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

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Javan tiger (P.t. sondaica), Balinese tiger (P.t. balica), and Caspian tiger (P.t. virgata), including previously unpublished specimens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 …

Geographical variation in the clouded leopard, Neofelis nebulosa, reveals two species instead of one
The clouded leopard, Neofelis nebulosa, is an endangered semiarboreal felid with a wide distribution in tropical forests of southern and southeast Asia, including the islands of Sumatra and Borneo in the Indonesian archipelago . In common with many larger animal species, it displays morphological variation within its wide geographical range...Kitchener, Andrew C ; Beaumont, Mark A. ; Richardson, Douglas

New Bornean carnivore’ is most likely a little known flying squirrel
We analysed two camera-trap photos of an alleged new species of carnivore from Kalimantan, Borneo, Indonesia. Comparisons of the features seen in the photos with morphological features of 17 similar-looking species from the region suggest that the animal is not a new species of carnivore, as had been widely speculated,...Meijaard, Erik ; Kitchener, Andrew C ; Smeenk, Chris

Detecting the elusive Scottish wildcat Felis silvestris silvestris using camera trapping
Population monitoring is important for conservation management but difficult to achieve for rare, cryptic species. Reliable information about the Critically Endangered Scottish wildcat Felis silvestris silvestris is lacking because of difficulties in morphological and genetic identification, resulting from extensive hybridization with feral domestic cats Felis catus. We carried out camera-trap... -

Splitting or lumping? A conservation dilemma exemplified by the critically endangered Dama Gazelle (Nanger dama)
Managers of threatened species often face the dilemma of whether to keep populations separate to conserve local adaptations and minimize the risk of outbreeding, or whether to manage populations jointly to reduce loss of genetic diversity and minimise inbreeding. In this study we examine genetic relatedness and diversity in three...Senn, Helen ; Banfield, Lisa ; Wacher, Tim ; Newby, John ; Rabeil, Thomas …

Survey and scoping of wildcat priority areas
This report summarises the findings of three complementary projects commissioned by SNH to inform the selection of Priority Areas for wildcat conservation; as proposed in the Scottish Wildcat Conservation Action Plan 2013. The scoping projects combined field surveys, taxonomic and genetic assessments, population modelling and a questionnaire survey of public...Littlewood, N A ; Campbell, R D ; Dinnie, L ; Gilbert, L ; Hooper, R …

Late Holocene range collapse in a former British seabird species
Aim to determine the taxonomic identity of zooarchaeological gadfly petrel (Pterodroma) specimens from northern Europe, in order to investigate whether an unknown, now-extinct Pterodroma species formerly occurred in this region, or whether extant north-east Atlantic gadfly petrel populations now restricted to the Macaronesian Islands formerly had a much wider Holocene... -

Evidence of the three main clonal Toxoplasma gondii lineages from wild mammalian carnivores in the UK
Toxoplasma gondii is a zoonotic pathogen defined by three main clonal lineages (types I, II, III), of which type II is most common in Europe. Very few data exist on the prevalence and genotypes of T. gondii in the UK. Wildlife can act as sentinel species for T. gondii genotypes...Burrells, A ; Bartley, P M ; Zimmer, I A ; Roy, S ; Kitchener, Andrew C …

Brain size of the lion (Panthera leo) and the tiger (P-tigris): implications for intrageneric phylogeny, intraspecific differences and the effects of captivity
Intraspecific encephalization of the lion and the tiger is investigated for the first time using a very large sample. Using cranial volume as a measure of brain size, the tiger has a larger brain relative to greatest length of skull than the lion, the leopard and the jaguar. The Asian...Yamaguchi, Nobuyuki ; Kitchener, Andrew C ; Gilissen, E ; Macdonald, David W

The Near Eastern origin of cat domestication
The world's domestic cats carry patterns of sequence variation in their genome that reflect a history of domestication and breed development.

What is a tiger? Biogeography, morphology, and taxonomy
The tiger has always had a considerable impact on human cultures, especially where people and tigers have lived together and still do co-exist. It is certainly one of the most easily recognizable cats, with its distinctive and unique striped coat and is also commonly believed to be the biggest cat...Kitchener, Andrew C ; Yamaguchi, Nobuyuki

Taxonomic issues in bears: impacts on conservation in zoos and the wild, and gaps in current knowledge
Taxonomy is essential for underpinning conservation science and action, and the international and national implementation of protective legislation. However, many of the current scientific species and subspecies names for bears have a poor scientific basis. Poor understanding of ursid taxonomy could compromise conservation both in the wild and in captivity;...Kitchener, Andrew C
