All Birds Barcoding Initiative (ABBI) goal:create DNA barcode library for world birds
Why barcode birds? Practical tool for specimen identification • Bird strike remains • Non-breeding or juvenile forms in banding operations • Products from endangered species Help speed discovery of new species • Many undiscovered bird species are lurking in museum drawers • DNA barcode testing of museum specimens is relatively fast, • cheap way to flag genetically divergent specimens Insight into mitochondrial evolution and population biology • Avian taxonomy combined with standardized mtDNA • analysis is a powerful tool for exploring biology underlying • genetic differences within and among species • Limited intraspecific variation supports emerging view that • recurrent selective sweeps prune genetic diversity
Target: 9,933 bird species1Organization: 6 regional working groupsParticipants: 60 researchers, 32 countries Map adapted from The Speciation and Biogeography of Birds, Newton, 2003 • ABBI target list based on The Clements Checklist of Birds of the World, 2007
Resources: 70% of world birds are in frozen tissue collections (>240,000 specimens representing 6,853 species) Access to tissues and restrictions on transport of specimens may be limiting New collecting and non-tissue museum holdings (10 million avian skins, bones, etc) to help fill in gaps These approaches are more expensive, slower Feather or blood samples from live birds Photographs as e-vouchers in reference database?
September 2007: 10,000 barcodes from 2,080 species (21% world birds) Goal: 100,000 barcodes from 10,000 birds
