Soil water oxygen and hydrogen isotopes, Toolik Lake, Alaska, 2016
In this study we examine the ecophysiological consequences of different snow depth regimes in moist acidic tundra in the Alaskan Arctic, with a particular focus on the role of snowmelt water in plant ecophysiological processes. We paired regular measurements of leaf-level performance and tissue chem...
