Some aspects of the distribution and dynamics of the benthic macroinvertebrate groups from Nimăieşti valley river

| Summary: | In the Nimăieşti Valley river we found in a number of four sample sites a community of benthic macroinvertebrates represented by Oligochaeta, Ephemeroptera larva, Trichoptera larva, Chironomida larva and Hidracarina species. The communities structure vary depending on season and the sampling site acording to the water quality and trophic condition of the substrate. The greatest diversity was recorded during the summer months (may-august) and comparing the sample sites, we found that the first three sampling sites are very similar from the point of view of the macroinvertebrate community, but the fourth sampling site the community is different because the river pases through the town of Beiuş and as a consequence the water quality is lower that at the other three sample sites. |
