Pamela C. Rasmussen at work at the Smithsonian Institution

Pamela Cecile Rasmussen (born October 16, 1959 ) is an American ornithologist and expert on Asian birds . She initially worked as a research fellow at the Smithsonian Institution in Washington, DC and now teaches at Michigan State University . It cooperates with many research centers in the USA and Great Britain.

In her first research, Rasmussen studied South American sea ​​birds as well as fossil birds from North America. She later specialized in Asiatic birds, describing several new species and clarifying the status of others, particularly spectacled birds and owls . Most recently, she participated in large research projects on patterns in global biodiversity and examined the taxonomic status of South Asian vultures .

Rasmussen is the lead author of Birds of South Asia: The Ripley Guide , which is considered the standard work for its extensive coverage of the area and the species it covers. While studying bird skins in the museum for this book, she managed to reveal the extent of the thefts and forgery of documents committed by the respected British ornithologist Richard Meinertzhagen .

Life

Pamela Rasmussen is the daughter of Helen Rasmussen, a Seventh-day Adventist whose husband left the family when Pamela and her sisters were young. She became interested in birds when her mother gave her the youth edition of Oliver Austin's Birds of the World . After that, Pamela only wanted bird books as a present.

In 1983 she completed her Masters at the Walla Walla University , the Seventh-day Adventist university in the southeast of the State of Washington , and was in 1990 at the University of Kansas with a study on a group of cormorants ( blue-eyed shags doctorate). It was in Kansas that she was first confronted with the theory of evolution , which had not been taught at her home university.

Rasmussen is an assistant professor of zoology and assistant curator of mammals and ornithology at the University of Michigan State. Previously, she was a research assistant of the famous American ornithologist S. Dillon Ripley at the Smithsonian Institution in Washington, DC She is a member of the Committee for Classification and nomenclature of the American Ornithologists' Union (AOU), scientific advisor to the Bird Working Group of the British Natural History Museum in Tring and co-editor of The Ibis , the scientific journal of the British Ornithologists' Union . Pamela Rasmussen is with Dr. Michael D. Gottfried, curator of paleontology, adjunct professor of geology and director of the Center for Integrative Studies in General Science at the University of Michigan State.

South American sea birds

In her early work, Rasmussen focused on the systematics , ecology and behavior of Patagonian sea ​​birds, especially cormorants. She studied plumage variants in juvenile blue-eye , wart and pied shags and used plumage and behavioral patterns to determine a relationship between wart and blue-eye shags. She also investigated the fishing activities of the olive shag .

Asiatic birds

Drawing of the Blewitt owl from 1891, which was rediscovered by Rasmussen in 1997

Through her study of museum specimens, Pamela Rasmussen succeeded in describing four new Asian bird species: in 1998 the Nicobar scops owl Otus alius , the Sangihe scops owl Otus collari and the cinnabar owl Ninox ios , which is endemic to Sulawesi, and in 2000 the Taiwanese shrimp singer Bradypterus alishanensis . In western India she rediscovered the blewitt owl Athene blewitti , who had not been sighted since 1884 after S. Dillon Ripley, Sálim Ali and others had failed because of the forged documents by Richard Meinertzhagen . In November 1997, Rasmussen and Ben King of the American Museum of Natural History searched in vain for ten days in two locations in eastern India before heading west to the location of another, long-lost species, where King a small, compact owl with short, white-feathered legs and large claws. Rasmussen confirmed the species while they were filming and photographing the owl.

She and her colleagues clarified the taxonomy of Indonesian glasses birds , established the Sangihe-Brillenvogel Zosterops nehrkorni and Seram-Brillenvogel Z. stalkeri as distinct species, and confirmed the identity of the Serendib-Zwergohreule that in Sri Lanka from the local Ornithologen Deepal Warakagoda discovered had been.

The Togian spectacled bird Zosterops somadikartai was identified as a new species by Rasmussen and her colleagues in 2008

The Imperial Pheasant is a rare bird found in the forests of Vietnam and Laos. Rasmussen and her colleagues used morphology , hybridization experiments and DNA analyzes to show that this pheasant , previously thought to be threatened, is actually a naturally occurring hybrid between the Vietnam pheasant Lophura hatinhensis and the subspecies annamensis of the silver pheasant L. nycthemera .

