River plants from an Iberian basin and environmental factors influencing their distribution disturbance were significantly related to the species distribution. Species positioned at the axes extremes could be arranged into species groups related to different geographical areas of the river system.

Macrophyte cover and standing crop in the River Scorff and its tributaries (Brittany, northwestern Fespectively. In the stream, mean summer standing crops were 28 g of dry weight per m. (gDW/m.) in shaded and 58 gDW/m. in sunny stretches. In the main river, the average biomasses (with reduced standard deviation) were 96 and 187 gDW/m. for shaded and sunny stretches, respectively. These results are

Macrophyte functional variables , species assemblages as predictors of trophic status in flowing wat: both by a model based on MTR (. = −0.585, .<0.001), and by models using functional attributes of the macrophyte vegetation. River Trophic Status Indicator (RTSI) models based on ranked plant functional group relationship to river water P concentrations (RTSI.), or field-measured trait sets of the

Komplexe Analysis für Ingenieurerespectively. Plant emergence in relation to propagule density for all the species ranged from 24% to 56%, and no differences were found between irrigation and drainage channels. Results are discussed in relation to the established vegetation and the different management and environmental conditions

This applies in particular to an area where the water is fertilised by excreta from a pelican colony. Flowering of . appears to be markedly enhanced when vegetative reproduction is inhibited by crowd
