1物种分布模型在古生物学研究中的应用显示文摘物种分布模型(Species distribution models,SDMs)是基于物种的生态位要求,通过将物种已知的分布数据和对应地区的环境数据联系起来,以预测该物种在不同时间和空间下的地理分布的一种数学工具。它为地史时期生物地理分布的重建、生物生态特征的分析及生物与地球环境协同演化研究等提供了一种新的途径。此方法具有研究精度高、预测效果好及应用广泛等优点,尤其适合开展高精度的古生物地理、古生态及生物宏演化等相关研究。文章着重介绍物种分布模型的基本原理及建模流程,在此基础上以笔石种Tang yagraptus typicus Mu作为建模实例进一步说明物种分布建模的详细步骤,最后概述此方法在古生物研究中的适用性及存在的问题。张琳娜 樊隽轩 Melchin M J 陈清 Wu Shuang-ye Goldman D Mitchell C M Sheets H D 2013古生物学报2013,52,2:6
2全球经济失衡展望——依实证和专题研究的视角显示文摘本文证实了自金融危机爆发以来全球经常账户失衡程度的显著改善。具体来说,美国的经常账户赤字占GDP的比例从6%的高位下降了一半,到了3%;中国的经常账户盈余也有了显著下降。对上述两国失衡的降低,以及更具一般性的全球失衡程度的降低,我们接着考量了其仅仅是由于失衡被金融危机所打断而引起的暂时性偏移,还是长期性的调整。Nathan Sheets Elina Ribakova Robert A Sockin 2012金融发展评论2012,,5:2
