“…For rare genera, the scale of land use was more representative (b 4 rare genera 37.5% p < 0.05) (Fig. However, in other studies conducted in the Cerrado it has not been possible to demonstrate the influence of the physical and chemical characteristics (e.g., conductivity) of water in predicting the composition of the Trichoptera community (Bispo and Oliveira, 1998;Oliveira and Bispo, 2001). This indicates that the environmental differences between land use patterns affect the rare genera more than the common genera.…”

The purpose of this study was to describe the spatial distribution of Trichoptera larvae in an area of fragmented Cerrado. We used additive partitioning for evaluating the most representative scale in terms of beta diversity and identifying differences in the pattern of partitioning between land uses. Four hierarchical levels were considered (substrate type, stream, microbasin, and land use) in five partitions (entire community, common genera, rare genera, livestock activity (LA), and subsistence activity). The most representative scale for the entire community was microbasin (β3 = 25.71%), for rare genera it was land use (β4 = 37.5%) and for common genera it was type of substrate (β1 = 28.75%). The comparison among land uses showed that the presence of LA changed the pattern of the distribution of beta diversity.

“…(Tables 1 and 2). Oliveira et al (1999), Oliveira & Bispo (2001) and Bispo et al (2004) recorded other six genera in Rio das Almas Basin (Atopsyche Banks, Hydroptila Dalman, Atanatolica Mosely, Setodes Rambur, Polycentropus Curtis and Xiphocentron Brauer), that were not resampled during field work, but were considered in the totals for the region. Thus, the actual knowledge about caddisflies is 37 genera (12 families) in Goiás State, Brazil.…”

“…Recent contributions to the knowledge about the Trichoptera diversity reflected an increase in genera recorded in Goiás from five ) to 33 genera (six new records in Oliveira et al (1999), 11 in Oliveira & Bispo (2001), two in Bispo et al (2004), two in Shuvartz et al (2005), six in MartinsSilva et al (2008) and one in Calor (2008a)). However, as pointed by Oliveira & Froehlich (1997), the ecological and taxonomic knowledge about the Trichoptera in Brazilian Savanna Streams is still incipient.…”

“…The larvae were identified to genus according to: Marshal (1979), Wiggins (1996a,b), Oliveira (2006), Morse & Holzenthal (2006), Calor (2008b) and Calor & Froehlich (2008). This paper also considers data from Oliveira et al (1999), Oliveira & Bispo (2001) and Bispo et al (2004) in the total number. Genus preference for a certain microhabitat was analyzed by calculating the relative proportion of observations on the taxon sampling.…”

This paper deals with the Trichoptera immature fauna collected in 101 streams in Rio das Almas Basin during August-October 2008 and in Rio Paranã, Iaciara-GO municipality, on August 2003, using kick-nets with 0.025 m 2 of opening and 2 mm mesh. We record four new genera for Goiás State, expanding records of genera from 33 to 37 and contributing to the Trichoptera fauna knowledge in Central Brazil.

“…Os fragmentadores ocorreram em baixa frequência no riacho Saltinho, sendo os tricópteros considerados como fragmentadores verdadeiros (oliveira & Bispo, 2001;Gonsales et al, 2002;pes, 2002). Triplectides (Trichoptera, Leptoceridae) ocorreu com maior abundância entre os demais fragmentadores, seguido de Polypedillum (Chironomidae).…”

ABSTRACT. Colonization of leaf litter by benthic macroinvertebrates in an Atlantic forest stream from northeast Brazil. The aim of this study was to analyze the colonization of Inga ingoides (Leguminosae) leaves by benthic macroinvertebrates in field experiments. A total of 270 leaf packs, distributed in three stretches, were submerged of similar morphology and physical and chemical parameters of water between February to July 2013, and retrieved after 7, 30, 60, 90 and 120 days. Two treatments were used: colonization and exclusion of benthic macroinvertebrates. The leaf weight loss (%R) was greater to colonization than exclusion of benthic fauna, showing the role of macroinvertebrates in the leaf breakdown. Shredders played a minor role in the leaf breakdown. Filtering was the main trophic feeding group (45.6%), followed by predator (31.2%), collector (11.8%), scrapers (6.7%) and shredders (4.8%). Triplectides (Trichoptera: Leptoceridae), Polypedillum, and Stenochironomus (Diptera, Chironomidae) were the most frequent shredders. KEYWORDS.Benthic fauna, leaf breakdown, protected areas, shredders, stream ecology. RESUMO.O objetivo do estudo foi avaliar a colonização de macroinvertebrados bentônicos em detritos foliares de Inga ingoides (Leguminosae) em experimentos de campo em um riacho de primeira ordem da Mata Atlântica do Estado de Pernambuco no nordeste do Brasil. Um total de 270 bolsas de folhiço, distribuídas em três trechos do riacho com características similares em relação à morfologia e parâmetros físicos e químicos da água foram submersas, entre fevereiro a julho de 2013 e retiradas após 7, 30, 60, 90 e 120 dias. Dois tratamentos foram utilizados: colonização e exclusão da macrofauna. O percentual de biomassa remanescente final (%R) foi maior para bolsas de colonização do que para as de exclusão, evidenciando a efetiva participação dos macroinvertebrados no processo de decomposição. Os fragmentadores apresentaram menor participação no processo de decomposição foliar de I. ingoides, sendo Tripletides (Trichoptera: Leptoceridae), Polypedillum e Stenochironomus (Diptera, Chironomidae) os táxons predominantes na macrofauna. Filtrador foi o grupo trófico funcional predominante (45,6%), seguido por predador (31,2%), coletor (11,8%), raspador (6,7%) e fragmentador (4,8%). PALAVRAS-CHAVE.Decomposição foliar, ecologia de riachos, fauna bentônica, fragmentadores, unidade de conservação.Os macroinvertebrados são importantes para os ecossistemas aquáticos por desempenhar papel fundamental na degradação do material alóctone em riachos, principalmente nas nascentes. São comumente utilizados como ferramenta em Unidades de Conservação, para o monitoramento da qualidade da água, auxiliando na gestão das águas dessas áreas protegidas que atuam como prestadora de serviços ambientais. Assim, os macroinvertebrados podem se configurar como complemento essencial nas análises de água, contribuindo para a avaliação ecológica desses ecossistemas.A decomposição nos corpos d'água como processo ecossistêmico é tão importante como a...
