U.S.-Argentina: Bottom-up and Top-down Controls of Macroalgal Blooms: A Global Comparison of Macroalgal Response

054664Valiela本学位论文增强建议支持Mirta Teichberg女士在波士顿大学Ivan Valiela博士的指导下与巴西圣保罗大学的Thais N.Corbisier博士和阿根廷马德普拉塔国立大学的Oscar O.Iribarne博士合作的研究。这项研究将着眼于营养供应或放牧压力的变化如何在各种温带和热带沿海环境中为绿色、红色或棕色大型藻类的水华奠定基础，这些环境捕捉到了世界浅海水域的各种水华现象。这项支持将使Teichberg女士能够在巴西南海岸和阿根廷南大西洋海岸开展大型藻类研究。计划中的实验将带来关于在高度多样化、高降雨量、热带和生物有限的沙漠般的温带环境中发生大型藻类水华的可能性的知识。国际和平研究所已经研究了美国的藻类水华问题，该项目现在将增加南美洲的湿温暖和干燥温带地点进行比较。藻类水华是有害的，因为它们导致缺氧条件和商业物种的损失，如贝类。这项研究的结果将有助于为防止大型大型藻类水华在这些地区发生的管理实践提供参考。

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.
