Assessing and strengthening community‐based coastal governance
Conservation Biology, EarlyView.Abstract Community‐based coastal governance is essential for biodiversity conservation and sustainable livelihoods, yet many communities continue to face significant challenges in establishing and sustaining effective governance systems. We sought to improve understanding of the current status of community‐based coastal governance across five countries

Modeling seed germination data to meet biodiversity conservation needs in the Mediterranean
Conservation Biology, EarlyView.Workflow to assess the availability and quality of germination data and assign species' thermal risk in the Mediterranean. (a) Assessment of data availability, including the phylogenetic distribution of the number of records (i.e. available germination data); (b) data quality assessment; and (c) assignment of climate risk categories for species that ...

Shuitu Baochi Xuebao, 2000 根据我国北方地区历年油松飞播调查资料和对典型播区的调查，阐明了油松飞播的地理分布和效果；同时运用统计分析和模糊数学分析等方法，对影响油松飞播成效的主要因子作了系统的宏观分析，得出年均降水量和年均气温是影响飞播效果的主要因子。在此基础上，对北方地区油松飞播造林进行了适宜性分区，分区结果将油松飞播划分为３个区，即造林适宜区，造林次适宜区和造在适宜区，对指导今后油松飞播生产具有重要意义。

International Journal of Applied Linguistics, EarlyView.ABSTRACT Many existing rubrics for L2 argumentative writing prioritize form‐based linguistic accuracy and complexity while insufficiently addressing substantive argumentative rigor and effectiveness. This limitation is further complicated by cross‐cultural variation in rhetorical conventions and educational practices, which challenge the direct ...

基于线粒体DNA Cyt b西伯利亚狍种群分子系统地理学研究
野生动物学报, 2020 世界上对西伯利亚狍的分类和系统地理格局划分意见不一,目前普遍认为将西伯利亚狍分为Capreolus pygargus pygargus、Capreolus pygargus tianschanicus、Capreolus pygargus melanotis 3个亚种。本研究对中国小兴安岭地区的西伯利亚狍(40份样品)的线粒体DNA Cyt b部分序列进行分析,共扩增出32条序列,获得9个单倍型。并利用从GenBank下载的来自世界各地的40条西伯利亚狍的线粒体DNA Cyt ...

Regional News, Regional Bias? Evidence From Media Discourses and Welfare Decisions in Germany
Policy Studies Journal, EarlyView.ABSTRACT How do media representations of immigrants shape their treatment by street‐level bureaucrats? Despite a uniform federal legal framework, decision‐making varies substantially across local welfare offices. Though prior research links national news reporting and policy implementation, little is known about how regional variation in news reporting

单变量多重定态转变体系中热传导-化学反应偶合诱发的温度-浓度振荡
四川大学学报. 自然科学版, 2003 以Schl¨ogl模型为样本,分析了该类非恒温均匀的单变量多定态转变体系中因传热 化学反应诱发的热动力学振荡.分别借助小寄生参数法与线性化稳定性分析法,具体讨论了产生温度 浓度振荡的阈值,并计算了参数空间中的振荡区,论证了两种分析方法出现振荡的参数空间重叠区,是该类二变量体系出现吻合一致的极限环振荡的充分必要条件.丰富了二变量体系出现极限环振荡的判据体系.
