Rotifer Community Structure and Its Relationships With Environmental Factors in Mingcui Lake
摘要
Abstract
Rotifer species composition, density, biomass and the water environmenal factors such as Chlorophyll-a conen(ρ), water temperature(t), pH, secchi-depth(L), total nitrogen(ρ(N1)), total phosphorates(ρ(P1)), Potassium permanganate index(ρ(CODMn)) were analysed from Jan. 2009 to Oct. 2009 in Mingcui Lake. Analysis approaches of correlation analysis, multiple stepwise regression, path analysis and Canonical Correspondence Analysis were employed between Rotifer density, biomass, community and water environmenal factors in Mingcui Lake. The results showed that 3 sub-division, 8 family, 14 genera and 22 species of rotifer were idenified in Mingcui Lake. The dominan species were Brachionus calyciflorus , Keratella quadrata and Brachionus angularis. The correlation between rotifer density and ρ, t,pH, ρ(P,), ρ(CODMn) were positive, and that between rotifer biomass and ρ,t,pH, p(N1), ρ(P1), ρ (CODMn) were positive. The correlation between rotifer density, biomass and L was negative. Followed by the importance the water environmenal factors which had affected on rotifer density in Mingcui Lake ranged as follows:t, pH, ρ, ρ(P1),ρ(CODMn). Those affected on rotifer biomass ranged as follows;t, pH, ρ, ρ(P1), ρ(CODMn). CCA result showed that 15 species of rotifer were divided ino 3 groups in Mingcui Lake, t, ρ(COCMn), ρ, pH were the main water environmenal factors correlated with the distribution of rotifer community in Mingcui Lake.关键词
