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 …

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 …

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, …

In deserts, native perennial plants often actually facilitate the establishment of exotic annual grasses. One of our focal areas of research is to identify native species for use in revegetation projects that reduce the establishment of exotic annual grasses, or at least do not strongly facilitate exotic species establishment. An initial research effort involving a competition experiment of red brome with native species and a correlational field study of brome distribution among native perennial plants is in press with the journal Invasive Plant Science and Management.

Desert fires fueled by exotic grasses like the omnipresent red brome (Bromus rubens) can be intense and cause widespread mortality of native vegetation. Native desert scrub communities such as those dominated by blackbrush (Coleogyne ramosissima) do not readily reestablish after fire (Abella 2009) and may even become more abundant in the post-burn landscape initiating a fire cycle that occurs at a greater frequency than the recovery time of the long-lived desert perennial community.
