Osnabrück Botanical Expeditions To Mongolia, Barbara Neuffer, Nikolai Friesen, Batlai Oyuntsetseg, Tseden Jamsran, Herbert Hurka

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

Three botanical expeditions to Mongolia have been undertaken by the Botany Department of the University of Osnabrück in cooperation with the Botany Department of the National Mongolian University of Ulaanbaatar. The first expedition in 2000 took us to the Mongolian Altay, the second in 2001 to the Gobi and Gobi Altay, and the third in 2010 to East Mongolia including the Khingan Mts. (Numrug). In 2000, we were the first botanists being allowed to enter the border area between China and Russia in the Mongolian Altay since a long time, because this had been a prohibited area for decades. We …

The research shows that widely used key measures of vegetation structure (species diversity, projected cover and above-ground phytomass) are not always suitable as indicators of pasture degradation. Based on an analysis above-ground phytomass composition, new quantitative indices are offered that give a more realistic picture of rangeland condition in Mongolia.

On The Importance Of Pollen Morphology In Classification Of Chenopodiaceae In Mongolia, Gaadan Punsalpaamuu, Frank Schluetz, Tserendorj Gegeensuvd, Davaadorj Saindovdon

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

The pollen morphology of 18 species from 12 genera of Chenopodiaceae native to Mongolia was studied. Plants were collected during field courses and research projects on useful plants and are deposited in the Herbarium of the Mongolian State University of Education. Chemical preparation was carried out in the Palynological Laboratories at the School of Natural Sciences of the Mongolian State University of Education and the Department of Palynology and Climate Dynamics of the University of Göttingen in Germany. The results show, that all investigated species are distinguishable in terms of pollen morphology bases on their pollen grain sizes, exine thickness …

Environmental Adaptations Of The Gobi Desert Plants In Mongolia: An Example Of C4-Plants, Ts. Tsendeekhuu, Clanton Candler Black

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

This paper presents the results of our studies on the ecological adaptations and geographical distribution of plants with C4-photosynthesis in Mongolia using ¹³C isotope discrimination.

Previous studies identified about 80 C4-species in 8 families in the Mongolian flora. Our investigations lead to the identification of four additional species, which can be regarded as C4-plants. Orostachys spinosa (-16.26‰ ¹³C), O. thyrsiflora (-16.86‰ ¹³C), O. fimbriata (-16.15‰ ¹³C), and Euphorbia humifusa (-23.29‰ ¹³C). However, as the discrimination level for Euphorbia humifusa is very similar to that of C3-plants it may be switching between C3 and C4 types …

Flora Of The Gurvan Saykhan Mountains, Tseden Jamsran, Batlai Oyuntsetseg, Radnaakhand Tungalag

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

Although two major books have been published on the Mongolian flora regional data are often still lacking due to the vast expanses of the country. Therefore we used published information and data from our own fieldwork to compile a relatively comprehensive inventory of the flora of the Gobi Gurvan Saykhan mountains in southern Mongolia.