In 2008 she turned back to the taxonomy of the spectacled bird with a scientific description of the Togian spectacled bird Zosterops somadikartai . The species endemic to the Indonesian Togian Islands - unlike most of its relatives - lacks the white ring around the eye that gave this group of birds its name. Rasmussen also noticed that the Togian spectacled bird differs not only in its appearance, but also in its warbling song, which has a higher frequency and a lower frequency range than the song of its close relatives.

The Indian vulture, an endangered species that was split off as a result of Rasmussen's research on the genus Gyps

Pamela Rasmussen's interest in Asian birds led her to get involved in nature conservation projects. Two of the Old World vultures belonging Gyps species, the white-rumped vulture Gyps bengalensis and the Long-billed Vulture were in South Asia by the veterinary use of diclofenac declined by 99 percent. The drug induced kidney failure in birds that ate from the carcasses of treated cattle. Rasmussen showed that there are two different species of Long-billed Vulture : the Indian vulture Gyps indicus and the narrow -billed vulture G. tenuirostris . This is important for nature conservation as a human-cared breeding program has been set up to help these endangered vulture species recover.

biodiversity

In 2005 Rasmussen took part in a large project by several institutions on regions with high, severely threatened biodiversity ( hotspots ), which play an important role in nature conservation. The study assessed the regions according to three criteria of bird diversity: species richness, the degree of threat and the number of endemic species. The results showed that the hotspots were not evenly distributed according to each of these criteria. Only 2.5 percent of the hotspot areas correspond to all three of these criteria, 80 percent of the hotspots only meet one criterion. Each criterion explained less than 24 percent of the variation in the other factors, suggesting that even within the same taxonomic group, different mechanisms are responsible for the creation and maintenance of different aspects of biodiversity. As a result, the different types of hotspots are differently suitable for nature conservation .

Most recently, Rasmussen worked in other large projects at the same institutions in which the global patterns of biodiversity are studied. An overview of the species richness and the geographical extent of the distribution areas did not show the expected decrease in the size of the distribution areas from the temperate zones to the tropics. Although this pattern applied largely to the northern hemisphere, it did not seem to apply to the southern hemisphere. Research on the relationship between extinction and human influence, after species richness was standardized, showed that human influence best predicts global patterns of extinction risk and that ecological factors are only of secondary importance. A study of the distribution of rare and endangered vertebrate species showed different patterns for birds, mammals and amphibians, which has consequences for nature conservation strategies based on the hotspot concept.

Other studies by Rasmussen and her international colleagues have been devoted to the importance of food availability. A 2007 study showed that global patterns of species change are driven more by widespread rather than spatially limited species. This complements other research and helps build a unified model of how terrestrial biodiversity varies within and between the world's large land areas.

paleontology

A fossil pit near Cheswold , Delaware , which was created during road works, yielded eleven specimens of fragmented bird fossils, which Rasmussen identified as a small loon , a small gull- like species, and five specimens of a gannet - like sea bird - probably Morus loxostylus , a common species of the Miocene - was identified. All of these forms were already known from a site in Chesapeake Bay , Maryland . The findings suggest that the Delaware site was near a large bay at the time of fossilization.

Rasmussen was also involved in studying fossil birds from Pliocene and Miocene deposits from North Carolina . Among the finds include a miozänischer loons Colymboides minutus and a member of the genus Corvus ( crows and ravens ), one of the few fossils of passerine birds that are known from this period. The study came to the conclusion that fossil birds from this period generally resemble a recent species or genus, and those for which this is not the case can usually be well placed in a recent family .

Birds of South Asia

1992 Rasmussen was the assistant to S. Dillon Ripley become, the former managing director ( secretary ) of the Smithsonian , who was planning a definitive Guide to the Birds of South Asia. Ripley fell ill shortly after the project began, Rasmussen took it over and produced, together with graphic artist John C. Anderton, Birds of South Asia: The Ripley Guide . The two-volume bird guide for the Indian subcontinent was the first identification book for this area to contain sonagrams . Volume 1 includes the identification book with over 3400 illustrations on 180 plates and more than 1450 color cards. Volume 2 ( Attributes and Status ) contains the measurements, data for identification, status, distribution and habitats. The vocalizations are described on the basis of recordings with over 1000 sonograms.

