What is the Best Frame of Reference for Evaluating the Biological Consequences of Ocean Acidification?Tuesday, June 19th, 2012
Stumpp, M., Wren, J., Melzner, F., Thorndyke, M.C. and Dupont, S.T. 2011a. CO2 induced seawater acidification impacts sea urchin larval development I: Elevated metabolic rates decrease scope for growth and induce developmental delay. Comparative Biochemistry and Physiology, Part A 160: 331-340.
Stumpp et al. (2011a) evaluated the impacts of elevated seawater pCO2 (1264 ppm vs. 375 ppm) on the early development of, and the larval metabolic and feeding rates of, a model marine organism: Strongylocentrotus purpuratus, commonly known as the purple sea urchin. This was done via a protocol where growth and development were assessed daily, for a period of three weeks, in terms of total body length, body rod length, postoral rod length and posterolateral rod length, as well as mortality and feeding and metabolic rates. So what did their research show? (more…)
