Locating specimens of extinct tiger (Panthera tigris) subspecies: Javan tiger (P.t. sondaica), Balinese tiger (P.t. balica), and Caspian tiger (P.t. virgata), including previously unpublished specimens
Recent advances in multivariate statistics, and in ancient DNA techniques, have greatly increased understanding of tiger phylogeography. However, regardless of advances in analytical methodology, researchers will continue to need access to specimens for morphological measurements and sampling for genetic analysis. The tiger has become increasingly endangered, and out of the...Yamaguchi, Nobuyuki ; Driscoll, Carlos A ; Werdelin, Lars ; Abramov, Alexei V ; Csorba, Gabor …

The genetic legacy of the 19th-century decline of the British polecat: evidence for extensive introgression from feral ferrets
In the 19th century, the British polecat suffered a demographic contraction, as a consequence of direct persecution, reaching its lowest population in the years that preceded the First World War. The polecat is now recovering and expanding throughout Britain, but introgressive hybridization with feral ferrets has been reported, which could...Costa, M ; Fernandes, C ; Birks, J D S ; Kitchener, Andrew C ; Santos-Ries, M …

The role of cross-sectional geometry, curvature and limb posture in maintaining equal safety factors: A computed tomography study
The limb bones of an elephant are considered to experience similar peak locomotory stresses as a shrew. "Safety factors" are maintained across the entire range of body masses through a combination of robusticity of long bones, postural variation, and modification of gait. The relative contributions of these variables remain uncertain....Brassey, Charlotte A ; Kitchener, Andrew C ; Withers, P J ; Manning, Phillip L ; Sellers, William I
