Harmful algal blooms and eutrophication: Nutrient sources, composition, and consequences
Although algal blooms, including those considered toxic or harmful, can be natural phenomena, the nature of the global problem of harmful algal blooms (HABs) has expanded both in extent and itsExpand

Mixotrophy, a major mode of nutrition for harmful algal species in eutrophic waters
Historically most harmful algal species (HAS) have been thought to be strictly phototrophic. Mixotrophy, the use of phototrophy and heterotrophy in combination, has been emphasized as operativeExpand

Effect of irradiances up to 2000 μE m−2 s−1 on marine Synechococcus WH7803—I. Growth, pigmentation, and cell composition
Abstract We grew Synechococcus WH7803 at rates exceeding 1.4 d −1 at irradiances from 200 to 2000 μE m −2 s −1 under continuous light in nutrient replete media with no evidence of photoinhibition.Expand
