DISSERTATION RESEARCH: Causes and consequences of cyanobacteria dominance and toxin production: Interactions among nutrient supply, nutrient ratios and light intensity

这一博士论文改进项目将研究导致湖泊和水库藻类水华的因素。一种实验方法，其中磷的绝对浓度，磷与氮的相对数量，以及光量将被用来评估这些因素如何影响藻类物种的发生和丰度。这项研究还将评估哪些因素的组合导致蓝藻产生毒素。许多内陆水域受到过量营养输入的影响，这可能导致藻类表面浮渣。这种文化富营养化可能导致财产价值和娱乐机会的下降，在某些情况下可能会导致饮用水供应中断。了解导致藻类大量繁殖的因素对于制定减轻地表水营养盐污染影响的战略非常重要。

This doctoral dissertation improvement project will study factors causing algal blooms in lakes and reservoirs. An experimental approach in which the absolute concentration of phosphorus, the amount of phosphorus relative to nitrogen, and the amount of light are manipulated will be used to assess how these factors affect the occurrence and abundance of algal species. The study will also assess what combination of factors lead to toxin production by blue-green algae.Many inland waters are impacted by excessive nutrient input, which can lead to surface scums of algae. This cultural eutrophication can lead to decreases in property values and recreational opportunities, and in some cases can result in disruptions of drinking water supplies. Understanding the factors leading to algal blooms is important in developing strategies to mitigate the effects of nutrient pollution in surface waters.
