Risks of concealing environmental degradation
Conservation Biology, EarlyView.Abstract Current practice seeks to conceal the visual impact of land‐use change (i.e., development). Six percent of development impact assessments in Australia and 14% of the World Bank's assessments recommend visual impact mitigation. This mitigation results in, for example, vegetated buffer strips alongside cleared agricultural areas and earthen ...

Changes in the transformative potential of action proposals in Finnish Red Lists from 1986 to 2019
Conservation Biology, EarlyView.Abstract Red lists provide critical knowledge regarding biodiversity decline, especially in Finland, where broad assessments have been made regularly since the 1980s. They deliver information on the threat status of species and ecosystems, propose actions to guide conservation policy, and have the potential to spur transformative change.

, 2018 随着人口的持续增长,人类经济活动对自然资源的利用强度不断升级以及全球气候变暖,全球物种正以前所未有的速度丧失,生物多样性成为了全球关注的热点问题。传统生物多样性研究以地面调查方法为主,重点关注物种或样地水平,但无法满足景观尺度、区域尺度以及全球尺度的生物多样性保护和评估需求。遥感作为获取生物多样性信息的另一种手段,近年来在生物多样性领域发展迅速,其覆盖广、序列性以及可重复性等特点使之在大尺度生物多样性监测和制图以及评估方面具有极大优势。本文主要通过文献收集整理,从观测手段、研究尺度 ...

How identity bias affects perceptions of conservation messages on social media
Conservation Biology, EarlyView.Abstract Public support is essential for conservation, as public opinion can influence decision‐making and policy. Therefore, understanding whether bias toward conservationists due to their identity (identity bias) affects their perceived credibility and support for their recommendations is important.

Shuitu Baochi Xuebao, 2001 用数量分析的方法研究了关帝山庞泉沟主要森林群落华北落叶松林和云杉林及其交错区的植物多样性.结果表明,随海拔高度的变化,群落的植物多样性指数呈降低趋势;Pielou均匀度指数乔木层呈降低趋势,而灌木层和草本层的变化不太明显.群落交错区的植物多样性明显增加.不同的生长型其多样性的变化表现出不同的特征.群落的β多样性表现出比较复杂的变化趋势.随海拔高度的变化其基本可以分为3个区段,在每个区段表现出的不同特征显示了群落及其交错区物种多样性的变化特征.

Scientists’ warning on the global destruction of rock outcrop ecosystems
Conservation Biology, EarlyView.Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

Twelve principles for successful governance of community‐based coastal marine restoration
Conservation Biology, EarlyView.Abstract Global agreements, such as the Global Biodiversity Framework, call for urgent, large‐scale action to halt biodiversity loss through a whole‐of‐society approach. Community‐based restoration can play a crucial role in achieving this goal, yet there remains limited understanding of what makes these projects effective and sustainable.

, 2014 揭示导致生物体形态和结构多样性产生的原因和机制,是进化生物学研究的重要内容。进化发育生物学的研究表明,许多复杂的形态结构及其多样性,都是通过对古老调控网络的修饰或改造来完成的。也就是说,生物体形态和结构的多样化并不是像以前认为的是由基因编码区的变化造成的,而更多的是取决于基因的调控进化。作为控制基因表达的关键组分,基因调控区的顺式调控元件通过与特定反式作用因子结合,精细调控基因表达的时、空和量。因此,调控元件的获得、丢失、修饰或者改变都能引起基因表达模式的变化,是形态和结构多样性产生的主要原因 ...
