How to use Algaevision
AlgaeVision is a searchable digital catalogue of 2,300 images of nearly 250 genera, 680 species and about 80 intraspecific taxa of British and Irish freshwater and subaerial algae. The catalogue was compiled and edited by David John, Jo Wilbraham and Chris Carter. It is intended to be used in conjunction with the second edition of The Freshwater Algal Flora of the British Isles (2011). Each taxonomic entry is accompanied by the page number for the relevant description and illustrations (typically line drawings) in the book.
Entries are listed according to the taxonomic name given in the second edition of the aforementioned book or the currently accepted name if this has uperseded it. (A list of nomenclatural changes since 2011 can be found here). Both names are included in the taxonomic hierarchy.
Taxa can found by expanding the taxonomic hierarchy or located directly using the search field at top of the page. Each image entry includes:
- the currently accepted name
- details of the author or authors of the name
- dimensions, unless a scale bar is provided
- the photograph type (e.g. brightfield, differential interference contrast, phase contrast or anaglyph)
- details of the copyright holder
- collection information, if known
- taxonomic or other comments
- the page and plate number for the taxon in the second edition of The Freshwater Algal Flora of the British Isles
A new feature is a link to AlgaeBase, a regularly updated electronic publication providing current information on the algal taxonomy, nomenclature and world distribution.
Unlike the first version of AlgaeVision, entries are not accompanied by a unique eight-digit code number since these are now freely downloadable from the Centre for Ecology and Hydrology website.
