Biodiversity‐driven spatial conservation planning to delineate temporally stable regions
Conservation Biology, EarlyView.Abstract The accelerating loss of biodiversity underscores the critical need for effective conservation strategies, particularly in the face of climate change and anthropogenic pressures. We devised a conservation planning framework that adopts a temporal stacking approach to species distribution models and landscape connectivity analyses. These models

Gaoya dianqi, 2020 GIS回路中导电接触状态关系到GIS的安全运行。文中通过对GIS回路电阻特性的研究,指出了通过直流法测量回路电阻来评估GIS回路接触状态的不足,发现直流法在测量回路电阻时存在一定随机性,且直流法通流时间短、电流幅值小、没有交流电动力的影响,与实际运行时的设备状况相差较大,不能准确反映GIS回路接触的真实情况,也不能用于对GIS回路电接触劣化程度进行准确评估。为了探究实际运行中导体发热和电动力产生的振动等因素对电接触的影响,文中在GIS设备中通过交流电流进行温升试验,并利用交流法计算了温升过程中回路电阻 ...

Defining and identifying relevant stakeholders to advance effective conservation
Conservation Biology, EarlyView.The challenge of defining stakeholders in environmental science and an approach for refining existing definitions. Abstract Stakeholder is a contested term that has spawned a multitude of ad hoc definitions. The ambiguity of these definitions has oftentimes impeded transdisciplinary research in environmental governance and conservation science because ...

Using customs data to understand overlooked trade in non‐CITES birds between Africa and Asia
Conservation Biology, EarlyView.Abstract The international trade in live birds poses risks to animals, people, and biodiversity. To effectively mitigate these risks, decision‐makers require information on the volume, dynamics, and direction of trade. Despite Africa once being the largest exporter of birds by region, very little data exist on recent trade in live birds not listed on ...

A more‐than‐human political ecology of Indonesian songbird trade
Conservation Biology, EarlyView.Abstract Since its inception, conservation science has considered wildlife trade a problem. In focusing on conservation outcomes, conservationists almost completely ignore the welfare of traded animals and plants and the harms they endure. We developed a political ecology approach that incorporates the interconnectedness of people with animals and ...

わが国における外国クルーズ船社誘致策の展開と国際クルーズマーケットの変化 [PDF]
, 2020 外国クルーズ船社に対するわが国地方自治体によるマーケティング分野の政策・活動と、外国クルーズ船社の寄港の状況とその傾向を考察した。地方自治体は、商談会への参加をはじめとする多様なチャネルを活用した観光地・イベントの情報提供、モデルツアーの提案など、マーケティング活動を積極的に展開してきた。主要な外国クルーズ船社が就航し、中型船のカジュアルクルーズ、中型船のプレミアムクルーズを中心に寄港回数を増加させてきた。また、プレミアムクルーズならびにラグジュアリークルーズにおいては、その寄港回数が特定の地方 ...

Emerging applications of large language models in ecology and conservation science
Conservation Biology, EarlyView.Abstract Large language models (LLMs) mark a major development in artificial intelligence, with potentially transformative implications for ecology and conservation science. Built on advanced deep‐learning architectures, these models can support a wide range of tasks. We reviewed emerging applications of LLMs, drawing on the wider scientific literature

Shiyou jixie, 2015 针对钻井过程中循环钻井液流量控制不准确，造成螺杆钻具旁通阀总成无法开启闭合，阀心密封件失效刺漏等问题，通过φ244 mm等壁厚螺杆钻具旁通阀理论计算和循环试验，验证旁通阀工作可靠性。测得φ244 mm等壁厚螺杆钻具旁通阀关闭流量和开启流量；测得不同流量下旁通阀压降，确定阀心实际流量系数。分析结果表明，φ244 mm等壁厚螺杆钻具旁通阀在不同流量下产生的压差与循环试验获得压差十分接近，并且旁通阀在一定流量下均能实现阀心顺利打开和关闭。当流量由大变小时，阀心打开流量为20.20～14.60 L/s ...
