geneflow_landscape_variables

The table contains landscape variables measured within the corridors between the study populations of Lychnis flos-cuculi in Oberaargau region, Switzerland. The corridors had different widths, which have been indicated in variable names: 50, 100, 300, 500 and 1000 meters. Columns include the proportion of the following landscape variables measured within corridors: forests (indicated as "forest" in the column name), settlements ("settlement"), the verges of ditches, streams and rivers ("water") and agricultural land ("agri"). Landscape variables were measured using VECTOR25 data by Swisstopo. In addition to landscape variables, the table includes cumulative elevation change between the study populations (in meters) as well as Euclidean distance between populations (in meters). The table also includes the measure of gene flow used in the study - genetic differentiation Fst.本数据集表格涵盖瑞士奥伯阿尔高（Oberaargau）区域内剪秋萝（Lychnis flos-cuculi）研究种群间廊道内测得的景观变量。这些廊道具有不同宽度，变量名中已标注对应宽度：50、100、300、500及1000米。表格列包含以下景观变量在廊道内的占比：森林（列名中以"forest"标识）、定居点（列名中为"settlement"）、沟渠、溪流与河岸边缘（列名中为"water"）以及农用地（列名中为"agri"）。上述景观变量通过Swisstopo的VECTOR25数据测得。除景观变量外，表格还纳入研究种群间的累积海拔变化（单位：米）与种群间的欧氏距离（单位：米）。此外，表格还包含本研究使用的基因流测度指标——遗传分化系数Fst。
