Abstract: ABSTRACT. Structure and composition of Trichoptera (Insecta) community in streams and wetlands of Suiá-Miçú River Basin, Mato Grosso, Brazil. The composition, abundance and species diversity of Trichoptera immatures was studied in 12 tributaries of Suiá-Miçú River Basin, a mosaic of wetlands, streams and rivers tributary of the Xingu River in the Cerrado-Amazonian Forest transition zone in Mato Grosso, Brazil. The varying sizes, flow types and conservation levels of the tributaries were sampled through three p… Show more

“…Our results about the influence of environmental variables on the species richness and abundance support the findings of other studies with different aquatic insects (Nessimian et al, 2008;Dias-Silva et al, 2010;Nogueira et al, 2011). This result could be due to: (i) each water chemistry variable may have not significant relationships with community structure , and (ii) the larvae of aquatic insects can tolerate the wide variation in water chemistry , since Cerrado streams face prolonged dry and rainy seasons, with multiple flood pulses in the latter.…”

“…A Bacia do Suiá-Missu abriga trechos ainda preservados de tipos vegetacionais distintos, que segundo RatteR et al (1978) merecem destaques as fisionomias de cerrado sensu stricto, áreas de Mata Seca e cerrado transicional denominado "cerradão de Hirtella glandulosa" em função da intrigante dominância desta espécie na região (RatteR et al 1973;Cabette et al 2010;shiMano et al 2010;noGueiRa et al 2011). Em cada ponto, as amostragens consistiram na contagem visual do número de indivíduos adultos das espécies de Odonata e na coleta de espécimes para confirmação de identificação com auxílio de rede entomológica (puçá).…”

“…They were also among the most abundant taxa found in this study and have been pointed out as bioindicators of pristine environments. These organisms could be strongly affected in severely impacted streams of Cerrado (Nogueira et al 2011;Pereira et al 2012) and Amazonian biomes (Couceiro et al 2009). Since shredder insects are abundant and ubiquitously found in headwaters, changes in their local abundance could be a strong candidate to monitor RIL impacts on stream communities.…”
