“…As has been pointed out by some authors (NESSIMIAN & SANSEVERINO 1998, NESSIMIAN et al 1999, HENRIQUES-OLIVEIRA et al 2003, MOTTA & UIEDA 2004, this family shows a wide diet variation with genera belonging to different trophic groups. Because of this high diet flexibility it would be necessary to identify Chironomidae larvae until genera level for a correct diet analysis.…”

“…Fine particulate organic matter (FPOM) is the main food item used by chironomids, but always associated with other food resources (HENRIQUES-OLIVEIRA et al 2003, MOTTA & UIEDA 2004, CALLISTO et al 2007, SANSEVERINO & NESSIMIAN 2008, SILVA et al 2008. However, it is important to recognize that chironomids, such as most aquatic insects, are not limited to a single feeding strategy (MOTTA & UIEDA 2004).…”

ABSTRACT. The diet of macroinvertebrates sampled in leaf-bags incubated in a tropical stream was analyzed on a spatial scale (one forested and one deforested area) and on a temporal scale (dry and rainy seasons). The macroinvertebrates were mostly represented by detritivores specialized in fine detritus (69%), followed by generalist detritivores (10% with a diet based on fine and coarse detritus), carnivores (10%), omnivores (8%), and one detritivore genera specialized on coarse detritus (3%). The detritivores exhibited a broad spatial and temporal distribution and were represented mainly by Ephemeroptera, Trichoptera and Diptera. Phylloicus sp. (Trichoptera) consumed mostly coarse detritus (CPOM) and can be classified as the unique specialist shredder in this stream. Carnivores were represented by Anacroneuria sp.

“…In addition, leaf decomposition to fine detritus in warm tropical streams is fast (Mathuriau & Chauvet, 2002;Dobson et al, 2002) and continuous throughout the year. Hence, the occurrence of this food item in the guts contents would be mainly due to its high availability in the habitat (Henriques-Oliveira et al, 2003) rather than to feeding specialization. Indeed, a community dominated by taxa with high affinity Tab.…”

AbstrAct. 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 total density, whereas the proportion of shredders was very low, representing less of 0.5% of total density. Asemblage composition of macroinvertebrates differed between impacted and unimpacted sites. Predators were dominant in taxa number, representing about 60% of total taxa richness. In addition, the diversity and richness of collector-gatherers differed significantly between degraded and unimpacted sites, reflecting the sensitivity of this group to environmental changes and the utility to be used in the assessment of anthropogenic modifications. The results of this study reinforce the idea that riparian corridor management is critical for the distribution of macroinvertebrate assemblages as well as functional organization of lotic streams.KEywords.

Efecto de los impactos antrópicos sobre los ensambles de macroinvertebrados bentónicos en ríos subtropicales de montaña. Las actividades antrópicas han producido modificaciones en el paisaje ripario y el sistema terrestre adyacente, las cuales causan alteraciones en la composición y estructura funcional de los ensambles de macroinvertebrados. Asimismo, el efecto de estos cambios sobre la estructura funcional de macroinvertebrados es difícil de evaluar debido al escaso conocimiento de este parámetro en ríos tropicales. En este estudio se evaluó si sitios degradados y no degradados por impactos antrópicos diferían en la composición de los ensambles y en la densidad, riqueza y diversidad de cada grupo funcional. La selección de los sitios se relacionó con su calidad riparia, de acuerdo con el índice QBRy. Colectores-recolectores fue el grupo funcional dominante, comprendiendo el 91% de la densidad total, mientras que la proporción de trituradores fue muy baja, representando menos del 0.5% de la densidad total. La composición de los ensambles de macroinvertebrados difirió significativamente entre sitios degradados y de buena calidad riparia. Los predadores fueron dominantes en número de taxones, representando alrededor del 60% de la riqueza de taxones. La diversidad y riqueza de collectores-recolectores fue menor en sitios degradados, reflejando la sensibilidad de este grupo frente a cambios antrópicos. Los resulta...

“…The production of detritus is more intense in tropical lentic ecosystems, which are characterized by high temperatures and high availability of nutrients (Bianchini 2007). A large amount of detritus is consumed by larvae of the family Chironomidae (Henriques-Oliveira et al 2003;Silveira et al 2013;Saito and Fonseca-Gessner 2014), which consists mostly of omnivorous species (Berg 1995;Galizzi et al 2012).…”

Chironomidae stand out among aquatic insects associated with organic matter decomposition due to their abundance, cosmopolitan distribution, the varied forms in which they use detritus, as well as the feeding plasticity of their larvae. The objective of this study was to investigate the structure and composition of the Chironomidae community (Diptera) in the decomposition of Eichhornia azurea leaves in a marginal lake. The working hypothesis is that the taxonomic and functional density and richness of Chironomidae increase over time during the degradation of E. azurea leaves. Decomposition was analyzed in leaves kept in 2-mm mesh litter bags and collected at set successive sampling intervals. Significant differences were found in Chironomidae density and composition in the time scale. The density of individuals increased significantly during the experiment, in contrast to the taxonomic and functional richness. Subfamily Chironominae was the most representative in terms of density and taxonomic richness. The densities of taxa Labrundinia sp., Tanytarsus sp., Dicrotendipes sp., Endotribelos sp. Chironomus sp. and Ablabesmyia sp. were mainly responsible for intragroup similarity in the groups formed at each sampling time. In contrast, the taxonomic composition varied throughout the experiment with characteristic ecologic succession and dynamic stabilization of the colonizing community towards the end of the experiment. In conclusion, the Chironomidae community structure presented an increase in larva density during the experimental period associated with changes in taxon composition; however, the total taxonomic richness variation was low and functional richness did not vary.
