东寨港红树林凋落叶附生小型底栖动物的群落特征及影响因素
Community characteristics and factors affecting meiofauna on mangrove leaf litter from Dongzhai Harbor
摘要
Abstract
Meiofauna is an important component of the mangrove ecosystem.Thus,it is important to elucidate the community characteristics of mangrove meiofauna to gain knowledge on the biodiversity,monitoring,and evalua-tion of the mangrove ecosystem's health.The meiofauna on leaf litter and the sediment from five typical mangrove forests were investigated in Hainan,Dongzhai Harbor National Nature Reserve,China,in November 2020 to study the community characteristics and factors affecting meiofauna.A total of 12 meiofaunal groups were identified,and the relative abundances of nematodes and copepods were 67.67%and 29.31%,respectively.The average abundance of epiphytic meiofauna was(5.27±3.35)ind·g-1,and the average biomass was(4.94±2.35)µg dwt·g-1.The abun-dance and biomass of epiphytic meiofauna were significantly different among the five mangrove forests.The abundance and biomass of meiofauna in Avicennia marina and Rhizophora stylosa were higher than those of other mangrove forests,whereas the abundance and biomass of meiofauna in the mixed forest were the lowest.The abundance and biomass of meiofauna were negatively correlated with the content of soluble condensed tannins and the sorting coefficient,whereas they were positively correlated with the skewness coefficient.A combination of environmental factors,including the contents of chlorophyll a and cellulose condensed tannins,as well as the sort-ing and skewness coefficients,clearly explained the community structure of meiofauna.These results not only pro-vide basic data for an overall understanding of the mangrove ecosystem but also new perspectives for future studies on the structure and function of mangrove ecosystems.关键词
