“…Meanwhile, all macroinvertebrate taxa avoid founding at S2 due to high ammonia (NH 3 ) and nitrate (NO 3 ). Ammonia and nitrite can be extremely toxic for macroinvertebrates (Berenzen et al, 2001).…”

Biological assessment is considered a useful tool for assessing the ecological status of the aquatic ecosystems. Therefore, the goal of the present study was to use phytoplankton and macroinvertebrates as biological tools for ecological assessment of the River Nile around Gizert El-Warrak. A total of 33 phytoplankton species were recorded at the studied stations; these include 16 species of Chlorophyta, 5 Cyanophyta and 12 Bacillariophyta species. All investigated stations were characterized by high organic pollution according to Palmer′s index. Trophic state index showed a hyper-eutrophic status in stations S1, S2, S4, S6 and S8 and an eutrophic status in stations S3, S5 and S7.Gastropoda and Oligochaeta were the most dominant of macroinvertebrates taxa recorded 50.8 and 24.6% of all biota, respectively. Diversity Index (H′) ranged between (1.14 -2), which indicated that the structure of macroinvertebrate habitats was poor. Moreover, Evenness Index (J) ranged between (0.016 -0.043), which indicated that individuals were not distributed equally. The values of biotic index (HBI) depending on macroinvertebrates categories showed that the River Nile's water quality is fairly poor with significant organic pollution.

“…Zebra mussels excrete NH 4 þ as an end product of their metabolism, and NH 4 þ accumulates in the surrounding water (Heath et al 1995). Amphipods are very sensitive to NH 4 þ contamination, which can be lethal at high concentrations (Williams et al 1986, Berenzen et al 2001. Thus, the amphipods in our experiments might have avoided living mussels because of NH 4 þ accumulation in the chamber.…”

Abstract. In the last decades, zebra mussels (Dreissena polymorpha) have invaded many freshwater systems with severe consequences for entire communities. Most benthic macroinvertebrates, especially amphipods and chironomids, increase in abundance in the presence of zebra mussels. Increased structural complexity and an unknown biotic factor lead to this effect. Dreissena-associated factors that might influence populations of the native Gammarus roeselii and the invader Dikerogammarus villosus in Lake Constance, Central Europe, were investigated in laboratory experiments. These factors were: 1) increased structural complexity related to mussel shells, 2) Dreissena biodeposition, 3) chironomids, the presence of which is increased by biodeposited matter, and 4) Dreissena kairomones. In habitat-choice experiments, the native and omnivorous amphipod G. roeselii showed a preference for mussel shells with biodeposited material and for mussel shells with biodeposited material with chironomids, whereas the invasive and predatory amphipod D. villosus showed a preference only for mussel shells with biodeposited material with chironomids. In a kairomone y-maze experiment, both amphipods avoided zebra-mussel-conditioned lake water. These results indicate that habitat complexity and food availability, mediated directly or indirectly through biodeposited material, are the factors by which amphipod abundances are increased in the presence of Dreissena. Thus, biodeposited material can form an important new food resource, translocated from the pelagic zone to the benthos by zebra mussel filtration, and this biodeposited material might support a new detritus-based food web in the benthos.

“…In general, nitrite is absent or in very low concentrations in clean waters. Having higher nitrite concentrations is not favorable condition in freshwaters because of possible toxic effects on aquatic organisms (Berenzen, Schulz & Liess, 2001). Observing alteration in nitrite values indicates industrial and domestic pollution in aquatic habitats (Girgin & Kazancı,l997).…”

The study was conducted in Nif Stream (İzmir) and the aims of the study are (a) to determine the benthic macro-invertebrate composition of the stream, (b) to determine environmental features of the stream, (c) to investigate the relations between the determined species and the environmental variables and (d) to assess the trophic level of the stream which was under the pressure of industry, agriculture and settlement. Samplings of macrobenthic invertebrates were performed seasonally at eight stations between October 2013 and September 2014 in addition to measuring environmental variables of the localities. 11571 specimens were investigated and totally 77 taxa were determined. Chironomidae and Oligochaeta were the higher groups in terms of species richness with 25 and 17 species, respectively. Multivariate analyses indicate that pH, Ca 2+ and NO 3 -N were the most effective variables and explained 48.6% of the variance in the distribution and abundance of benthic macroinvertebrates in Nif Stream. Along the measured physicochemical characteristics and scores of biological indices, the upper branches of the stream have good quality water while the middle and lower parts are heavily polluted.
