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

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

Dental Anomaly Causing Severe Maxillary Lesions in a Male Sowerby’s Beaked Whale (Mesoplodon bidens Sowerby, 1804)
Sowerby’s beaked whale (Mesoplodon bidens) is a poorly known cetacean species, and much of our current information comes from stranded animals. Herein, we describe a dental anomaly in an adult male stranded in 2019 in the Moray Firth, Scotland. The mandibular teeth (tusks) had erupted so their tips converged towards...Plint, Tessa ; Hantke, Georg ; Schwarz, Tobias ; Kitchener, Andrew C

Skull morphology diverges between urban and rural populations of red foxes mirroring patterns of domestication and macroevolution
Human activity is drastically altering the habitat use of natural populations. This has been documented as a driver of phenotypic divergence in a number of wild animal populations. Here, we show that urban and rural populations of red foxes (Vulpes vulpes) from London and surrounding boroughs are divergent in skull...Parsons, K J ; Rigg, Anders ; Conith, A J ; Kitchener, Andrew C ; Harris, S …

Population fragmentation leads to morpho-functional variation in British red squirrels (Sciurus vulgaris)
It is well-known that population fragmentation and isolation can lead to rapid morphological and functional divergence, with the effect being particularly well-documented in rodents. Here, we investigated whether such a phenomenon could be identified in the Eurasian red squirrel (Sciurus vulgaris), which was once widespread across the majority of Great...Cox, Philip G ; Morris, Philip J R ; Kitchener, Andrew C

Diets of European polecat Mustela putorius in Great Britain during fifty years of population recovery
Following nineteenth-century declines, polecats Mustela putorius are recolonising Great Britain. Polecat diet relates to two potential risks to recovery. First, rabbits Oryctolagus cuniculus, which are important prey for polecats, have experienced extreme population fluctuations, with near extirpation due to myxomatosis in the 1950s, recovery in 1960s–1990s and declines in 1990s–2010s....Sainsbury, Katherine A ; Shore, Richard F ; Schofield, Henry ; Croose, Elizabeth ; Hantke, Georg …

Applying genomic data in wildlife monitoring: Development guidelines for genotyping degraded samples with reduced single nucleotide polymorphism panels
The genomic era has led to an unprecedented increase in the availability of genome‐wide data for a broad range of taxa. Wildlife management strives to make use of these vast resources to enable refined genetic assessments that enhance biodiversity conservation. However, as new genomic platforms emerge, problems remain in adapting...von Thaden, Alina ; Nowak , Carsten ; Tiesmeyer, Annika ; Reiners, Tobias E ; Lyons, Leslie A …

Range-wide patterns of human-mediated hybridisation in European wildcats
Hybridisation between wild taxa and their domestic congeners is a significant conservation issue. Domestic species frequently outnumber their wild relatives in population size and distribution and may therefore genetically swamp the native species. The European wildcat (Felis silvestris) has been shown to hybridise with domestic cats (Felis catus). Previously suggested...Tiesmeyer, Annika ; Ramos, Luana ; Lucas, José Manuel ; Steyer, Katharina ; Alves, Paulo C …

Distinguishing the victim from the threat: SNP‐based methods reveal the extent of introgressive hybridization between wildcats and domestic cats in Scotland and inform future in situ and ex situ management options for species restoration
The degree of introgressive hybridization between the Scottish wildcat and domestic cat has long been suspected to be advanced. Here, we use a 35‐SNP‐marker test, designed to assess hybridization between wildcat and domestic cat populations in Scotland, to assess a database of 295 wild‐living and captive cat samples, and test...Senn, Helen ; Ghazali, Muhammad ; Kaden, Jennifer ; Barclay, David ; Harrower, Ben …

Long-term increase in secondary exposure to anticoagulant rodenticides in European polecats Mustela putorius in Great Britain
As a result of legal protection and population recovery, European polecats (Mustela putorius) in Great Britain are expanding into areas associated with greater usage of second-generation anticoagulant rodenticides (SGARs). We analysed polecat livers collected from road casualties from 2013 to 2016 for residues of five SGARs.

Mapping the spatial configuration of hybridization risk for an endangered population of the European wildcat (Felis silvestris silvestris) in Scotland
The wildcat in Scotland, UK, is currently at risk of extinction because of hybridization with feral domestic cats (ferals) and hybrids (wildcat × domestic cat crosses). Conservation efforts are hampered by limited information on the distribution of these three cat types and the spatial variation in hybridization risk. From January 2010 to...Kilshaw, Kerry ; Montgomery, Robert A ; Campbell, R D ; Hetherington, David A ; Johnson, Paul J …
