Abstract As the coverage of area‐based conservation increases across the globe, it is critical to improve understanding of the social and ecological outcomes of such measures and the pathways to their outcomes. A social–ecological systems approach to monitoring and evaluation is increasingly advocated; yet, applications remain scarce.

Policy instruments attitudes and support for government responses against Covid‐19
Abstract An individual's political attitudes have been documented as the most important predictor of acceptance of government measures against the COVID‐19 pandemic. Their effect, however, is somewhat unclear and cannot be reduced to one dimension. In this article, we test whether general attitudes toward policy instruments might, together with left ...

Integrating adult occurrence and reproduction data to identify conservation measures for amphibians
Abstract Monitoring programs are pivotal to establishing sound management. Due to economic, logistic, and time limitations, monitoring programs often overlook differences among life‐history stages. However, species occurrence does not necessarily mean population viability, and it is unclear to what extent monitoring programs that do not consider ...

某体育场为空间索桁架结构,由刚性外压环梁、内环索、上径向索、下径向索、吊索、压杆和柱间交叉支撑组成。该工程索桁架共有38榀,其跨度大、悬挑长,榀数多,呈空间形态及整体的受力较为复杂。为减少施工搭设支架费用,缩短工期,根据工程特点设计了针对该工程的施工方法。利用ANSYS有限元软件分析得到支承结构在各个关键施工阶段的变形规律及受力特点,并用FBG传感器对结构施工张拉阶段预应力变化做实时检测,为施工过程提供依据。提出的施工方法及监测手段可为类似结构的施工提供参考。

Creating a more inclusive approach to wildlife trade management
Abstract Global wildlife trade involves a diverse array of species. Although sustainable trade underpins livelihoods for communities worldwide, unsustainable trade, whether legal or illegal, threatens thousands of species and can lead to extinctions.
