Prokaryotic Nomenclature Up-to-Date

"Prokaryotic Nomenclature up-to-date' is a compilation of all names of Bacteria and Archaea which have been validly published according to the Bacteriological Code since 1. Jan. 1980, and nomenclatural changes which have been validly published since. It will be updated with the publication of each new issue of the Int. J. Syst. Evol. Microbiol. (IJSEM).
'Prokaryotic Nomenclature up-to-date' is based on the work of N. Weiss and M. Kracht and is maintained by Dorothea Gleim who may be consulted on technical aspects (database resp. online access)."

Thesaurus of Terms Used in Microbial Risk Assessment

"Federal and international agencies, private sector organizations, and academics use terms and definitions differently in their microbial risk assessments. This Thesaurus is a compendium of risk assessment terms found in frameworks, methodologies, and assessments. It provides insight into how various entities use specific microbial risk assessment terms in their activities and helps those responsible for such assessments both conduct and communicate about them more effectively."

AlgaeBase Taxonomy

"You can browse though the hierarchy by clicking on the names below and drilling down. At each level the numbers of current species are given for each taxon. Only currently accepted names are currently included. Should you find any errors, please click on the little envelope icon, and you can send me an e-mail via the site. In order to make calculations of the numbers of species of living algae, note that 68 or so species of flowering plants (seagrasses) are included for the present (under the Phylum Magnoliophyta), and about 2000 fossil algae, mainly calcium- and silica- secreting forms.

Virus Taxonomy

"Taxonomy lies at the uneasy interface between biology and logic. The processing of information follows somewhat different rules in these two systems and the role of taxonomy is to reconcile them as tidily as possible. To this end, the Virology Division of the International Union of Microbiological Societies (IUMS) charged the International Committee on Taxonomy of Viruses (ICTV) with the task of developing, refining, and maintaining a universal virus taxonomy.
