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

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 …

A system for designating taxonomic certainty in mammals and other taxa
Taxonomy and systematics are fundamental to the success of conservation actions. A robust and accurate classification of living organisms is vital for understanding biodiversity, using limited resources wisely, prioritising conservation action, and for legal protection and regulation of trade. However, all too often current taxonomies are not based on the...Kitchener, Andrew C ; Hoffmann, Michael ; Yamaguchi, Nobuyuki ; Breitenmoser-Würsten, Christine ; Wilting, Andreas

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

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 …

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 …

On the edge: COP 15 and disappearing species
With COP 15 taking place in China this month, Principal Curator of Vertebrates Andrew Kitchener explores the case of the ivory-billed woodpecker. Thought to be extinct, but with potential sightings still reported, this bird is just one of many species we’re at risk of losing forever.Kitchener, Andrew C

Dedicated collector: Michael Daniels and his Eocene birds
A stunning collection of over 700 bird fossils has been bequeathed to National Museums Scotland. Collected in Essex by Michael Daniels, the fossils date from 54-56 million years ago, the beginning of the Eocene period. They represent the early stages in the evolution of modern birds and contain many species...Kitchener, Andrew C

Biogeography in the deep: Hierarchical population genomic structure of two beaked whale species
The deep sea is the largest ecosystem on Earth, yet little is known about the processes driving patterns of genetic diversity in its inhabitants. Here, we investigated the macro- and microevolutionary processes shaping genomic population structure and diversity in two poorly understood, globally distributed, deep-sea predators: Cuvier’s beaked whale (Ziphius... -

Phenotypic plasticity determines differences between the skulls of tigers from mainland Asia
Tiger subspecific taxonomy is controversial because of morphological and genetic variation found between now fragmented populations, yet the extent to which phenotypic plasticity or genetic variation affects phenotypes of putative tiger subspecies has not been explicitly addressed. In order to assess the role of phenotypic plasticity in determining skull variation,...
