Characteristics of zooplankton community in cotai ecological reserve,Macao
摘要
Abstract
Two sampling zones and six sampling points were set up in the Macao Cotai Ecological Reserve in January,April,July and October 2013-2021 to investigate and analyze the spatial and temporal changes in the zooplankton community structure,and to make a preliminary assessment of the disturbed status of the water body.The results showed that 171 species of zooplankton(including 9 types of zooplankton larvae)were identified in the Cotai Ecological Reserve,of which 156 species were identified in Zone I and 116 species were identified in Zone II.The zooplankton belonged to 8 taxa,and the main dominant taxa were rotifers(57 species),copepods(48 species),and ciliates(33 species);the abundances of the zooplankton in Zone I ranged from 6.00-240.33 ind/L with an average of(59.27±58.39)ind/L,and zooplankton abundance in Zone II ranged from 3.00 to 62.58 ind/L,with an average of(19.20±16.82)ind/L.Regional differences in the structure of zooplankton communities in Zones I and II were significant,with the number of species and abundance in Zone I significantly greater than those in Zone II.The Shannon-Winner diversity index,the Margalef richness index,and Pielou evenness index in Zone I were significantly smaller than those in Zone II,and the interannual variation of zooplankton abundance in Zone I is larger than that in Zone II,which shows that the environment of Zone I is more sensitive than that of Zone II,and that Zone I is more affected by human activities.The dominant zooplankton species was mainly rotifers(pollution indicator species)in 2013-2016,and the dominant zooplankton species was mainly copepods(non-pollution indicator species)in 2017-2021,with a turnover rate of 100%.Except for Shannon-Winner diversity index of Zone I in 2017-2021,which was less than that in 2013-2016,the biodiversity indices of the two zones were greater than those of 2013-2016,which suggests that there has been an improvement in water quality of the reserve.关键词
