Chronological studies (1951–1995) of the changing land use in three river basins belonging
to the Tagus fluvial system (Portugal) were conducted using remote sensing data. The …

River plants were studied at 119 sites from a southern Iberian river basin. A site length of 50–
100 m was found to be adequate for characterising local plant richness in these rivers …

Biological traits of aquatic and riparian plants were compared among invasive and non-
invasive groups of species from both native and exotic taxa in Portuguese fluvial systems …

Population growth in urban areas changes freshwater ecosystems, and this can have
consequences for macrophyte communities as can be seen in the municipalities that border …
