为探究生境面积大小对Janzen-Connell (JC)效应中密度和距离制约的影响以及驱动机制,为生境破碎化背景下植物多样性的维持机制提供科学依据,本研究在Web of Science数据库中收集并筛选出1970-2019年全球50个森林地点作为数据基础,采用荟萃分析法分析密度和距离制约实验中不同类型驱动者的效应值大小,并采用分段回归和非分段回归分别模拟分析密度和距离制约效应值与生境面积的关系。结果表明,在67项研究的161项实验中,病原菌和无脊椎动物的效应值大小在距离制约实验中显著小于0(存在JC效应),而在密度制约实验中不显著。相反地,脊椎动物的效应值大小仅在密度制约实验中显著小于0。虽然只有距离制约效应值随生境面积的减少呈先增大后减小的趋势,但密度制约趋势线的拟合转折点在距离制约之前,表明生境面积减少会先影响密度制约。本研究阐明了密度和距离制约的主要驱动者分别是密度型驱动者(脊椎动物)和距离型驱动者(病原菌和无脊椎动物),而密度制约比距离制约对生境面积的减少有更为敏感的表现,可能是这两种驱动者对生境面积的需求不同所导致的。因此,在不同生境面积的片段中关注不同类型的驱动者有利于生物多样性的维持。

Dear Editors, The properties of mixed-valence manganites are sensmve to the synthesis conditions [ 1 ]. For oxide films grown by pulsed laser deposition （PLD）, the physical properties are affected obviously by the growth oxygen pressure and annealing treat- ment [2-5]. Using the PLD method, manganite oxides are usually grown at different oxygen pressures to investigate the effects of oxygen content on their properties. However,
