Early Eocene fossil illuminates the ancestral (diurnal) ecomorphology of owls and documents a mosaic evolution of the strigiform body plan
We describe a partial skeleton of a fossil owl (Strigiformes) from the early Eocene London Clay of Walton-on-the-Naze (Essex, UK). The holotype of Ypresiglaux michaeldanielsi, gen. et sp. nov. is one of the most complete specimens of a Palaeogene owl and elucidates the poorly known ecomorphology of stem group Strigiformes....Mayr, Gerald ; Kitchener, Andrew C

New fossils from the London Clay show that the Eocene Masillaraptoridae are stem group representatives of falcons (Aves, Falconiformes)
The Eocene taxon Masillaraptoridae includes long-legged, raptorial birds, the phylogenetic affinities of which are poorly resolved. Here, fossils from the London Clay of Walton-on-the-Naze (Essex, U.K.) are described, which corroborate the hypothesis that masillaraptorids are stem group representatives of the Falconiformes (falcons). Two partial skeletons are assigned to a new...Mayr, Gerald ; Kitchener, Andrew C

African and Asian leopards are highly differentiated at the genomic level
Leopards are the only big cats still widely distributed across the continents of Africa and Asia. They occur in a wide range of habitats and are often found in close proximity to humans. But despite their ubiquity, leopard phylogeography and population history have not yet been studied with genomic tools....Paijmans, Johanna L A ; Axel, Barlow ; Becker, Matthew S ; Cahill, James ; Fickel, Joerns …

High-quality carnivoran genomes from roadkill samples enable comparative species delineation in aardwolf and bat-eared fox
In a context of ongoing biodiversity erosion, obtaining genomic resources from wildlife is essential for conservation. The thousands of yearly mammalian roadkill provide a useful source material for genomic surveys. To illustrate the potential of this underexploited resource, we used roadkill samples to study the genomic diversity of the bat-eared...Allio, Rémi ; Tilak, Marie-Ka ; Scornavacca, Celine ; Avenant, Nico L ; Kitchener, Andrew C …

Improved diagnosis of foot osteoarthritis in elephants ( elephas maximus, loxodonta africana) using stereoradiography
Diagnosis of foot disease in elephants is challenging. Owing to their large size, the available diagnostic tools and the expense of imaging are diagnostically limiting. Stereoradiography is the preparation of paired radiographs that form a three-dimensional (3D) image when viewed stereoscopically. Clinicians and veterinary students graded osteoarthritis in the feet...Bentley, Charlotte E ; Cracknell, Jonathan M ; Kitchener, Andrew C ; Martinez Pereira, Yolanda ; Pizzi, Romain

Selection preferences for animal species used in bone-tool-manufacturing strategies in KwaZulu-Natal, South Africa
Animal symbolism is a prominent feature of many human societies globally. In some cases, these symbolic attributes manifest in the technological domain, influencing the decision to use the bones of certain animals and not others for tool manufacture. In southern Africa, animals feature prominently in the cosmogenic narratives of both...Bradfield, Justin ; Kitchener, Andrew C ; Buckley, Michael

Abnormal (Hydroxy)proline Deuterium Content Redefines Hydrogen Chemical Mass
Analyzing the δ2H values in individual amino acids of proteins extracted from vertebrates, we unexpectedly found in some samples, notably bone collagen from seals, more than twice as much deuterium in proline and hydroxyproline residues than in seawater. This corresponds to at least 4 times higher δ2H than in any...Gharibi, Hassan ; Chernobrovkin, Alexey L ; Eriksson, Gunilla ; Saei, Amir Ata ; Timmons, Zena …

Genetic examination of historical North Atlantic right whale (Eubalaena glacialis) bone specimens from the eastern North Atlantic: Insights into species history, transoceanic population structure, and genetic diversity
Species monitoring and conservation is increasingly challenging under current climate change scenarios. For the North Atlantic right whale (Eubalaena glacialis) this challenge is heightened by the added effects of complicated and uncertain past species demography. Right whales once had a much wider distribution across the North Atlantic Ocean, although the...Frasier, Brenna A ; Springate, Leah ; Frasier, Timothy R ; Brewington, Seth ; Carruthers, Martin …

Cranial volume and palate length of cats, Felis spp., under domestication, hybridization and in wild populations
Reduced brain size, compared with wild individuals, is argued to be a key characteristic of domesticated mammal species, and often cited as a key component of a putative ‘domestication syndrome’. However, brain size comparisons are often based on old, inaccessible literature and in some cases drew comparisons between domestic animals...Lesch, Raffaela ; Kitchener, Andrew C ; Hantke, Georg ; Kotrschal, Kurt ; Fitch, W Tecumseh

Towards resolving taxonomic uncertainties in wolf, dog and jackal lineages of Africa, Eurasia and Australasia
Successful conservation depends on accurate taxonomy. Currently, the taxonomy of canids in Africa, Eurasia and Australasia is unstable as recent molecular and morphological studies have questioned earlier phenetic classifications. We review available information on several taxa of Old World and Australasian Canis with phylogenetic uncertainties (namely, African jackals, Asian wolves...Krofel, M ; Hatlauf, J ; Bogdanowicz, W ; Campbell, L A D ; Godinho, R …
