Amphidomataceae (Dinophyceae) in the western Greenland area, including description of Azadinium perforatum sp. nov.
Azaspiracids (AZA) are lipophilic marine biotoxins associated with shellfish poisoning which are produced by some species of Amphidomataceae. Diversity and global biogeography of this family are still poorly known. In summer 2017 plankton samples were collected from the central Labrador Sea and west...
