Research regarding the changes that occur in the structure of benthic macro invertebrates communities as a result of anthropogenic activities

Anca-Andreea Marin


An important role in the monitoring of the water quality is represented by the benthic macro invertebrates. They are a key component in the transfer of matter and energy in the aquatic ecosystems.

In May 2015, 20 quantitative samples of benthic sample were collected at different seasons in the Bega River water. Samples were collected from the upstream, middle and downstream of Timisoara city.

The aim of this paper is to identify the changes that occur in the structure of benthic macro invertebrates communities due to anthropogenic activities.

Once the identification of  saprobionte organisms has done, it have been performed the density, abundance and frequency of the sample. Based on these values, we can say that the upstream segment waters falls into the category of superior quality compared to the waters of the central segment, especially in the downstream segment.
