Abstract

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.

Methods

Within an approximate 2,500 m altitudinal range along the eastern slope of Mt. Segrila, we performed field surveys for these three animal groups. 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 (mean elevations: 2,000 m, 2,300 m, 2,450 m, 2,550 m, 2,650 m, 2,750 m, 2,850 m, 3,050 m, 3,350 m, 3,450 m, 3,550 m, 3,850 m, 4,050 m, 4,150 m, 4,250 m, 4,350 m and 4,500 m). The passerine dataset contained 116 species of 64 genera and 34 families. Field survey on rodents included snap-trapping and field observations. Snap-trappings were conducted from nine sampling sites (mean elevations: 2,000 m, 2,300 m, 2,600 m, 2,900 m, 3,200 m, 3,500 m, 3,800 m, 4,100 m and 4,400 m) 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. In total, we have collected 14 rodent species, in which two species (Sciurotamias davidianus and Marmota himalayana) were collected from field observations only. We collected 18 ant species (including three unidentified species) from 11 sampling sites (mean elevations: 2,000 m, 2,250 m, 2,500 m, 2,750 m, 3,000 m, 3,250 m, 3,500 m, 3,750 m, 4,000 m, 4,250 m, and 4,548 m) during July-August 2009. As we found no ant in the highest sampling sites (4,548 m), they were judged absent there.
