“…Macrophytes can support a high associated biodiversity in the Neotropics, as observed in many regional case studies (e.g. : Meschiatti et al, 2000;Elmoor-Loureiro, 2007;Maia-Barbosa et al, 2008;Güntzel et al, 2010;Panarelli et al, 2008Panarelli et al, , 2010Ferrareze and Nogueira, 2011). The spatial complexity generated by the aquatic plants, and the consequent increase in microhabitat availability, is a major contributing factor for its biodiversity (Nogueira et al, 2003;McAbendroth et al, 2005;Thomaz et al, 2008;Thomaz and Cunha, 2010;Ferreiro et al, 2011), especially when compared to the relatively homogeneous limnetic zones (e.g.…”
