FILO ARTHROPODA CLASSE INSECTA PDF

E-mail: rmkikuchi yahoo. The distribution pattern of aquatic organisms results from the interaction of the habit, the physical conditions of the habitat substrate, flow, turbulence and the food availability. The purpose of this study is to know the composition and to understand the pattern of distribution of the animal community of a tropical stream. When analyzed the occurrence in different types of substrate - vegetal, rocky and sandy - we found a larger density in the rocky substrate and larger diversity in the vegetal substrate. In the three substrata, the invertebrates of the class Insecta, and mainly the order Diptera, prevailed in abundance and diversity of species.

E-mail: rmkikuchi yahoo. The distribution pattern of aquatic organisms results from the interaction of the habit, the physical conditions of the habitat substrate, flow, turbulence and the food availability. The purpose of this study is to know the composition and to understand the pattern of distribution of the animal community of a tropical stream. When analyzed the occurrence in different types of substrate - vegetal, rocky and sandy - we found a larger density in the rocky substrate and larger diversity in the vegetal substrate.

In the three substrata, the invertebrates of the class Insecta, and mainly the order Diptera, prevailed in abundance and diversity of species. Of this order, in the vegetal and rocky substrate prevailed the families Chironomidae and Simuliidae and in the sediment, the family Chironomidae.

Between the Chironomidae was found several genera, with many individuals, of the subfamily Ortocladiinae. Key words: Macroinvertebrates, lotic environment, distribution, substrate, ordination. Em geral, pedras grandes constituem um substrato mais complexo, com uma fauna de invertebrados mais diversa. Um total de seis coletas durante o ano foram realizadas, a intervalos de dois meses cada, perfazendo 18 amostras por substrato. Para o sedimento, o volume foi o do frasco utilizado na coleta cm 3.
