Rotifers of Portuguese reservoirs in river Tejo catchment : Relations with trophic state
Twelve portuguese reservoirs were investigated in 1995 and 1996. These reservoirs suffer from the influence of several human activities. As a consequence, several reservoirs in the Tejo River basin are progressing towards eutrophication. The rotifer community was analysed using a Cluster Analysis an...

| Sumario: | Twelve portuguese reservoirs were investigated in 1995 and 1996. These reservoirs suffer from the influence of several human activities. As a consequence, several reservoirs in the Tejo River basin are progressing towards eutrophication. The rotifer community was analysed using a Cluster Analysis and a Canonical Correspondence Analysis (CCA). These analyses permitted the depiction different groups according to rotifer species distribution and abundance. These groups reflected, in general, differences of trophic state among reservoirs and seasonal variation. The results of the present study point to gradual responses of rotifer communities to eutrophication. |
