Abstract
The distribution characteristics of zooplankton in shallow urban lakes of Lingnan that in the tropics and subtropics were studied. The results showed that Brachionus, Trichocerea, and Lecane were dominant species of composition and abundance. The abundance of large Cladocera was low, which was affected by high water temperature, food restriction, and predation pressure of fish. Rotifera, small Cladocera, and Nauplius were the main zooplankton. Combined with the analysis of typical tropical shallow urban lakes, the dominant zooplankton tended to have a small individual population. It was expected to provide a reference for the ecological restoration of tropical shallow-water urban lakes.
Highlights
There had been some studies on zooplankton in some tropical regions of Asia, Africa, South America, and Australia, The comparative analysis of zooplankton in some tropical and temperate freshwater waters showed that tropical zooplankton had some unique characteristics[1]
Some studies had shown that Rotifera, small Cladocera, and Nauplius were the main zooplankton in tropical and subtropical zones compared with temperate zones [5]
The dominant species of zooplankton in Lingnan urban lakes were Polyarthra trigla, Schizocerca diversicornis, Brachionus forficula, Brachionus calyciflorus, Brachionus angularis, Anuraeopsis fissa, Trichocerca capucina, Filinia longiseta, Asplanchna brightwelli, and Nauplius et al, which could be found in most lakes with high abundance
Summary
There had been some studies on zooplankton in some tropical regions of Asia, Africa, South America, and Australia, The comparative analysis of zooplankton in some tropical and temperate freshwater waters showed that tropical zooplankton had some unique characteristics[1]. Through the investigation and sampling of zooplankton in the urban lakes of Lingnan, the species composition, abundance, dominant species, dominance of zooplankton were preliminarily understood. It showed that the characteristics of zooplankton in the urban lakes of Lingnan were similar to those in the tropics but different from those in the temperate zone, and the reasons for the differences in the distribution of zooplankton were analyzed
