Nghiên cứu nhằm đánh giá mối tương quan giữa chất lượng nguồn nước và sự phân bố động vật đáy ở kênh E, thành phố Cần Thơ. Mẫu mẫu được thu thập tại ba vị trí trên vào tháng 12/2018 4/2019. Phân tích định tính thực hiện cho thấy phần có 8 loài thuộc 4 họ lớp, mật độ sinh biến lớn các đợt khảo sát. Dựa loài, chỉ số học H’, ASPT, RBP III rất ô nhiễm. Chỉ VN_WQI từ thông lý - hóa của ghi nhận nhiễ...

The study was conducted in Karasu Stream (Sinop Province, Black Sea Region of Turkey). purpose this is, to determine the benthic macroinvertebrate composition stream, together with some its environmental characteristics (water temperature, pH and dissolved oxygen) evaluate trophic level stream. Samplings macroinvertebrates variables were performed monthly at ten stations between February 2013 J...

En el presente estudio se evalúa la calidad del agua en Ciénaga La Pachita (Cesar, Colombia) a través de análisis macroinvertebrados acuáticos asociados macrofita Eichhornia crassipes (Pontederiaceae), Buchón Agua. Se examinan variables físico-químicas diferentes periodos hidrológicos, estiman los índices diversidad alfa y beta determinan BMWP/Col ASPT. Como resultado colectan 1550 pe...

In this study, it was aimed to evaluate the water quality of Çoruh Basin using BMWP (Biological Monitoring Working Party) index, ASPT (Average Score Per Taxon) Shannon-Wiener Diversity Index, EPT (Ephemeroptera Plecoptera Trichoptera taxa), EP taxa) index scores and benthic macroinvertebrates. The macroinvertebrates were collected from 54 stations at basin between 2014-2016 years. Standard hand...

Aquatic insects are the utmost generally employed macroinvertebrates in freshwater monitoring and assessment worldwide. However, aquatic have received far less attention for objectives of health water quality bioassessment, particularly Kalaburagi, Karnataka. This study examined abundance Bhosga reservoir their relationship to physicochemical factors. Water ecosystem had been assessed using BMW...

A system of self-sustained biological clocks controls the 24-h rhythms of behavioral and physiological processes such as the sleep-wake cycle. The circadian clock system is regulated by transcriptional and translational negative feedback loops of multiple clock genes. Polymorphisms in circadian clock genes have been associated with morningness-eveningness (diurnal) preference, familial advanced...

Conflicts between replication and transcription challenge chromosome duplication. Escherichia coli replisome movement along transcribed DNA is promoted by Rep and UvrD accessory helicases with Δrep ΔuvrD cells being inviable under rapid growth conditions. We have discovered that mutations in a tRNA gene, aspT, in an aminoacyl tRNA synthetase, AspRS, and in a translation factor needed for effici...

Macrozoobenthos comprise an important group of aqua fauna by way their contribution to ecosystem stability, besides acting as potential bio indicators trophic status. Numerous plants and animals that have benthic aquatic terrestrial components-which are essential for life-find habitat in rivers. The Ghodha Pachad Dam, which is found the Bhopal district's Huzur tehsil, was subject current study....
