Scientific collections:Stronger in developed countries thanks to strategies to send collectors that became foreign residents in Neotropical countries
Scientific Collections: Scientific Collections: different kind of specimensdifferent kind of specimens
Frozen bird tissue collections:began in 1973(photos from the University of Alaska Museum and the cryobats for tissues in liquid nitrogen of the American Museum of Natural History in New York)
Considerations for ABBI as a biodiversity infrastructure iniciative:
Independent vouchers of barcode sequences
Proper vouchers:scientific specimens prepared according to professional standards and accessioned into systematic collections
Feathers or digital images without vouchered specimens are of less quality and weak for infrastructure.
Migratory movements in neotropicalbirds are not well identified yet, so vouchers and breeding individuals forbarcoding are priority. Without themquestionable “cryptic” species couldbe indentified
Independent vouchers of barcode sequences
high quality vouchers are preferably breeding-locality specimens accessioned into publicly available scientific collections that appropriately preserve diagnostic features of taxa and carry full specimen data (e.g. collecting locality, date, collector, soft-part colors, body mass).
Legal documentation of specimen provenance
With the Convention of Biological Diversity countries obtained jurisdiction over biodiversity resources within their frontiers
Legal documentation of specimen provenance
Scientific collections have decades of experience following these regulations
Long term archival preservationof tissues and DNA extracts
Archival preservation of tissues and DNA extracts(protocols)
tissues in liquid nitrogen
purified DNA samples should be housed at the institutions where the specimen vouchers and raw sample tissues are housed,
or minimally in an institution that is equiped to house DNA extract collections, with a clear linkage back to the original voucher specimen and associated data
Distributed structure/community effort
Data and samples should be retained by institutions that house the permanent voucher specimens
Distributed structure/community effort
Scientific literature
Primary Species’ Occurrence Data
Recordings, images, videos
Field notes, otherancillary information
Stomach contents, etc.
Geospatial datadescribing locality
Parasites etc.
Stable isotope data
Gene sequence dataGenomics
Remote-sensingdata showing
locality in space and time
Taxonomic data
5 000,000 specimens will be reachable from more that 40 institutions
Distributed structure/community effort
distributed database of museum specimens and observational database
the raw data is always refered to the owner institution as providers
Distributed structure/community effort
Sampling design
Museum-based systematists and other ornithological researchers could embrace ABBI as an opportunity to create a coordinated network of tissue collections and DNA extracts of all avian species.
In conclusion
ABBI potential for learning about bird systematics –species limits, species identifications, molecular sequence variation, and phylogenies
necessary cooperation from the museum community for strategies with a long term, archival, and distributed point of view.
protocols that recognize the basic tenents of systematics (e.g. repeatability, vouchering)
Acknowledgement for the decades-long effort of the critical tissue collections that can contribute to this collegiate effort
Opportunity for joint fund raising efforts to develop high quality storage conditions for tissue collections and vouchers in megabiodiversity countries institutions
