“…La granulometría del sustrato y la velocidad de la corriente son factores que afectan la distribución de los quironómidos (lenCioni & rossaro, 2005;PrinCiPe et al, 2008) y pueden actuar conjuntamente para determinar sus preferencias de hábitat (sanseverino & nessiMian, 1998). Asimismo, las variaciones estacionales han sido atribuidas al voltinismo y al efecto de la temperatura sobre ciclos de vida de las poblaciones (Cortes, 1992).…”

Chironomidae es una de las familias más abundantes y diversas en los ecosistemas de agua dulce, sin embargo su complejidad sistemática ha sido motivo de su escaso desarrollo en muchos estudios limnológicos. El objetivo de este estudio fue analizar los ensambles de Chironomidae bentónicos y derivantes de un arroyo serrano de la región central de Argentina evaluando abundancia, diversidad y composición de especies en diferentes hábitats fluviales y distintas estaciones del año. Se tomaron muestras cuantitativas de bentos y deriva en el arroyo Achiras (Córdoba, Argentina) en hábitats de rabión y corredera, y se registraron variables ambientales en las cuatro estaciones del año, entre 2007 y 2008. Se registró un total de 25 taxones pertenecientes a cuatro subfamilias. Los quironómidos bentónicos constituyeron el 19% de la comunidad de macroinvertebrados, mientras que en deriva representaron el 33%. En el bentos dominó Thienemannimyia sp. y en la deriva, Corynoneura sp. De acuerdo con los resultados de ANOVAs de dos vías, los mayores valores de riqueza taxonómica y densidad bentónica se registraron en el periodo de aguas bajas (otoño e invierno) y la diversidad de quirónomidos bentónicos fue mayor en rabión. Por el contrario, para el ensamble de derivantes sólo la equitatividad fue diferente entre hábitats y entre estaciones. El análisis TWINSPAN mostró una separación espacio-temporal de las muestras de bentos, mientras que las muestras de deriva se segregaron sólo temporalmente lo que sugiere que el transporte aguas abajo de los invertebrados homogeniza la variación espacial observada en el bentos. La densidad de bentos y deriva varió de manera similar a través de las estaciones del año y el coeficiente de Jaccard presentó un alto índice de similitud entre bentos y deriva (86%). Este trabajo posibilitó conocer la dinámica temporal y espacial de los quironómidos bentónicos y derivantes en un arroyo serrano. La ampliación del conocimiento taxonómico, biológico y ecológico de Chironomidae posibilitará adecuar e implementar estrategias de manejo y conservación de los ecosistemas lóticos en la región central de Argentina.

“…Benthic invertebrates are functionally important for food webs, composing the basal resources that are transferred to higher trophic levels (Cummins, 1973;Sanseverino and Nessimian, 2008). In Neotropical floodplains, the benthic community is represented predominantly by Chironomidae larvae (Higuti and Takeda, 2002;Higuti, 2004), which play an important role in food webs of freshwater ecosystems, representing the major link between producers and consumers (Tokeshi, 1995;Walther et al, 2006).…”

“…Studies about Chironomidae feeding habits indicated the importance of quality and quantity of the available food resources (e.g., algae, detritus, plant fragments, decomposing wood, fungi and invertebrates) that are used by the species in different habitat types (Henriques-Oliveira et al, 2003;Sanseverino and Nessimian, 2008). Consequently, Chironomidae diet studies are essential for a better understanding of how these insect explore its habitats (Ingvason et al, 2004;Walther et al, 2006;Mokany et al, 2008).…”

Chironomidae feeding habits in different habitats from a Neotropical floodplain: exploring patterns in aquatic food webs

