Benthic Invertebrates of the Lower West River
The purpose of this study was to document existing benthic organisms of the lower West River in New Haven and West Haven, Connecticut, in order to enable monitoring of salt marsh restoration. Seventeen sites were sampled between the Chapel Street Bridge and the mouth of the West River during the month of July 1995. All sites contained polychaete worms and other organisms typical of estuarine sy...
متن کاملDiversity and Spatial Structure of Benthic Macro-Invertebrates Community of Calabar River, Nigeria: Implications for Bio-Monitoring of River Environmental Quality
The study was carried out to ascertain benthic macro-invertebrates checklist in the Cross River, Nigeria and using it for bio-indication of the river quality. A total of 186 benthos specimens were collected. The phylum Insecta was most abundant (96) representing 51.61% of total benthos abundance; followed by Oligochaeta 60 (32.25%), Nemertea 10 (5.37%), Hirudiae 8 (4.3%), Cladocera 6 (3.22%), A...
متن کاملThe effect of Rainbow trout farms effluents on benthic macro-invertebrates of Marber River in Semirom
The effect of Rainbow trout farms effluents on benthic macro-invertebrates of Marber River in Semirom city was investigated in spring and summer of 2013. Sampling from benthic macro-invertebrates was done monthly using Surber sampler (mouth area of 30.5 * 30.5 cm with a 500 mesh net) at entrance, discharge and far from three fish farms. In addition to measuring physical and chemical parameters ...
متن کاملTemporal variations of benthic diatom community and its main influencing factors in a subtropical river, China.
Benthic diatoms are the main component in many aquatic ecosystems such as streams, creeks and rivers, and they function as important primary producers and chemical modulators for other organisms in the ecosystems. In this study, the composition of benthic diatoms was investigated and further explored the primary physicals and chemicals affecting their temporal variations in the upper Han River,...
