Marginal lakes are characterised by their having high biological diversity due to the presence of aquatic macrophytes in their coastal zones, providing habitats for refuge and food for animal community members. Among the fauna components associated with macrophytes, aquatic macroinvertebrates are important because they are an energy source for predators and fish. In six lakes and two different seasons (March and August 2009), the ecological attributes of aquatic macroinvertebrate community associated with Eichhornia azurea were compared and the controlling environmental factors were identified. Since the attributes of macroinvertebrate community are strictly associated with abiotic variables of each distinct habitat, our hypothesis was that each site associated with the same floating aquatic macrophyte (E. azurea) should have a typical composition and density of organisms. We identified 50 taxa of macroinvertebrates, with greater taxa richness for aquatic insects (37 taxa) divided into eight orders; the order Diptera being the most abundant in the two study periods. On the other hand, higher values of total taxa richness were recorded in August. Dissolved oxygen and pH presented the greatest number of significant positive correlations with the different taxa. The animals most frequently collected in the six lakes in March and August 2009 were Hirudinea, Oligochaeta, Hydrachnidae, Conchostraca, Ostracoda, Noteridae, Ceratopogonidae, Chironomidae, Culicidae, Caenidae, Pleidae, Aeshnidae, Libellulidae, Coenagrionidae and Nematoda. Only densities of Trichoptera, Ostracoda and Conchostraca presented the highest significant differences between lakes in both study periods and considering the composition of macroinvertebrates no significant differences were registered for macroinvertebrate composition.Keywords: phytofauna, aquatic macrophyte, marginal lakes. Macroinvertebrados aquáticos associados à Eichhornia azurea (Swartz) Kunth e suas relações com as variáveis abióticas em ecossistemas lênticos marginais (São Paulo, Brasil) ResumoLagoas marginais são caracterizadas por apresentar elevada diversidade biológica, devido à presença de macrófitas aquáticas nas suas zonas litorâneas, constituindo habitats de refúgio e alimento para comunidades associadas. Entre os seus integrantes, destacam-se os macroinvertebrados aquáticos, fonte de energia para predadores e ictiofauna. Em seis lagoas e em duas épocas distintas (março e agosto de 2009), os atributos ecológicos da comunidade de macroinvertebrados aquáticos associados à Eichhornia azurea foram comparados, identificando-se os fatores ambientais controladores. Uma vez que os atributos da comunidade de macroinvertebrados estão estritamente associados às variáveis abióticas de cada habitat distinto, nossa hipótese era de que cada local com a presença da mesma macrófita aquática flutuante (E. azurea) deveria ter uma típica composição e densidade de organismos. Foram identificados 50 taxa de macroinvertebrados, com maior riqueza registrada para os insetos aquáticos (37 ...

“…These positive effects of E. crassipes on macroinvertebrates have been previously reported by other scientists. For examples, O'Hara (1967) found that the macroinvertebrates in the roots of E. crassipes were typical benthic species, and macroinvertebrate abundance was greater within the root sphere of E. crassipes than in benthic samples or within other plantroot systems in Lake Okeechobee, Florida; Brendonck et al (2003) found that large number of macroinvertebrates such as Gastropoda and Arachnoidea occurred inside EMAs in the Lake Chivero, Zimbabwe. Moreover, high richness (68 taxa and 96 taxa) and biodiversity of macroinvertebrates associated with root masses of E. crassipes in a coastal lagoon of Mexico and Taabo Lake in Ivory Coast were found by Rocha-Ramirez et al (2007) and Kouamé et al (2010).…”

“…Due to their sensitivity to environmental conditions, they are usually used as an indicator to monitor and assess the environmental pollutions, ecological restorations, and ecological impacts of species invasion (Muotka et al 2002;Vasconcelos and Melo 2008;Archaimbault et al 2010). Previously, studies mainly focused on the epiphytic macroinvertebrate community beneath E. crassipes mats and found that there were a higher abundance and diversity of macroinvertebrates in the area of water hyacinth root systems (Brendonck et al 2003;Rocha-Ramirez et al 2007). Moreover, macroinvertebrates within the root sphere of water hyacinth were the typical benthic species in the same area in Lake Okeechobee (O'Hara 1967).…”

An ecological engineering project with confined growth of 1.5 km 2 of Eichhornia crassipes was implemented to remove pollutants in Lake Dianchi. To assess the ecological effects of this project on benthic macroinvertebrate assemblages, a 1-year investigation at the areas inside and outside E. crassipes mats was conducted from May 2013 to May 2014. All the 10 sampling sites in the areas were grouped into two statistically significant clusters mainly corresponding to inside and outside E. crassipes mat areas (EMAs), by clustering analysis. E. crassipes reduced the densities of pollution indicator taxa (e.g., Oligochaeta and Chironomidae larvae); thus, the total densities of benthic macroinvertebrates at the area inside EMAs (mean 328.2 ind./m 2 ) were slightly lower than that at the area outside EMAs (mean 505.6 ind./m 2 ). Four functional feeding groups including 38 species of benthic macroinvertebrates were collected at the area inside EMAs, while only three functional feeding groups containing 17 species were collected at the area outside EMAs. The biodiversity indices (Shannon-Weiner, Margalef, Simpson, and Peilou
