Methods in Ecology and Evolution, Volume 17, Issue 4, Page 1143-1160, April 2026.Abstract DNA barcode‐based species identification has become pivotal in biodiversity research. Current barcoding‐based deep learning methods have advantages in species identification but exhibit significant limitations. By using COI barcoding alone, previous studies were unable to fully capture species identification features. Prior methods showed that

Elephant barrier behaviors in response to conflict mitigation fences
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Human–wildlife conflict is a major conservation issue, particularly in lower income countries, where it affects marginalized people and leads to the extirpation of threatened species. Managers increasingly use fences to reduce this conflict but lack evidence on the effectiveness of these barriers, especially on whether this reduces the number ...

裸露砒砂岩区坡面侵蚀过程中地表粗糙度与水力侵蚀特征参数的关系
Shuitu Baochi Xuebao, 2022 坡面地形起伏状况是影响土壤侵蚀状况的重要因素,深入了解地表粗糙度和产流产沙以及水动力参数之间的关系是研究坡面土壤侵蚀过程的基础。采用野外原位模拟冲刷试验,使用三维激光扫描仪结合ArcGIS提取地形因子参数,研究了裸露砒砂岩区坡面侵蚀过程中地表粗糙度与侵蚀特征参数的关系。结果表明:(1)冲刷强度的增大使得阻力特征参数逐渐降低,且随着冲刷时间的增加,弗劳德数也呈现降低趋势,其他水力学参数呈增大趋势 ...
