摘要
底栖动物是红树林生态系统的重要组成部分。本文总结了近年来国内外红树林底栖动物的生物多样性、分布模式及其影响因素的研究进展,并从以下5个方面阐述了底栖动物(尤其是相手蟹)对红树林生态系统的影响:1)维持系统初级生产;2)丰富系统有机物生产;3)影响红树植物生长;4)降低幼苗竞争压力;5)改变沉积物性质。除传统的群落结构、生物多样性和个体生物学研究外,目前红树林底栖动物生态学的研究正逐步向红树林沙蟹等其他海洋无脊椎动物的种间关系、底栖生物区系与栖息地间相互关系研究发展。有必要重新认识蟹类的生物扰动对红树林更新和红树林生态系统能量流动的积极意义。
Benthic fauna is an important component of mangrove ecosystem.This paper summarized the research progress in the biodiversity and distribution of mangrove benthic fauna and related biotic and abiotic affecting factors,and discussed the influence of benthic fauna,especially Sesarmidae crabs,on the structure and function of mangrove ecosystem from the aspects of 1) maintenance of ecosystem primary productivity,2) enhancement of ecosystem organic matter production,3) effects on mangrove growth,4) mitigation of saplings competition stress,and 5) altering sediment properties.In addition to the traditional studies in assemblage structure,biodiversity,and idiobiology,the current researches on the ecology of mangrove benthic fauna are paying more attention on the interactions between the benthic fauna and other marine invertebrates (e.g.Ocypodidae),and the intra-and inter-relationships between benthic fauna and its habitats.It is necessary to further understand the significance of crabs' biotrubation in the natural regeneration of mangrove and the energy flow of mangrove ecosystem.
