The annual top 10 new species announcement and issuance of the SOS report commemorate the anniversary of the birth of Carolus Linnaeus, who initiated the modern system of plant and animal names and classifications. The 300th anniversary of his birth on May 23 was celebrated worldwide in 2007. Last year marked the 250th anniversary of the beginning of animal naming.
There are an estimated 1.8 million species that have been described since Linnaeus initiated the modern systems for naming plants and animals in the 18th century. Scientists estimate there are between 2 million and 100 million species on Earth, though most set the number closer to 10 million.
The SOS report card summarizes the number of major pspecies.asu.edulant and animal species newly described for the most recent year of complete data. The majority of the 18,516 species described (named) in 2007 were invertebrate animals (75.6 percent), vascular plants (11.1 percent) and vertebrates (6.7 percent). This year's SOS report also includes data for prokaryotes (bacteria and Archaea) in addition to protists.
The State of Observed Species report and list of top 10 new species issued annually by ASU's International Institute for Species Exploration is part of its public awareness campaign to shine attention on biodiversity and the field of taxonomy. Last year's list and report are online at species.asu.edu.
An international committee of experts, chaired by Janine N. Caira of the University of Connecticut, selected the top 10 new species for this year's list.
