by Appeltans, Ward
IISE counted 176,311 new living species between 2000 and 2009, of which 19,232 were described in the last year (SOS report 2011, released on 18 Jan 2012). WoRMS has 1,928 new marine species in 2009. The data were gathered from Zoological Record, IPNI, MycoBank, WoRMS and AlgaeBase.
This year's annual report, SOS 2011, summarizes the 19,232 new living species officially described in calendar year 2009 and includes animals, plants, algae, fungi and microbes. The Retro SOS provides a data summary of the 176,311 new living species that were discovered and described from 2000 to 2009. With a scope of 10 years, the Retro SOS allows a greater understanding of the data trends that reflect the successes, gaps, and opportunities of species exploration ? such as a notable 12.8% increase in new extant species descriptions for the time period.
