Vulcanodinium rugosum, a recently described dinoflagellate species producing a potent neurotoxin (pinnatoxin G), has been identified in French Mediterranean lagoons and was responsible for recurrent episodes of shellfish toxicity detected by mouse bioassay. Until now, the biology and physiology of V. rugosum have not been fully investigated. We studied the growth characteristics and toxicity of...

This quantitative dinoflagellate cyst study reveals an enormous difference in survival rates oxygenated versus anoxic sediments. Replicate samples of concentrated natural cysts with the same initial species composition (1.4 × 104 resting cysts·cm−3 sediment, 61% filled live-appearing contents) were placed bags 20 µm plankton screen. containing 10.0 cm−3 on seafloor different environments Long I...
