Gross intestinal morphometry and allometry in primates (e23035)
Although it is generally assumed that among mammals and within mammal groups, those species that rely on diets consisting of greater amounts of plant fiber have larger gastrointestinal tracts (GIT), statistical evidence for this simple claim is largely lacking. We compiled a dataset on the length of the small intestine,...McGrosky, Amanda ; Meloro, Carlo ; Navarrete, Ana ; Heldstab, Sandra A ; Kitchener, Andrew C …

Frozen assets saving species with biobanks
How do frozen tissue samples from the 1960s help animal conservation in the time of COVID-19? Andrew Kitchener and Gill Murray-Dickson explore the importance of our Biobank and the CryoArks initiative for continuing research to answer the questions of today and the future.Kitchener, Andrew C

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Javan tiger (P.t. sondaica), Balinese tiger (P.t. balica), and Caspian tiger (P.t. virgata), including previously unpublished specimens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