File List Kelt_et_al_Species_and_Pools.txt (MD5: b72cfc3fbf2b1062da57cba4c871368e) Description Kelt_et_al_Species_and_Pools.txt is a tab-delimited text file. This file contains the complete raw data used in macroecological assessment of potentially equivalent small mammal species at 401 local sites in North America (201 sites), South America (103 sites), and the Gobi Desert of Central Asia (97sites). Sites in the Gobi Desert are separated to 3 distinct regions, and as such are distinguished as Gobi-1, Gobi-2, and Gobi-3. Column definitions: Region = Geographic region - Gobi (1, 2, or 3), North America, South America. SiteNum = Reference to site number, numbered separately by Region. Species_Recorded = 6-letter codes for species recorded at the focal site. Enclosed in round brackets () for ease of review. 999 = no species recorded. Species abbreviations are in Appendix A. Species_Pool = 6-letter codes for species in the species pool for the focal site. Enclosed in round brackets () for ease of review. Species abbreviations are in Appendix A.

文件描述：Kelt_et_al_Species_and_Pools.txt为制表符分隔的文本文件，包含用于北美（201个样点）、南美（103个样点）与中亚戈壁沙漠（97个样点）共计401个样点处潜在等价小型哺乳动物物种宏观生态学评估的完整原始数据。戈壁沙漠的样点被划分为3个独立区域，据此分别以Gobi-1、Gobi-2、Gobi-3予以区分。
列定义：
区域（Region）：地理区域，可取值为戈壁（1、2或3）、北美、南美。
样点编号（SiteNum）：样点编号参照，按地理区域单独编号。
物种记录（Species_Recorded）：目标样点中已记录物种的6位字母代码，以圆括号()括起以方便审阅；未记录任何物种时填999，物种缩写详见附录A。
物种种库（Species_Pool）：目标样点对应物种种库的6位字母代码，以圆括号()括起以方便审阅，物种缩写详见附录A。
