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 ............................................................................................................................... -
The Ancients' One-Horned
The Ancients’ One-Horned Ass: Accuracy and Consistency Chris Lavers HIS PAPER explores ancient Greek and Roman accounts of the one-horned ass.1 These narratives have been studied extensively by literary scholars and historians but have Tbeen largely ignored by zoologists and geographers. When the zoological and geographical underpinnings of the accounts are examined, however, it becomes apparent that these ancient writers may have had a more definite notion of the region about which they wrote than hitherto has been assumed. The animals contributing to the descriptions of the one-horned ass by Ctesias, Pliny, and Aelian can be found in the highlands of Central Asia. Indeed, Central Asia appears to be the only place on the Earth’s surface that could have given rise to the corpus of ancient accounts of the unicorned ass and the animals that shared its landscape. 1. Introduction Ctesias of Cnidus was a Greek physician who spent seventeen years ministering at the court of the King of Persia. In 398 B.C. he returned to Greece and began two reference works, a history of Persia in twenty-three volumes, now mostly lost, and Indica, a treatise on the region probably roughly coincident with 1 It will quickly become apparent to regular readers of this journal that the author is not a classicist. I am greatly indebted to Kent Rigsby, the editorial board of GRBS, and an anonymous reviewer for considering a manuscript from a zoologist, and for their kind assistance in turning a clumsy initial submission into the present, less clumsy version. All opinions and errors are mine. -

The Importance of Wallows to Javan Rhino Ecology and Behaviour
RESEARCH More than just mud: the importance of wallows to Javan rhino ecology and behaviour Steven G Wilson1,2*,Georgina Hockings1, Jo-Anne M Deretic2, Salit Kark1 1The Biodiversity Research Group, The School of Biological Sciences, Centre for Biodiversity and Conservation Science, The University of Queensland, Brisbane, QLD, 4072 Australia 2Land, Biodiversity and Indigenous and River Health Programs, Goulburn Broken Catchment Management Authority, 168 Welsford Street, Shepparton, VIC 3632 Australia *corresponding author: [email protected] Abstract All members of the family Rhinocerotidae have the need to wallow in mud or water to protect their skin from sun damage, remove ectoparasites and for thermoregulation purposes. Just 72 wild Javan rhino (Rhinoceros sondaicus) remain on the planet, all located in their last stronghold in Ujung Kulon National Park (UKNP), West Java, Indonesia. Javan rhinos need to wallow regularly throughout the year, yet the role wallows play in their behaviour and the importance to the species remains little understood. In this study, we identified, mapped and studied 35 wallows in eastern UKNP, where rhinos were active. We spatially mapped and recorded each wallow’s characteristics. We examined rhino wallowing behaviour using 392 remote camera trap videos, taken across UKNP during a five-year study from 2011 to 2016. We identified and categorised eight behavioural patterns at and near wallows related to rhino daily activities and found that wallows have several key features for the Javan rhinos. Findings revealed that Javan rhinos, who construct the wallows themselves, choose sites with 75% shade cover and often at an elevation. Analysis of the rhino calls from camera trap videos taken at and near wallows, identify seven vocalisation descriptors with accompanying sonograms, a first for this rare and shy rainforest species. -
Sumatran Rhinoceros
Sumatran rhinoceros Name and species • Common name: Sumatran rhino • Synonyms: Asian two-horned rhino or the Hairy rhino • Scientific name: Dicerorhinus sumatrensis, from the Greek “di”, meaning "two", “cero”, meaning "horn" and “rhinos”, meaning "nose"; “sumatrensis”, from Sumatra Physical characteristics • Sumatran rhinos have a reddish-brown skin, in the wild variably covered with short bristly hair. In captivity the hair can grow out to a shaggy fur, because of less abrasion from vegetation. The ears edges have a prominent fringe of longer hairs, and the tail is terminate with a tuft of thicker hairs. There are two prominent folds in the skin circling the body behind the front legs and before the hind legs, and lesser folds on the neck and at the basis of the legs. The skin is rather thin, about 10-16 mm, and soft and pliable. Subcutaneous fat is absent in wild animals, but may occur in zoo specimens • The Sumatran rhino is considered the most “primitive” rhino species, because of its hairy skin and other ancient characteristics. It is the closest relative alive of the famous woolly rhinoceros that lived in the frigid lands of Europe and Asia during the past ice-ages • Sumatran rhinos are by far the smallest of the five living species of rhino. They weigh between 500-800 kilos, often more in captivity), stand 1.20-1.45 metres tall at the shoulder, and are about 2.50 metres long • The head is 70-80 cm in length and the tails vary in length from 35-60 cm • Sumatran rhinos have two horns, dark grey to black in colour. -

