Investigation Of Bats In The Darkhad Wetlands, Jargalsaikhan Ariunbold

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

The Darkhadyn Khotgor wetlands are located in the northern part of Mongolia and are transected by both small and large rivers such as the Shishged and the Tengis. Many small lakes are present and the large lake ‘Tsagaan nuur’ (English: White lake) is upstream of the Yenisei river. It is a land rich in biodiversity with pristine waters and an extreme continental climate. The Darkhadyn Khotgor wetlands are composed of three ecological zones, Siberian Taiga, forested steppe, and meadow valley. The area is surrounded by Ulaan Taiga strictly protected area (SPA) in the western part, Khoridol Saridag Mountains SPA in …

Morphology And Variation Of The Asiatic Wild Ass (Equus Hemionus Hemionus), Kati Schöpke, Annegret Stubbe, Michael Stubbe, Nyamsuren Batsaikhan, Renate Schafberg

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

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 …

Comparative Morphology Of Two Sympatric Species Of Hedgehog In Ikh Nart Nature Reserve, Mongolia, Richard P. Reading, David Kenny, Sodnomphil Batdorj, James Murdoch

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

Daurian hedgehog (Mesechinus dauuricus) and long-eared hedgehog (Hemiechinus auritus) inhabit Ikh Nart Nature Reserve, Mongolia and both species appear to occupy similar niches. We gathered morphological measurements to test for differences between species and sexes. We hoped to gain insight into the mechanisms that allow the species to coexist. We collected morphometric data from 10 long-eared hedgehogs (6 male, 4 female) and 18 Daurian hedgehogs (10 male, 7 female, and 1 unknown sex). Only total body length in Daurian hedgehogs differed significantly between males and females. Otherwise, we found no significant differences between morphometric measures of …

Beitrag Zur Säugetierfauna Des Staatlichen Naturschutzgebietes Azas In Tyva/Südsibirien = Contributions To Fauna And Ecology Of Small Mammals Of State Nature Reserve “Azas” In The Republic Of Tyva /South Siberia, Annegret Stubbe, Michael Stubbe, V. V. Unžakov, A. P. Saveljev, N. I. Putincev, W. Stubbe

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

During 1988-2004 Russian and German biologists carried out a research of biodiversity of the mountain taiga within the territory of State Nature Reserve “Azas” (Republic of Tyva/Russia). Along with executing the main task – studying and development of an aboriginal population of Tuvinian beavers Castor fiber tuvinicus – materials on the fauna of small mammals of the Todzha kettle were collected. On the basis of samples (about 550 collected micromammals) information on the occurrence, reproduction and morphometric characteristics of four species of Insectivora, six species of Chiroptera and eleven species of small Rodentia inhabiting the territory of the reserve “Azas” …

Contributions To The Chiroptera Of Mongolia With First Evidences On Species Communities And Ecological Niches, Dietrich Dolch, Nyamsuren Batsaikhan, Klaus Thiele, Frank Burger, Ingo Scheffler, Andreas Kiefer, Frieder Mayer, Ravčigijn Samjaa, Annegret Stubbe, Michael Stubbe, Leonard Krall, Dirk Steinhauser

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

In this paper are presented the accounts of 13 identified bat species from a total of 628 captured specimens from 32 locations in Mongolia during three field expeditions. These species accounts include taxonomical, morphological, and ecological data resulting from observations and further analyses. As a result of this work the distribution of some bat species in Mongolia can be drawn in more detail. For instance, Vespertilio murinus is much wider distributed and abundant than the former records indicate. The Plecotus species were clearly identified by genetic analyses combined with morphological characteristics. Moreover, the second record for Eptesicus serotinus and the …
