卫星及通信技术考察报告

为了解法德两国卫星及通信技术应用情况,学习借鉴其在减灾救灾领域成功的应用经验,2006年12月中旬,民政部国家减灾中心组团赴法德两国进行了为期10天的考察。考察团一行10人,分别来自民政部国家减灾中心、中国科学院电子科学     

抗稻瘟病基因Pi-2(t)紧密连锁的SSR标记的筛选与应用

根据已报道的双侧连锁标记并利用已公布的水稻基因组序列信息,在广谱抗稻瘟病基因Pi-2（t)的附近找到了一个新的SSR标记,记为SRM24,估计它与Pi-2（t)间的距离大约只有0．5cM或43kb。利用该标记,成功地将Pi-2（t)从供体材料5173导入到迄今广泛使用的雄性不育保持系珍汕97B中,获得了一批携有Pi-2（t)的珍汕97B近等基因系。     

引进和使用外籍教师应注意的问题

我国各级各类学校目前都在引进外籍教师开设外语口语课,但对于外教的使用和管理还存在着误区,一些学校为此蒙受了损失.根据长期与外教接触,提出了对于外籍教师的引进要严把质量关,要为外教提供良好的生活、工作条件,严格管理外教教学观点.     

澳大利亚的治沙与林业可持续经营

系统介绍了澳大利业关于沙化土地项目管理和林业可持续经营技术方面的主要做法,分析指出澳大利亚政府十分重视荒漠化防治问题,依靠科技手段强化治沙工程项目管理,加强预警监测水平,提出我国长期坚持保护天然林、大力发展集约经营人工林、重视治沙项目的管理和科技人才培养、遵循自然规律治理沙化土地等建议。     

棕背伯劳繁殖期领域性初步研究

棕背伯劳在繁殖活动中表现出很强的领域性。本文从鸣叫、飞行、栖位占据、领域面积变化和种间关系等５个方面阐述了棕背伯劳的领域性，并讨论了繁殖期各阶段领域性的变化。首次提出了领域栖位和非领域栖位的概念与划分，并明确了领域鸣叫和领域飞行等概念。     

The first report on natural Enterocytozoon bieneusi and Encephalitozoon spp. infections in wild East-European House Mice (Mus musculus musculus) and West-European House Mice (M. m. domesticus) in a hybrid zone across the Czech Republic-Germany border

To determine the occurrence of potentially human pathogenic microsporidia (Enterocytozoon bieneusi and Encephalitozoon spp.) in wild mice, we examined 289 East-European House Mice (Mus musculus musculus) and West-European House Mice (M. m. domesticus) trapped at 74 localities in an area across the Czech-German border. Microsporidia were detected at 33 localities, in 34% of M. m. musculus and 33% of M. m. domesticus examined specimens. Single-species infection was detected in 23 mice for E. hellem, 42 mice for E. cuniculi and 25 mice for E. bieneusi. No Encephalitozoon intestinalis positive animals were identified. Moreover, co-infections were detected in 6 animals; E. bieneusi co-existed with E. cuniculi or E. hellem in 3 mice. The natural infection of E. hellem has never been recorded in mice before. No differences were found by a statistical analysis of microsporidia occurrence between the House Mouse subspecies. Although the gender-dependent infestation of microsporidia was statistically supported in M. m. musculus, no significant differences were observed when the occurrence of microsporidia was estimated for all males and females irrespective of the House Mouse subspecies. The results of this report document the low host specificity of detected microsporidia species and imply the importance of synanthropic rodents as a potential source of human microsporidial infection.
