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 ...

Emerging applications of large language models in ecology and conservation science
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

Habitat and spatial trends of U.K. wintering waterbird populations over 50 years
Abstract The United Kingdom is an important wintering ground for millions of waterbirds. Most U.K. wintering waterbird populations increased between 1970 and the mid‐1990s, but declined thereafter. We examined U.K. population indices in 46 wintering waterbird species in two 25‐year periods, 1970–1994 and 1995–2019, to identify which waterbird groups ...

Changes in the transformative potential of action proposals in Finnish Red Lists from 1986 to 2019
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.

Uncovering correlates of decline and critical refuges for a threatened terrestrial mammal
Abstract Globally, the geographic ranges of numerous species are contracting. Identifying spatiotemporal patterns of threat impact can illuminate why species decline in some parts of their range but persist in others. We developed a correlative approach to identify species’ response thresholds and locate ecological refuge areas associated with ...

接地模拟试验是实现接地网参数预测与接地特性分析的基本方法。一些接地材料如柔性石墨复合接地材料、离子接地体以及接地模块等在进行接地模拟试验时,其部分相似项并不能按照相似条件进行缩比,使得接地网原型的预测误差较大。针对此问题,笔者首先阐述了接地模拟试验的畸变相似模型,分析接地模拟试验中畸变相似项的来源,然后提出畸变系数与畸变项敏感度的概念。最后通过仿真实例和实际接地模拟试验,分析不同土壤电阻率与模型相似比条件下,接地模拟试验对接地体直径畸变项与接地体电阻率畸变项的敏感度 ...

本发明涉及一种联合变换相关像移测量方法,该方法包括:1)在构造参考图像fr(x,y)和被测图像ft(x,y)时在两幅图像之间引入一个固定的错位量a;2)参考图像和被测图像按照像元强度值或灰度值对应相加,形成相关输入图像i(x,y);3)进行傅里叶计算,并对计算结果模的平方进行傅里叶逆变换后得到其相关输出;4)对互相关峰位置进行检测和计算,并对计算结果扣除固定错位量a得到两幅图像间的实际错位信息。本发明提供了一种在不影响测量性能的基础上可有效降低联合变换相关方法的计算量 ...

How identity bias affects perceptions of conservation messages on social media
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.

500 kV罗平站主变加装中性点限流电抗器电磁暂态研究及设备选型
随着电网的发展,部分自耦变压器中压侧电抗常接近于零,导致变压器220 kV侧发生近区单相或两相接地时,故障穿越电流已接近甚至超过变压器可承受短路电流的极限值,为限制罗平站220 kV单相或两相短路电流水平、改善主变运行环境,拟在主变中性点加装限流电抗器。采用最新EMTPE程序,通过对主变接入限流电抗后短路电流水平、过电压及绝缘配合等电磁暂态特性研究,提出了500 kV罗平站主变中性点限流电抗器阻抗选取原则及限流效果、工频及操作过电压水平、流经主变中性点电抗器的工频稳态及暂态电流水平 ...
