Özet

The aim of the present research is to determine the different anthropogenic effects on the benthic macroinvertebrates
communities with some physico-chemical parameters in the two brooks (Çağlayan and İkizdere) of the East Black Sea Region of Turkey.
The study period is about one year and samples are collected seasonally from the upstreams to the down streams of the Brooks at least
from the five stations of each. Macroinvertebrate samples are collected with a Surber sampler, sampling area of 0.09 m2. Water
temperature, dissolved oxygen, electrical conductivity and pH are measured in situ. According to the preliminary observations; the taxonomic list of
benthic macroinvertebrate communities consist of the members of Tricoptera, Ephemeroptera, Diptera, Hemiptera, Plecoptera and Amphipoda
orders at the two Brooks in the autumn and winter samplings. Their abundances are changed from the upstreams to the downstreams by the
degree of the anthropogenic effects such as fish farms effluents, touristic areas, hydroelectric power stations, the stone breaker plants and the
sewages. In the poster, the preliminary results of the benthic macroinvertebrate communities and some physico-chemical parameters in the two
Brooks located in the same region under different pollution effects will be presented just for autumn and winter seasons in comparison.
