Planktonic Rotifers in the tidal Guangzhou segment of the Pearl River Estuary, China

珠江广州河段轮虫的时空分布研究


2004年4月-2007年3月,对珠江广州河段轮虫群落结构的时空变化进行了三年的调查研究。调查期间,共发现轮虫56种。优势种为裂痕龟纹轮虫(Anuraeopsis fissa),微型多突轮虫(Proalides subtilis),西式三肢轮虫(Filinia novaezealandiae),角突臂尾轮虫(Brachionus angularis),尾突臂尾轮虫(Brachionus caudatus),暗小异尾轮虫(Trichocerca pusilla),蛭态目(Bdelloidea sp.)和萼花臂尾轮虫(Brachionus calyciflorus)。调查发现,珠江径流量对轮虫密度有重要影响。在丰水期,两个采样站点(分别为中大码头和黄埔码头)的轮虫密度变化不大,而在枯水期,位于下游的黄埔码头的轮虫密度显著低于上游的中大码头。轮虫的密度高峰出现在秋季(9月底至12月初)。中大码头轮虫的最高峰出现在2004年12月初,为5975ind./L;黄埔码头的轮虫高峰出现在2004年4月中旬,为5877ind.·L-1。轮虫密度变化范围为4~5975 ind.·L-1。中大码头轮虫密度的平均值为1627±233 ind.·L-1;而黄埔码头的平均值为1051±147 ind.·L-1

【摘要】 2004年-4月.2007年3月,对珠江广州河段轮虫群落结构的时空变化进行了三年的调查研究。调查期间,共发现轮虫56种。
优势种为裂痕龟纹轮虫(Anmaeopsisfissa),微型多突轮虫(Proalidessubt li ),西式三肢轮虫(Filinianovaeze landiae),角突臂尾
轮虫(Brachionmangularis),尾突臂尾轮虫(Braehionmcaudatus),暗小异尾轮虫(TrichoeercapmiUa),蛭态目(Bdelloideasp.)
和萼花臂尾轮虫(Braehionusealyciflorus)。调查发现,珠江径流量对轮虫密度有重要影响。在丰水期,两个采样站点(分别为中
大码头和黄埔码头)的轮虫密度变化不大,而在枯水期,位于下游的黄埔码头的轮虫密度显著低于上游的中大码头。轮虫的密度
高峰出现在秋季(9月底至12月初)。中大码头轮虫的最高峰出现在_2004年12月初,为5975indJL:黄埔码头的轮虫高峰出现在.2004
if-4月中旬,为5877ind.·L.1。轮虫密度变化范围为4-5975ind.-L"1。中大码头轮虫密度的平均值为16274-233ind.·L.1:而黄埔码头
的平均值为10514-147ind.·L.1。
