Raw presence-absence community composition of passerines, rodents, and ants at eastern slope of Mt. Segrila

Along the eastern slope of Mt. Segrila, we performed field surveys for passerines, rodents, and ants, respectively. The compositional information of passerines was collected from 4-10 times’ field observations of 17 sampling transects (800 m-2,300 m) dating from June 2018/2019 to June 2020. Field survey on rodents included snap-trapping and field observations. Snap-trappings were conducted from nine sampling sites with two trapping surveys during early (March-July) and late (July-September) wet seasons in 2014. We also conducted three field observations as snap-trapping, of which the first and second were carried out as snap-trapping, and the third field observation was conducted in August 2018. We collected ant species (including three unidentified species) from 11 sampling sites during July-August 2009. As we found no ant in the highest sampling sites (4,548 m), they were judged absent there.

我们在色季拉山东坡分别针对雀形目鸟类、啮齿类与蚁类开展了野外调查。雀形目鸟类的组成信息采集自2018/2019年6月至2020年6月期间，对17条海拔800米至2300米的样带进行的4至10次野外观察。啮齿类的野外调查包含夹日法诱捕与野外观察两类：夹日法诱捕于2014年湿季早期（3月-7月）与晚期（7月-9月）在9个采样点各开展1次诱捕调查；此外我们还实施了3次野外观察，其中前2次采用夹日法诱捕，第3次野外观察于2018年8月完成。蚁类物种（包含3个未鉴定物种）的采集工作于2009年7月至8月在11个采样点开展。因在海拔最高的4548米采样点未发现蚁类，故判定该点无蚁类分布。
