally occur on 17th November 2015. Tiles were interspersed with respect to treatment, separated by at least 0.5 m and wedged between boulders to minimise flipping by waves. The tiles were sampled at 1 week and after 8 weeks (15 Jan 2016). At 1 week, three tiles were flipped by wave action but no damage to oysters or cages were observed, so these were righted and secured in new positions between boulders. No other flipping or damage to tiles was recorded at the end of the experiment."; String awards_0_award_nid "709941"; String awards_0_award_number "OCE-1652320"; String awards_0_data_url "http://www.nsf.gov/awardsearch/showAward.do?AwardNumber=1652320"; String awards_0_funder_name "NSF Division of Ocean Sciences"; String awards_0_funding_acronym "NSF OCE"; String awards_0_funding_source_nid "355"; String awards_0_program_manager "Michael E.

This 5-year CAREER project will study disease prevalence and intensity in two marine foundation species - the seagrass Zostera marina and the Eastern oyster Crassostrea virginica. More specifically, host-disease relationships will be explored to understand how genetic diversity and population density of the host species impacts disease transmission and risk. This work will pair large-scale experimental restorations and smaller-scale field experiments to examine disease-host relationships across multiple spatial scales. Comparisons of patterns and mechanisms across the two coastal systems will provide an important first step towards identifying generalities in the diversity-density-disease relationship. To enhance the broader impacts and utility of this work, the experiments will be conducted in collaboration with restoration practitioners and guided by knowledge ascertained from key stakeholder groups. The project will support the development of an early career female researcher and multiple graduate and undergraduate students. Students will be trained in state-of-the-art molecular techniques to quantify oyster and seagrass parasites. Key findings from the surveys and experimental work will be incorporated into undergraduate courses focused on Conservation Biology, Marine Biology, and Disease Ecology. Finally, students in these courses will help develop social-ecological surveys and mutual learning games to stimulate knowledge transfer with stakeholders through a series of workshops. The relationship between host genetic diversity and disease dynamics is complex. In some cases, known as a dilution effect, diversity reduces disease transmission and risk. However, the opposite relationship, known as the amplification effect, can also occur when diversity increases the risk of infection. Even if diversity directly reduces disease risk, simultaneous positive effects of diversity on host density could lead to amplification by increasing disease transmission between infected and uninfected individuals. Large-scale field restorations of seagrasses (Zostera marina) and oysters (Crassostrea virginica) will be utilized to test the effects of host genetic diversity on host population density and disease prevalence/intensity. Additional field experiments independently manipulating host genetic diversity and density will examine the mechanisms leading to dilution or amplification. Conducting similar manipulations in two marine foundation species - one a clonal plant and the other a non-clonal animal - will help identify commonalities in the diversity-density-disease relationship. Further, collaborations among project scientists, students, and stakeholders will enhance interdisciplinary training and help facilitate the exchange of information to improve management and restoration efforts. As part of these efforts, targeted surveys will be used to document the perceptions and attitudes of managers and restoration practitioners regarding genetic diversity and its role in ecological resilience and restoration."; String projects_0_end_date "2022-01"; String projects_0_geolocation "Coastal New England"; String projects_0_name "CAREER: Linking genetic diversity, population density, and disease prevalence in seagrass and oyster ecosystems"; String projects_0_project_nid "709942"; String projects_0_start_date "2017-02"; String publisher_name "Biological and Chemical Oceanographic Data Management Office (BCO-DMO)"; String publisher_type "institution"; String sourceUrl "(local files)"; String standard_name_vocabulary "CF Standard Name Table v55"; String summary "Database of oyster mortality based on body size treatment"; String title "[Oyster mortality] - Database of oyster mortality based on body size treatment (CAREER: Linking genetic diversity, population density, and disease prevalence in seagrass and oyster ecosystems)"; String version "1"; String xml_source "osprey2erddap.update_xml() v1.3"; } }

Tabledap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/pmelTaoDySst.htmlTable?longitude,latitude,time,station,wmo_platform_code,T_25&time>=2015-05-23T12:00:00Z&time<=2015-05-31T12:00:00Z
Thus, the query is often a comma-separated list of desired variable names,
followed by a collection of
constraints (e.g., variable<value),
each preceded by '&' (which is interpreted as "AND").
