“…We expected the lower current speed and greater accumulation of organic litter in pools to favor colonization by Chironomidae larvae, as suggested by others in streams running through remnant Atlantic Forest regions in Brazil (Sanseverino & Nessimian 2001, Henriques-Oliveira et al 2003a, Gurski et al 2014. On the contrary, we found greater richness in riffles.…”

“…These differences probably occurred mainly due to the water speed, since the litter composition was similar between the mesohabitats and among the streams (low levels of R from Anosim). Gurski et al (2014) reported a tendency for distinction of the composition of assemblages of Chironomidae in function of the current speed in riffles and pools but not of the substrate (litter and sediment). In contrast, Rosa et al (2011) found that the composition of larvae was the only community attribute that differed between riffles and pools and that this difference occurred in function of the type of substrate of each mesohabitat (litter and sediment).…”

Studies on mesohabitat scale have been used to shed light on the ecology and distribution of chironomid larvae in small streams. Thus, the objective of the present study was to examine the diversity and distribution of the Chironomidae assemblage on the mesohabitat scale in three streams located in different preserved areas of southeastern Brazil. In each stream, litter samples were obtained in the dry season of 2010 in ten pools and ten riffles with a Surber sampler (area 0.04 m(2); mesh size 0.21 mm). The abundance was similar among streams and between mesohabitats, while the estimated richness was highest in riffles. There was a difference in the composition of the Chironomidae assemblages between the mesohabitats, although the litter composition was similar between them, indicating the importance of current speed on the distribution of the taxa. The dispersion of the sample units (β-diversity) of riffles and pools was similar, although it was different among the three streams. The results of this study provide further evidence of the importance of habitat heterogeneity within streams as a generator of diversity for Chironomidae in tropical lotic systems.

“…Such characteristics may have contributed to the greater variability of genera occurrence of this family, with diverse ecological requirements and wide distribution (Amorim et al 2004;Brown 2007). However, in the altered streams, the chironomid assembly composition has probably consisted of a few tolerant genera distributed in large densities, as evidenced by Gurski et al (2014) in a study conducted in the same streams, which may have collaborated on the pattern of abundance observed in the present study.…”

A��. The benthic macroinvertebrate community structure is directly related to environmental factors such as water characteristics, habitat availability and substrate heterogeneity. This study had the purpose of characterizing the benthic macroinvertebrate community and compare its a�ributes in streams located inside (preserved area) and outside (altered area) the Iguaçu National Park, in the west of Parana, Brazil, in two season (dry and rainy). Three replicates per site were obtained through the Surber collector in four microhabitats (li�er pool, li�er riffle, substrate pool and substrate riffle). There was significant discrimination in the benthic fauna composition among the study areas (Wilks=0.091; F 272,746 = 2.249; P<0.0001). The taxa Corbiculidae, Hyalellidae and Trichodactylidae characterized the Macuco Stream; Talitridae, Libellulidae and Naucoridae characterized Poço Preto and Dourado stream; Oligoneuridae, Leptoceridae and Hydropsychidae characterized Apepu stream, and Tubificidae, Corduliidae and Elmidae were grouped in Tamanduá stream. Significant differences were observed in the mean density and richness (P<0.05) among the streams from both preserved and altered areas, with the highest richness recorded in the preserved area and li�er pool microhabitat. The RDA Analysis separated the streams and organisms according to the environmental variables. The a�ribute differences were related to the preservation conditions of the riparian forest, whose presence in the preserved streams provided greater diversity of habitats and contributed to the presence of organisms on the substrate. On the other hand, several of impacts a�ributed to the agrochemical contaminants, soil disturbation and degradation of the riparian vegetation may be considered as factors which contributed to the differences among the analyzed streams.[Keywords: aquatic macroinvertebrates, Iguaçu National Park, agricultural impact, riparian vegetation, habitat heterogeneity] R��.

La estructura de la comunidad de macroinvertebrados bentónicos está directamente relacionada con factores ambientales tales como las características del agua, la disponibilidad de hábitats y la diversidad de sustratos. El objetivo de este estudio fue caracterizar la comunidad de macroinvertebrados bentónicos y comparar los atributos de esta comunidad en los arroyos internos (zona preservada) y externos (zona alterada) del Parque Nacional Iguazú, al oeste de Paraná, Brasil, en dos períodos estacionales (seco y húmedo). Se tomaron tres repeticiones por sitio, con colector Surber, en cuatro microhábitats (hojas en remanso, hojas en la corriente, sedimentos en remanso y sedimentos en la corriente). Se encontró una discriminación significativa en la composición de la fauna bentónica entre las áreas de estudio (Wilks=0.091; F 272,746 =2.249, P<0.0001). Las taxa Corbiculidae, Hyalellidae y Trichodactylidae caracterizaron al arroyo Macuco; Talitridae, Libellulidae...
