Identification, Distribution and Abundance of Macroinvertebrates and Biomonitoring of the Ghale Rudkhan River, Guilan Province
Benthic macroinvertebrate-based indices are suitable tools for assessment of stream health and human impacts on its biological integrity. Since Ghale Rudkhan River is an attractive tourist destination and its surrounding population is growing, its water quality was examined usning biological indicators. Macroinvertebrate samples were taken monthly by a Surber sampler (mesh = 300 µ and area = 90...
متن کاملSpatial and temporal distribution of benthic macroinvertebrates in a Southeastern Brazilian river.
Benthic macroinvertebrate assemblages are structured according to physical and chemical parameters that define microhabitats, including food supply, shelter to escape predators, and other biological parameters that influence reproductive success. The aim of this study is to investigate spatial and temporal distribution of macroinvertebrate assemblages at the Macaé river basin, in Rio de Janeiro...
متن کاملDistribution and abundance of high aquatic plants in the Gorganroud River, the Caspian Sea basin, Iran
The distribution and abundance of high aquatic plants in the Gorganroud River was examined at five stations in four seasons (20 samples) over one year period during 2009-2010. We identified 21 species of aquatic plants from 21 genera, belonging to 9 families. These species were determined as 3 halophytic species (14.2%) and 18 high aquatic plants (85.7%).The highest species diversity was observ...
متن کاملDistribution, Diversity and Abundance of Benthic Foraminifera of the Northwstern Persian Gulf
During ROPME Winter Cruise 2006, twenty six surface sediment samples taken from the Northwestern part of the Persian Gulf at depths of 13-77m were analyzed for their foraminifera content. A total of 93 species of benthic foraminifera were found in the study area. The foraminifera assemblages were dominated by Ammonia beccarii, Spiroloculina excavata, S. depressa, Quinqueloculina dimidiata,...
متن کاملBiological assessment of the Tang Sorkh River (Iran) using benthic macroinvertebrates
A biological assessment of the Tang Sorkh River (Iran) was studied from July 2013 to August 2014 using benthic macroinvertebrate communities. Samples were gathered every two months, from five stations using a Surber sampler( 30×30cm), fixed in formalin (4%) and then separated and identified in the laboratory. Environmental conditions (current velocity, temperature, depth, width, dissolve oxygen...
