Genetic information on the key taxa is sorely lacking. For example, the gene sequence for dinoflagellate luciferase is known from only one species. More studies using relevant levels of stimuli are needed. For example, flow studies with copepods can identify the fluid parameters stimulating their light emission. The complete transduction and signaling pathway has yet to be described in a single luminescent species.
Intensive investigations require that organisms be established in laboratory cultures.
This is generally possible for the dinoflagellates, but needs to be done for copepods. Detailed knowledge of the life cycles of key taxa are required. Taxonomic enumeration of plankton samples will quantify the fraction of autotrophic and heterotrophic dinoflagellates for varied environmental conditions and may help reveal clues as to environmental and biological conditions regulating the composition of dinoflagellate assemblages.
