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.

本研究在色季拉山东坡分别对雀形目鸟类、啮齿类以及蚁类开展了野外调查。雀形目鸟类的物种组成数据采集自17条样线（海拔800米至2300米）的4至10次野外观测，观测时段为2018/2019年6月至2020年6月。啮齿类野外调查包含铗捕法与野外观测两种方式。2014年，我们在9个样点开展了铗捕调查，分别在湿季早期（3月至7月）与湿季晚期（7月至9月）各进行1次，共2次调查。此外我们还开展了3次配套野外观测，其中前2次以铗捕法完成，第3次观测于2018年8月进行。2009年7月至8月，我们在11个样点采集了蚁类标本（包含3个未鉴定物种）。由于在海拔4548米的最高样点未发现蚁类，故判定该海拔区域无蚁类分布。
