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.

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 ...

Dianci bileiqi, 2017 组合波是电涌保护器性能试验与浪涌抗扰度试验的必备波形,但是目前IEC和IEEE相关规范针对组合波的定义存在一定差别,主要在于波形是否存在负峰,因此需要组合波负峰存在与否对浪涌防护的影响。利用EMTP软件搭建两种组合波发生电路,分别产生不存在负峰与存在负峰的组合波,同时结合IEEE压敏电阻模型进行仿真冲击,分析压敏电阻残压与吸收能量的差异。最后讨论不同负载性质下连接电缆长度对两种组合波冲击后负载端电压的影响。分析结果表明:组合波负峰存在与否对压敏电阻残压数值影响不大,但对残压波形影响较大 ...

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.

Conservation Biology, EarlyView.Abstract Ecological niche models (ENMs) are used to assess the abiotic preferences of species by linking their occurrences to the environmental conditions in which they live. We developed a fossil‐informed ENM framework that integrates mid‐Holocene and modern occurrences to test niche stability and reconstruct abiotic niche characteristics for four ...

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
