DNA from a 100-Year-Old Specimen Confirms the Validity of a Potentially Extinct Hummingbird Species


by Gary Graves

Cataloguing the biota of biologically unexplored regions often follows closely on the heels of human population expansion and subsequent waves of anthropogenically caused extinctions. Many species that were rare when first encountered by biologists have not been observed since the specimens were collected. Species known only from unique specimens are rightfully viewed with caution because they may represent hybrids or aberrant phenotypes.

Living populations of these biological mysteries are occasionally 'rediscovered' in nature many decades after their scientific descriptions, providing hope to conservationists. More frequently, the mysteries remain unsolved, hinting at an unknown history of hybridization or of possible extinction. For these cases, ancient DNA (aDNA) methods provide the means for resolving disputes regarding the validity of species known only from unique holotypes.

In a recent paper in Biology Letters, Jeremy Kirchman (New York State Museum), Christopher Witt (University of New Mexico), Jimmy McGuire (University of California, Berkeley), and Gary Graves (National Museum of Natural History) used this approach to investigate the contentious case of a spectacular 100-year-old hummingbird specimen, the holotype and the only known specimen of the Bogotá Sunangel, Heliangelus zusii.

In 1947, Brother Nicéforo María presented a specimen he purchased in 1909 in Bogotá, Colombia, to Rodolphe Meyer de Schauensee at the Academy of Natural Sciences of Philadelphia. Meyer de Schauensee was perplexed by the specimen and solicited the opinions of many leading ornithologists of his day, including Alexander Wetmore, Secretary of the Smithsonian Institution. There was no consensus among the experts.

In 1993, Graves conducted an exhaustive analysis of plumage and morphology, comparing the specimen to all hummingbird taxa housed in several of the largest museums. Following a well-established method of hybrid diagnosis, he concluded that the specimen represented the only known example of a valid species, which he named H. zusii. This conclusion was controversial, in part, because the exact provenance of the specimen was unknown and because hummingbirds are known to hybridize extensively. Consequently, the validity of the taxon was doubted by many authorities.

Kirchman et al. used sequence data from fragments of several mitochondrial genes to confirm that the holotype of Heliangelus zusii represents a valid species, which is genetically well differentiated from taxa previously hypothesized to have given rise to the specimen via hybridization. Phylogenetic analyses place H. zusii as sister to a clade of mid- to high-elevation Andean species currently placed in the genera Taphrolesbia and Aglaiocercus. Heliangelus zusii, presumed extinct, has never been observed in nature by biologists. Kirchman et al. infer that the species occupied a restricted distribution between the upper tropical and temperate zones of the northern Andes and that it was most probably driven to extinction by deforestation during the 19th and early 20th century. This study demonstrates the feasibility of obtaining genetic material from nearly microscopic tissue samples from old museum specimens and suggests that aDNA methods could be used to resolve the taxonomy of dozens of avian taxa known only from type specimens.


Courses


The Smithsonian-Mason Global Conservation Studies Programs is offering a new graduate and professional course, Conservation Conflict Resolution, an intensive 10-day experiential training course addressing conservation conflicts, whether these are conflicts between people and wildlife or between people about wildlife or other natural resources. The course will be held May 13-22, 2010, at the Smithsonian Conservation Biology Institute, Front Royal, Virginia. This course teaches participants strategies for effectively addressing conservation-related conflict, including the role of neutrality in conflict prevention and reconciliation; conflict-resolving communication techniques; and applying conflict analysis and process models to develop real-life conflict resolution plans. The course fee is $2,500, which includes instruction and course materials plus all meals, lodging, and ground transport to/from Dulles Airport (IAD). Course participants earn Continuing Education Units. Graduate course credits are available for qualified applicants at additional cost through George Mason University. Visit www.conservationtraining.si.edu or contact zootraining@si.edu for additional information.


Scholarships


The Wilderness Society is now accepting applications for the 2010 Gloria Barron Wilderness Society Scholarship. This $10,000 scholarship is awarded annually to a graduate student in natural resources management, law or policy programs. The scholarship seeks to encourage individuals who have the potential to make a significant positive difference in the long-term protection of wilderness in North America. The award is made in support of research and preparation of a paper on an aspect of wilderness establishment, protection, or management. The work may apply to a particular landscape or it may address issues broadly. TWS strongly encourages proposals relating to climate change, as well as other topics regarding wilderness conservation. For more information and application instructions, please visit http://wilderness.org/content/gloria-barron-scholarship-guidelines. The application deadline is March 31, 2010.
