Última Composition and diversity of benthic macroinvertebrates in a Brazilian Cerrado stream Iheringia, Sér. Zool. Pio,Jéssica F. G.; Santiago,Eunice de F. E.; Copatti,Carlos E.. ABSTRACT This study aimed to analyse the diversity and composition of benthic macroinvertebrate assemblages in the dry and rainy seasons in a Brazilian Cerrado stream, where it was hypothesized that the dry season has higher diversity and it differs in terms of organism composition in relation to the rainy season. Sampling was carried out in the dry (May and August/2016 and August/2017) and rainy seasons (November/2016 and February and November/2017). Individuals were identified at the family level and classified according to functional feeding group (FFG). There were 3,776 individuals, in which Chironomidae was the most abundant taxon with 2,226 organisms. The FFG with the highest number of individuals and species richness were collector-gatherer and...

Acta Amazonica SHIMANO,Yulie; CARDOSO,Mylena; JUEN,Leandro. ABSTRACT The present study evaluated the potential for the reduction of sampling effort in studies of ephemeropteran nymphs in Brazilian Amazon streams, Pará State, Brazil, without the loss of ecological information (species composition, abundance, and richness), and the congruence of different levels of taxonomic resolution (morphospecies, genus, family and functional group). Test groups of 15, 10 and five subsamples were selected from the 20 subsamples collected per stream (40 streams sampled), and were compared in terms of their species richness and abundance (ANOVA), and composition (Procrustes). Taxonomic resolution was also analyzed in Procrustes. Species abundance (F(3, 156) = 25.426; p < 0.001) and richness (F(3, 156) = 13.866, p < 0.001)...
