Small mammal mark-recapture data 2017-2023 (3 sites near Toolik Lake, Alaska) ...

We conducted mark-recapture surveys of small mammals in tussock tundra at three sites near Toolik Lake Alaska (AK) (68.6 North (N), 149.5 West (W), 760 meters (m) above sea level). In 2017, we established a mark-recapture grid at each of three sites (Imnavait (IM), Pipeline (PL), and South Toolik (S...

Description
Summary:We conducted mark-recapture surveys of small mammals in tussock tundra at three sites near Toolik Lake Alaska (AK) (68.6 North (N), 149.5 West (W), 760 meters (m) above sea level). In 2017, we established a mark-recapture grid at each of three sites (Imnavait (IM), Pipeline (PL), and South Toolik (ST)). Each grid consisted of 120 trap stations set in a 15 x 8 arrangement with 10 m spacing, and encompassed an area of 1.2 hectares (ha). Mark-recapture surveys were conducted twice during the summer season in early June and late August in 2017 - 2019 and then truncated to once a year in 2020 - 2023 due to COVID-19 access and quarantine policies. Also as a result of COVID-19 access policies, the Pipeline grid was not surveyed in 2020. A single Sherman live trap was set within one meter of each station, baited with a mixture of peanut butter and bird seed, and insulated with polyester batting. Grids were surveyed for four consecutive days with traps checked every six to eight hours. On occasion heavy rain ...
