Aquatic macrophytes of the Danube River near Novi Sad (Yugoslavia, river-km 1255-1260)
Janauer, Georg A.; Igic, R.
This study deals with a preliminary investigation of the aquatic vegetation of the Danube system at Novi Sad (Yugoslavia). The macrophyte survey in the main channel of the river and in one small oxbow was performed in 1998. Species richness in this reach of the main channel was intermediate with respect to parts of the river in other countries. The plant mass was very low and very small plant stands were developed. The oxbow is directly connected to the main channel at its lower end, but a considerably higher number of species was present than in the main channel. Only very small stands with low biomass were found. This indicates that there are many small niches in the near-bank habitats, but the hydrological dynamics prevent the development of larger vegetation patches.
