Structured decision‐making as a framework to incorporate social equity into conservation decisions
Abstract Many conservation challenges require negotiating trade‐offs between the needs of different actors. Global frameworks such as the Kunming–Montreal Global Biodiversity Framework explicitly call for diverse participation and social equity in conservation decision‐making.

采用正交试验法研究不同电极、电压、电流对电化学去除污水中磷的影响。结果表明:磷的去除率随电压的增加而增大,电流的影响不显著。对于磷质量浓度为0.500 mg/L的中水,最佳电解条件为:铁作正极、铝作负极,电压25 V,电流0.5 A,电解时间40 min,磷去除率为96.0%。电解磷质量浓度为12.97 mg/L的废水,最佳电解条件为:铁作正极、铝作负极,电压30 V,电流1 A,电解时间为60 min,磷去除率为96.77%以上。处理后水中磷的浓度可达到国家排放标准和回用要求。

Abstract Qualitative approaches are increasingly applied in conservation social science, yet methodological reflection remains limited. Member checking, a process of returning findings to participants for feedback, is widely recognized outside conservation as a means to enhance rigor and reciprocity, but it is rarely reported in conservation research ...

Intact coastal nursery rearing amid climate‐driven phenological shifts in threatened salmon
Abstract Literature linking phenology to climate has proliferated in recent decades and shows that climate change has reorganized seasonal opportunities worldwide. However, this literature often quantifies changes in point measures of timing (e.g., beginnings and peaks) without context about duration (e.g., rearing season length) or performance (e.g ...

How endorser attributes influence conservation communication
Abstract Conservation communication often uses the celebrity endorsement strategy. However, robust evidence regarding its effectiveness is still limited. More importantly, practitioners do not have guidelines for selecting an ideal endorser because there is no clear consensus on what endorser attributes are most critical.

利用弱拟正规子群及S-弱拟正规子群,得到了有限群的可解性的一些新刻画.主要获得了下列结论:(i)若群G有两个不共轭的可解极大子群均在G中弱拟正规,则G可解;(ii)群G可解当且仅当G存在可解的极大子群在G中弱拟正规,且G与交错群A5、PSL2(7)及PSL3(3)无关.

The obsolescence of protected area categories in a polycrisis world
Abstract Current global conservation models face significant limitations in addressing the global polycrisis, and the constraints of the International Union for Conservation of Nature protected area (PA) classification system are part of the issue. The principles of the new conservation paradigm—governance, equity, and interculturality—are not viable ...

Early outcomes of England's new biodiversity offset market
Abstract Nature markets are being operationalized as a tool to address the biodiversity finance gap and achieve global biodiversity targets. However, there is limited understanding of how the outcomes of these markets align with biodiversity targets.
