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

Water is a key resource for most large bodied mammals in the world’s arid areas. With the growing human population, access to water for wildlife often becomes compromised. Equids are typical inhabitants of semi-arid to arid rangelands and need regular access to fresh water. However, their water needs are difficult to study under free-ranging conditions. In this study we investigated Asiatic wild ass (Equus hemionus) use of permanent water points in the Great Gobi B Strictly Protected Area (SPA) in south-western Mongolia. We combined observational data from one specific water point with high frequency GPS location data from …
Temporal Dynamics Of Group Size And Sexual Segregation In Ibex, N. J. Singh, S. Amgalanbaatar, Richard P. Reading
Temporal Dynamics Of Group Size And Sexual Segregation In Ibex, N. J. Singh, S. Amgalanbaatar, Richard P. Reading

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 …
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
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

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 …
