Chironomidae larvae (Diptera) of Neotropical floodplain: overlap niche in different habitats

Abstract: The niche overlap between trophic groups of Chironomidae larvae in different habitats was observed between trophic groups and between different environments in Neotropical floodplain. For the evaluation we used the index of niche overlap (C XY ) and analysis of trophic networks, both from the types and amount of food items identified in the larval alimentary canal. In all environments, the larvae fed on mainly organic matter such as plants fragments and algae, but there were many omnivore larvae. Species that … Show more

“…Indeed, this genus is classified as a predator in temperate regions but in this study we classified it as omnivorous. Some diet analysis concluded that, under certain conditions, species of Chironomidae may utilize a wider range of trophic resources (Baker & McLachlan, 1979;Motta & Uieda, 2004;Galizzi et al, 2012;Saito & FonsecaGessner, 2014;Butakka et al 2014). Our results pointed out that, because of its wide trophic spectrum, Monopelopia sp.…”

“…Some common Amazonian Chironomidae larvae build protective tunnels and use different kinds of benthic microhabitats (e.g. sandy bottom, mud with abundant organic matter, streambed with gravel; Butakka et al, 2014) and Ceratopogonidae larvae display different behaviors like sand burying (Leptoconopinae), association to the bottom litter (Forcipomyiinae) or to the streambed (Dasyheleinae) (Ferreira-Kepler et al, 2014). Therefore, even if fish prey upon dipterans of the same families, it does not mean that there is no trophic segregation among fish because they might search for dipteran species that occupy different microhabitats in these streams.…”

“…Most Chironomidae and Ceratopogonidae larvae are, at least partially, detritivores (Butakka et al, 2014), thus playing an essential functional role in aquatic systems converting low quality organic matter into high-quality matter that can be assimilated by other species in the aquatic food web. Thus, the high consumption of these larvae by G. rondoni and G. coropinae includes both in the detritivory food chain.…”

“…Un aspecto final a considerar es que, en los estudios sobre macroinvertebrados bentónicos, la información sobre sus depredadores y el espectro trófico disponible para su alimentación es muy útil (e. g., Barnden 2005, Galizzi et al 2012, Butakka et al 2014). Los hábitos de las larvas de Chironomidae (principalmente detritívoras/sedimentívoras), presuponen un solo grupo funcional con alimento permanente en el meandro del río Bogotá, lo que también favorecería allí el desarrollo del ensamble de esa familia.…”

“…Los hábitos de las larvas de Chironomidae (principalmente detritívoras/sedimentívoras), presuponen un solo grupo funcional con alimento permanente en el meandro del río Bogotá, lo que también favorecería allí el desarrollo del ensamble de esa familia. Esta asunción requiere comprobarse llevando las identificaciones a género y especie, en vista de las diferentes preferencias alimentarias y superposición de nicho entre los grupos tróficos de las larvas de Chironomidae en diferentes hábitats, como se ha comprobado en la llanura de inundación de varios ecosistemas neotropicales (Butakka et al 2014).…”
