A collection of recent skeletal remains from the Asiatic wild ass (Equus hemionus hemionus PALLAS) was prepared and stored in the Museum of Domesticated Animals “JULIUS KÜHN” in Halle, Germany.

The collection is based on carcass remains sampled between 2001 and 2006 under the leadership of Michael Stubbe during joint Mongolian-German Biological Expeditions

Skeletal remains of 43 individual specimens were studied (18 mares, 15 stallions, and 10 juvenile asses). The determination of sex and age was initially based on carcass information from observations made in situ in the field. Subsequently, skull traits, including dentition and development of canine teeth …

Long-Term Ecology Of Asiatic Wild Ass (Equus H. Hemionus Pallas) In Central Asia, Annegret Stubbe, Michael Stubbe, Nyamsuren Batsaikhan, Ravčigijn Samjaa

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The main population of the nominate form Equus hemionus hemionus Pallas, 1775 occurs in the south-east Gobi desert of Mongolia. From 2003 to 2012 we studied the reproductive ecology and mortality of dschiggetajs or khulans (English also ‘hulan’). During these years, the rate of reproduction was variable, ranging from 6.4% to 23.0% depending on climate, feeding conditions, and fitness of the mares. Our research shows that there appears to be a relationship between minimum temperatures in June (main foaling time) and rate of successful reproduction. The primary cause of decline in the numerical density of the population of E. hemionus …

Quo Vadis Equus Hemionus Hemionus In Mongolia?, Annegret Stubbe, Michael Stubbe, O. Shagdarsuren, Ravčigijn Samjaa, Nayamsuren Batsaikhan

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Caused in studies on biodiversity in the South Gobi we were confronted with the human impact on animal communities and endangered animal species, especially the Asiatic wild ass. So was born the idea to organize an international conference with the aim to actualize the status of Equus hemionus in Central Asia and to find ways for better conservation of this species and its habitats. A short review is given on historical exploration, decreasing area and population number of the Dschiggetai. Today the range of the nominate form of Equus hemionus is located in the Gobi region of southern Mongolia/northern China …

Remarks On The Social System Of The Mongolian Wild Ass (Equus Hemionus Hemionus), Gertrud Neumann-Denzau, Helmut Denzau

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

So far the social system of Mongolian wild asses is non-uniformly interpreted. The authors describe their own observations from different parts of Mongolia and review data from available publications. The arguments support a territorial social system, which agrees with the social system of all other wild asses in Asia and Africa.

First Results Of Wild Ass Research In The South Gobi Aymag/Mongolia In 2003 And 2004, Annegret Stubbe, Michael Stubbe, N. Batsajchan, R. Samjaa, S. Doržderem

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The population of the Mongolian wild ass belongs to the nominate form Equus hemionus hemionus described by Pallas in 1775. This species is adapted to semidesert habitats in the Gobi region and is listed in the Red Book of Mongolia as well as on appendix I of the Washington Convention (CITES). Mapping of the northern border of the distributional range showed a remarkable decrease in size in comparison to the maps of Murzaev (1954) or Bannikov (1954). The pressure of civilization, settlements, motorization, and increasing numbers of domestic livestock in connection with the occupation of water resources and illegal hunting …
