Última Effects of anthropogenic impacts on benthic macroinvertebrates assemblages in subtropical mountain streams Iheringia, Sér. Zool. Mesa,Leticia M.; Reynaga,María Celina; Correa,Marcela del V.; Sirombra,Martín G.. The nature of the riparian and surrounding landscape has been modified by anthropogenic activities, which may subsequently alter the composition and functional structure of macroinvertebrate assemblages. The effect of these changes on function of benthic fauna is difficult to assess due to the scarce knowledge on functional structures in tropical streams. In this study we evaluate whether sites impacted and unimpacted by anthropogenic alterations differed in assemblage composition and density, richness and diversity of each functional feeding group. The selection of the sites was related to their distinct riparian characteristics, following the QBRy riparian quality index. Collector-gatherer was the dominant functional feeding group, comprising 91% of...

Iheringia, Sér. Zool. Kiffer Jr.,Walace P.; Giuberti,Thaís Z.; Serpa,Karoline V.; Mendes,Flávio; Moretti,Marcelo S.. ABSTRACT: We evaluated the growth of periphyton and colonization of sterilized cobbles by invertebrates in three coastal streams of the Atlantic Forest (Southeast Brazil) that differ in the conservation level of riparian zones. Because of differences in light availability and water temperature, we hypothesized the growth of periphytic algae would be higher in the most altered stream. Consequently, invertebrate assemblages would differ among streams. Cobbles with similar sizes were ashed and incubated for 7, 15, 30, 45 and 60 days in the studied streams. Despite periphyton growth was faster in the most altered stream, contents of chlorophyll-a did not differ among streams. A total of 954 individuals (98% insects) belonging to 36 taxa was found. Invertebrate... Tipo: Info:eu-repo/semantics/article Palavras-chave: Periphytic biomass; Invertebrate assemblages; Exposed substrates; Anthropogenic changes; Tropical streams.
