PREMISE OF THE STUDY Microsatellite primers were developed for Parthenium hysterophorus to investigate its genetic structure and genetic diversity. METHODS AND RESULTS Using the combined biotin capture method, 15 microsatellite primer sets were isolated and characterized. All markers showed polymorphism, and the number of alleles per locus ranged from two(More)
The integration between vegetation data, human disturbance factors, and geo-spatial data (Digital Elevation Model (DEM) and image data) is a particular challenge for vegetation mapping in mountainous areas. The present study aimed to incorporate the relationships between species distribution (or vegetation spatial distribution pattern) and topography and(More)
The mean temperature of the growing season has been found to correlate with treeline position across the globe, but regional variation still needs to be explained. In the present study, we explored how the elevation of the alpine treeline varies with slope exposure and the distinct influence of the summer monsoon in the Three Parallel Rivers region of SW(More)
The Meili Snow Mountain (28 degrees 20'-28 degrees 33'N, 98 degrees 30'-8 degrees 52'E) is a very famous mountain in Northwest Yunnan of China by its rich and well protected biodiversity and Tibetan cultural diversity. By applying 3S (RS-Remote Sensing, GIS-Geography Information System, GPS-Global Position System) technology, the 1:50000 vegetation map of(More)
PREMISE OF THE STUDY Tithonia diversifolia (Asteraceae) is an invasive plant species that can outcompete natives and thus poses a great threat to biodiversity in introduced areas. Here, expressed sequence tag-simple sequence repeat (EST-SSR) markers were developed and characterized. METHODS AND RESULTS Sixteen polymorphic microsatellite loci were isolated(More)
BACKGROUND Livestock rearing is one of the oldest and most important types of smallholder farming worldwide. The sustainability of livestock production depends on the efficient utilization of locally available resources. Some traditional methods of raising livestock may offer valuable lessons in this regard. This study documented and evaluated local(More)
The use of native species in forest restoration has been increasingly recognized as an effective means of restoring ecosystem functions and biodiversity to degraded areas across the world. However, successful selection of species adapted to local conditions requires specific knowledge which is often lacking, especially in developing countries. In order to(More)
In mountainous areas, the landscape spatial pattern is affected by topography and human activities. To better understand topographic influences on the vegetation structure in the landscape mosaic and interpret the ecological implications of spatial patterns, the relationships between topographic features and landscape pattern indices (LPIs) should be(More)
