For instance, the solute-supported meromixis and the tendency to precipitate carbonate, even the dominance of cryptophytes in the stable part of the water column, and are similar to the features now recognized in Laguna de Guatavita.

The majority of taxa associated with Ageratina luciae-brauniae and/or Solidago albopilosa are phanerophytes (40%) or hemicryptophytes (36%); 2% are chamaephytes, 13% are cryptophytes, and 9% are therophytes.
Other small fast-growing, edible algae, such as most cryptophyte species, responded negatively to the nutrient and fish additions.

It was found that diatoms dominated phytoplankton biomass at all times (typically 50% or more of total phytoplankton biomass) followed by green algae (20 to 30%), cyanobacteria (10 to 20%), and cryptophytes (<10%).
Riverine phytoplankton, consisting mostly of small-celled cryptophytes and diatoms (Sobczak et al., 2002; Piirsoo et al., 2007), the latter often originating in periphyton, are easily assimilated by aquatic invertebrates, especially collector-gatherers and filter feeders (Webster et al., 1999).
Finally, free-living phytoplankton, including dinoflagellates, cryptophytes, diatoms, and prymnesiophytes, show no effect of lowered pH (within a range of ~7.0-8.5) on growth rates (Berge et al., 2010), emphasizing the lack of algal growth sensitivity to high pC[O.sub.2] exposure.
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.
