attribute NC_GLOBAL acquisition_description String Growth rate was measured in batch culture by pooling all plant thalli and\nsumming them to attain the datum for the culture pot. Hence, the culture pot\nis the unit of replication. Growth rate was measured by recording the fresh\nweight of living material approximately every 6 days. Plant tissue was lightly\nstacked and gently pressed between layers of Kimwipes. This method reduced\nhandling time and removed superficial water prior to weighing. The stack was\nthen weighed together to attain the fresh weight for the pot. Relative growth\nrate was then calculated following L\\u00fcning (1990):\\u00a0 RGR(% . day-1 =\n(100*Ln(W2/W1))/(t2-t1), where W1, W2, t1, t2 correspond to fresh weights at\ntimes 1 (t1) and 2 (t2), respectively. The weekly relative growth rates track\nthe dynamics of growth and its variation during the experiment. In addition to\ngrowth rates estimated approximately weekly, estimates of overall net and\nabsolute growth rates integrated across the 3-week experiment were also made\nusing the initial and final starting masses. The difference between the\noverall net and absolute growth rate estimates is that the latter estimate\nincludes small tissue fragments derived from whole thalli that occasionally\nappeared at the end of a weekly growth interval, but were thought to not be\nhealthy viable fragments that would generate new growth in the subsequent\ninterval so were discarded at the beginning of the next growth interval.\n \nNote: Trial 1 was a pilot test of culture system and methodological procedures\nso was not used for data collection

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.
