调查世界屋脊高山物种向上扩展分布范围的潜力。
高山地区气候变暖的速度快于全球平均水平。为了躲避不断升高的气温,高山物种的分布可能会向上转移,从而威胁到适应寒冷环境的原生植物。然而,人们对高山物种在现有分布区以外的高海拔地区,尤其是喜马拉雅山脉最高的山区,能否成功萌发和建立幼苗却知之甚少。我们在尼泊尔东北部昆布山谷(Khumbu Valley)的自然生长地(GS)、高海拔地区(HS;海拔 5000 米)和高海拔地区生长地的土壤(HS-S)中选择了四种生长在海拔 4000 米左右的本地高山植物播种。我们对连续两年的出苗和成苗情况进行了监测。不同物种的出苗和成苗情况各不相同。GS 和 HS 的出苗情况相似,而 HS-S 的出苗情况有所改善。高海拔地区的植株成活率较低,除一个物种外,其他所有物种在冬季后的死亡率都很高。在珠峰地区的高海拔地区,低海拔植物有可能出苗,这表明物种的分布范围可能会向上转移。不过,虽然并非所有物种都能在高海拔地区成功成活,但可能会受到土壤和冬季高死亡率的限制。气候变暖可能会导致喜马拉雅山脉的一些植物物种向上迁移,从而改变高山地区的群落组成。

期刊介绍: Plant Biology is an international journal of broad scope bringing together the different subdisciplines, such as physiology, molecular biology, cell biology, development, genetics, systematics, ecology, evolution, ecophysiology, plant-microbe interactions, and mycology. Plant Biology publishes original problem-oriented full-length research papers, short research papers, and review articles. Discussion of hot topics and provocative opinion articles are published under the heading Acute Views. From a multidisciplinary perspective, Plant Biology will provide a platform for publication, information and debate, encompassing all areas which fall within the scope of plant science.
