The relationship between the ciguatoxin-producer benthic dinoflagellate Gambierdiscus and other epibenthic dinoflagellates in the Canary Islands was examined in macrophyte samples obtained from two locations of Fuerteventura Island in September 2016. The genera examined included Coolia, Gambierdiscus, Ostreopsis, Prorocentrum, Scrippsiella, Sinophysis, and Vulcanodinium. Distinct assemblages among these benthic dinoflagellates...

Summary Here it is reported the first detection of DV ‐chl a together with the usual chl a in the marine dinoflagellate A lexandrium ostenfeldii from the B altic S ea. Growth response and photosynthetic parameters were examined at two irradiances (80 and 240 μmol photons m −2 s −1 ) and temperatures (15°C and 19°C) in a divinylic strain ( AOTV ‐OS20) versus a monovinylic one ( AOTV ‐OS16), using in vivo chl a fluorescence kine...
