Assessing differences among elasmobranch nurseries to aid conservation based on a genomics framework
Conservation Biology, EarlyView.Abstract Elasmobranch nurseries often differ in environmental conditions, demographics, and use patterns. These differences affect the distribution of genetic variation among nurseries. However, conservation and management strategies often fail to account for such differences because they are difficult to characterize.

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

Dianci bileiqi对电气设备地震动响应分析应用较多的主要有两种方法——振型分解反应谱法和动力时程法，其中某些关键动力参数的取值在电气设备抗震相关规范中并没有具体规定，实际分析时往往凭个人经验，致使分析结果因人而异、不尽准确。为了在计算分析阶段通过对关键动力参数准确取值，尽可能真实获取结构动力响应，本研究以特高压支柱式电气设备颇具代表性的两种材质的结构本体及加装减隔震装置后的结构为分析对象，在非线性时程分析方面，通过对动力时程法主要参数：振型参与阶数、地震波及峰值加速度的影响对比分析 ...

Jianzhu Gangjiegou Jinzhan, 2016 为了揭示某体育馆屋盖马鞍形钢结构体系的新颖独特,将整体屋盖划分为外围结构和内场结构进行受力分析,介绍了节点形式,总结了结构的各项计算参数。弹性地震分析表明,结构的极限状态分析结果和整体受力性能满足设计要求。针对抗侧斜柱进行了几何非线性稳定分析,计算结果表明未出现失稳现象。通对整体结构的抗连续性倒塌分析,判断出重要构件并借助敏感性分析将构件的重要性进行了排序,并针对抗侧斜柱采用了简化分析方法,最终分析结果表明,杆件失效后整体结构不会发生垮塌。证明了结构方案的安全性和合理性。

Insights for conservation from the Ecological Knowledge Games project
Conservation Biology, EarlyView.Abstract Environmental conservation research requires robust methods for collecting large‐scale behavioral data and engaging diverse stakeholders in decision‐making processes. We (Y.P., A.B.D., and N.B.) created EcoKnowGames (Ecological Knowledge Games), a transdisciplinary project that develops knowledge games for conservation science and data ...
