Additionally, histopathological and stress responses (through heat-shock protein [hsp70] induction), as well as accumulation of Paralytic Shellfish Poisoning (PSP) toxins, were monitored on scallops after 3 and 6 days of exposure to A. catenella. The size of the cysts (length: 43-60 m; width: 22-25 m), presence of granular material and a red body were also very similar to these species. Laboratory experiments were designed to study the toxin content and profile of the Alexandrium catenella strain ACT03 (isolated from Thau Lagoon, French Mediterranean) in response to abiotic environmental factors under nutrient-replete conditions. 8600 Rockville Pike These protists are referred to as mixotrophs since they can both consume organisms/organic materials and perform photosynthesis in order to get food: It's a "mix" of both autotrophic and heterotrophic ability.

Leaf! However, Colin and Dam (Colin and Dam, 2003) found that the depression of feeding rate of copepods exposed to high concentration of Alexandrium fundyense could be alleviated if copepods were exposed to low concentrations of A. fundyense before the test, which indicates that the negative response of ephyrae exposed to high concentrations of A. catenella might be alleviated if ephyrae were acclimated to low concentration in the coastal waters. Los miembros del gnero forman una parte importante del plancton que se encuentra en los mares de zonas templadas, y se sabe que varios causan mareas rojas y floraciones de agua.
