Influence of Environmental Variables on Growth of Toxigenic Golden Alga (Prymnesium parvum): A Laboratory Test of Field-Generated Hypotheses


July 2015 - December 2017


While new information has recently become available regarding the association of environmental variables with the highly toxic golden alga, this information is based mostly on descriptive observations in the field. The purpose of this study is conduct definitive tests of field-generated hypotheses under the controlled environment of a laboratory. Knowledge obtained may be useful curb the further spread and mitigate the toxic effects of golden alga on aquatic natural resources.
