Magnificence in motion : climate and forest composition in Glacier National Park
MetadataShow full item record
Worldwide climate is changing, resulting in inevitable shifts in ecosystems. Climate directly influences forest composition through effects on mortality, recruitment, and growth. Furthermore, disturbance can short-circuit the process of gradual species overturn in response to climate change. After a disturbance, current climate conditions may favor the establishment of species that were not historically dominant, accelerating ecosystem shifts. Whereas mature trees are generally resistant to minor environmental fluctuations, regeneration niches are often extremely sensitive to climate. While ...
