www.chrysophytes.eu - a database on distribution and ecology of silica-scaled chrysophytes in Europe
Abstract
Members of the silica-scaled chrysophytes are important components of the freshwater phytoplankton. Knowledge of the occurrence of chrysophytes and of their ecological ranges can be useful for many types of studies, for example for monitoring water quality or for paleolimnological and biogeographical studies.
An internet database of the European silica-scaled chrysophytes has been developed to store microphotographs and sampling data (including geographical coordinates, pH, conductivity and temperature values), and to provide access to the data to all people who are interested. The database currently includes data from almost 170 published papers and holds information about the distribution and ecology of 194 species, based on more than 7000 entries.
For each species listed in the database, a photo gallery, a list of all records, and a distribution map are provided, and are automatically updated with each new entry. For those species with more than 20 records, their distribution frequencies in relation to gradients in pH, conductivity, and temperature are also shown.
Continual addition of newly published and as yet unpublished data is planned. Join us and insert your own records or EM photographs from Europe into the database!
