Dimorphism in cryptophytes--The case of Teleaulax amphioxeia/Plagioselmis prolonga and its ecological implications.

The article focuses on the plagioselmis prolonga is the haploid form of the diploid T. amphioxeia and describe the seasonal dynamics of these two life stages. It mentions that diploid T. amphioxeia dominates during periods of high dissolved inorganic nitrogen (DIN) and low irradiance, temperature, and grazing. It also mentions that dimorphic sexual life cycles might explain the success of this species by fostering high genetic diversity and enabling endurance in adverse conditions.