Waging a War to Save Biodiversity: the Rise of Militarized Conservation
Waging a war to save biodiversity: the rise of militarized conservation ROSALEEN DUFFY* Conserving biodiversity is a central environmental concern, and conservationists increasingly talk in terms of a ‘war’ to save species. International campaigns present a specific image: that parks agencies and conservation NGOs are engaged in a continual battle to protect wildlife from armies of highly organized criminal poach- ers who are financially motivated. The war to save biodiversity is presented as a legitimate war to save critically endangered species such as rhinos, tigers, gorillas and elephants. This is a significant shift in approach since the late 1990s, when community-based natural resource management (CBNRM) and participatory techniques were at their peak. Since the early 2000s there has been a re-evaluation of a renewed interest in fortress conservation models to protect wildlife, including by military means.1 Yet, as Lunstrum notes, there is a dearth of research on ‘green militarization’, a process by which military approaches and values are increasingly embedded in conservation practice.2 This article examines the dangers of a ‘war for biodiversity’: notably that it is used to justify highly repressive and coercive policies.3 Militarized forms of anti- poaching are increasingly justified by conservation NGOs keen to protect wildlife; these issues are even more important as conservationists turn to private military companies to guard and enforce protected areas. This article first examines concep- tual debates around the war for biodiversity; second, it offers an analysis of current trends in militarized forms of anti-poaching; third, it offers a critical reflection on such approaches via an examination of the historical, economic, social and political creation of poaching as a mode of illegal behaviour; and finally, it traces how a militarized approach to anti-poaching developed out of the production of poaching as a category. -
Detomidine and Butorphanol for Standing Sedation in a Range of Zoo-Kept Ungulate Species

E.C.Z.M., Joanne Dodds, V.N., Karla Berry, V.N., Abdi Arif, M.V.Sc., Polly Taylor, Vet. M. B., Ph. D., Dip. E.C.V.A.A., Andrew Routh, B. V. Sc., Cert. Zoo. Med., and Frank Gasthuys, D.V.M., Ph. D., Dip. E.C.V.A.A. Abstract: General anesthesia poses risks for larger zoo species, like cardiorespiratory depression, myopathy, and hyperthermia. In ruminants, ruminal bloat and regurgitation of rumen contents with potential aspiration pneumonia are added risks. Thus, the use of sedation to perform minor procedures is justified in zoo animals. A combination of detomidine and butorphanol has been routinely used in domestic animals. This drug combination, administered by remote intramuscular injection, can also be applied for standing sedation in a range of zoo animals, allowing a number of minor procedures. The combination was successfully administered in five species of nondomesticated equids (Przewalski horse [Equus ferus przewalskii; n ¼ 1], onager [Equus hemionus onager; n ¼ 4], kiang [Equus kiang; n ¼ 3], Grevy’s zebra [Equus grevyi; n ¼ 4], and Somali wild ass [Equus africanus somaliensis; n ¼ 7]), with a mean dose range of 0.10–0.17 mg/kg detomidine and 0.07–0.13 mg/kg butorphanol; the white (Ceratotherium simum simum; n ¼ 12) and greater one-horned rhinoceros (Rhinoceros unicornis; n ¼ 4), with a mean dose of 0.015 mg/kg of both detomidine and butorphanol; and Asiatic elephant bulls (Elephas maximus; n ¼ 2), with a mean dose of 0.018 mg/kg of both detomidine and butorphanol. -
Impact Report 2017–18 in This Era When the Fight Against Rhino Poaching Is Becoming More Modernised, We Tend to Neglect the Importance of the Human Element
Save the Rhino International Impact Report 2017–18 In this era when the fight against rhino poaching is becoming more modernised, we tend to neglect the importance of the human element. There is a critical need to look after our most important assets: our staff. All the technology in the world means nothing without the correct application of the boots on the ground, and that’s where the support of Save the Rhino and its donors has been so helpful. Eduard Goosen, Conservation Manager, uMkhuze Game Reserve, South Africa 2 OUR VISION A message from our CEO All five rhino species Save the Rhino started with adventure: motor-biking from thriving in the wild Nairobi to London for a ‘rhino scramble’ and climbing Mt Kilimanjaro to raise vital funds for OUR MISSION conservation programmes that were just beginning Collaborating with partners to to come out of an intense two decades of poaching. Since Save the Rhino was registered as a charity in support endangered rhinos in 1994, we have continued the adventure theme with Africa and Asia supporters taking on challenges of all shapes and sizes. All for one reason: to help rhinos. I’m proud to say that during the past year we have been able to give out our biggest sum of grants to date, totalling more than £2,000,000 OUR STRATEGIES and supporting 27 programmes across Africa and Asia. These funds have been used – among other things – to purchase boots, binoculars Saving rhinos and beds for rangers, as well as essential anti-poaching and 1 monitoring equipment so that wherever a rhino is, it can be protected.
