A Lobed Argiope Spider On Its Most Eastern Distribution – First Record Of Argiope Lobata (Pallas, 1772) For The Sub-Family Argiopinae (Arachnida: Araneidae) In Mongolia, Oliver Lindecke, Marcus Wall Jan 2016

A Lobed Argiope Spider On Its Most Eastern Distribution – First Record Of Argiope Lobata (Pallas, 1772) For The Sub-Family Argiopinae (Arachnida: Araneidae) In Mongolia, Oliver Lindecke, Marcus Wall

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

The subfamily Argiopinae SIMON, 1890 is reported for Mongolia the first time by Argiope lobata (PALLAS, 1772). Furthermore, we herein highlight the most eastern distribution of this species, which is widespread in the Mediterranean, African and in some Asian countries. The obtained specimen was found in the Eastern Gobi, a landscape of semi-desert character. Despite numerous studies with arachnological background in the past, even larger species new for Mongolia could be found. Findings like this show the on-going need for basic biodiversity research in the Gobi ecoregions. We further discuss previous, but doubtful reports of A. lobata in South-east Asia …


Global Warming And Population Responses Among Great Plains Birds, Paul A. Johnsgard Feb 2015

Global Warming And Population Responses Among Great Plains Birds, Paul A. Johnsgard

Zea E-Books Collection

Based on an analysis of 47 years (1967–2014) of Audubon Christmas Bird Counts (CBC), evidence for population changes and shifts in early winter (late December) ranges of nearly 150 species of birds in the Great Plains states is summarized, a region defined as including the Dakotas, Nebraska, Kansas, Oklahoma, and the Texas panhandle. The rationale for this study had its origins in Terry Root’s 1988 Atlas of North American Wintering Birds. Root’s landmark study provided a baseline for evaluating the nationwide winter distributions of 253 North American birds in the mid-20th century, using data from the National Audubon Society’s …


Current Status Of The Khulan (Equus Hemionus) In The Trans-Altai Gobi, Enkhbileg Dulamtseren, Adiya Yadamjav, Dovchindorj Ganbold, Mijidorj Batmunkh Jan 2007

Current Status Of The Khulan (Equus Hemionus) In The Trans-Altai Gobi, Enkhbileg Dulamtseren, Adiya Yadamjav, Dovchindorj Ganbold, Mijidorj Batmunkh

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

Since 1975, 25 wildlife surveys have been conducted in the Trans-Altai Gobi. In this paper we summarize results from the last 11 surveys, conducted between October 2000 and April 2005, and discuss our findings together with results from previous surveys.


Morphology, Reproduction And Mortality Of Equus Hemionus Hemionus In Mongolia, Annegret Stubbe, Michael Stubbe, Nyamsuren Batsaikhan Jan 2007

Morphology, Reproduction And Mortality Of Equus Hemionus Hemionus In Mongolia, Annegret Stubbe, Michael Stubbe, Nyamsuren Batsaikhan

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

There are collected materials on morphology, reproduction rate, and mortality of Dschiggetajs Equus h. hemionus between 2001 and 2006 in the South Gobi of Mongolia. It were found 794 skeletons of wild asses, 95% of these were pouched, ⅔ of them in winter coat. Pouching was also located in the protected areas of this region. The main living resources of Equus hemionus are registered in the South eastern Gobi. For the first time statistical data on morphology measurements of body length, tail and tuft, ear length, and hoofs are given. There are no significant differences between the sexes. The reproduction …


Kulan (Equus Hemionus Pallas 1775) In Turkmenistan, Victor S. Lukarevskiy, Yu. K. Gorelov Jan 2007

Kulan (Equus Hemionus Pallas 1775) In Turkmenistan, Victor S. Lukarevskiy, Yu. K. Gorelov

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

The kulan (Equus hemionus kulan) is the only odd-toed ungulate left in the wild in northern Eurasia. In the 1930s, the kulan survived in southern Turkmenistan only. In the 1940s, kulans were found only in an area named Badkhyz in Turkmenistan. To conserve the last natural population of this subspecies of kulan the Badkhyz Natural Reserve was established in 1941. The historical and contemporary distribution, fluctuation in numbers, conservation and sci research of kulan populations in the Badkhyz Natural reserve are reviewed in this paper.


Numbers, Distribution And Social Structure Of Kiang (Equus Kiang Moorcroft 1841) Population In The Southwestern Part Of Tibet, China, Natalia V. Paklina, Chris Van Orden Jan 2007

Numbers, Distribution And Social Structure Of Kiang (Equus Kiang Moorcroft 1841) Population In The Southwestern Part Of Tibet, China, Natalia V. Paklina, Chris Van Orden

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

In September - October 1998 we made an extensive survey in southwest Tibet to study numbers, distribution and social structure of the kiang population in this remote part of its range. Kiangs were sighted between 29º 40’ and 32º 50’ N, and 81º- 86º E. They preferred broad flat valleys with lakes at an altitude from 4,000 up to 5,000 m. Small kiang groups and solitary animals were sighted in Transhimalaya. There were no kiangs in Tsangpo (Brahmaputra) River valley, in the sand desert near Ali and in the Clay Mountains near Tsada. Seven old kiang corpses were found along …


Beiträge Zur Ökologie Und Verbreitung Der Steppenwühlmaus Microtus Brandti Radde, 1861 In Der Mongolei = Ecology And Distribution Of The Steppe Vole Microtus Brandti Radde, 1861 In Mongolia, N. Dawaa, Michael Stubbe, Annegret Stubbe Jan 2005

Beiträge Zur Ökologie Und Verbreitung Der Steppenwühlmaus Microtus Brandti Radde, 1861 In Der Mongolei = Ecology And Distribution Of The Steppe Vole Microtus Brandti Radde, 1861 In Mongolia, N. Dawaa, Michael Stubbe, Annegret Stubbe

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

Microtus brandti is one of the most important pest species of Mongolian rodents. Since the publication of Bannikov (1954) the area of expansion is increased, in the Archangaj-Aimag 200 km westward, in the Central Aimag 70 km to the North and in the north-eastern part of Dornogov’- Aimag about 110 km to the South. In years of gradation the plant cover was exterminated up to 100%. We can distinguish a zone of exposed harmfulness with a damage of 70-100%. In this region 16 great centers of infestation were listed. Between 1925 and 1985 six important calamities were noticed, in intervals …


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 Jan 2005

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 …
