Ecological and Biogeographical Inferences on Two Sympatric and Enigmatic Andean Cat Species Using Genetic Identification of Faecal Samples
Constanza Napolitano,Magdalena Bennett,Warren E. Johnson,Stephen J. O'Brien,Pablo A. Marquet,Pablo A. Marquet,Iván Barría,Elie Poulin,Agustín Iriarte +8 more
TL;DR: In this article, the authors determined the origin of 186 carnivore samples (184 faeces and two skulls) collected above 3000 m above sea level in northern Chile, including 33 from the Andean mountain cat and 75 from the pampas cat using diagnostic molecular genetic sequence variation.
Journal ArticleDOI
Sympatric Asian felid phylogeography reveals a major Indochinese–Sundaic divergence
Shu-Jin Luo,Yue Zhang,Warren E. Johnson,Lin Miao,Paolo Martelli,Agostinho Antunes,James L. Smith,Stephen J. O'Brien,Stephen J. O'Brien +8 more
TL;DR: Results illuminate unexpected, deep vicariance events in Southeast Asian felids and provide compelling evidence of species‐level distinction between the Indochinese and Sundaic populations in the leopard cat and marbled cat.
Journal ArticleDOI
The developmental anatomy of the neonatal glenohumeral joint.
TL;DR: It is indicated that some of the important functional elements of the structure of the mature human shoulder are present early in development, including the glenohumeral and coracoacromial ligaments.
Journal ArticleDOI
Association of Polymorphisms in Human Leukocyte Antigen Class I and Transporter Associated with Antigen Processing Genes with Resistance to Human Immunodeficiency Virus Type 1 Infection
Chenglong Liu,Mary Carrington,Richard A. Kaslow,Xiaojiang Gao,Charles R. Rinaldo,Lisa P. Jacobson,Joseph B. Margolick,John P. Phair,John P. Phair,Stephen J. O'Brien,Roger Detels +10 more
TL;DR: It is suggested that differential preferences for amino acids at the C terminus may influence peptide-binding capacity, and TAP2 Ala665 was associated with resistance to HIV-1 infection, perhaps because of its higher efficiency in transporting peptides, thus eliciting a greater CD8(+) T cell response, or because of linkage disequilibrium.
Journal ArticleDOI
Subspecies Genetic Assignments of Worldwide Captive Tigers Increase Conservation Value of Captive Populations
Shu-Jin Luo,Shu-Jin Luo,Warren E. Johnson,Janice S. Martenson,Agostinho Antunes,Agostinho Antunes,Paolo Martelli,Olga Uphyrkina,Kathy Traylor-Holzer,James L. Smith,Stephen J. O'Brien +10 more
TL;DR: Assessment of verified subspecies ancestry offers a powerful tool that, if applied to tigers of uncertain background, may considerably increase the number of purebred tigers suitable for conservation management.
