In a narrow sense , Mongolian Plateau ranges over Tannu M t . , Sayan M t . , Khentei M t . and Yablonovy M t . to the north , Qilianshan M t . , Alashan M t . and Yinshan M t . to the south , Altai M t . to the west , and Great Khingan M t . to the east . In a broad sense , it also includes Ordos Plateau . Mongolian Plateau has a complex natural and historical condition , and unique natural environment . Under the particular environmental condition , forages went through a long process of natural selection , with a range of desirable characteristics acclimatized to the Mongolian Plateau . Different types of forages carry a varietGyroafmgiennetic information , and form genetic diversity of forages in the Mongolian Plateau . Among them , the endemic forages of eae are the most important . Materials and methods ‐ ‐ On the basis of many years�studies o‐n plant classification and flora in Inner Mongolia‐, we made an on‐ the spot scientific expedition in Mongolia ( Dornogobi , ９G‐o２b６i s２u０m０５ber , Tuv , Darhan , Selenge , Bulgan , Outer Khangai , Inner khangai , Dundgobi , Orkhon , Ulaanbaatar) onGAraumgiunsetae , .

The ‘needlegrasses’ are char- acterized by having single-flowered spikelets and stout, terminally-awned lem- mas. We conducted a molecular phylogenetic study of the Stipeae (including all genera except Anemanthele) using a total of 94 species (nine species were used as outgroups) based on five plastid DNA regions (trnK-5’matK, matK, trnHGUG-psbA, trnL5’-trnF, and ndhF) and a single nuclear DNA region (ITS).

Simpson The Eli Kirk Price Endowed Flora of Pennsylvania Intern Date: June 2008 Anstract: Solidago speciosa var. speciosa or “showy goldenrod” is a threatened Pennsylvania plant with only a handful of known populations. Little is known about the mechanisms this species employs to perpetuate a population. To understand the role that reproductive modes play in the limited distribution of this goldenrod and the relative importance of sexual reproduction and clonal growth, the genetic diversity, clonal structure and pollinator abundance of three Solidago speciosa var. speciosa populations from Montgomery County were investigated. To test the hypothesis that S. speciosa var. speciosa, like other goldenrods, is capable of clonal growth Inter- Simple Sequence Repeats were used. Ten primers have supported the importance of clonal growth in the FCL and FCU populations while a more complex reproductive history is needed to explain the BS population.

  • Population Genetic Structure and Evolutionary History Of
    Population genetic structure and evolutionary history of Psammochloa villosa (Trin.) Bor (Poaceae) revealed by AFLP marker Xu Su1 and Ting Lv2 1Qinghai Normal University 2Affiliation not available February 18, 2021 Abstract We sought to generate a preliminary demographic framework for Psammochloa villosa to support of future studies of this ecologically important desert grass species, its conservation, and sustainable utilization. Psammochloa villosa occurs in the Inner Mongolian Plateau where it is frequently the dominant species and is involved in sand stabilization and wind breaking. Here, we characterized the genetic diversity and structure of 210 individuals from 43 natural populations of P. villosa using amplified fragment length polymorphism (AFLP) markers. We obtained 1728 well-defined amplified bands from eight pairs of primers, of which 1654 bands (95.72%) were polymorphic.All these values indicate that there is abundant genetic diversity, but limited gene flow in P. villosa. However, an analysis of molecular variance (AMOVA) showed that genetic variation mainly exists within 43 populations of the species (64.16%), and we found that the most genetically similar populations were often not geographically adjacent. Thus, this suggests that the mechanisms of gene flow are surprisingly complex in the species and may occur over long distances. In addition, we predicted the distribution dynamics of P. villosa based on the spatial distribution modeling and found that its range has contracted continuously since the last inter-glacial period. We speculate that dry, cold climates have been critical in determining the geographic distribution of P. villosa during the Quaternary period. Our study provides new insights into the population genetics and evolutionary history of P.

Reinh.-Tüxen-Ges. 18, 117-128. Hannover 2006 Vegetation ecological features of dry Inner and Outer Mongolia - M.A. van Staalduinen & Marinus J.A. Werger, Utrecht - Zusammenfassung Der Vortrag befasst sich mit Wüsten, Halbwüsten und Trockensteppen im Gobi- Bereich im Süden der Republik Mongolien und im angrenzenden Norden von China, von der Provinz Inner Mongolia bis Gansu. Die natürlichen Bedingungen dieser Gebiete werden erläutert und ihre großräumigen Vegetationstypen kurz in ihrem Zusammenhang dargestellt. Der Bevölkerungsdruck und vor allem die Viehbestände haben in dieser Region in den letzten Jahrzehnten sehr stark zugenommen. Dies hat zu einer sehr verstärkten Desertifikation der Gebiete geführt. Ausgedehnte, heutzutage von Flugsand bedeckte Gebiete trugen bis vor wenigen Jahrzehnten unter viel gerin- gerem Überbeweidungsdruck noch halboffene Vegetationen auf stabilisierten Boden- oberflächen. Der Effekt der Überbeweidung auf die halboffene Vegetation zeigt sich zunächst in einer Änderung des Vegetationsdeckungsgrades und geht dann auch bald mit einer Verschiebung der Artenzusammensetzung einher. Eine der auffälligsten Änderungen in diesem Stadium der Überbeweidung ist die Ersetzung von büschelför- migen Stipa-Arten durch das Gras Leymus chinensis, das mittels Rhizomen wächst. Auch andere Rhizomgewächse breiten sich unter Überbeweidung aus. Dies hängt damit zusammen, dass Leymus im Vergleich zu Stipa ein bedeutend höheres kompen- satorisches Wachstum in Reaktion auf Abschneiden (Abfressen) hat.

Read Full License Page 1/24 Abstract Background: Researchers have rarely studied traditional botanical knowledge in Mongolia over the past 60 years, and existing studies had been based on the theory and methodology of ethnobotany. However, Russian scientists who studied plants in Mongolia in the 1940s and 1950s collected valuable historical records of indigenous knowledge and information on Mongolian herdsmen utilizing local wild plants. One of the most comprehensive works is titled: "Forage plants on grazing land and mowing grassland in the People's Republic of Mongolia" (FPM) by A. A. Yunatov (1909-1967). Yunatov’s work focused on forage plants in Mongolia from 1940 to 1951, which was published in 1954 as his early research. Later, the original FPM was translated into Chinese and Cyrillic Mongolian in 1958 and 1968, respectively. Materials: In addition to morphological characteristics, distribution, habitat, phenology, palatability and nutrition of forage plants, Yunatov recorded the local names, the folk understanding and evaluation of the forage value, as well as other relevant cultural meanings and the use of local wild plants in FPM through interviews.

Box 62000-00200, Nairobi, Kenya (Received November 3, 2008; Accepted December 2, 2009) ABSTRACT. Genetic variation and clonal diversity of seven natural populations of the rare, highly clonal marsh herb Sagittaria lichuanensis were investigated using inter-simple sequence repeat (ISSR) markers. Of the sixty-five ISSR primers screened, seven produced highly reproducible bands. Using these primers, a total of 76 DNA fragments were generated with 22 (29.0%) being polymorphic, indicating lower genetic variation at the species level compared to others in the same genus. With the use of 22 polymorphic markers, we were able to identify 9 genets among the 231 samples analyzed. The proportion of distinguishable genets (PD: mean 0.039), Simpson’s diversity index (D: mean 0.309), and evenness (E: mean 0.292) exhibited low levels of clonal diversity compared to other clonal plants. The result implies that sexual reproduction might not have played an important role in these populations.
