attribute NC_GLOBAL acquisition_description String We utilised 10-month old oysters, spawned under the breeding program at the\nPort Stephens Fisheries Institute (PSFI) in January 2015 and subsequently\ngrown out on nearby oyster leases, to establish three phenotypic treatments\nwith respect to size. The phenotypes were Small (mean size \\u00b1 SE; 18.88\n\\u00b1 0.17 mm shell length), Medium (32.23 \\u00b10.21 mm shell length) and\nLarge (39.04 \\u00b1 0.32 mm shell length), with each phenotype receiving at\nleast 100 oysters from each of the same 16 family lines to produce treatments\nof comparable genetic diversity.\\u00a0\n \nOysters were manipulated on concrete tiles that were deployed at a mid-\nintertidal elevation along the eastern shoreline of Chowder Bay, Sydney\nHarbour, Australia (33\\u00b050\\u201919.80\\u201dS,\n151\\u00b015\\u201916.50\\u201dE).\n \nOyster phenotypic diversity (3 levels; 1, 2 or 3 size classes/tile) and\npredator access (2 levels: small mesh cages and large mesh cages) were\nmanipulated in a fully orthogonal experiment on concrete tiles, measuring 30cm\n(length) x 30cm (width) x 4cm (height). The large mesh was 2.5 cm in diameter.\nThe small mesh was 1.5 cm in diameter. In total we had 14 treatments: small\nand large mesh cages containing small, medium and large oysters on their own,\nall pairwise combinations, and all three phenotypes together. There were five\nreplicates per treatment, giving a total of 70 tiles.\n \nOysters were glued to concrete tiles using a 2-part epoxy adhesive (Megapoxy\nHT, Permatech), with the various body sizes haphazardly interspersed on tiles\nassigned to receive multiple phenotypes.\\u00a0 There was a 3 cm margin with no\noysters around each plate. No oysters died from this process.\n \nPrior to caging of tiles, each was photographed (with a scale bar included) to\ndetermine the initial size of all oysters and the position on each tile of the\nvarious size classes.\\u00a0 We used maximum shell length along the\nanterior\\u2013posterior axis as our measure of body size\n \nTiles were then enclosed within a box cage consisting of stainless steel mesh\nof the assigned size. The tiles were not affixed to the mesh cage but sat on\nthe bottom of it. The mesh extended 10 cm above the surface of the tile. Mesh\nwas secured on the underside of the tile with cable ties.\n \nTiles were placed in Chowder Bay at the mid intertidal elevation at which\noysters naturally occur on 17th November 2015. Tiles were interspersed with\nrespect to treatment, separated by at least 0.5 m and wedged between boulders\nto minimise flipping by waves. The tiles were sampled at 1 week and after 8\nweeks (15 Jan 2016). At 1 week, three tiles were flipped by wave action but no\ndamage to oysters or cages were observed, so these were righted and secured in\nnew positions between boulders. No other flipping or damage to tiles was\nrecorded at the end of the experiment.

attribute NC_GLOBAL projects_0_description String NSF Award Abstract:\nDisease outbreaks in the ocean are increasing, causing losses of ecologically important marine species, but the factors contributing to these outbreaks are not well understood. 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.\nThe 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.
