Environmental differences occur between lentic and lotic communities' establishment, especially because of water time residence. Here we used a combination of field measurements and statistical analysis to evaluate the influent factors on the aquatic macroinvertebrates' composition and structure in 15 anthropogenic lakes from Alto Iguaçu's region. Macroinvertebrates were sampled from the marginal vegetation (with or without macrophytes) and sediment. Chemical parameters ranged among the anthropogenic lakes, mainly those which are connected to the Iguaçu River, beyond the presence or absence of macrophytes, interfering on the community's structure. Lake's morphometric data were measured in each lake and its relation to community was tested. The community...
