In a recent issue of Journal of Plant Ecology,Liang et al.(2013)use meta-analytical techniques to analyze the leaf carbon exchanges responses to experimental warming and,in part,observe that leaf dark respiration,but not photosynthesis,acclimates to the warming *** authors should be commended for putting together and analyzing such a large data *** of the results provide fine syntheses for understanding leaf carbon exchange responses to ***,the acclimation analyses are,in my opinion,flawed and are not appropriate for supporting their results.

有壳虫(Testacea)是一类常见的自由生活的原生动物,在生态系统物质循环和能量流动中发挥重要作用。作者在分析地球三极(北极、南极、西藏)地区有壳虫种类名录(62属315种)基础上,对有壳虫区系特征、地理分布及其影响因素进行了研究。结果显示,北极地区已记录25科51属232种;南极地区20科30属131种;西藏地区22科42属173种。三个地区物种丰富度最高的属均为砂壳虫属(Difflugia)、匣壳虫属(Centropyxis)、梨壳虫属(Nebela)、鳞壳虫属(Euglypha)和表壳虫属(Arcella);5个属的种数分别占北极、南极、西藏总种数的51.3%、63.4%和60.1%。此外,3个地区共有种数是73(23.2%),共有属数是24(38.7%);仅在1个地区记录的种数是167种(53.0%)。在三极地区40个亚区域,苔藓鳞盖虫(Assulina muscorum)和旋匣壳虫(Centropyxis aerophila)的分布最广泛,出现频率均高达90%。聚类分析显示,三个地区种水平相似性系数为51.3-56.3%,属于中等相似,北极和西藏相似系数最大。相似性分析表明,虽然有壳虫具有较强的长距离被动扩散能力,但是一些大于100μm的种类不是全球性分布。有壳虫的地理分布格局与个体大小、生境类型、地质历史事件等密切相关,分析结果受物种鉴定标准、样品数量、空间尺度大小等因素影响。
