Conservation Biology, EarlyView.Abstract Reversing ongoing biodiversity loss requires effectively managing anthropogenic threats. Although conservation actions can mitigate these threats, prioritizing and targeting such actions remain challenging because species respond differently depending on the nature of the threats and their biological traits.

Comprehensive and representative conservation planning for biodiversity of ice‐free Antarctica
Conservation Biology, EarlyView.Abstract Antarctica is designated as a natural reserve devoted to peace and science, with Antarctic Specially Protected Areas (ASPAs) serving as the primary instrument for area‐based biodiversity protection. However, the existing ASPA network lacks the comprehensiveness and representativeness required under Annex V, Article 3(2), of the Madrid Protocol.

TCD与低剂量双源性CTA对海南地区原居住居民后循环缺血及椎基底动脉易损斑块分布规律的研究
Zhongguo shiyan zhenduanxue, 2016 目的探讨海南地区原住居民后循环血管缺血情况及椎基底易损斑块分布规律。方法 2015年1月—2015年8月期间对海南地区原住居民及内地迁居人群进行经颅多普勒(TCD)及低剂量双源CT血管造影(CTA)头颈血管筛查,共800例海南地区原住居民及500例内地迁居居民作为研究对象纳入研究。结果海南地区原住居民与内地迁居居民血管的狭窄部位多在椎基底动脉,经统计学检验发现二者血管狭窄部位构成有统计学差异(χ2=13.203,P=0.001)。海南地区原住居民L-VA、BA的Vs值,R-PCA、BA的Vm值,R ...

Conservation Biology, EarlyView.Abstract The sustainability of area‐based conservation initiatives depends on their value to society. Conservation often focuses inside protected areas, but the impacts of protected areas beyond their boundaries (spillovers) are critical for their social license.

Methodology to identify ecologically matching areas and its applications in conservation planning
Conservation Biology, EarlyView.Abstract Identifying ecologically matching areas is both challenging and critical for understanding spatial patterns of biodiversity and advancing conservation planning. However, existing approaches often lack spatial flexibility, overlook shape and size constraints, or rely on limited environmental parameters, reducing their effectiveness in real ...

Conservation Biology, EarlyView.Abstract Robust estimates of the magnitude of protected species bycatch are essential for effective fisheries management and marine conservation. Existing bycatch estimation methods typically struggle to accurately and precisely estimate the bycatch of rare species as a result of the statistical assumptions necessary to overcome infrequent encounters ...

智慧农业, 2023 目的/意义人工智能（Artificial Intelligence，AI）技术已在学术和工程应用领域掀起了研究高潮，在地球物理参数和农业气象遥感参数反演方面也表现出了强大的应用潜力。目前大部分AI技术在地学和农学的应用还是“黑箱”，没有物理意义或缺乏可解释性及通用性。为了促进AI在地学和农学的应用和培养交叉学科的人才，本研究提出基于AI耦合物理和统计方法的地球物理参数反演范式理论。方法首先基于物理能量平衡方程进行物理逻辑推理，从理论上构造反演方程组，然后基于物理推导构建泛化的统计方法 ...

Conservation Biology, EarlyView.Abstract Global farmland biodiversity is declining rapidly, threatening both natural ecosystems and agricultural production. Although agri‐environmental schemes incentivize farmers to adopt environmentally friendly measures, the spatial mismatch between their local implementation and the landscape‐scale habitat requirements of farmland species has been
