attribute NC_GLOBAL acquisition_description String Sporophytic specimens of Pterosiphonia bipinnata and Corallina vancouveriensis\nwere collected from the mid to low intertidal zone on San Juan Island,\nWashington (Deadman Bay: 48 30' 48.93\\\"N, 123 8'56.14\\\"W), immediately\ntransported to Friday Harbor Laboratories (FHL), and maintained in an outdoor\nseawater table for up to one week before testing. Reproductive parent fronds\nwere held at ambient levels of seawater pH/pCO2 and were only exposed to\nexperimental conditions while releasing spores. Spore release and settlement\nwas performed in the Ocean Acidification Environmental Laboratory (OAEL) at\nFHL, allowing precise control of pH and temperature in a flow-through system.\nTwo pH treatments were established by bubbling CO2 (7.75, 7.30 total scale) at\n11C and confirmed with carbonate water chemistry analyses. Specifically,\nspectrophotometric pH was determined as per SOP6 and total alkalinity was\nmeasured using an open cell titrator as outlined in SOP3b (Dickson et al.\n2007). Ambient pH values for the Salish Sea are approximately 7.8, and pH as\nlow as 7.3 has been documented in nearshore environments in Washington.\\u00a0\n \n\\u00a0The spore settlement apparatus consisted of a carriage system that\nslowly (1-2.5 cm/hr.) drove reproductive algal thalli across a glass\nsettlement plate (0.6 x 7.6 x 60 cm), while releasing spores. The working\nsection (14 x 1.5 cm) was defined at one end of the plate. Spores landing in\nthe working section had a decreasing gradient of attachment time, determined\nby the rate parent thalli were driven across the plate and the time the plate\nwas allowed to set. Error in attachment time was estimated to be 6-12 minutes\ngiven sinking rates of spores of comparable spore size (50-100 um) and release\nheight (5-10 cm).\n \nThe shear flume was designed to release a tall column of water that flushes\nquickly across the working section of the spore settlement plate. Water column\nheight was varied to create a range of shear stresses. \\u00a0Shear stresses\ngenerated by each water column height were calculated according to Schultz et\nal. 2000, using the height of the channel (4.3 mm), the pressure gradient\nacross the working section (measured with a manometer), and the length of the\nworking section. \\u00a0Most spores were removed in the first 10 seconds of\ncontinuous exposure to shear and longer exposure times result in little\nadditional detachment, so trials were limited to 15 seconds.\\u00a0\n \nPrior to each test, the shear flume was fitted on the settlement plate with\nclamps and the released spores were photographed using a microscope\n(Steindorff SXC, New York Microscopes) connected to a camera (Nikon Coolpix\nS3300), using the lines drawn in the working section for reference. For the\nattachment time assay, a low shear stress (1 Pa) was applied and the remaining\nspores were photographed and counted.\\u00a0\n \nFor the attachment strength assay, spores were allowed to set in stationary\nwater for 35-48 hours in P. bipinnata and for 5-10 hours in C.\nvancouveriensis, since maximum attachment of each species was found in these\ntime frames using the logistic regression analyses of attachment time. For P.\nbipinnata, replication was achieved by repeating the experiment in time since\none frond moved across the entire settlement plate in each run. Due to\nlimitations with C. vancouveriensis spore release, several fronds were used to\nprovide sufficient spores for this assay. In this case, each frond that\nreleased spores was considered a replicate, and this was repeated across\nseveral days. All spore releases were natural, as attempts to artificially\ninduce spore release (osmotic, temperature, or light) were unsuccessful.\\u00a0\n \nAttached spores were exposed to increasing shear stresses (1, 4, 7, 17 and 20\nPa). Shear stresses in the flume represented boundary layer velocities of 0.2\n\\u2013 4 ms-1, similar to intertidal field conditions. At each position and at\neach shear stress applied, spores were counted through photo-analysis in\nImageJ (version 1.48; U.S. National Institutes of Health, Bethesda, MD). With\neach successive application of shear stress, we expected an increasing\npercentage of spores to detach from the settlement plate, up to a maximum\nvalue assuming some spores would be stronger than our assay. The effect of\nshear stress on spore detachment in each species was tested using an\nexponential rise-to-maximum non-linear regression (SigmaPlot 11.0, R2 = 0.84 -\n0.99), which provided estimates of two parameters: the maximum percentage of\nspores detached and the initial dependence of detachment on shear stress. The\nfirst derivatives of fitted, non-linear regressions were plotted to estimate\nfrequency distributions of spore attachment strength.

attribute NC_GLOBAL projects_0_acronym String OA - Ecomaterials Perspective
attribute NC_GLOBAL projects_0_description String Effects of Ocean Acidification on Coastal Organisms: An Ecomaterials Perspective\nThis award will support researchers based at the University of Washington's Friday Harbor Laboratories. The overall focus of the project is to determine how ocean acidification affects the integrity of biomaterials and how these effects in turn alter interactions among members of marine communities. The research plan emphasizes an ecomaterial approach; a team of biomaterials and ecomechanics experts will apply their unique perspective to detail how different combinations of environmental conditions affect the structural integrity and ecological performance of organisms. The study targets a diversity of ecologically important taxa, including bivalves, snails, crustaceans, and seaweeds, thereby providing insight into the range of possible biological responses to future changes in climate conditions. The proposal will enhance our understanding of the ecological consequences of climate change, a significant societal problem.\nEach of the study systems has broader impacts in fields beyond ecomechanics. Engineers are particularly interested in biomaterials and in each system there are materials with commercial potential. The project will integrate research and education by supporting doctoral student dissertation research, providing undergraduate research opportunities via three training programs at FHL, and summer internships for talented high school students, recruited from the FHL Science Outreach Program. The participation of underrepresented groups will be broadened by actively recruiting URM and female students. Results will be disseminated in a variety of forums, including peer-reviewed scientific publications, undergraduate and graduate course material, service learning activities in K-8 classrooms, demonstrations at FHL's annual Open House, and columns for a popular science magazine.
