- The Global Extent and Determinants of Savanna and Forest as Alternative Biome States
[作者:Staver, AC; Archibald, S; Levin, SA,期刊:Science, 页码:230-232 , 文章类型: Article,,卷期:2011年334-6053]
- Theoretically, fire-tree cover feedbacks can maintain savanna and forest as alternative stable states. However, the global extent of fire-driven discontinuities in tree cover is unknown, especially accounting for seasona...
