Conservation Biology, EarlyView.Abstract Knowledge of species distributions is essential for informing policies on nature conservation and restoration. However, updating them on a regular basis and doing so in a harmonized manner at the international level is difficult. The European Bird Census Council integrated national monitoring data covering 5 years to update farmland bird ...

Conservation Biology, EarlyView.Abstract Procedural, distributional, recognitional, and epistemic justice aspects of conservation interventions are well documented in contexts where pastoralism is a key livelihood and way of life. Geospatial analyses and representations of wildlife conservation and restoration that are increasingly applied in pastoralist rangeland socioecological ...

, 1985 本文讨论磁场中中等低气压弧光放电与辉光放电的正柱理论。文献[1]是给定放电中间参数后,假定中性气体运动,研究放电现象.本文仍假定中性气体运动,但给出初始放电参数,补充两个积分关系,建立了初始放电参数与中间参数的关系。给出这个问题完整的数学提法。用数值方法求解。文献[1]相当于第一次迭代。结果表明 ...

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.

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.

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.

四川大学学报. 自然科学版, 1979 关于丢番图方程x4-Dy2=1,D>0,且不是平方数,（1）Ljunggren,Cohn和本文作者都有过不少工作,现简述如下:1.1942年,Ljunggren证明了丢番图方程（1）最多只有二组正整数解（x,y）。2.1966年,Ljunggren证明了,当D=ρ是一个奇素数时,则丢番图方程（1）在ρ≠5,29时,没有正整数解。在ρ=5时,仅有正整数解x=3,y=4,在ρ=29时,仅有正整数解x=99,y=1820。

Gongye shui chuli, 2021 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。
