Abstract :

This study was conducted to examine the population ecology macrobenthos Kelerud Rivers of Babol (Mazandaran province) during 2010-2011 seasons were sampled at six stations. Benthic invertebrates collected by the sampler little surber sampler were isolated in the laboratory using a loop. Macrobenthos simultaneous sampling, hydrologic variables were recorded at each station. Generally benthic river wide crotch strap end and creams containing 5 Class 8 orders and 12 families. In total, category 5 orders and six families with the most diverse groups of insects in the river macrobenthic accounted for, of which the Ephemeroptera (day of) the most diverse and Plecopte (Springs) had the lowest variability in macrobenthic Kelerud River. The greatest diversity and abundance of all identified families with an average of 103 samples and 89/20 % belonging to the genus Heptagenia diversity and abundance with an average minimum of 3 and 60 / 0 % belonging to the family Gammaridae.
