Content

Here is some information on what are currently the policies and methodologies that drive AlgaeBase and its associated sites.

Inclusion of names

We are endeavouring to add as many names as possible to AlgaeBase, although in a number of instances no data are provided other than the names and the nomenclatural authorities. In other instances, the synonyms and current names and synonyms have not been connected up (and are labelled as "Provisional"). We think it important that searchers for names find them, and links are provided to GenBank, Index Nominum Algarum, and other sources that may provide additional information.

Organisms included

Marine, freshwater and terrestrial algae, although currently the data for marine organisms are the most complete. Blue-green algae (Cyanobacteria), rhodophytes, phaeophytes, chlorophytes, euglenophytes, charophytes, diatoms, dinoflagellates, cryptophytes are all treated, together with a number of smaller groups. For convenience, we have included sea-grasses, although these are flowering plants and not algae. One small point. The taxon Fungi appears in the Taxonomy Browser because of Mastodia, a genus of lichenized fungi first based on an Antarctic alga.

Data

Data on this site are based mainly on published information. This information should always be verified by you, the user, prior to use, as is the normal practice. Distributional data are recorded on the basis of the name used in the publication in question, and some of these names may be misapplied. We are annotating such records as we become aware of them, but these notes are not available just now.
