A new species of Malus in China,Malus shizongensis Liu sp. nov

Based on morphological, molecular biological, and molecular systematic studies, we describe here a new species of Malus from Yunnan, China. We compared the morphology of this new species, Malus shizongensis Liu sp. nov, with three Malus species, including M. hupehensis, M. baccata, and M. micromalus. Although the appearance of M. shizongensis was similar to these three species, it differed in height, branch color, branch hair, and flower color. To better identify the taxonomy of this new species, genome of M. shizongensis and that of seven Malus species, including M. prunifolia, M. sylvestris, M. sieversii, M. hupehensis, M. baccata, M. robusta, and M. micromalus were analyzed. A phylogenetic tree based on genome analysis indicated that M. shizongensis was close to M. hupehensis. Furthermore, M. shizongensis had its species-specific SNPs, and the number of species-specific SNPs was similar to that of three close species(M. hupehensis, M. baccata, and M. micromalus). Based on the above information, we named this new species as M. shizongensis Liu sp. nov.

城镇化发展中的小城镇特色建设问题研究

集中发展小城镇是我国城镇化发展的一个重要选择。当前我国小城镇特色建设面临着特色挖掘不突出、特色彰显能力弱、基础设施公共服务功能弱、创新精神不足以及缺乏活力等问题。小城镇特色建设必须坚持以适合人民生活为宗旨，以大中城市周边合理布局为基础并注重乡土重建，充分发挥原住民在小城镇特色挖掘上的主体作用，注重通过创新精神去激活发展动力，在保护和开发并重的前提下发挥政府搭建平台、城镇居民共同参与、开发资本“走进来”的三方协同作用来加强小城镇特色建设。     

秦岭南麓新分布小太平鸟迁徙期食性初步观察

2011-2013年冬季,作者采用分组全天跟踪的方法,调查小太平鸟迁徙期活动特征和食性。结果证明:小太平鸟冬季由北向南成群迁徙过程中,会在某个生境优良的区域停留取食9~15日、成群活动在树冠上部。小太平鸟在迁徙期停留区域取食植物果实种类有20种,有人工栽培树种果实,也有野生树种果实。今后应持续迁移路线、停歇地、种群动态监测。     

Analysis on Function Orientation and Development Countermeasures of New Agricultural Business Entities
