SOS – State of Observed Species
Rod PageArizona State University’s “International Institute for Species Exploration” has released it’s first State of Observed Species Report. It reports that 16,969 new species were discovered in 2006 (approximately 46 species per day). Not surprisingly, most are insects:

SOS have also published a list of the “top 10″ species described in 2007.

This list has attracted some comment at The Other 95%, Zooillogix, and Catalogue of Organisms.
These lists have implications for EOL. The report gives us a lower bound on the rate of new species description — EOL will need to be able to add at east 46 species pages a day just to keep pace with new discoveries, never mind what has already been described. It isn’t doing anything like this at present, and hence none of the species in the SOS top ten list are in EOL (most are already in Wikipedia, and all return at least some information in iSpecies).

First of all I would like to thank you for you excellent site.
And I would like to ask you, do you know where can I found the number of new species that were discovered during the years? How many in 2005, how many in 2004, etc’?
Thanks
