Conservation Biology, Volume 40, Issue 1, February 2026.Abstract Exploring heat tolerance and acclimation capacity can provide an effective approach to evaluating species’ sensitivity to extremely high temperatures due to climate warming. Despite some work on amphibian and reptile thermophysiological adaptation, related questions remain. We reviewed the literature to provide a synthesis of worldwide data on

Shuitu Baochi Xuebao, 2019 针对盐渍化灌区土壤盐渍化问题，以河套灌区下游乌拉特灌域为研究区，通过野外实测与室内试验分析结合，采用统计学方法地质统计学原理分析表层土壤（0—20，20—40 cm）及深层土壤（40—100 cm）含水率与盐分（EC值）时空分布和变异规律，以及探求地下水埋深对土壤盐分的影响。结果表明：（1）除6月0—20 cm（9.779%）外，表层土壤含水率变异系数均在12.384%~19.667%，属于中等变异性，深层土壤含水率变异系数较小，在3.513%~9.757%，属于弱变异性）表层土壤盐分（EC值 ...

Test-Retest Reliability and Its Computation of Resting State Functional Magnetic Resonance Imaging [PDF]
, 2015 功能连接组(Functionalconnectomes)即人脑内部功能连接的全体。目前功能连接组指标已成为人脑功能研究中的重要参考依据。在人脑发育和疾病研究中出现了越来越多的方法用于关注脑功能的变化。由于具有不受任务设计限制的优势，因此静息态功能磁共振(rfMRI)成为人脑功能连接组学研究的主要方法之一。静息态功能磁共振图像的计算指标主要包括功能分化和功能整合两部分。鉴于开发具备高重复性的脑功能连接组学计算方法对研发基于脑成像的人脑功能影像学标记物重要性 ...

Shuitu Baochi Xuebao, 1996 利用自制的毛根拉力测定装置，首次对黄土高原１２种常见牧草０．１～１．０ｍｍ毛根生物力学特性进行了系统研究。结果表明，牧草毛根具有强大的抗拉能力。直径为０．１～０．２ｍｍ禾本科根系抗拉力达１．３７Ｎ，豆科０．７７Ｎ，菊科０．６９Ｎ。毛根抗拉力随直径增加而增大，递增率为禾本科＞豆科＞菊科。根龄对抗拉力的影响因种而异，菊科当年新根与老活根抗拉力无明显差异。研究发现豆科沙打旺和禾本科无芒雀麦应力—应变为对数函数关系，应变递增速度快，不符合胡克定律。其余牧草本构方程遵从胡克定律，但其弹性模量因种而异 ...
