The marine algal biotoxin, domoic acid (DA), is produced by certain members of the diatom genus Pseudo-nitzschia. This neurotoxin has been responsible for several mass mortality events involving marine birds and mammals. In all cases, the toxin was t

We challenged four species of copepod grazers (Acartia hudsonica, Centropages hamatus, Eurytemora herdmani, Calanus finmarchicus) with natural water samples containing non-toxic algae mixed with one of three clones of Alexandrium spp.—A. tamarense

Zooplankton can consume toxic Alexandrium spp. dinoflagellates in the Gulf of Maine and retain paralytic shellfish poisoning (PSP) toxins, potentially acting as toxin vectors. We performed experiments to determine toxin budgets for common species of

Temporal variability in the distribution and abundance of North Atlantic right whales Eubalaena glacialis and their copepod prey, late-stage Calanus finmarchicus, was monitored at an oceanographic station in Grand Manan Basin of the lower Bay of Fund

The seriously endangered north Atlantic right whale ( Eubalaena glacialis ) is regularly exposed to the neurotoxins responsible for paralytic shellfish poisoning (PSP) through feeding on contaminated zooplankton acting as a vector of these dinoflagel

Development rates, nitrogen- and carbon-specific growth rates, size, and condition were determined for the copepod Calanus finmarchicus reared at 3 temperatures (4, 8, and 12°C) at non-limiting food concentrations and 2 limiting food concentrations

Laboratory experiments suggest that toxic Alexandrium spp. cells are unpalatable to zooplankton grazers, and that toxic cells should be selectively avoided by zooplankton when feeding in mixtures of different prey species. Such avoidance, if practise
