Comparison of trophic structure of the benthic macroinvertebrates in three Bulgarian riverine water bodies

The trophic structure of benthic macroinvertebrates in three different types of running water bodies subjected to varyingdegrees of anthropogenic pressure was analyzed. A seasonal survey was conducted at three Bulgarian rivers in 2011. An adapted versionof the multihabitat sampling method was applied along with measuring physical and chemical variables. The ecological status wasdefined by means of biotic and trophic indexes. Distribution of the functional feeding groups shows that the most sensitive groups,shredders and scrapers, dominate the trophic structure of the mountain river types. In contrast, groups of deposit feeders and filterersprevail at the foothill and plain rivers. Multidimensional scaling plot and redundancy analysis demonstrated that anthropogenicimpact and altitude are the main factors determining the distribution of the benthic macroinvertebrates by different functional groups.Seasonality has no leading role in the trophic structure formation of the benthic communities. Our results showed a difference betweenthe trophic composition of the macrozoobenthos found in the mountain sections and those found in the foothill/plain stretches of therivers. A comparison between the last two areas demonstrated that there was no clear distinction between the trophic composition ofthe functional feeding groups.
