Abstract:
Functional traits are indicators of the responses and adaptation of organisms to environmental changes and cascade to a series of ecosystem functions. The functional traits of soil animals are sensitive to environmental factors and may characterize and predict the changes of ecosystem functions. Multiple dimensions of biodiversity that combing species, phylogenetic, and functional diversity improves the understanding of distribution patterns, community assembly mechanisms and ecosystem functions of soil animals. In this review, we listed the categories of soil animal functional traits and their ecological significance, and summarized current researches on the responses of soil animal communities to environmental changes and the community assembly processes based on trait-based approaches. We proposed to strengthen the study on the impacts of eco-evolution processes of biotic interactions to soil animal functional traits, establish the database of soil animal functional traits, and apply trait-based approaches in the ecological restoration in the future, which would benefit soil biodiversity conservation and sustainability of soil ecosystems.
功能性状是生物对周围环境响应与适应的直观表现,同时影响一系列的生态系统功能。土壤动物的功能性状可较好地表征和预测环境变化及其所在生态系统的功能变化。综合物种、系统发育及功能性状的多维分析,有助于全面和深入理解土壤动物分布格局、群落构建机制及生态系统功能。本文在阐述土壤动物功能性状常用表征指标和生态学意义的基础上,系统分析了基于功能性状的土壤动物群落响应环境变化及其群落构建过程的相关研究进展,并提出未来在理论上应重点关注生物互作的生态进化过程对土壤动物功能性状的影响,在方法上应注重具有生态学意义的功能性状数据库的建立,还应重视利用功能性状与生态功能的关系指导生态恢复实践,促进土壤生物多样性保护及资源可持续利用。.
