Abstract

Sky islands are unique geologic formations, home to populations of organisms that have weathered climate change since the Pleistocene. Long-term isolation and climatic differences between sky islands and adjacent mountain chains result in natural laboratories well suited for examining the direct effects of climate change. Here, we review the global sky island literature to examine how taxa have responded to climate change. Results show lineage formation, reduced genetic variation, and trait evolution across taxa driven by genetic drift and natural selection. These effects continue today due to ongoing habitat reduction and steep selective gradients on sky islands relative to mountain chains. Comparative studies and experimental manipulations are needed to build broad inference into how past climate change has shaped the structure and function of whole ecosystems. The next era of sky island research is poised to create a model for climate change responses and eco-evolutionary dynamics, with profound conservation implications. Expected final online publication date for the Annual Review of Ecology, Evolution, and Systematics, Volume 54 is November 2023.

天空岛屿是预测气候变化的生态和进化后果的全球工具
天空岛是独特的地质构造,是自更新世以来经受住气候变化的生物种群的家园。天空岛屿和相邻山脉之间的长期隔离和气候差异导致天然实验室非常适合研究气候变化的直接影响。在这里,我们回顾了全球天空岛的文献,以研究分类群如何应对气候变化。结果表明,在遗传漂变和自然选择的驱动下,谱系形成、遗传变异减少和性状进化在不同分类群之间发生。由于栖息地的不断减少和天空岛屿相对于山脉的陡峭的选择性梯度,这些影响今天仍在继续。为了对过去的气候变化如何塑造整个生态系统的结构和功能建立广泛的推断,需要进行比较研究和实验操作。天空岛研究的下一个时代是准备为气候变化响应和生态进化动力学创造一个模型,具有深远的保护意义。预计《生态、进化和分类学年度评论》第54卷的最终在线出版日期是2023年11月。修订后的估计数请参阅http://www.annualreviews.org/page/journal/pubdates。

期刊介绍: The Annual Review of Ecology, Evolution, and Systematics is a scholarly publication that has been in circulation since 1970. It focuses on important advancements in the areas of ecology, evolutionary biology, and systematics, with relevance to all forms of life on Earth. The journal features essay reviews that encompass various topics such as phylogeny, speciation, molecular evolution, behavior, evolutionary physiology, population dynamics, ecosystem processes, and applications in invasion biology, conservation, and environmental management. Recently, the current volume of the journal transitioned from a subscription-based model to open access through the Annual Reviews' Subscribe to Open program. Consequently, all articles published in the current volume are now available under a CC BY license.
