Springtails from Finse

This study was performed at the southwest-exposed slope of Mt. Sanddalsnuten, in Southern Norway (60° 36' 55'' N, 7° 31' 8'' E) at approximately 1500 m a.s.l. The site has calcareous phyllite bedrock and is dominated by Dryas octopetala heath. The area is moderately grazed by domestic sheep and wild reindeer (Rangifer tarandus Linneus 1758). Lemming (Lemmus lemmus Linneus 1758) populations in Finse peaked in 2014, while other rodent species showed low abundances throughout the entire duration of the study. Ten blocks of four 1 × 1 m plots were randomly established in the Dryas heath. Within each plot, two permanent 60 × 30 cm vegetation-sampling subplots were established, separated by a 10 cm wide row. In 2004 and 2016, we sampled soil micro-arthropods in the row between the subplots.

本研究于挪威南部桑兹纳滕山（Mt. Sanddalsnuten）西南坡开展，地理坐标为60°36′55″N、7°31′8″E，海拔约1500米（a.s.l.）。该样地基岩为钙质千枚岩，原生植被以仙女木（Dryas octopetala）灌丛为主。区域内受家养绵羊与野生驯鹿（Rangifer tarandus Linneus 1758）的中度放牧。芬瑟（Finse）地区的旅鼠（Lemmus lemmus Linneus 1758）种群在2014年达到种群峰值，其余啮齿类物种在整个研究周期内种群丰度均处于较低水平。研究人员在仙女木灌丛中随机布设10个样区，每个样区包含4块1×1米的样方。每个样方内设置2个永久植被采样小样方，尺寸为60×30厘米，二者以10厘米宽的分隔带相隔。2004年与2016年，研究人员在该分隔带中采集了土壤微型节肢动物。
