摘要:

岛屿因数量众多、自然隔离、形成历史多样等独特的地理特征,成为生态学和进化生物学研究的天然实验室。相较于大陆,岛屿生物具有很高的特有性和失调性,这为探究岛屿生物多样性的形成提供了良好的机遇。本文围绕岛屿生态系统,从岛屿生物多样性的形成、维持和丧失3个部分阐述近些年国内外的岛屿生物地理学研究进展。对于岛屿生物多样性的形成机制,本文以全球几个代表性的岛屿系统为例,从物种的扩散迁入、种群建立和选择、物种进化和适应性辐射等过程介绍岛屿生物多样性的形成机制。以岛屿生物地理学平衡理论为基础,回顾了种-面积关系、种-隔离度关系,着重对戴蒙德法则、嵌套格局、岛屿生物群落结构理论框架和岛屿生物种间互作等群落构建方面的研究进展进行了论述。在岛屿生物多样性的丧失机制,从自然和人为因素两方面探讨了岛屿物种所面临的严峻的灭绝风险,尤其是生境丧失和改变、气候变化、外来物种入侵以及这些因素的协同作用对岛屿生物多样性丧失的影响。最后,基于岛屿生物多样性的现状,总结了目前国内外对岛屿生物多样性的保护措施和展望了未来可能的主要研究方向。

Abstract:

Due to the unique geographical features of large numbers, isolated by water and diverse formation histories, islands have become natural laboratories for ecological and evolutionary research. Islands have a high proportion of endemic species and disharmony in representing the species compared with that in the continent, which provides a good opportunity to explore the formation of island biodiversity. In this review, we focuse on island ecosystems and describes the progress of research in island biogeography in recent years from three aspects: formation, maintenance, and loss of island biodiversity. First, we take several representative island systems in the world as examples to introduce the formation mechanism of island biodiversity from species dispersal and immigration, population establishment and selection, species evolution and adaptive radiation. Based on the Equilibrium Theory of Island Biogeography, we then review the species-area relationship and species-isolation relationship and focus on the research progress in community assembly, including Diamond’s rule, nestedness pattern, the framework of community structure of island biota, and species interactions on islands. We also discuss the high extinction risks of island species threatened from natural and human disturbances, especially from the impact of habitat loss and change, climate change, alien species invasion and the synergistic effect of these factors on the loss of island biodiversity. Finally, based on the status of island biodiversity, we summarized the current conservation practices for island biodiversity and possible research frontiers in island biogeographic studies.
