  • Molecular and Functional Evolution of Hemoglobin in Perissodactyl
    Molecular and functional evolution of hemoglobin in perissodactyl mammals (equids, tapirs, and rhinos) by Margaret Clapin A thesis submitted to the Faculty of Graduate Studies of the University of Manitoba in partial fulfillment of the requirements for the degree of Master of Science Department of Biological Sciences University of Manitoba Winnipeg, Manitoba Canada © 2019 Abstract: In this thesis, the oxygen binding characteristics of recombinant hemoglobin (Hb) isoforms (HbA [α2β2] and HbA2 [α2δ2]) from the extinct woolly rhinoceros (Coelodonta antiquitatis) are compared with Sumatran rhino (Dicerorhinus sumatrensis) and black rhino (Diceros bicornis) Hb. The major Hb component (HbA) of horses (Equus caballus) was also examined, as its blood O2 affinity has a low thermal sensitivity. This trait is commonly associated with cold-adaptation as it permits O2 to be offloaded at the cool peripheral tissues of regionally endothermic mammals, though the mechanism(s) by which the oxygenation enthalpy is reduced in horse Hb is unknown. It was hypothesized that the woolly rhino Hb isoforms would have similarly low thermal sensitivities to that of horses, either through enhanced effector binding or by altering the energetic transition from the tense to the relaxed state of hemoglobin. To test this hypothesis the hemoglobin coding sequences for each of the above species were determined and their Hb isoforms expressed using E. coli and purified. Oxygen equilibrium curves were then determined in the presence and absence of allosteric effectors at 25 and 37°C. Horse HbA had a low sensitivity to 2,3- diphosphoglycerate (DPG), though its low temperature sensitivity was primarily driven by increased DPG binding at the lower test temperature.

  • Evolution and Extinction of the Giant Rhinoceros Elasmotherium Sibiricum Sheds Light on Late Quaternary Megafaunal Extinctions
    ARTICLES https://doi.org/10.1038/s41559-018-0722-0 Evolution and extinction of the giant rhinoceros Elasmotherium sibiricum sheds light on late Quaternary megafaunal extinctions Pavel Kosintsev1, Kieren J. Mitchell2, Thibaut Devièse3, Johannes van der Plicht4,5, Margot Kuitems4,5, Ekaterina Petrova6, Alexei Tikhonov6, Thomas Higham3, Daniel Comeskey3, Chris Turney7,8, Alan Cooper 2, Thijs van Kolfschoten5, Anthony J. Stuart9 and Adrian M. Lister 10* Understanding extinction events requires an unbiased record of the chronology and ecology of victims and survivors. The rhi- noceros Elasmotherium sibiricum, known as the ‘Siberian unicorn’, was believed to have gone extinct around 200,000 years ago—well before the late Quaternary megafaunal extinction event. However, no absolute dating, genetic analysis or quantita- tive ecological assessment of this species has been undertaken. Here, we show, by accelerator mass spectrometry radiocarbon dating of 23 individuals, including cross-validation by compound-specific analysis, that E. sibiricum survived in Eastern Europe and Central Asia until at least 39,000 years ago, corroborating a wave of megafaunal turnover before the Last Glacial Maximum in Eurasia, in addition to the better-known late-glacial event. Stable isotope data indicate a dry steppe niche for E. sibiricum and, together with morphology, a highly specialized diet that probably contributed to its extinction. We further demonstrate, with DNA sequencing data, a very deep phylogenetic split between the subfamilies Elasmotheriinae and Rhinocerotinae that includes all the living rhinoceroses, settling a debate based on fossil evidence and confirming that the two lineages had diverged by the Eocene. As the last surviving member of the Elasmotheriinae, the demise of the ‘Siberian unicorn’ marked the extinction of this subfamily.

  • Ancient Metaproteomics: a Novel Approach for Understanding Disease And
    Ancient metaproteomics: a novel approach for understanding disease and diet in the archaeological record Jessica Hendy PhD University of York Archaeology August, 2015 ii Abstract Proteomics is increasingly being applied to archaeological samples following technological developments in mass spectrometry. This thesis explores how these developments may contribute to the characterisation of disease and diet in the archaeological record. This thesis has a three-fold aim; a) to evaluate the potential of shotgun proteomics as a method for characterising ancient disease, b) to develop the metaproteomic analysis of dental calculus as a tool for understanding both ancient oral health and patterns of individual food consumption and c) to apply these methodological developments to understanding individual lifeways of people enslaved during the 19th century transatlantic slave trade. This thesis demonstrates that ancient metaproteomics can be a powerful tool for identifying microorganisms in the archaeological record, characterising the functional profile of ancient proteomes and accessing individual patterns of food consumption with high taxonomic specificity. In particular, analysis of dental calculus may be an extremely valuable tool for understanding the aetiology of past oral diseases. Results of this study highlight the value of revisiting previous studies with more recent methodological approaches and demonstrate that biomolecular preservation can have a significant impact on the effectiveness of ancient proteins as an archaeological tool for this characterisation. Using the approaches developed in this study we have the opportunity to increase the visibility of past diseases and their aetiology, as well as develop a richer understanding of individual lifeways through the production of molecular life histories. iii iv List of Contents Abstract ...............................................................................................................................

A review of studies of sexual dimorphism in the vertebrate fossil record revealed methods that were selected for use in ceratopsids. Mountain goats, bison, and pronghorn were selected as exemplar taxa for a proof of principle study that tested the selected methods, and informed and guided the investigation of sexual dimorphism in dinosaurs. Skulls of these exemplar taxa were measured in museum collections, and methods of analysing morphological variation were tested for their ability to demonstrate sexual dimorphism in their horns and horncores.
