Distribution of invertebrates associated with aquatic plants in streams of the Eastern Chaco
This study of invertebrates was restricted to four streams. Their vegetated littoral zone was sampled once a season (in august 1984 and October 1984). Two sampies were collected at six sites with a net of 962 cm2 with a mesh size of 225 microns. Macrophytes and associated invertebrates shortly remai...

| Sumario: | This study of invertebrates was restricted to four streams. Their vegetated littoral zone was sampled once a season (in august 1984 and October 1984). Two sampies were collected at six sites with a net of 962 cm2 with a mesh size of 225 microns.
Macrophytes and associated invertebrates shortly remain in this water bodies during low water periods.
Different groups of invertebrates on the basis of chosen species according with their highest abundance and special distribution, were determined:
I-Stream species group represented by Simulium sp. and Rheotanytarsus sp.
II-Species living either in lentic and lotic environments (euryoecious species).III-Species occuring in high salinity waters.
Besides, the relative abundance of each group is discussed. |
