Evolutionary lineages and character state evolution of the benthic thecated dinoflagellate, gambierdiscus (dinophyceae)

The genera of Gambierdiscus, Ostreopsis and Coolia are benthic marine dinoflagellates that are known to produce biotoxins that cause illness in human after consumption of the contaminated seafood. These benthic marine dinoflagellates are commonly found in the warm tropical and subtropical waters. Th...
