Stable isotope ecology and interspecific dietary overlap among dolphins in the Northeast Atlantic
Dolphins are mobile apex marine predators. Over the past three decades, warm-water adapted dolphin species (short-beaked common and striped) have expanded their ranges northward and become increasingly abundant in British waters. Meanwhile, cold-water adapted dolphins (white-beaked and Atlantic white-sided) abundance trends are decreasing, with evidence of the distribution of white-beaked...Plint, Tessa ; ten Doeschate, Mariel T I ; Brownlow, Andrew C ; Davison, Nicholas J ; Hantke, Georg …

The prevalence of vestigial teeth in two beaked whale species from the North Atlantic
Beaked whales, Family Ziphiidae, occur in deep offshore and oceanic seas, where they are very difficult to study, so that much of our knowledge about them is derived from stranded animals. Most beaked whales (e.g., genera and ) have only one pair of mandibular teeth. A reduced dentition is widely...Kitchener, Andrew C ; Herman, Jeremy S ; Doeschate, Mariel ten ; Davison, Nicholas J ; Brownlow, Andrew …

First recorded stranding of a short-finned pilot whale, Globicephala macrorhynchus, in Britain
A male pilot whale, Globicephala sp., was reported as a live stranding on 1st March 2012 at Hazelbeach, near Neyland, Pembrokeshire. It was euthanased and its skull was recovered during an onsite necropsy. Examination of the skull and contemporary photographs of the stranded animal confirm that this is the first...Kitchener, Andrew C ; Hantke, Georg ; Penrose, R S ; Perkins, M W ; Deaville, R

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

Intraspecific macroscopic digestive anatomy of ring-tailed lemurs (Lemur catta), including a comparison of frozen and formalin-stored specimens
Digestive tract measurements are often considered species specific, but little information exists on the degree to which they change during ontogeny within a species. Additionally, access to anatomical material from nondomestic species is often limited, with fixed tissues possibly representing the only available source, though the degree to which this...Clauss, Marcus ; Trümpler, Jelscha ; Ackermans, Nicole L ; Kitchener, Andrew C ; Hantke, Georg …

Investigating infectious disease threats to the recovery of the European polecat in Britain
The European polecat (Mustela putorius) almost became extinct in Britain in the early twentieth century, but populations are now recovering. As seen in other endangered carnivore populations, disease is one potential threat to recovery. This study assessed exposure of wild polecats (n = 149) to three, multi-host pathogens which could limit reproduction...Heald, Kari-Anne ; Millins, Caroline ; Kitchener, Andrew C ; Banyard, Ashley C ; Hantke, Georg …

Rapid evolution of the primate larynx?
Tissue vibrations in the larynx produce most sounds that comprise vocal communication in mammals. Larynx morphology is thus predicted to be a key target for selection, particularly in species with highly developed vocal communication systems. Here, we present a novel database of digitally modeled scanned larynges from 55 different mammalian...Bowling, Daniel L ; Dunn , Jacob C ; Smaers, Jeroen B ; Garcia, Maxime ; Sato , Asha …

How to sex Giant otter Pteronura brasiliensis (Gmelin, 1788) cubs
Sexing living neonate mammals may be difficult as external genitalia may be poorly developed and time may be limited for a detailed examination. Four neonate cubs of the Giant otter Pteronura brasiliensis were examined in order to determine a method to distinguish between the sexes. The distance between anal and...Hantke, Georg ; Kitchener, Andrew C

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. We related variation in...Sainsbury, Katherine A ; Shore, Richard F ; Schofield, Henry ; Croose, Elizabeth ; Pereria, M Gloria …
