Function of Ficus in tropical rainforest ecosystem in Xishuangbanna

Abstract

Abstract: Figs are one of the key species in the tropical rainforest of Xishuangbanna.Through offering habitats and foods to all kinds of animals,plants and microorganisms,they help to maintain the biodiversity in the tropical rainforest ecosystem.Some species of figs are stangler plants which play important roles in the succession and renovation of forests.Some of the species are pioneers which can accelerate the progress of vegetation restoration.The protection of Ficus species in the rainforest of Xishuangbanna is a critical step in maintaining the structure and function of the rainforest ecosystem.However,the overexploitation has made the tropical rainforest fragmented and resulted in significant decrease in fig population sizes and the quantity variation in species and populations of fig wasps and frugivores which feed on figs.Only the colony of Ficus was conserved,which is one of the important measures,could the whole ecosystem of the tropical rainforest be rehabilitated.
