Servicesheds connect people to the landscapes upon which they depend
Abstract Ecosystem services (ES) are benefits people receive from nature. To sustain these benefits, we need to spatially connect communities benefitting from specific ES with landscape features that generate the ES. A variety of process‐based models support ES assessments by estimating the biophysical supply of ES that comes from landscapes.

Graphical abstract The mechanical responses and structure variations of Ta80Co20 nanoscale metallic glass (MG) film samples upon cryogenic thermal cycling (CTC) treatment were studied. The simultaneous improvements of strength and deformation ability bring about a super‐high strength of 4.5 GPa and a large plastic strain of about 80% after CTC ...

A framework for promoting disciplinary diversity and inclusion through epistemic justice
Abstract Integrating diverse disciplines and knowledge practices into conservation offers new insights into the complex socioecological dynamics of conservation challenges and how to address them. Integration, however, is not simple; disciplines differ widely in their epistemic and professional commitments, theories, methods, applications, practices ...

Adaptive spatiotemporal management to reduce shark bycatch in tuna fisheries
Abstract Purse‐seine tropical tuna fishing in the eastern tropical Pacific Ocean (EPO) results in the bycatch of several sensitive species groups, including elasmobranchs. Effective ecosystem management balances conservation and resource use and requires considering trade‐offs and synergies.

Wildlife mortality risk posed by high and low traffic roads
Abstract Wildlife mortality due to collisions with vehicles (roadkill) is one of the predominant negative effects exerted by roads on many wildlife species. Reducing roadkill is therefore a major component of wildlife conservation. Roadkill is affected by various factors, including road attributes and traffic volume.

为满足变压器式可控电抗器(controllable reactor of transformer type,CRT)"高阻抗、弱耦合"的设计要求,结合磁集成技术,提出一种结构更为简单、对制作工艺要求更低的CRT实用化本体结构。该结构通过在工作绕组与控制绕组间设置漏磁铁心,使变压器与限流电抗集成在一起构成一个具有"高阻抗"的基本独立单元。将这样多个基本独立单元组合并联构成CRT本体,可实现"弱耦合"。根据对基本独立单元的磁路分析,推导出工作绕组电流的一般表达式以及建立其等效电路,并以实验室样机制作为对象 ...
