Differentiation of domestic Horse and Przewalskis Horse using various DNA sequences
Genetika, 1998Co-Authors: Glazko Vi, Zelenaia LbAbstract:The electrophoretic mobility of seven erythrocyte enzymes and spectra of fragments amplified by RAPD-PCR with primers UBC-85 and UBC-126 were comparatively analyzed in domestic Horse and Przewalski's Horse. All tested genetic markers were classified into two groups differing in their involvement in differentiation of the two closely related Horse species. Markers from different groups differed neither in their type (a polymorphic protein or an amplification product) nor in their biochemical role (for enzymes).

Przewalski’s Horse reintroduction in the State Natural Reserve «Orenburgsky»: the first results
Samara Journal of Science, 2019Co-Authors: Alexandr Nikolayevich TyurinAbstract:This paper presents a chronology of the main events taking place within the framework of the program to resettle Przhewalskys Horses to the territory inhabited by their close relatives, the tarpans, to create a new and sustainable population of these animals. The Przewalskis Horse population under natural conditions of the State Natural Reserve Orenburgsky will allow having a reserve of healthy, well-developed animals as a guarantee of keeping the species clean for a very long period of time. By the end of the 19th century, not a single Przewalskis wild Horse remained in its natural habitat. The paper discusses a gradual reintroduction of Przewalskis Horse and presents the first results, taken from open sources, on the restoration of the wild Horse population in the Orenburg Region. The first results allow you to look to the future with confidence. 5 healthy foals have already been born in the reserve; PA scientists are optimistic about the spring of 2019 and hope that the stock of wild Horses will continue to grow. The Przewalskis Horse reintroduction program enjoys a personal support of the Orenburg Region Governor and is among the key projects for the protection of wild animals, personally supervised by the President of the Russian Federation.

Space-time characterization of Przewalski's Horse movement in the Great Gobi B SPA in SW Mongolia
2016Co-Authors: Fohringer ChristianAbstract:Diese Studie verfolgt einen explorative Ansatz, um die Nutzungsverteilung von Przewalski-Pferden, unter besonderer Berücksichtigung von Zeitnutzungsparametern in der Great Gobi B SPA im SW der Mongolei, zu enthüllen. Drei Individuen aus drei verschiedenen sozialen Gruppen wurden im Juni 2013 mit einer neuen Generation von GPS-Iridium Halsbändern ausgestattet. Über einen Zeitraum von zwei Jahren wurden GPS-Positionen in stündlichen Intervallen erfasst. T-LoCoH (Time-Local Convex Hull), ein neues Verfahren zur empirische Kalkulation von Raumnutzungsverhalten, wurde ausgewählt um am besten Habitat- und Ressourcenauswahl besendeter Tiere unter Hinzuname einer zeitliche Dimension in Nächster-Nachbar „convex-hull“-Konstruktion, zu beschreiben. Dies ist die erste Anwendung dieses neuen Verfahrens an einer Spezies von derart großem Naturschutzinteresse. Genaue Definition und Differenzierung wertvoller Ressourcen wurde durch räumlich-zeitliche Überlappung Nahrungsaufnahme- und Trinkverhalten beeinträchtigt. Bedeutende direktionale Bewegungsmuster zwischen wertvollen Ressourcen und um anspruchsvolle topografische Züge konnten nachgewiesen werden. Verschiebungen der Raumnutzung konnten in einigen Fällen festgestellt werden; deren Bezug zu saisonalen Ressourcen war nicht ersichtlich. Oasen und Wasserstellen konnten als zentrale Komponenten im Nutzungsverhalten der Pferde nachgewiesen werden, indem sie auch die produktivsten bzw. am stärksten genutzten Vegetationsgemeinschaften enthalten. Die Nutzung von beschränktem Raum wurde mit hoher Präzision durch mehrere Werkzeuge des Algorithmus dargestellt. Mit Ausnahme der Tag-Nacht-Variation der durchschnittlichen Geschwindigkeit konnten keine 24-Stunden-Muster ermittelt werden. T-LoCoH erweist sich als wertvolles Tool um die räumlich-zeitlichen Bewegungsmuster von Przewalski-Pferden zu charakterisieren. Je nach Fragestellung arbeitet das Toolset dieses Algorithmus umso besser in Kombination mit anderen Metriken und Tools.Three Przewalskis Horses from three different social groups were equipped with a new generation of GPS-Iridium collars in June 2013 and have been collecting regular GPS locations at hourly intervals for almost two years allowing for a new analysis approach. This study pursues an explorative approach to elucidate Przewalskis Horses utilization distribution with special regard on time-use metrics in the Great Gobi B Special Protected Area of SW Mongolia. T-LoCoH (Time-Local Convex Hull), a novel method of empirical home range estimation was selected to best describe ranging behaviour, habitat selection and resource selection of collared animals by means of adding a temporal dimension to nearest-neighbour convex-hull construction. This is the first application of this novel method to a species of such a major conservation concern. Precise definitions and differentiation of important resources was hampered by spatiotemporal overlap of foraging and drinking behaviour. However, important directional movement (e.g. corridors) between valuable resources and around demanding topographical features could be detected. Range shifts could be visualized in some cases, but their relatedness to seasonal resource could not be confirmed. Oasis and water points were identified to be central regarding utilization distributions and their importance as habitat constituting most productive vegetation communities could be confirmed. Utilization of confined space-use was illustrated with high precision by multiple tools of the algorithm. Except for day-night variation regarding average speed, no 24-hour patterns could be detected from time-use metrics. T-LoCoH proofs to be a valuable implement to elucidate and characterize spatiotemporal movement of Przewalskis Horse in the Great Gobi B SPA. Depending on the research question, the toolset of this algorithm works all the better in combination with other metrics and home range estimating tools, rather than simply by itself.submitted by: Christian FohringerUniversität für Bodenkultur Wien, Masterarbeit, 2016(VLID)193577
