054664ValielaThis dissertation enhancement proposal supports the research of Ms. Mirta Teichberg, under the supervision of Dr. Ivan Valiela, Boston University, to work with Dr. Thais N. Corbisier at the University of Sao Paulo in Brazil, and with Dr. Oscar O. Iribarne at the National University of Mar del Plata in Argentina. This research will look at how changes in nutrient supply or grazing pressure set the stage for blooms of green, red, or brown macroalgae in a variety of temperate and tropical coastal environments that capture the range of bloom phenomena in shallow coastal waters of the world. This support will allow Ms. Teichberg to carry out research on macroalgae in the south coast of Brazil and the South Atlantic Coast of Argentina. The planned experiments will lead to knowledge about the potential for macroalgal blooms in a highly diverse, high-rainfall, tropical, and a biotically limited desert-like temperate environment. The PI has studied the algal bloom problem in the U.S., and this project will now add South America's wet-warm and dry-temperate sites for comparison. Algal blooms are harmful because they cause anoxic conditions and the loss of commercial species, such as shellfish. The results of the study will help inform management practices to prevent large macroalgal blooms from occurring in these regions.

054664ValielaThis论文增强提案支持Mirta Teichberg女士的研究，在波士顿大学博士Ivan Valiela的监督下，与Thais N.巴西圣保罗大学的Corbisier和Oscar O.阿根廷马德普拉塔国立大学的Iribarne说。 这项研究将着眼于如何在营养供应或放牧压力的变化设置阶段的水华的绿色，红色，或棕色的大型海藻在各种温带和热带沿海环境，捕获的范围内的水华现象在世界的浅沿海沃茨。 这一支持将使Teichberg女士能够在巴西南部海岸和阿根廷南大西洋海岸开展大型藻类研究。 计划中的实验将有助于了解在高度多样化、高降雨量、热带和生物有限的沙漠般的温带环境中大型藻类大量繁殖的潜力。 PI研究了美国的藻类水华问题，这个项目现在将增加南美洲的湿暖和干温带地区进行比较。 藻类大量繁殖是有害的，因为它们造成缺氧条件和贝类等商业物种的损失。 研究结果将有助于为管理实践提供信息，以防止这些地区发生大型藻类水华。
