The effects of a half century of warming and fire exclusion on montane forests of the Klamath Mountains, California, USA

Jules, Melissa H. DeSiervo, Matthew J. Reilly, Drew S. Bost, and Ramona J. Butz Climate warming and altered disturbance regimes are changing forest composition and structure worldwide. Given that species often exhibit individualistic responses to change, making predictions about the cumulative effects of multiple stressors across environmental gradients is challenging, especially in diverse communities. For example, warming temperatures are predicted to drive species upslope, while fire exclusion promotes expansion of species at lower elevations where fire was historically frequent. We resampled 148 vegetation plots to assess 46-years (1969 to 2015) of species and community-level response to warming and fire exclusion in a topographically complex landscape in the Klamath Mountains, Californi...本数据集所用稿件为《美国加利福尼亚州克拉马斯山脉山地森林半个世纪以来的气候变暖与火抑制效应》（Effects of a half century of warming and fire exclusion on montane forests of the Klamath Mountains, California, USA），相关文件即该稿件依托的原始数据。 稿件作者：埃里克·S·朱尔斯（Erik S.
