| Harmful algal blooms of Dinophysis are responsible for diarrheic shellfish poisoning in human consumers of contaminated mollusks after bioaccumulation of their toxins. Dinophysis is a mixotrophic organism, which sequesters chloroplasts from a unique prey Mesodinium rubrum to perform its own photosynthesis, itself mixotrophic and feeds a cryptophyte, Teleaulax amphioxeia. The relationship between these three organisms is fundamental to understand the distribution and bloom dynamics of Dinophysis. In a first study, the effects of temperature, irradiance and pH on physiological aspects of T. amphioxeia were determined using a full factorial design before assessing the effect of contrasting physiological states after acclimation to two light intensities of T.... |
