The Relationship between the Distribution of Common Carp and Their Environmental DNA in a Small Lake
Although environmental DNA (eDNA) has been used to infer the presence of rare aquatic species, many facets of this technique remain unresolved. In particular, the relationship between eDNA and fish distribution is not known. We examined the relationship between the distribution of fish and their eDNA (detection rate and concentration) in a lake. A quantitative PCR (qPCR) assay for a region with...
due to successes of fingerprinting method in producing rapid and low-cost information of sediment sources, in this research this method was used in three sub-cathments of chasht-khoran basin in semnan province: amrovan, atari and ali-abad. samples below 63 μm were separated and 15 fingerprinting propertis was measured. in the first stage comparison of means and differentiation analysis were use...
Being available the accurate data on carried sediment has accounted as an important factor for making decision about constructing of river structures and determining of dam life. To accomplish this object, a number methods have been proposed so that sediment rate curving as a hydrological method has been developed for doing it. Ignoring differences between season's values causes to lower the pr...
In order to quantitatively evaluate the sediment yield in ungauged basins, it is necessary to use empirical models. The EPM model, as a model which is using in Iran, has sometimes been evaluated. Most evaluations have often been conducted by using river's sediment information and direct measurements of dam reservoir sedimentation have been less used, while the sediment measurement method on r...
Microbiological studies in a modified extensive shrimp culture system at Nambuthalai, southeast coast of India were carried out fora period of 120 days. Population dynamics and distribution profile of luminous bacteria and total heterotrophic bacteria in the water sediment and animal samples were monitored. Luminous bacteria associated with exoskeleton, gills and gut were isolated and quantifie...
Galactosylated BSA (galBSA) and its conjugate to horseradish peroxidase (galBSA-HRP) enter the galactose-specific pathway of hepatocytes. 10 min after intravenous injection, structures containing either ligand sediment mostly between 33,000 and 3 X 10(6) g X min (LP fraction) and have an equilibrium density of 1.11-1.13 g/ml in sucrose gradients (Quintart, J., P. J. Courtoy, J. N. Limet, and P....
