Uncovering a “sleeping giant” Arctic cyst bed
Don Anderson gave a virtual presentation at the University of Alaska Fairbanks on 10/13/21 focusing on the potential for a significant increase in Alexandrium catenella harmful algal blooms due to warming Arctic waters. During annual blooms, the cells produce saxitoxins, potent neurotoxins, which accumulate in the food web and can lead to paralytic shellfish poisoning…

Harmful Algal Bloom Dynamics in the Gulf of Maine Coastal waters of New England are subject to annually recurring outbreaks of paralytic shellfish poisoning (PSP) caused by the dinoflagellate Alexandrium catenella. Another emerging threat in this region is amnesic shellfish poisoning (ASP) caused by toxic diatoms in the genus Pseudo-nitzschia. These blooms come with significant economic and social impacts,…