et al. 2016

Ecological studies on food webs have considerably increased in recent decades, especially in aquatic communities. Because Chironomidae family are highly specious, occurring in almost all aquatic habitats is considered organisms-key to initiate studies on ecological relationships and trophic webs. We tested the hypothesis that the diversity of the morphospecies diet reflects differences on both the food items available among habitats and the preferences of larval feeding. We analyzed the gut content of the seven most abundant Chironomidae morphospecies of the different habitats from the Upper Paraná River. We categorized the food items found into algae, fungal spores, fragments of plants, algae and animal fragments and sponge spicules. We observed the algae predominance in the gut content of morphospecies from lakes. Considering the different regions from each lake, we registered the highest food abundance in the littoral regions in relation to the central regions. From the variety of feeding habits (number of item kinds), we classified Chironomus strenzkei, Tanytarsus sp.1, Procladius sp.1 as generalist morphospecies. We found a nested pattern between food items and Chironomidae morphospecies, where some items were common to all taxa (e.g., Bacillariophyceae algae, especially), while others were found in specific morphospecies (e.g., animals fragments found in Procladius sp.1). The algae represented the most percentage of gut contents of Chironomidae larvae. This was especially true for the individuals from littoral regions, which is probably due to the major densities of algae associated to macrophytes, which are abundant in these regions. Therefore, the feeding behavior of these morphospecies was generalist and not selective, depending only of the available resources.Keywords: lakes, food networks, aquatic invertebrate, food resources, Upper Paraná River. Hábitos alimentares de Chironomidae em diferentes habitats de uma planície de inundação Neotropical: explorando padrões em redes alimentares aquáticas ResumoEstudos sobre redes alimentares têm aumentado consideravelmente nas últimas décadas em pesquisas de ecologia, principalmente em comunidades aquáticas. Em função Família Chironomidae ser altamente especiosa, ocorrendo em quase todos os hábitats aquáticos, é considerada como organismos-chave para estudos preliminares sobre as relações ecológicas como redes tróficas. Nós testamos a hipótese de que a diversidade de dietas das morfoespécies reflete diferenças tanto na disponibilidade dos itens alimentares entre os hábitats analisados, quanto preferencias alimentares das larvas. Nós analisamos o conteúdo digestivo das sete morfoespécies mais abundantes de diferentes habitats da planície de inundação do alto rio Paraná. Nós categorizamos os itens alimentares encontrados como algas, esporos de fungos, fragmentos vegetais, fragmentos de algas ou de animais e espículas de esponjas. Nós observamos a predominância de algas no conteúdo digestivo das morfoespécies lacustres. Considerando as diferentes regiões d...

“…The analysis of the digestive content in this study confirms this. These authors found that generalist species and opportunists do not exercise pressure on only one food item (Sanseverino and Nessimian, 2008), but rather have an impact on various food items, confirming that the majority of chironomids are generalists.…”

“…In freshwaters of Brazil, the importance of aquatic invertebrates, especially Chironomidae, has often been demonstrated and some research has been done to understand their distribution in running water ecosystems (Trivinho-Strixino et al, 2000;Higuti and Takeda, 2002), ecological (Sanseverino and Nessimian, 2001;Henriques-Oliveira et al, 2003;Sanseverino and Nessimian, 2008) and taxonomic aspects (Trivinho- Strixino and Sanseverino, 2003;Roque and Trivinho-Strixino, 2003).…”

Benthic habitats are linked by physical processes and are essential elements in assessing of the distribution dynamics of Chironomidae dipteran insects and their role in aquatic ecosystems. This work presents results of distribution patterns of chironomids larvae in 38 sites that are abundant in the study site, inhabiting the substrate of the main river channel, rapids, tributary brook, floodplain lakes and reservoir along the Sepotuba River from its mouth at the Paraguay River to the headwater region. A total of 1,247 larvae was registered. The most abundant taxa were Polypedilum (Tripodura) sp. (25.2%), Cricotopus sp.3 (23.0%) and Tanytarsus sp. (15.0%). Fissimentum desiccatum were found only in the reservoir; Fissimentum sp.2 and Tanytarsus cf. T. obiriciae sp.2 in floodplain lakes, and Goeldichironomus sp. in the main channel. The low diversity of the sites S06 and S35 is caused by the near-exclusive presence of the species Cricotopus sp.3, alone or together with one or another taxon (Tanytarsus sp., Djalmabatista sp.3). Collectors-filterers represent 16%, collectors-gatherers 15%, predators 11% and scrapers only 1%. The predators dominated in the secondary channel (±88 ind/m 2 ), corresponding to 40% of the total of this group. Cryptochironomus sp.2 (34%) and Ablasbemyia gr. annulata (26%) were the most abundant among the predators. The differences along the river course are decisive for the formation of distinct or discontinuous communities and the limits become obvious though the interrelations between the populations in the community, as for instance, competition for food and habitats.Keywords: Chironomidae, functional trophic groups, diversity, Pantanal of Mato Grosso, floodplains.
