Effects of natural banks of free-floating plants on zooplankton community in a shallow subtropical lake in Southern Brazil

Abstract: The aim of this study was to test the effects of natural free-floating plants on zooplankton distribution in a shallow

“…Considering our results and the fact that free-floating macrophytes host rich macroinvertebrate and fish communities Meerhoff et al, 2007;Fontanarrosa et al, 2012), within the frame of environmental heterogeneity and following the concepts by Tews et al (2004), we propose that free-floating macrophytes constitute 'key structures' in vegetated floodplain shallow lakes, as they determine a quantitative change on the diversity of a variety of groups. Although the role of free-floating macrophytes as zooplankton hosts has been explored (Serafim et al, 2003;Gazulha et al, 2011;Villabona-González et al, 2011), rotifers were seldom considered, even though they are usually the most abundant and diverse group in subtropical and temperate shallow lakes (Meerhoff et al, 2003;Iglesias et al, 2007;Meerhoff et al, 2007). More diverse communities comprise species with different strategies to exploit resources and thus are more efficient and stable (Ptacnik et al, 2008;Cleland, 2011).…”

“…Emergent macrophytes play a similar role, especially in turbid ecosystems, where submerged macrophytes are limited (Iglesias et al ., ; Cazzanelli et al ., ). Finally, free‐floating macrophytes reduce light penetration and oxygen availability in the water column (de Tezanos Pinto et al ., ; O'Farrell et al ., ) and while reducing phytoplankton diversity (O'Farrell et al ., ) are associated to rich communities of zooplankton (Serafim et al ., ; Gazulha et al ., ; Villabona‐González et al ., ), macroinvertebrates (Poi de Neiff, ; Fontanarrosa et al ., ) and fishes (Agostinho et al ., ; Teixeira de Mello et al ., ).…”

“…This has been changing due to studies promoting faunal surveys in protected areas, like some in the states of Minas Gerais, São Paulo, and Rio Grande do Sul (Gazulha et al 2011;Rocha et al 2011;Santos-Wisniewski et al 2011). In the Brazilian Cerrado, at least six areas destined for protection have already been sampled, and the results for the survey of Cladocera are available in the literature (Elmoor-Loureiro and Mendonça-Galvão 2008; Sousa and Elmoor-Loureiro 2008.…”

“…Outros estudos revelam que a alelopatia exercida pelas macrófitas pode afetar cianobactérias (Nakia et al, 1999), o fitoplâncton (Mulderij et al, 2005), macroinvertebrados e o zooplâncton (Gopal & Goel, 1993). Gazulha et al (2011), em um lago tropical, encontraram uma densidade alta de microcrustáceos em macrófitas flutuantes, contradizendo o efeito da alelopatia sobre a distribuição dos microcrustáceos.…”
