BIOINDICADORES: UTILIZAÇÃO DE MACRÓFITAS AQUÁTICAS PARA AVALIAÇÃO DE AMBIENTES LACUSTRES

Abstract

Excessive population growth and hence the rampant increase the use of natural resources, triggers a series of environmental impacts and these impacts from human activities on aquatic ecosystems have produced a continuous and relentless deterioration of water. One such impact is the process of eutrophication, which occurs excessive increased toxicity and increased concentration of nutrients, especially phosphorus and nitrogen. This study aimed to present aquatic macrophytes as an important bio-indicator tool for the evaluation of lacustrine environments using a dam in the municipality of Martinópolis, SP. The methodology consisted of photographs and lacustrine environment evaluation in the field for later cataloging and comparison with ideal environments. Species identification followed the proposed classification of families recognized by the classification system The Angiosperm Phylogeny Group - APG III (2009). The results demonstrate that multiple use of the reservoirs is engaged. Thus, it is concluded that the implementation of studies for the indication of macrophytes as bioindicators of water quality is a priority and highly recommended.
