Última Integridade da paisagem e sua influência sobre a composição da comunidade de Chironomidae (Diptera) em riachos de pequena ordem Ecología austral De Toni,Kamila R; Nava,Diane; Restello,Rozane M.; Decian,Vanderlei; Rovani,Ivan L.; Hepp,Luiz U.. Trabalhos com ecologia de riachos tem buscado compreender os padrões de distribuição das comunidades aquáticas procurando responder de que forma os fatores locais e regionais, infuenciam na ocorrência e persistência de determinadas espécies nesses ecossistemas. Este estudo investigou a infuência dos usos e ocupação da terra sobre a comunidade de Chironomidae em riachos em duas áreas de drenagem no sul do Brasil. Larvas de Chironomidae foram coletadas em riachos de 1a e 2a ordens. A zona ripária dos riachos (30 m em ambas as margens) teve sua paisagem analisada utilizando técnicas de geoprocessamento e diferentes usos e ocupação da terra foram classifcados e quantifcados. Os usos e ocupação da terra foram diferentes entre as duas áreas de drenagem...

Zool. Hepp,Luiz U.; Milesi,Silvia V.; Nava,Diane; Restello,Rozane M.. ABSTRACT Stream insects use in different ways the stream habitats which affect patterns of species occurrence on stream. The nestedness is one of these patterns being an ecological mechanism that generates beta diversity. In this study, we verify the effects of temporal environmental variations on nestedness patterns of Chironomidae assemblages on subtropical streams. We collected chironomid larvae during winter and summer during three years (2010, 2011 and 2012) in Brazilian Subtropical low-order streams (Erechim, state of Rio Grande do Sul, Brazil). We measured environmental variables in each stream. To assess if assemblages will show nested patterns intra- and interannual we used a NODF metric. We observed nestedness only in one year, this pattern was... Tipo: Info:eu-repo/semantics/article Palavras-chave: Atlantic forest streams; Beta-diversity; Chironomidae; Climate changes; Conservation.

Bras. Zool. Nava,Diane; Restello,Rozane M.; Hepp,Luiz U.. The structure and composition of stream benthic communities are strongly influenced by spatial and temporal factors. This study evaluated the intra and inter-annual variations in Chironomidae communities in subtropical streams. The organisms were sampled from 10 small-order streams during the summer and winter of 2010-2012. The number of chironomid specimens sampled was 7,568, distributed in 49 genera. Chironomid abundance and richness varied intra and inter-annually and community composition varied intra-annually (2010 and 2011). Water temperature, total organic carbon, nitrogen, and rainfall were correlated with chironomid community composition. The intra-annual variation of the community was dependent on climatic variations (temperature and rainfall)...

Bras. Zool. Deliberalli,Wanessa; Cansian,Rogério L.; Pereira,Albanin A. M.; Loureiro,Rafael C.; Hepp,Luiz U.; Restello,Rozane M.. ABSTRACT Streams in urban areas are strongly impacted by the input of organic matter and metals, for instance copper (Cu) and zinc (Zn). These metals are essential for the aquatic biota, but when absorbed in excess they are toxic. In Chiro nomidae larvae, the deleterious effects of heavy metals can be ascertained by analyzing the morphological deformities of the larval mentum, a structure of the oral cavity. In this study, we evaluated I) the bioavailability of Cu and Zn in urban stream sediments and II) the relationship between Cu and Zn concentrations and the incidence of deformities in the mentum of Chironomus larvae. Chironomid flies were collected from four locations in two streams at an urban area in southern Brazil. They were identified and the...

Bras. Zool. Hepp,Luiz Ubiratan; Milesi,Silvia V.; Biasi,Cristiane; Restello,Rozane M.. This study evaluates the effects of agricultural and urban activities on the structure and composition of benthic communities of streams in the state of Rio Grande do Sul, Brazil. Benthic macroinvertebrates were collected in streams influenced by urbanization and agriculture and in streams with no anthropogenic disturbances (reference streams). Organism density was superior in urban streams when compared with streams in the other two areas. The taxonomic richness and Shannon diversity index were higher in reference streams. The benthic fauna composition was significantly different among land uses. The classification and ordination analyses corroborated the results of variance analyses demonstrating the formation of clusters corresponding to streams with...
