Data from: More is less: net gain in species richness, but biotic homogenization over 140 years

Data - More is Less - Nielsen et al - Ecol Lett 2019Data on 1958 plant species from Denmark. Historical data (1857 to 1883) and present data (2012) from the same regions. Data contains two data-files, one with presence-absence data from 14 Danish regions and one with regional abundance data from 10 Danish regions (for calculations and precausions relating to abundance, please see App. 2 of publication). The presence absence data file also includes data on whether species are native or exotic to Denmark.Nielsenetal_2019.xlsx

数据集：More is Less —— Nielsen 等，Ecol Lett，2019。本数据集收录丹麦境内1958种植物的相关数据，涵盖同一区域的历史（1857年至1883年）与当代（2012年）观测记录。本数据集包含两份数据文件：其一为丹麦14个区域的物种出现-缺失（presence-absence）数据，其二为丹麦10个区域的区域尺度物种多度（abundance）数据；有关物种多度的计算方法及相关注意事项，请参见该发表论文的附录2。此外，该出现-缺失数据文件还收录了各物种在丹麦属于本土还是外来物种的相关信息。数据集文件名为：Nielsenetal_2019.xlsx
