野生动物学报, 2012 2010～2011年,在吉林向海国家级自然保护区采用固定半径样点法对春秋两季的鸟类多样性进行了调查,共记录到鸟类114种22 111只次,隶属于14目34科。应用逐步向后回归模型探测春、秋两季不同景观类型与鸟类香农-维纳指数、均匀性指数和物种丰富度指数之间的关系。结果表明,湿地鸟类群落在季节间发生种类结构的显著变化,不同景观类型对不同多样性指数的影响不同,农田会显著减少湿地鸟类多样性,水域和沼泽对香农-维纳多样性有正效应,但是对均匀性和物种丰富度有负效应,距公路较近会减少鸟类春季的均匀性和香农 ...

Genetic origins and climate‐induced erosion in economically important Asian walnuts
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract The global climate is undergoing unprecedented changes, posing significant threats to species persistence. However, the spatiotemporal impacts on genetic diversity remain poorly understood, hindering species conservation and management. Walnuts, generally referred to as Juglans regia and J. sigillata, are economically vital in Asia, but little

Contribution of microcosm experiments to conservation science
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract Microcosms, or miniature experimental systems, have been used to develop models and theories in ecology. However, their contribution to conservation science is unclear. We explored the application, design, and impact of microcosms in conservation science from 469 systematically identified articles published from 1986 to 2023.

Conservation Biology, Volume 40, Issue 1, February 2026.Abstract As biocultural approaches to conservation gain traction (e.g., through international commitments to Indigenous Peoples and local communities) and external conservation actors increasingly seek to engage with on‐the‐ground holders of biocultural diversity, improved understanding is needed of what biocultural diversity means.

贝叶斯联合模型与中国洞穴鱼类分化时间的估算(鲤科:金线鲃属) [PDF]
, 2008 金线鲃属分布于中国云贵高原及周边地区,包括10多种适应于洞穴生活、具有不同程度眼睛和色素退化的典型洞穴鱼类.迄今为止,金线鲃属的系统发育关系还存在很大争议.我们获得了34种金线鲃属鱼类及外类群的细胞色素b和ND4基因序列,用贝叶斯联合模型分析数据,重建了金线鲃属的系统发育关系;并用松散分子钟估算了本属及内部分支的起源时间.金线鲃属的单系性得到强烈的支持,本属可分为6个分支.此外,本研究结果还支持洞穴物种的多系起源假说以及季氏金线鲃(Sinocyclocheilus jii)的基部位置 ...

Detecting mass mortality events in wildlife populations
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract Reports in the literature of mass mortality events (MMEs) involving diverse animal taxa are increasing. Yet, many likely go unobserved due to imperfect detection and infrequent sampling. MMEs involving small, cryptic species, for instance, can be difficult to detect even during the event, and degradation and scavenging of carcasses can make ...
