Abstract:
This study investigated the effects of field manipulations of winter precipitation and summer temperature on species performance, community structure, and ecosystem C and N dynamics. Parameters include ground temperatures at the surface and 15 cm along a gradient of snow depths, snow depth, soil temperatures at 10 cm intervals at several sites in drifts and unimpacted vegetation sites, and active layer thickness. Temperature profiles were monitored continuously. Snow depths were monitored in a grid behind snow fences and in a 1 x 1 km grid surrounding the fence sites. Active layer was monitored at the end of the season. These data are part of the International Tundra Experiment (ITEX) network.
