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

The „Baikalgrabenzone“ or Tunka valley is the area between the lake Chubsugul in the Southwest and the bassin of the river Oljekma in the Northeast. It’s an important biogeograhic region. Some bird species are immigrating from Mongolia in this area, some other species are disapeared here. In the ornithofauna can be distinguished ten types of zoogeographic origin.

The Institute For Raptor Studies Expeditions In Mongolia, 1994-2000, David H. Ellis

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

In 1994, 1995, 1997, 1998, and 2000, I led small teams of biologists across Mongolia in search of Saker falcon (Falco cherrug Gray) and golden eagle (Aquila chrysaetos) eyries. We also counted raptors along our march route during the first three years. These expeditions documented: (1) occupancy and productivity rates, and described eyrie sites, for Saker falcons (150 territories, 182 eyries) and golden eagles (27 known breeding territories), (2) mortality of Sakers and ipland buzzards (Buteo hemilasius) due to entanglement with trash in nests and loss of golden eagle eggs due to concealment by trash in nests, …

Paleo-Environmental Changes In The Uvs Nuur Basin (Northwest-Mongolia), Michael Walther

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

Geomorphological, geochemical, sedimentological and palynological results are presented against the background of palaeoclimatic changes during the past 15,000 years, yielding a chrono-, bio- and morphostratigraphical model of landscape evolution in the region of northern Central Asia. Holocene and Late-Glacial climatic fluctuations there are shown to correlate well with conditions in central Europe. Particular attention is given to the importance of the palaeoclimatic interpretation of lake Basin sediments when reconstructing the palaeoenvironment.

The Use Of High Frequency Gps Data To Classify Main Behavioural Categories In A Przewalski’S Horse In The Mongolian Gobi, Petra Kaczensky, Klaus Huber

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

Behavioral observations of free ranging animals can provide important insight into many aspects of their biology but are not without problems. The recent development of GPS technology allows to remotely collect high precision location data at fixed intervals. We tested whether it is possible to classify the behavior of a Przewalski’s horse in the Mongolian Gobi into Resting, Grazing and Moving based on GPS locations collected at 15 minute intervals by comparing GPS data with direct observations. Although behavioral categories lasting for 15 minutes could by fairly reliably separated based on the distances covered between successive fixes, almost half the …

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 …

Characteristics Of Mongolian Wild Ass Hooves (Equus Hemionus Hemionus), Jan Gahsche, Michael Stubbe, Matthias Oppermann, N. Batsajchan, Annegret Stubbe

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

Measurements of hoof angles, hoof length, toe length, etc., and non-metrical hoof characters of Mongolian Wild Ass carcasses collected in in the South Gobi and in Bordzongijn-Gobi desert are presented. Khulan hooves are flat, wide and look big in relation to the animal’s dimensions. Remarkably is the wide variability in size, angles, in non metric characteristics like shape, color and the occurrence of particularly prolonged hoof wall and flaring walls. For example, toe angles are 52° for front and 54° for hind hooves on average. This measures and the suggested graphical model of the „ideal hoof shape“ can assist to …

Temporal Dynamics Of Group Size And Sexual Segregation In Ibex, N. J. Singh, S. Amgalanbaatar, Richard P. Reading

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

Group size is an important variable describing behavioral ecology of animals. A variety of factors such as habitat characteristics, life history, spatio-temporal resource dynamics, population density, predation risk, competition with kin, and social learning often determine group size in large mammals. We studied temporal dynamics of group size in Siberian ibex (Capra sibirica) in a protected area in Mongolia. We measured monthly and yearly variations in typical group size and used the sexual segregation and aggregation statistic to assess sexual segregation. Ibex formed the largest groups in November and smallest groups in July. However, group sizes did not …

Ecology Of Eurasian Black Vultures (Aegypius Monachus) In Ikh Nart Nature Reserve, Mongolia, Richard P. Reading, David Kenny, John Azua, Travis Garrett, Mary Jo Willis, Tsolmonjav Purevsuren

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

We studied the nesting ecology and movement patterns of Eurasian black vultures (Aegypius monachus) nesting in and near Ikh Nart Nature Reserve, Dornogobi Aimag, Mongolia. From 2003 till 2009, we monitored nesting pairs from incubation to fledging and compared nesting success for pairs nesting on rocks and trees. We captured chicks just prior to fledging to apply leg bands and wing tags. We also captured adults in June and attached solar-powered global positioning system (GPS)/satellite telemetry units, leg bands, and wing tags. We collected resighting data on marked birds opportunistically and telemetry data on tagged birds. We monitored …

A Contribution To The Bats Inhabiting Arid Steppe Habitats In Central Mongolia, Nyambayar Batbayar, Ariunbold Jargalsaikhan, Sukhchuluun Gansukh

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

Bats of the steppe habitat require particular attention in Mongolia because of increasingly frequent droughts and the looming specter of global warming which could have a devastating impact on their population. Especially the bats in arid steppe region lack of water resources. All bat species we trapped in Erdenesant, Tov aimag, were using hand dug wells as water source indicating the significance of water availability. Many wells have been dried out or polluted in Mongolia in recent years due to warming effect of climate change and artisanal mining activities, but the extent of their impacts on bat populations have to …

This work summarizes the longtime ecological research of the German-Mongolian scientific cooperation regarding biodiversity studies in Central Asia, focusing on native raptor species (Aves: Falconiformes). There is included a short overview on the history of raptor research in Mongolia. One of the primary goals was the creation of distribution maps of breeding records based on definitive time and space coordinates. Additional data on the breeding biology amend the distribution data. Currently 43 raptor species are recorded for Mongolia. Whenever possible were also incorporated data from adjacent regions of Mongolia (China, Tuva, Burjatia, Pribaikalia), in order to embed the avifauna of …

Estimates Of Toad Headed Agama Density In Three Steppe Habitats Of Mongolia, James Murdoch, Buyandelger Suuri, Richard P. Reading

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

The toad headed agama (Phrynocephalus versicolor) ranges across the arid steppe regions of southern and western Mongolia and represents one of the most common reptiles in the country. However, few details of the species’ population characteristics exist, which may be important for evaluating population trends and assessing its conservation status. We estimated toad headed agama density in Ikh Nart Nature Reserve, Mongolia based on surveys conducted in the summers (June-September) of 2005, 2006, 2008, and 2009. We conducted surveys in three steppe habitats including tall grassland (n = 7), shrub-steppe (n = 7), and semi-shrub steppe …
