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.
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).
Rhodomonas minuta was the most abundant epipelic cryptophyte.
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.
In the N enclosures, within 2 wk of manipulation, a cryptophyte, Rhodomonas minuta Skuja, dominated the phytoplankton assemblage.
Riverine phytoplankton, consisting mostly of small-celled cryptophytes and diatoms (Sobczak et al.
Finally, free-living phytoplankton, including dinoflagellates, cryptophytes, diatoms, and prymnesiophytes, show no effect of lowered pH (within a range of ~7.
El-Ghareeb and Rezk (1989) provided evidence that therophytes acquire dominance in less saline and more sandy habitats, while cryptophytes and chamaephytes in more saline habitats.
The vegetation, thus affected, includes shrubs, geophytes, hemi- cryptophytes, and annuals.
We considered only the life-form categories originally proposed by Raunkiaer: phanerophytes, chamaephytes, hemicryptophytes, cryptophytes and therophytes.
