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. -
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 ............................................................................................................................... -

Pleistocene Panthera Leo Spelaea
Quaternaire, 22, (2), 2011, p. 105-127 PLEISTOCENE PANTHERA LEO SPELAEA (GOLDFUSS 1810) REMAINS FROM THE BALVE CAVE (NW GERMANY) – A CAVE BEAR, HYENA DEN AND MIDDLE PALAEOLITHIC HUMAN CAVE – AND REVIEW OF THE SAUERLAND KARST LION CAVE SITES n Cajus G. DIEDRICH 1 ABSTRACT Pleistocene remains of Panthera leo spelaea (Goldfuss 1810) from Balve Cave (Sauerland Karst, NW-Germany), one of the most famous Middle Palaeolithic Neandertalian cave sites in Europe, and also a hyena and cave bear den, belong to the most im- portant felid sites of the Sauerland Karst. The stratigraphy, macrofaunal assemblages and Palaeolithic stone artefacts range from the final Saalian (late Middle Pleistocene, Acheulean) over the Middle Palaeolithic (Micoquian/Mousterian), and to the final Palaeolithic (Magdalénien) of the Weichselian (Upper Pleistocene). Most lion bones from Balve Cave can be identified as early to middle Upper Pleistocene in age. From this cave, a relatively large amount of hyena remains, and many chewed, and punctured herbivorous and carnivorous bones, especially those of woolly rhinoceros, indicate periodic den use of Crocuta crocuta spelaea. In addition to those of the Balve Cave, nearly all lion remains in the Sauerland Karst caves were found in hyena den bone assemblages, except those described here material from the Keppler Cave cave bear den. Late Pleistocene spotted hyenas imported most probably Panthera leo spelaea body parts, or scavenged on lion carcasses in caves, a suggestion which is supported by comparisons with other cave sites in the Sauerland Karst. The complex taphonomic situation of lion remains in hyena den bone assemblages and cave bear dens seem to have resulted from antagonistic hyena-lion conflicts and cave bear hunting by lions in caves, in which all cases lions may sometimes have been killed and finally consumed by hyenas. -
Late Pleistocene Panthera Leo Spelaea (Goldfuss, 1810) Skeletons
Late Pleistocene Panthera leo spelaea (Goldfuss, 1810) skeletons from the Czech Republic (central Europe); their pathological cranial features and injuries resulting from intraspecific fights, conflicts with hyenas, and attacks on cave bears CAJUS G. DIEDRICH The world’s first mounted “skeletons” of the Late Pleistocene Panthera leo spelaea (Goldfuss, 1810) from the Sloup Cave hyena and cave bear den in the Moravian Karst (Czech Republic, central Europe) are compilations that have used bones from several different individuals. These skeletons are described and compared with the most complete known skeleton in Europe from a single individual, a lioness skeleton from the hyena den site at the Srbsko Chlum-Komín Cave in the Bohemian Karst (Czech Republic). Pathological features such as rib fractures and brain-case damage in these specimens, and also in other skulls from the Zoolithen Cave (Germany) that were used for comparison, are indicative of intraspecific fights, fights with Ice Age spotted hyenas, and possibly also of fights with cave bears. In contrast, other skulls from the Perick and Zoolithen caves in Germany and the Urșilor Cave in Romania exhibit post mortem damage in the form of bites and fractures probably caused either by hyena scavenging or by lion cannibalism. In the Srbsko Chlum-Komín Cave a young and brain-damaged lioness appears to have died (or possibly been killed by hyenas) within the hyena prey-storage den. In the cave bear dominated bone-rich Sloup and Zoolithen caves of central Europe it appears that lions may have actively hunted cave bears, mainly during their hibernation. Bears may have occasionally injured or even killed predating lions, but in contrast to hyenas, the bears were herbivorous and so did not feed on the lion car- casses. -

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. -

Introduction Mammals are currently among the main victims of human depredations on the environment. A huge amount of species and subspecies have disappeared to date, revealing human exploitation of natural resources as a long lasting process beginning in prehistorical periods and lasting until historical times. In the late Pleistocene, for example, the modern mammalian fauna assemblages of the Western Palaearctic Region were already defined. They would have yet comprised the totality of the species still surviving today, if some extinctions had not mainly affected large terrestrial mammals between 15.000UNESCO and 10.000 years BP, such –as the EOLSS mammoth (Mammuthus primigenius Blumenbach, 1803), the cave bear (Ursus spelaeus Rosenmuller & Heinroth, 1794), the woolly rhinoceros (Coelodonta antiquitatis Blumenbach, 1803), the giant deer (Megaloceros giganteus Berckhemer, 1910), and others. All these extinctions were without replacementSAMPLE by ecologically similar species:CHAPTERS for large mammals - i.e. species exceeding about 40 kg mean adult body weight - it has been estimated that Europe lost approximately 7 out of 24 genera (i.e. -
Frequency of Pathology in a Large Natural Sample from Natural Trap

L’evidenza di artrite erosiva è confinata ai bovidi, Bison, Ovis e Bootherium, fatto osservabile anche in bisonti del tardo Pleistocene ritrovati nel Kansas (Twelve Mile Creek) e in un’altra località del Wisconsin, riferibile cronologi- camente al primo Olocene. Questi dati, ovvero la restrizione di tali segni di patologia articolare ad un singolo gene- re animale (Bovidi) e ad un determinato periodo storico, rende plausibile l’ipotesi che un agente patogeno, identifi- cabile col Mycobacterium tubercolosis, possa essere stato implicato nella genesi dell’artrite erosiva. Osteoartrosi e DISH sono risultate poco rappresentate nella popolazione animale della Natural Trap Cave, anche se il genere Bi- son ha dimostrato una discreta prevalenza di segni di osteoartrosi. -
Pleistocene Cave Hyenas in the Iberian Peninsula: New Insights from Los Aprendices Cave (Moncayo, Zaragoza)
Palaeontologia Electronica palaeo-electronica.org Pleistocene cave hyenas in the Iberian Peninsula: New insights from Los Aprendices cave (Moncayo, Zaragoza) Víctor Sauqué, Raquel Rabal-Garcés, Joan Madurell-Malaperia, Mario Gisbert, Samuel Zamora, Trinidad de Torres, José Eugenio Ortiz, and Gloria Cuenca-Bescós ABSTRACT A new Pleistocene paleontological site, Los Aprendices, located in the northwest- ern part of the Iberian Peninsula in the area of the Moncayo (Zaragoza) is presented. The layer with fossil remains has been dated by amino acid racemization to 143.8 ± 38.9 ka (earliest Late Pleistocene or latest Middle Pleistocene). Five mammal species have been identified in the assemblage: Crocuta spelaea (Goldfuss, 1823) Capra pyre- naica (Schinz, 1838), Lagomorpha indet, Arvicolidae indet and Galemys pyrenaicus (Geoffroy, 1811). The remains of C. spelaea represent a mostly complete skeleton in anatomical semi-connection. The hyena specimen represents the most complete skel- eton ever recovered in Iberia and one of the most complete remains in Europe. It has been compared anatomically and biometrically with both European cave hyenas and extant spotted hyenas. In addition, a taphonomic study has been carried out in order to understand the origin and preservation of these exceptional remains. The results sug- gest rapid burial with few scavenging modifications putatively produced by a medium sized carnivore. A review of the Pleistocene Iberian record of Crocuta spp. has been carried out, enabling us to establish one of the earliest records of C. spelaea in the recently discovered Los Aprendices cave, and also showing that the most extensive geographical distribution of this species occurred during the Late Pleistocene (MIS4- 2). -
