Proposed by Raunkiaer (1934), the system classifies plants according to forms used to protect their perennating buds during unfavorable seasons, and groups them into five main classes: therophytes, cryptophytes, hemicryptophytes, chamaephytes and phanerophytes, according to their different resistance strategies to environmental conditions.
Recent advances in the understanding of the physiology (including toxicity), ecology and evolution of the Dinophysiales species are and will be related to the success in culturing Dinophysis species in a three-stage system involving (1) cultivation of cryptophytes, (2) feeding them to ciliate prey Myrionecta rubra (Lohmann) Jankowski, and (3) feeding of the latter to the Dinophysis cells (Park et al., 2006; Nishitani et al., 2008; Tong et al., 2010).
In each case, the main photosynthetic algae comprised mainly Cryptophytes, whose dominance of the phytoplankton of Laguna de Guatavita had been noted previously by Orjuela (2004).

A similar situation was observed in the Sao Simao reservoir with phytoflagellate cryptophyte algae, mainly Cryptomonas erosa and C.

We assigned the life-form of each species with an identification key (Mueller-Dombois and Ellenberg, 1974), considering only Raunkiaer's major classes - phanerophytes, chamaephytes, hemicryptophytes, cryptophytes, and therophytes - and including lianas in the "phanerophyte" class and geophytes in the "cryptophyte" class, as originally proposed by Raunkiaer (1934).
Most phytoplankton organisms found at this site are very small forms, such as the Cryptophyte alga Rhodomonas minuta, whose abundance in summer varies between one million and six million cells per liter.

The life form spectra showed 31 (39.74%) therophytes, 17 (21.79%) megaphanerophytes, 12 (15.38%) cryptophytes, 11 (14.10%) nanophanerophytes, 5 (6.41%) hemicryptophytes and 2 (2.56%) chamaephytes (Table 2, Fig.
