Species Selection

A preliminary list of target species and genera was compiled by participants in the 2007 Project Baseline meeting following rigorous debate and discussion to identify taxa that would be most valuable to archive. This list was refined to include closely related species and species that offered the best opportunity logistically to meet the goals of the collection.

Species in the final list have diverse attributes. The variety of life history traits represented within the collection (see table below) offers exciting opportunities for a wide range of studies.
