Role of funders in embedding tests in conservation practice
Conservation Biology, EarlyView.Abstract Effective conservation practice requires decisions based on reliable and relevant evidence, but significant gaps in the evidence base exist. Incorporating well‐designed tests of the effectiveness of interventions for biodiversity in conservation projects is one of the best ways to scale up the rate of evidence generation.

Zhejiang Daxue xuebao. Lixue ban, 2006 视差估计与补偿是立体视频图像压缩编码中的关键技术.本文分析了立体摄像系统视差分布的约束条件（外极线约束、方向性约束等）和视差矢量的相关性（帧内视差矢量的空域相关性和帧间视差矢量的时域相关性），并结合H. 264标准中的多种块选择模式之间的相关性，提出了基于H. 264的立体视频编码的视差估计快速算法.实验结果表明，提出的快速算法能有效地降低视差估计的计算复杂度.

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.

Shuitu Baochi Xuebao, 1994 该文通过对海堤林带树木根系及土壤抗冲，抗蚀和渗透性的测定分析，发现同一地段土壤的抗冲，抗蚀指数表土层大于底土层。树木根系，尤其是根径≤２ｍｍ的细根有较强的固特土壤功能，抗冲指数与根长，根量间有明显的相关性，单相关系数分别为０．９３２６和０．８２５６。吸机质含量高的土壤抗蚀性强，抗蚀指数大，与有机含量间的相关系为０．８９３１，与细根的根长和根量的相关性相对较低，单相关系数分别为０．８２１６和０ ...

Effects of restoration practices on biodiversity in temperate and boreal forests
Conservation Biology, EarlyView.Abstract Several restoration practices are used to mitigate and compensate for the negative effects of large‐scale forestry on biodiversity in temperate and boreal forests. A comprehensive synthesis of the benefits of these practices across taxa is missing. We conducted a systematic review and meta‐analysis on this topic.

Assessing and strengthening community‐based coastal governance
Conservation Biology, EarlyView.Abstract Community‐based coastal governance is essential for biodiversity conservation and sustainable livelihoods, yet many communities continue to face significant challenges in establishing and sustaining effective governance systems. We sought to improve understanding of the current status of community‐based coastal governance across five countries
