“…Fluctuations in water regimen allow great habitat diversification, i.e. more tolerant species can occupy distinct regions of the drainage area, in addition to changing the limnological characteristics of streams (SHUVART et al 2005, ABURAYA & CALLIL 2007, ROQUE et al 2007. SILVA et al (2014) also observed that Chironomidae diversity was higher during the years when the abiotic charac- (Figs.…”

“…Polypedilum and Rheotanytarsus were the most common organisms in all samples. Studies report that these genera are easily sampled in streams and are reported as cosmopolitan/tolerant (AMORIM et al 2004, MARCHESE et al 2005, ABURAYA & CALLIL 2007. Furthermore, the high density of individuals of Rheotanytarsus is due to their eating habits: they are filter-feeding organisms, consuming exclusively organic matter present in the water (COFFMAN & FERRINGTON 1996).…”

“…Algumas famílias, como a de Chironomidae, predominam em ambientes aquáticos e mesmo durante secas pronunciadas sua oferta não é limitante (Aburaya & Calill 2007). Dessa forma, as larvas aquáticas estão entre os recursos mais consumidos por espécies de peixes em ambientes aquáticos tropicais, como relatado por Costa (1987) e Castro & Casatti (1997).…”

Abstract:This study aimed to evaluate the spatial and temporal variation of the feeding guilds of fish communities of 10 oxbow lakes of the Cuiabá River in the Pantanal. The lagoons were sampled in three periods of the hydrological cycle (beginning and ending of the dry and flooding season of 2005). The feeding guilds were determined through analysis of stomach contents of the most abundant species in the community. Were analyzed 37 species belonging to eight trophic guilds (insectivore, herbivore, omnivore, zooplanktivore, planktivore, detritivore, benthivore and iliophage), whitch varied spatially and temporally. A change in the composition of trophic guilds between the periods and locations was observed, but the number of guilds did not vary for either of them. Our results suggest that spatial and temporal variation in the composition of the guilds can be related to many factors, such as alterations in the composition of the community where new species can contribute to the different trophic guilds; and the exploration of more abundant resources in certain periods of the year favoring the presence of some guilds only in some periods. Keywords: trophic groups, fishes, hydrological cycle, feeding ecology, community structure. Resumo: O presente trabalho teve como objetivo avaliar a variação espacial e temporal das guildas alimentares das comunidades de peixes em 10 lagoas marginais do Rio Cuiabá no Pantanal. As lagoas foram amostradas em três períodos do ciclo hidrológico (início e final da seca e início da enchente de 2005). As guildas alimentares foram determinadas através da análise do conteúdo estomacal das espécies mais abundantes da comunidade. Foram analisadas 37 espécies pertencentes a oito guildas alimentares (insetívora, herbívora, onívora, zooplanctívora, planctívora, detritívora, bentívora e iliófaga), as quais variaram espacial e temporalmente. Observamos uma mudança na composição das guildas tróficas entre os períodos e locais analisados, porém o número de guildas não variou espaço-temporalmente. Nossos resultados sugerem que as mudanças espaciais e temporais na composição das guildas podem estar relacionadas com diversos fatores, como as alterações na composição da comunidade onde novas espécies podem compor as diferentes guildas; a exploração de recursos mais abundantes em determinadas épocas do ano favorecendo a presença de algumas guildas somente em alguns períodos. Palavras-chave: grupos tróficos, peixes, ciclo hidrológico, ecologia alimentar, estrutura de comunidade.

“…In the Paraguay River and its tributaries, Chironomidae larvae are potentially important in the food chain (Wantzen and Junk, 2005) and abundant aquatic insects found in benthic communities (Stur et al, 2000(Stur et al, , 2006Aburaya and Callil, 2007). In this basin, research has been conducted to understand ecological aspects (Da Silva et al, 2001;Wantzen and Junk, 2005), aquatic invertebrates (De Drago et al, 2004;Marchese et al, 2005;Wantzen and Wagner, 2006), and biodiversity (Alho et al, 2003;Junk et al, 2006).…”

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.
