Informal supply chains of wild meat from rural Amazonia and food security in an urban center
Conservation Biology, EarlyView.Abstract Iquitos, the most populated city in the Peruvian Amazon, is a hub in the regional supply chain of wild meat and supplies urban consumers. Studies on wild meat consumption have focused primarily on markets, limiting the scope of species considered to those that are economically valuable and potential inferences from those data.

He jishu编码孔径成像广泛应用于低能量（<0.2 MeV）伽马成像领域，其在中高能段（0.2~5 MeV）的应用也在得到逐步拓展。为解决中高能伽马成像中串扰光斑、内散射增强所导致的成像性能恶化的问题，提出了基于推测首次反应位置的降噪方法。通过使用掺铈钆铝镓石榴石晶体（Cerium-doped Gadolinium Aluminum Gallium Garnet，GAGG：Ce）与硅光电倍增管（Silicon Photon Multiplier，SiPM）阵列耦合，并使用A5202采集模块读出 ...

面向工程应用的先进绝热压缩空气储能模型及先进㶲分析 [PDF]
全球能源互联网先进绝热压缩空气储能（advanced adiabatic compressed air energy storage system，AA-CAES）仿真建模及分析是其工程实践的基础。然而，目前模型一般基于理想工况建立，分析结果与实际工况相偏差较大，无法指导工程应用。为此，在传统热力学模型基础上，考虑了空气流动阻力损失和能量转换设备损耗等因素，建立了面向工程应用的AA-CAES模型并以200 MW盐穴AA-CAES系统为例进行了分析。同时，对系统效率分析方法进行改进并对其进行了先进分析。结果表明 ...

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
