Species specific effects of three morphologically different belowground seagrasses on sediment properties

摘要: Abstract Roots and rhizomes of seagrass play an important role in coastline zone by anchoring the substrate firmly which prevent resuspension also controlling sediment biogeochemistry. The aim this study was to compare physical chemical differences sediments for 3 species, have different root morphology between summer (February 2013) monsoon month (September 2013). Seven communities were studied are: mono stand Halophila ovalis , Thalassia hemprichii Cymodocea rotundata mixed patches H. ovalis with T. hemprichii C. rotundata species. roots seagrasses main driver properties; branched, long showed increasing redox potential means oxygen releasing from their roots. unbranched, dense hair tended cause more poorly sorted sediments. carbon storage estimated results a trend higher organic density multispecific patches, specific bare sand, respectively. Season influenced high wave action stirred up sediments, led lower potential. Our suggest that species both increase decrease properties.
