Regional variability in the response of alpine treelines to climate change Jun 10, 2020 Davis, Emma L.; Brown, Robert; Daniels, Lori; Kavanagh, Trudy; Gedalof, Ze’ev, 2020, "Regional variability in the response of alpine treelines to climate change", https://doi.org/10.5683/SP2/CWJ7IO, Borealis, V1, UNF:6:UIGdq9uhZR7+26QdeLJ/IQ== [fileUNF] The distributions of many high-elevation tree species have shifted as a result of recent climate change; however, there is substantial variability in the movement of alpine treelines at local to regional scales. In this study, we derive records of tree growth and establishment fr...
