贵州草海后生浮游动物群落季节动态特征及与环境因子的关系
Metazooplankton community structure and its relationship with environmental factors of Caohai, Guizhou Province, China
摘要
Abstract
To understand the community structure of metazooplankton in Caohai, Guizhou and explore the relevant physicochemical factors on their distribution, we conducted seasonal investigations in 10 sites in the Caohai in October 2016 and January, April, July 2017.Non-metric multidimensional scaling analysis (NMDS) and redundancy analysis (RDA) were used to study the community structure of metazooplankton.Forty-five metazooplankton species were identified (excluding protozoa), and most of them were rotifers (32 species) having the highest abundance.The seasonal difference in metazooplankton abundance bwiaosm saisgsn wasificantsi, ghniigfihceastnti, nhsipgrhinesgt (in52sp87riinndg.· (18L-1).3a0n mg·L-1) d lowestanindw loweinter (st7 i3.n2 s0uinmd.m·eLr-1 () ;1 t.50hemg·L-1) seasonal.Thedifferedominnce inamnet t speciesazooplanwerekton Keratella cochlearis, Keratella quadrala, Brachionus calyciflorus.In spring and summer, the dominant species were Keratella cochlearis.There were no distinct dominant species in autumn and winter.Spatial location maps of samples obtained through NMDS, with four distinct seasons, reflected the hydrologic seasonality of the community structure.RDA showed that water temperature and secchi disk depth were the key factors affecting the metazooplankton community structure.Nutrients, pH and chlorophyll a were the important factors affecting the metazooplankton community structure.关键词
