Threats to and management of Natura 2000 protected areas relative to agricultural practices
Conservation Biology, EarlyView.Abstract The Natura 2000 (N2K) network combines biodiversity protection and socioeconomic targets. Human activities, such as agricultural practices, can affect biodiversity in N2K sites in diverse ways. Limiting activities with negative impacts while enforcing land management that supports biodiversity is crucial for effective conservation.

Shuitu Baochi Xuebao, 2006 目前常用的数学模型法和景观生态学方法，对揭示区域生态压力的现状和进行区域横向比较具有良好效果，但是缺乏历史纵向比较。景观生态背景值，是在综合了区域特定历史时期景观生态本底值和合理的人类活动两方面因素的基础上形成的。运用景观生态背景值作为景观生态压力评价的坐标起点，结合区域中主要的生态过程，通过对变化中的景观生态类型、格局与景观生态背景值的偏离程度来评价区域生态压力与安全，评价结果不仅能较明确地说明区域生态压力与安全现状的性质，同时清晰地揭示出人为因素对区域生态压力与安全状态的影响程度与性质。

辐冠苣苔属（苦苣苔科）一新替代名称——Radiaticorollarus Y. G. Wei, F. Wen & Lei Cai
Guangxi Zhiwu辐冠苣苔属为中国广东特有苦苣苔科单型属，因其具有苦苣苔科中相对比较少见的辐射状花冠裂片而得名。有学者提出因其属名Actinostephanus F. Wen, Y. G. Wei & L. F. Fu和已灭绝的化石浮游植物属名Actinostephanos Khursevich极其相似而易于混淆，应处理为晚出同名。依据2018年《国际藻类、菌物和植物命名法规（深圳法规）》，该文为该晚出同名拟定了一个新名称，即Radiaticorollarus Y. G. Wei, F.

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle
Conservation Biology, EarlyView.Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We
