Save all species -- moth lights a way? John Pickering, Discover Life, University of Georgia, Athens and Sam Houston State University, Huntsville, Texas http://www.discoverlife.org/who/Pickering,_John.html Inspired by Half-Earth--Our Planet's Fight for Life, in which E.O. Wilson calls for half the planet to be devoted to preserving nature, Discover Life has started 'Save All Species' (see discoverlife.org/saveallspecies). Our goal is to ensure that by 2050, the world has the scientific knowledge, environmental policies, protected areas, trained resource managers, technology, funding, and public support to protect species. Because the task of inventorying the world's biodiversity is huge and would take centuries at the current rate of study, we will study a dozen representative taxa to speed the selection of enough parks and protected areas to save all species, including rare and local endemics. Here we consider moths and results from Discover Life's Mothing project to understand how weather patterns, urbanization, latitude, and other factors affect moth communities. Since 2010, participants have photographed over 600,000 insects at study sites in the United States and Costa Rica, documenting nightly differences in the seasonal activity and abundance of 3,000 moth species. Our educational objective is to involve the public in all aspects of the project. As part of this we are developing Moth Math to teach students how to analyze real-time moth data. In partnership with the Moth Photographers Group, Discover Life now provides online identification guides to 12,000 moth species. For details see http://www.discoverlife.org/moth . Please join us.
