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.


Environmental Adaptations Of The Gobi Desert Plants In Mongolia: An Example Of C4-Plants, Ts. Tsendeekhuu, Clanton Candler Black Jan 2005

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 …


Reproductive Ecology Of Two Common Woody Species, Juniperus Sabina And Artemisia Santolinifolia, In Mountain Steppes Of Southern Mongolia, Katrin Ronnenberg Jan 2005

Reproductive Ecology Of Two Common Woody Species, Juniperus Sabina And Artemisia Santolinifolia, In Mountain Steppes Of Southern Mongolia, Katrin Ronnenberg

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

The present study describes the reproductive ecology of the prostrate shrub Juniperus sabina and the dwarf shrub Artemisia santolinifolia in dry mountain steppes of southern Mongolia. Whereas stands of the juniper are located at the drought limit of the genus’ distributional range, the genus Artemisia is typical of central Asian drylands. Both species produce large numbers of reproductive organs. For Juniperus sabina, however, only 2.5% of the morphologically intact seeds were found to be viable. Correspondingly, neither seedlings nor saplings were found in the field, and recruitment by reseeding happens at most rarely under the present climatic conditions.

Instead, …


Caracterización Bromatológica Y Evaluación De Diferentes Niveles De Inclusión De Morera (Morus Alba L.) Y Sauco (Sambucus Nigra L.), En La Alimentación De Conejos En Ceba, Maria Carolina Blanco Causil, Magda Lucia Sierra Moreno Jan 2005

Zootecnia

Actualmente las producciones animales tecnificadas dependen en gran mayoría de alimentos balanceados, estando sujetos a costos que imponga el comercio internacional, esta dependencia afecta las ganancias y se hace urgente buscar alternativas que provean soluciones. En esta investigación se seleccionaron 50 conejos Nueva Zelanda blanco de +/- 750 gr. De peso vivo, según diseño completamente al azar, con 10 unidades experimentales por tratamiento, para evaluar el efecto de la inclusión de los forrajes Morus alba L. y Sambucus nigra L. en sustitución del alimento balanceado comercial (ABC). Los tratamientos consistieron en 5 dietas experimentales, una control a base de ABC …
