Spatial and temporal variation in pH, alkalinity and conductivity in surface runoff and groundwater for the Upper River Severn catchment

The data matrix was composed of 7 va- riables (water temperature, dissolved oxygen, pH, electrical conductivity, river level, precipitation index, and photoperiod), with 24

That can explain its dominance during high water period, mainly in Patos lagoon profundal region due to the lower oxygen concentration and the greater percentage of organic matter..

In fact, the riffle litter substrate had higher taxa in terms of richness and abundance, but the pool litter substrate had the greatest number of exclusive taxa.. A Cluster

The sand bar openings cause radical alteration of the physi- cal and chemical conditions including drastic reduction of water volume, perishing of freshwater communities

Cluster analysis based on the occurrence of plank- ton ciliate species in the different environment types from the Upper Paraná River floodplain (Cophenetic Correlation Coefficient

This study aims to evaluate the environmental factors determining of the changes in phytoplankton structure in spatial (upper, middle and lower course) and seasonal (dry and

We concentrated our efforts on only six lakes during six years of surveys. a) Detrended correspondence analysis (DCA) ordination of aquatic macrophyte communities surveyed between

In summary, our results revealed wide variability in the physical and chemical characteristics of habitats in the floodplain, which is caused by the distinct character- istics of
