Effect of macrophytes on Phytophilous macroinvertebrate community
... Macrophytes are an essential direct and indirect resource in any aquatic ecosystem ranging from rivers, lakes to wetland and coastal areas. The periphyton inhabiting the plant surface provide a direct food source to the associated macro-fauna (James et al. 2000, Hillebrand, 2002) [60, 56]. Due to th ...
