Leaf nitrogen and digestibility for tall shrubs, dwarf shrubs, and sedges within ambient, deep, and shallow snow zones of the moist acidic tundra snow fence at Toolik Lake, Alaska, 2017-2018
This is a data set contribution from "Nutritional Landscapes of Arctic Caribou: Observations, Experiments, and Models Provide Process-Level Understanding of Forage Traits and Trajectories". These data are part of a long-term snow fence experiment that has created areas of deep snow and sha...
