Protocol_recording_supranivean_activity_vertebrates

Protocol for recording supranivean activity of vertebrates, used in 2006–2015. During the period of annual snowpack measurements in Komagdalen, Vestre Jakobselv and Ifjordfjellet in March, track frequencies of vertebrates (mammals and ptarmigans) were recorded along transects covering meadows with willow shrubs and heaths. Identified vertebrate tracks were marked either as crossing tracks or snow holes, and registered with GPS coordinates.

本规程为2006至2015年间使用的雪上层（supranivean）脊椎动物活动记录方案。每年3月，在科马格达伦（Komagdalen）、韦斯特·亚科布塞尔夫（Vestre Jakobselv）与伊夫约德菲耶特（Ifjordfjellet）开展年度积雪测量期间，研究人员沿覆盖柳灌丛草甸与石楠荒原的样带，记录脊椎动物（哺乳类与雷鸟）的足迹频次。已识别的脊椎动物足迹被标记为通行轨迹或雪洞，并同步记录其GPS坐标。
