Abstract:
Inland waters are among the most threatened biodiversity hotspots. Ponds located in alpine areas are experiencing more rapid and dramatic water temperature increases than any other biome. Despite their prevalence, alpine ponds and their biodiversity responses to climate change have been poorly explored, reflecting their small size and difficult access. To understand the effects of climate change on alpine pond biodiversity, we performed a comprehensive literature review for papers published since 1955. Through analysis of their geographic distribution, environmental features, and biodiversity values, we identified which environmental factors related to climate change would have direct or indirect effects on alpine pond biodiversity. We then synthesized this information to produce a conceptual model of the effects of climate change on alpine pond biodiversity. Increased water temperature, reduced hydroperiod, and loss of connectivity between alpine ponds were the main drivers of biodiversity geographic distribution, leading to predictable changes in spatial patterns of biodiversity. We identified three major research gaps that, if addressed, can guide conservation and restoration strategies for alpine ponds biodiversity in an uncertain future.
摘要:
内陆水域是生物多样性威胁最大的热点地区之一。位于高山地区的池塘正在经历比任何其他生物群落更迅速和戏剧性的水温上升。尽管流行,高山池塘及其生物多样性对气候变化的反应一直没有得到充分的探索,反映了他们的小尺寸和难以接近。为了了解气候变化对高山池塘生物多样性的影响,我们对1955年以来发表的论文进行了全面的文献综述。通过对其地理分布的分析,环境特征,和生物多样性价值,我们确定了哪些与气候变化相关的环境因素会对高山池塘生物多样性产生直接或间接影响。然后,我们综合了这些信息,以建立气候变化对高山池塘生物多样性影响的概念模型。水温升高,减少的水期,高山池塘之间的连通性丧失是生物多样性地理分布的主要驱动因素,导致生物多样性空间格局的可预测变化。我们发现了三个主要的研究空白,如果解决了,可以在不确定的未来指导高山池塘生物多样性的保护和恢复策略。
