In this study, for determining the effect of trophic state and the other physicochemical variables on the dynamic of benthic macroinvertebrates of Küçükçekmece Lagoon Lake, water and sediment sampling were performed at five stations at seasonally during a year between 2014-2015. A total of 6 benthic macroinvertebrates taxa comprised of 350 individuals per m2 at average were found in the lake. The water samples analysed to determine physicochemical variables (water tempature, pH, conductivity, DO (dissolved oxygen), TDS (total dissolved solids), salinity. NO3-N, NO2-N, SO4-2, PO4-3, SiO2, chlorophyll-a, TP (total phosphorus), and secchi disc) and the similarity of seasons and stations in the lake in relative to the benthic macroinvertebrates and physicochemical variables were showed by Bray-Curtis Similarity Index. According to the Carlson Trophic State Index (CTSI) made to determine the trophic state, the water of the lake showed a eutrophic character during all seasons of the year. In addition, the relations between physicochemical variables and benthic macroinvertebrates were compared statistically by Canonical Correlation Analysis (CCA). As a results, it was concluded that the dominance of the taxa detected from the lake was quite low and this was due to the eutrophic conditions that occurred as a result of the increasing pollution in the lake.

“…Tubificidae family is able to tolerate low oxygen conditions; even in the concentration of oxygen gas is approaching 0 mg/L (Yule & Yong 2004;Gooderham & Tsyrlin 2003). It often is used as indicators of aquatic habitats polluted organic environment (Lobo & Alves 2011;Gooderham & Tsyrlin 2003). In this study, the Tubificidae family was found in downstream stations (Station 4, 5 and 6).…”

“…Besides, Moore (1979) emphasizes the importance of organic matter on the distribution of benthic macroinvertebrates. Presence of organic material increase the concentration of algae which becomes food source for Tubificidae (Lobo and Alves 2011) Erpobdellidae is grouped under Hirudinea taxa. The Erpobdellidae was only found in Station 6 which density as 24 ind/m 2 .…”

“…River bed composition is recognized to affect a significant impact on the biomass and diversity of benthic macroinvertebrates (Flores & Zafaralla 2012). The characteristics of river are essential to the survival and reproduction of benthic macroinvertebrates as well as supporting their respiratory process (Lobo & Alves 2011). Muñoz & Prat (1996) state that density of benthic macroinvertebrates families will be decreased in polluted areas.…”

This study applies the Principal Component Analysis (PCA) to evaluate and interpret the relationship between water quality and benthic macro-invertebrates fauna data obtained from Pauh River, Cameron Highlands. Samples were collected once every two months (in February, April, June, August and October 2013) with six chosen sampling stations. Six water quality parameters namely dissolved oxygen (DO), pH, biological oxygen demand (BOD5), chemical oxygen demand (COD), ammonia-nitrogen (NH3-N), total suspended solid (TSS) and heavy metals contents were analyzed according to American Public Health Association (APHA), Standard Methods for Examination of Water and Wastewater (1998). Macro-invertebrates were also sampled using Surber sampler and were identified until their family level. Water Quality Index (WQI) values for all stations were class II except for the station 6 which was recorded as class III. Both the diversity and biotic indices showed decreasing value from the upstream (Station 1) to downstream (Station 6). A total 28 to 31 taxa have been found in Station 1, 2, 3 and 5 (upstream to middle stream). However, only 7 taxa found at station 6 (downstream). Total 31 taxa with an average density 368.28 ind/m2 were found in Station 4 which was highest number of taxa among the monitoring stations. The principal component analysis (PCA) was applied on the dataset, which explained 72.15 % of the total variance of the variables. Three components were extracted in this study. First component was classified as benthic macroinvertebrates which tolerated to low water quality condition and high loading of organic matters. The benthic macro-invertebrates families loaded in second component were sensitive to water environment such as NH3-N, dissolved oxygen (DO), organic matter and stream flow. The benthic macroinvertebrate families loaded in third component were recognized as species which might not tolerate low concentration of dissolved oxygen.

The presence of fine sand in the muddy sediments affects habitat selection and accelerates the growth rate of Limnodrilus hoffmeisteri and Limnodrilus claparedianus (Oligochaeta)

Assessment of food conditions for animals is usually based on the quality and quantity of available food, whereas less attention is paid to other factors affecting the processing of ingested food. One of the commonly used mechanisms involving non-digestible objects from the environment is lithophagy (using swallowed stones or sand grains as gastroliths). Therefore, the aim of this laboratory study was to investigate the impact of sand present in muddy bottom sediments on ubiquitous freshwater oligochaetes: Limnodrilus hoffmeisteri and Limnodrilus claparedianus. They belong to the most common tubificid species and, as detritivores, play crucial role in the functioning of water ecosystems. We showed that the presence of sand in the environment has positive effects on oligochaete habitat preferences and growth. They selected the mixture of mud and 60–160 µm sand over pure mud and mud with larger sand fractions. Their growth rate was highest in the sediments with an admixture of this sand fraction, and simultaneously the largest number of sand grains of this size was found in their digestive tracts. In our opinion, the oligochaetes used the sand grains to grind the ingested food, which should accelerate digestion and nutrient assimilation, and stimulate their growth rate.
