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. -

ABSTRACT: Tissue samples from an alleged Mexican Onza, shot in the western Sierra Madre in 1986, were subjected to several biochemical assays in an attempt to determine the specimen's relationship to felid species of North America. Protein analyses included isoenzyme electrophoresis and albumin isoelectric focusing. Mi- tochondrial DNA was assayed for restriction fragment lengths with 28 restriction enzymes, and the NÐ5 gene was sequenced. The resulting protein and rnitochondrial DNA characteristics of the Onza were indistinguishable from those of North Amer- ican pumas. INTRODUCTION In the Americas, there are two documented species of large cats: 1) Puma concolor, the puma, also called mountain lion, cougar, and panther in dif- ferent regions of North America, and known as leon in Mexico; and 2) Panthera onca, the jaguar, or tigre as it is known south of the U.S. border.

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

Mammalia: Carnivora) in the Americas: Past to Present
Journal of Mammalian Evolution https://doi.org/10.1007/s10914-020-09496-8 ORIGINAL PAPER Environmental Drivers and Distribution Patterns of Carnivoran Assemblages (Mammalia: Carnivora) in the Americas: Past to Present Andrés Arias-Alzate1,2 & José F. González-Maya3 & Joaquín Arroyo-Cabrales4 & Rodrigo A. Medellín5 & Enrique Martínez-Meyer2 # Springer Science+Business Media, LLC, part of Springer Nature 2020 Abstract Understanding species distributions and the variation of assemblage structure in time and space are fundamental goals of biogeography and ecology. Here, we use an ecological niche modeling and macroecological approach in order to assess whether constraints patterns in carnivoran richness and composition structures in replicated assemblages through time and space should reflect environmental filtering through ecological niche constraints from the Last Inter-glacial (LIG), Last Glacial Maximum (LGM) to the present (C) time. Our results suggest a diverse distribution of carnivoran co-occurrence patterns at the continental scale as a result of spatial climatic variation as an important driver constrained by the ecological niches of the species. This influence was an important factor restructuring assemblages (more directly on richness than composition patterns) not only at the continental level, but also from regional and local scales and this influence was geographically different throughout the space in the continent. These climatic restrictions and disruption of the niche during the environmental changes at the LIG-LGM-C transition show a considerable shift in assemblage richness and composition across the Americas, which suggests an environ- mental filtering mainly during the LGM, explaining between 30 and 75% of these variations through space and time, with more accentuated changes in North than South America. -
