Colonização por macroinvertebrados bentônicos em substrato artificial e natural em um riacho da serra de Itatinga, São Paulo, Brasil

Abstract: Substratos artificial e natural foram comparados quanto ao processo de colonização por macroinvertebrados. No 1º, 3º, 7º, 13º, 21º, 31º e 42º dias de amostragem a riqueza e a abundância dos macroinvertebrados foi analisada. Larvas de Chironomidae foi o grupo mais abundante nos dois substratos durante todo o período amostral (53% em cada substrato), seguido por Oligochaeta (17 no artificial e 18 % no natural), formas imaturas de Ephemeroptera (16 e 11%) e Trichoptera (10 e 11%). O processo de sucessão ecológica… Show more

“…It is important to recognize that leaves can protect and influence the availability of trophic resources for benthic macroinvertebrates (CALLISTO et al 2001, CRISCI-BISPO et al 2007. A benthic community similar to that of the present work was also found by CARVALHO & UIEDA (2004, CARVALHO et al (2008) and RIBEIRO & UIEDA (2005) that analyzed the benthic macroinvertebrates associated to the rocky substratum of the Ribeirão da Quinta stream. In this sense, it may be over-simplistic to assume that all invertebrates collected from litter are feeding specifically on the leaves (BOULTON & BOON 1991).…”

“…Several recent papers have demonstrated that invertebrates associated to leaves may use them as food resource and/ or shelter (CARVALHO & UIEDA 2004, RIBEIRO & UIEDA 2005, CRISCI-BISPO et al 2007. It is important to recognize that leaves can protect and influence the availability of trophic resources for benthic macroinvertebrates (CALLISTO et al 2001, CRISCI-BISPO et al 2007.…”

“…The increased rainfall and consequent faster flow in the wet season is one of the main factors causing variation in the structure of benthic communities in tropical streams (Ribeiro and Uieda, 2005;Carvalho and Uieda, 2004;Battistoni et al, 2010). Our results, however, indicate that only the rich taxa (Enchytraeidae) were vulnerable to increased precipitation.…”

“…This is because, litter from riparian vegetation is a primary source of coarse particulate organic matter (CPOM) to aquatic systems (Carvalho and Uieda, 2004). However, in low-gradient Coastal Plain streams much of the CPOM becomes buried within the sandy stream beds following floods (Smith and Brumsickle, 1989).…”
