Abstract Reversing ongoing biodiversity loss requires effectively managing anthropogenic threats. Although conservation actions can mitigate these threats, prioritizing and targeting such actions remain challenging because species respond differently depending on the nature of the threats and their biological traits.

Comprehensive and representative conservation planning for biodiversity of ice‐free Antarctica
Abstract Antarctica is designated as a natural reserve devoted to peace and science, with Antarctic Specially Protected Areas (ASPAs) serving as the primary instrument for area‐based biodiversity protection. However, the existing ASPA network lacks the comprehensiveness and representativeness required under Annex V, Article 3(2), of the Madrid Protocol.

Using the capabilities approach to achieve people‐centered conservation
Abstract Top‐down interventions carried out by state and nonstate institutions to conserve biodiversity and improve the lives of forest‐proximate people (FPP) in the Global South tend to reflect economistic understandings of human well‐being. More progressive and people‐centered conservation projects are guided by normative visions of how the world ...

文章中设计的四象限InGaAs雪崩光电二极管(Avalanche Photo Diode,APD)的管芯结构采用正入光式平面型结构,而材料结构采用吸收区、倍增区渐变分离的APD结构,在对响应时间、暗电流和响应度等参数进行计算与分析的基础上,优化了器件结构参数。试验结果表明,其响应时间≤1.5 ns,响应度≥9.5 A/W,暗电流≤40 nA,可靠性设计时使PN结和倍增层均在器件表面以下,可有效抑制器件表面漏电流,提高器件的可靠性。

Optimizing biodiversity offsetting for habitat succession and colonization dynamics
Abstract Biodiversity offsetting aims to compensate for ecological losses from development through conservation and restoration. However, its long‐term outcomes under repeated impact–offset cycles remain uncertain. Using a conceptual forest succession model, we evaluated how offset outcomes are affected by interactions among compensation scale ...

基于在pH=5.5的六次甲基四胺缓冲液介质中,氟离子对铬天青S与铝离子络合的阻抑作用,建立了测定微量氟的褪色光度法。利用响应面法优化测定条件,以反应时间、Al3+用量及铬天青S用量为影响因子,组合设计建立数学模型,以吸光度值作为响应值,进行响应面法分析。得到最佳测定条件:反应时间为66.17 s、Al3+用量为6.47 mL、铬天青S用量为5.19 mL,在此条件下,吸光度的实测值为0.687 7,相对误差为0.044%,RSD(n=3)=1.24%。

粗糙度是影响坡面流水动力特性的关键因子,为探究渐变粗糙度影响下坡面流水力特性,采用粒子图像测速技术(particle image velocimetry, PIV)观测并分析3组流量下渐变粗糙床面下坡面流的流速轮廓线、紊动强度、雷诺应力和壁面切应力的变化规律。结果表明:(1)流速随粗糙度增加而减小;拟合无量纲流速得到流速分布对数公式,粗糙度增大与拟合常数A成反比,与积分系数B成正比。(2)渐变地表粗糙度流向紊动强度与光滑床面坡面流变化趋势相似。流向紊动强度随相对水深的增大而减小。随着粗糙度增大 ...

Learning Styles, Engagement and Anxiety in AI‐Mediated Writing: A Multimodal Feedback Study
ABSTRACT Artificial intelligence (AI) tools now permeate English academic writing. However, evidence on how feedback modalities align with student differences and with psychological mechanisms remains limited. Prior work often reduced learning styles to simple matches with delivery modes and treated learning engagement and writing anxiety as peripheral.