1508 species that occur or have occurred in India, Bangladesh , Pakistan , Nepal , Bhutan , the Maldives , the Chagos Archipelago and Afghanistan are treated, including 85 hypothetical and 67 'possible' species, which are only briefly described. Birds of South Asia is remarkable for its data base - the authors based the information on distribution almost exclusively on museum specimens - and its taxonomic approach with numerous breakdowns of species. The geographical coverage is also greater than in earlier studies, mainly because Afghanistan was taken into account.

Many allopatric forms that were previously considered to belong to one species are treated as full species by Rasmussen and Anderton. Most of them had been suggested elsewhere, but the book introduced an innovation here. Asiatic bird experts, Nigel J. Collar and John Pilgrim , analyzed in 2008 the changes proposed by Rasmussen and Anderton, highlighting changes previously suggested by other authors, which were new and which require further investigation.

Although the reviews in the specialist and hobby ornithological press were often favorable, there were also critical voices. Peter R. Kennerley , an expert on Asian birds, thought some of the illustrations were too small, garish, or inaccurate. He also believes that relying on museum specimens, sometimes very old, and not using the rich observational data obtained from traveling hobby ornithologists, is a mistake. In his view, many taxonomic decisions have been made arbitrarily and are not covered by the research literature.

Aside from the Meinertzhagen scam described in the next section and the death of S. Dillon Ripley, other problems in the production of Birds of South Asia were the loss of the main database for the maps during a trip to Myanmar and poorly groomed Bird hides. There were also difficulties in reconciling the sources, obtaining data for "difficult" areas such as Assam , Arunachal Pradesh , Bangladesh and Afghanistan, and delays in the production of illustrations and maps. The Andaman and Nicobar Islands also presented a serious problem with the status and taxonomy of their bird fauna.

Rasmussen discussed in a 2005 article whether the revision of the taxonomy in this book, with its frequent splitting of species, would have a major impact on conservation efforts, but suggested that the impact on biodiversity in South Asia would be limited. Nature conservation is also only affected to a limited extent because the proportion of potentially threatened species in the region has risen from six to seven percent of the total bird fauna.

The Meinertzhagen fraud

Rasmussen revealed the true extent of the great fraud committed by the distinguished British soldier, ornithologist and bird lice expert, Colonel Richard Meinertzhagen . Meinertzhagen, who died in 1967, was the author of numerous taxonomic and other works on birds and owned a huge collection of birds and bird lice. He was considered one of the most important British ornithologists. However, the British ornithologist Alan G. Knox had already examined Meinertzhagen's bird collection at the Walter Rothschild Zoological Museum in Tring in the early 1990s and discovered a considerable amount of fraud, including the theft of museum specimens and the falsification of accompanying documentation.

The blue flycatcher Cyornis banyumas is a species whose documentation was forged by Meinertzhagen

In preparation for Birds of South Asia , Rasmussen examined tens of thousands of bird skins, as the late S. Dillon Ripley had preferred to use museum specimens to identify the birds to consider. Together with Robert Prys-Jones from the Natural History Museum , she showed that the deception that Meinertzhagen had committed decades ago was far more extensive than initially thought. Many of the 20,000 bird skins in his collection had been given new labels, which indicated a new place of origin, and they were occasionally also newly prepared. The wrong documentation delayed the rediscovery of the Blewitt owl, as previous searches were based on Meinertzhagen's falsified information. Rasmussen's successful expedition ignored this information and led to areas from which other, unadulterated specimens came.

Meinertzhagen had been banned from using the Natural History Museum's bird room for 18 months because he had taken unauthorized specimens with him. The suspicion that he was stealing bird hides and literature from the library had been voiced by staff for over 30 years and had twice led to formal investigations.

False documents that have been identified by Rasmussen and Prys-Jones, the occurrence at high altitudes of concerned Pomatorhinus ferruginosus , the presence outside the known distribution area of Kaschmirzwergschnäppers Ficedula subrubra and the evidence of Muscicapa ferruginea and Cyornis Banyumas (formerly C. magnirostris ) in the Himalayas during the winter. On the other hand, some evidence, such as for Montifringilla theresae - a species Meinertzhagen described - appears to be genuine.
