The Great East Japan Earthquake, with a moment magnitude scale of 9.0M on March 11, 2011, caused huge tsunamis that altered aquatic communities in the nearshore ecosystems along Pacific coastline Sendai Bay, Japan. However, to understand ecological implications tsunamis' impact, an assessment successive changes and their fate over time is essential. Therefore, we examined eight tidal flat Bay a...

Abstract We report for the first time effects of vehicle traffic and beachgoer trampling on macrobenthic communities Amazonian sandy beaches. Sampling was performed during four consecutive months with different beach use intensity in 2017 (before, vacation, two after vacation period) three contrasting beaches regard to disturbance (Urban: Atalaia; Intermediate: Farol-Velho; Protected: Corvinas)...

the changes in density and biomass of macrobenthos were seasonally investigated from winter 2005 till fall 2006 in southern caspian sea. samples were taken with a 225cm2 van veen grab from depths of 7 and 20 meters along two transects: line 8 area (western part) and radio darya area (eastern part). totally, 5 classes of macrobenthos were identified of which the most abundant populations were po...

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...
