火灾下的北极苔原生态系统——气候变化下的生态系统替代状态?
预计气候变化将导致北极冻土带生态系统的组成、结构和功能发生变化。冻土带火灾发生频率和严重程度的增加有可能催化植被转变,产生深远的地方、区域和全球后果。我们认为,火灾后苔原的恢复,加上气候变化,可能不一定会导致火灾前的条件。我们的假设基于调查和文献,提出了两种气候火灾驱动的轨迹。一条轨迹导致低火灾频率下木本植被增加;另一个结果是在高频率下草优势。未来的研究应解决与火灾有关的冻土带生态系统可能发生变化的不确定性,使用的方法应涵盖比以前更大的时间和空间尺度。更多的案例研究,特别是在代表性不足的区域和生态系统类型,对于扩大预测和潜在火灾管理战略的经验基础至关重要。合成。我们的综述综合了目前关于北极冻土带生态系统火灾后植被轨迹的知识,强调了潜在的转变和替代生态系统状态及其影响。我们讨论了在定义和预测这些轨迹以及未来方向方面的挑战。

期刊介绍: Journal of Ecology publishes original research papers on all aspects of the ecology of plants (including algae), in both aquatic and terrestrial ecosystems. We do not publish papers concerned solely with cultivated plants and agricultural ecosystems. Studies of plant communities, populations or individual species are accepted, as well as studies of the interactions between plants and animals, fungi or bacteria, providing they focus on the ecology of the plants. We aim to bring important work using any ecological approach (including molecular techniques) to a wide international audience and therefore only publish papers with strong and ecological messages that advance our understanding of ecological principles.
