阿拉斯加内陆北方森林火灾严重程度的增加正在将森林树冠成分从黑云杉(Picea Mariana)转移到落叶树种，包括颤杨(Pillius Tremuloides)和阿拉斯加纸桦(Betula New Alaskana)。由于落叶乔木比黑云杉更不易燃，落叶林的主要干扰机制可能会从火灾转移到林隙干扰。在这项研究中，我们量化了阿拉斯加内陆地区八个成熟(62-119年)落叶林分的林隙特征和植被。冠层间隙一般较小(真实林隙面积
Increased fire severity in boreal forests of Interior Alaska is shifting forest canopy composition from black spruce (Picea mariana) to deciduous species, including trembling aspen (Populus tremuloides) and Alaska paper birch (Betula neoalaskana). Because deciduous trees are less flammable than black spruce, the dominant disturbance regime in deciduous forests could move away from fire to one of gap disturbances. In this study, we quantified forest gap characteristics and vegetation within eight mature (62-119-yr-old) deciduous stands in Interior Alaska. Canopy gaps were generally small (true gap area
