attribute NC_GLOBAL acquisition_description String Culture pots were placed in large thermally insulated coolers in a\ntemperature-controlled water bath at 15\\u00b0 C under saturating illumination\nof ~550 \\u00b5moles photons/m^2/s on a 12:12 L:D cycle. pCO2 treatments were\nsupplied to closed culture pots by use of a gas mixing system combining\nnitrogen, oxygen and carbon dioxide to specific CO2 partial pressures, 20.9%\noxygen and the balance being nitrogen.\n \nChlorophyll a was extracted from Ulva tissue following the procedure described\nin Duncan and Harrison (1982). Chlorophyll a concentrations were measured\nusing a Shimadzu UV-2450 UV-visible spectrophotometer.

attribute NC_GLOBAL projects_0_description String Benthic macroalgae contribute to intensely productive near shore  ecosystems and little is known about the potential effects of ocean  acidification on non-calcifying macroalgae. Kübler and Dudgeon will test  hypotheses about two macroalgae, Ulva spp. and Plocamium cartilagineum,  which, for different reasons, are hypothesized to be more productive  and undergo ecological expansions under predicted changes in ocean  chemistry. They have designed laboratory culture-based experiments to  quantify the scope for response to ocean acidification in Plocamium,  which relies solely on diffusive uptake of CO2, and populations of Ulva  spp., which have an inducible concentrating mechanism (CCM). The  investigators will culture these algae in media equilibrated at 8  different pCO2 levels ranging from 380 to 940 ppm to address three key  hypotheses. The first is that macroalgae (such as Plocamium  cartilagineum) that are not able to acquire inorganic carbon in changed  form will benefit, in terms of photosynthetic and growth rates, from  ocean acidification. There is little existing data to support this  common assumption. The second hypothesis is that enhanced growth of Ulva  sp. under OA will result from the energetic savings from down  regulating the CCM, rather than from enhanced photosynthesis per se.  Their approach will detect existing genetic variation for adaptive  plasticity. The third key hypothesis to be addressed in short-term  culture experiments is that there will be a significant interaction  between ocean acidification and nitrogen limited growth of Ulva spp.,  which are indicator species of eutrophication. Kübler and Dudgeon will  be able to quantify the individual effects of ocean acidification and  nitrogenous nutrient addition on Ulva spp. and also, the synergistic  effects, which will inevitably apply in many highly productive, shallow  coastal areas. The three hypotheses being addressed have been broadly  identified as urgent needs in our growing understanding of the impacts  of ocean acidification.
