Abstract

Diatoms (Bacillariophyceae) and dinoflagellates (Dinophyceae) are the most numerous group of periphyton communities. Because it's primary production and diversity affect multiple trophic links of the chain, and thereby on biodiversity, gives them a great deal of attention in scientific research. Each research paper on periphyton communities begins in the field, sampling of pre-selected substrate in habitats that are representative of the analysis area that we want to characterize by the trophic state or degree of biodiversity. Sampling can be on either natural or artificial substrates that have been in water for at least 3-5 weeks. Adequate sampling requires monitoring protocols for sampling, always makig sure that the sample is well marked, and the volume and surface area measured. When laboratory analyzes are using different methods, depending on the results of the survey that they want to get. For diatoms and dinoflagelate most well treated sample and make a permanent archive to be able to sample more detailed and longer-term study. As bioindicators, periphyton community has become the focus of interest of biologists around the world, so there you come to important understanding of the ecological condition of habitats in which direct contact is the man himself.
