There were 8 gliadin and 3 high_molecular_weight (HMW)_glutenin patterns in 14 Yunnan hulled wheat ( Triticum aestivum ssp. yunnanese King) accessions, 9 gliadin and 4 HMW_glutenin patterns in 9 Tibetan weedrace ( T. aestivum ssp. tibetanum Shao ) accessions, and 9 gliadin and 5 HMW_glutenin patterns in 9 Xinjiang rice wheat ( T. petropavlovskyi Udacz. et Migusch.) accessions. One accession (i.e. Daomai 2) carried new subunits 2.1+10.1 encoded by Glu_D1. Among the three Chinese endemic wheat groups, a total of 10, 14 and 11 alleles at Gli_1 locus; 11, 14 and 12 alleles at Gli_2 locus; and 5, 6 and 8 alleles at Glu_1 locus were identified, respectively. Among Yunnan hulled wheat, Tibetan weedrace and Xinjiang rice wheat, the Nei's genetic variation indexes were 0.3798, 0.5625 and 0.5693, respectively. These results suggested that Tibetan weedrace and Xinjiang rice wheat had higher genetic diversity than Yunnan hulled wheat.展开更多

To analyze the perception and attitudes of local communities, the Participatory Rural Appraisal (PRA) was used in the investigation of 423 interviewees from 22 villages in Xishuangbanna from July 2009 to February 2010. The results indicated that local communities had their views on the elephant-related problems. In field survey, we found that 66.5% of interviewees were willing to support, participate in, and assist in the conservation of wild elephants;33.5% of interviewees were opposed or indifferent to such conservation, because their livelihoods and even their lives were endangered by wild elephants. These views and attitudes were influenced by local communities′perception of HEC, education level, gender and self-interest. Therefore, it is necessary to analyze the diverse views among local communities and balance profits and costs in addressing HEC.展开更多

There have been83 species（22 families, 8 orders） of wild mammals illegally traded and smuggled in China, mainly found in the southwest border, especially in Yunnan and Guangxi.Smuggling has seriously affected the ecological security of China, so it is necessary to intensify efforts to fight such crime, and enhance the people’s awareness of wildlife protection.展开更多

The objective is to research this temporary residency for researchers through the meanings that characterize it as a Brazilian territory in Paris and through the very belonging to the category elite as a peculiarity of its residents. The author wish to analyze the international circulation of students and researchers that live there and have an educational experience of multiple dimensions as experiences of deterritorialization of identities and its consequences in a housing space which is at the same time in public and private. Based on documental analysis and ethnographic fieldwork, the paper presents some aspects of the history and the everyday life of the Maison du Bresil and Paris＇ Cite Internationale Universitaire. Also, it intends to show how the meanings of Brazilianness are used as support for the identity crisis lived by the members of a supposed Brazilian elite in Paris, as it analyzes the particularities of the mediations established by the residents of the Maison du Bresil, in the formation and international insertion of some researchers.展开更多

This combination of policies has stimulated socioeconomic growth and ecological improvement in China＇s western regions and has effectively curbed the runaway gap between the east and west, even causing the gap to begin shrinking gradually. However, it should be noted that the development gap between China＇s eastern and western regions remains significant, as demonstrated by the west＇s low level of industrial^commercial development, local governments＇ limited capacity to provide public services, and endemic rural poverty. Thus, achieving the targets outlined in the western regional development program remains a challenging task. In the future, China＇s western development program should emphasize a higher standard of living and coordinated, inclusive growth across regions.展开更多
