Linnaeus II is an innovative multifunctional research tool for systematists and biodiversity researchers, facilitating biodiversity documentation and species identification.

Linnaeus II was developed by ETI BioInformatics at the University of Amsterdam, the Netherlands. The software package, available for both Windows and Mac OS X, allows the creation of taxonomic databases, optimizes the construction of easy-to-use identification keys, expedites the display and comparison of distribution patterns, and promotes the use of taxonomic data for biodiversity studies.

The software can also be used to publish completed information systems on CD-ROM / DVD-ROM or make them available on the Web.



Currently product reviews are in preparation within the EDIT project. You can download and try a demo version of Linnaeus II 2.5 yourself (provides the same functionality as version 2.6).

This fully functional demo is based on the Arthropods of Economic Importance - Eurasian Tortricidae CD-ROM, which exploits the entire feature set of Linnaeus II. The program uses three types of keys (Text Key, Picture Key and IdentifyIt), both types of taxonomic databases (Species and Higher Taxa), all supporting modules (Glossary, Introduction, Literature, Index, plus a custom module called Hosts) and the geographical module MapIt. Use the link below to go to the download page of the Linnaeus II demo of your choice:
