“…La MOPF fue la categoría alimentaria más frecuente en la mayoría de larvas de Chironomidae, como es comúnmente reportado para este grupo en el ámbito global (Berg, 1995;Henriques-Oliveira et al, 2003;Sanseverino & Nessimian, 2008;Silva et al, 2008;Galizzi et al, 2012). Las algas también han sido reportadas como otro ítem presente en contenidos estomacales de quironómidos de la región Neotropical (Butakka, Ragonha, Train, Pinha, & Takeda, 2016). No obstante, en las lagunas estudiadas su importancia fue menor al 5 % y pese a su relativa alta frecuencia en las dietas, los bajos valores observados podrían corresponder con los esperados por consumo incidental.…”

Tropical high mountain lakes show unique environmental conditions where chironomids play an important role in ecosystem functioning. The characteristics of these environments could favor diet overlap and therefore a high interspecific competition. This study described the dietary habits of chironomid genera, identified whether the dietary habits were specialized or generalist, and analyzed the diet overlap in the genera. Chironomidae larvae were collected from four lakes of the Chingaza paramo during the dry season, between April and May of 2 016. The feeding habits of larvae were evaluated by analyzing gut contents following standard methods. Each genus was assigned to trophic guilds (carnivore, detritivore and algivore) and the diet overlap was estimated using the Pinka's index. A total of 1 003 individuals were collected and nine genera were identified. Larvae consumed mainly fine particulate organic matter (FPOM), algae, macrophyte fragments, macroinvertebrates, and animal tissues. FPOM was the main feeding resource of detritivores. The analysis of diets showed a high affinity of each genus for a single trophic guild and most of the genera were generalist in the use of resources. For all lakes, high levels of diet overlap were observed among genera and trophic guilds, mainly among detritivores. Our results suggested that Chironomidae larvae of these lakes presented well differentiated trophic habits, and showed a moderate diet overlap within detritivores and carnivores.

“…Se ha reportado a los quironómidos como un grupo generalista u oportunista (Berg, 1995;Henriques-Oliveira et al, 2003;Sanseverino & Nessimian, 2008;Butakka et al, 2016). Aunque la MOPF constituye la principal fuente de alimento, son capaces de aprovechar otros recursos, por lo que el nivel de especialización esperado es muy bajo.…”

Al respecto, se conoce que la plasticidad de esta familia les permite habitar desde ambientes prístinos hasta ambientes altamente contaminados, así como hábitats de agua dulce o inclusive hipersalinos (Butakka, Ragonha, Train, Pinha, & Takeda, 2016). Sin embargo, en Santa Rosa, los moluscos y oligoquetos no fueron representativos: solamente fueron encontrados Buenoa sp.…”

Coastal wetlands are sensitive ecosystems of high productivity because of the ecosystem services that they provide, like water purification, flood reduction, protection of marine coasts. In addition, coastal wetlands are places of great biological diversity. The objective of the present study was to determine the community structure of the benthic macroinvertebrates in relation to the spatial variations in the littoral zone of the Santa Rosa wetland, Lima, Peru. The study was divided into six bimonthly periods from August 2015 to June 2016, we established eight sampling sites: three sites in the main lagoon, two sites in the lagoon arm and two sites in isolated small pools. We carried out the sampling with a hand net of 250μm mesh aperture with 3 replicas for each site. The 8 sites evaluated were environmentally characterized, the physicochemical parameters of the water were recorded for each sampling site and the variations of the water level of the wetland in each sampling campaign were determined through a wooden post with marks in centimeters. We collected a total of 28655 organisms distributed in 76 species. Diptera and Coleoptera were the orders with greatest richness, with 24 and 19 species respectively. The most abundant species were Buenoa sp. (Hemiptera: Notonectidae), Ischnura sp. (Odonata: Coenagrionidae), Chironomus sp. and Goeldichironomus sp. (Diptera: Chironomidae); these four genera represented 62.43% of the total abundance. In the spatial variation, most sites shared the same structure and composition of macroinvertebrates; this was expected because they are connected to the main water body temporarily or permanently, which consequently gives them greater stability and resilience. Only the sites with less depth and extension on the one side and scarce aquatic vegetation and anthropogenic impact on the other side were separated from the general set. Despite the variety of impacts that the wetland suffers, it was observed that the deeper and more vegetated sites are more resilient than the areas exposed to impact and with less water and vegetation. On the other hand, the physicochemical parameters of water at one site (E1) differentiate the community in the absence of impact.

Changes in feeding selectivity of freshwater invertebrates across a natural thermal gradient

et al. 2018

Environmental warming places physiological constraints on organisms, which may be mitigated by their feeding behavior. Theory predicts that consumers should increase their feeding selectivity for more energetically valuable resources in warmer environments to offset the disproportionate increase in metabolic demand relative to ingestion rate. This may also result in a change in feeding strategy or a shift towards a more specialist diet. This study used a natural warming experiment to investigate temperature effects on the feeding selectivity of three freshwater invertebrate grazers: the snail Radix balthica, the blackfly larva Simulium aureum, and the midgefly larva Eukiefferiella minor. Chesson’s Selectivity Index was used to compare the proportional abundance of diatom species in the guts of each invertebrate species with corresponding rock biofilms sampled from streams of different temperature. The snails became more selective in warmer streams, choosing high profile epilithic diatoms over other guilds and feeding on a lower diversity of diatom species. The blackfly larvae appeared to switch from active collector gathering of sessile high profile diatoms to more passive filter feeding of motile diatoms in warmer streams. No changes in selectivity were observed for the midgefly larvae, whose diet was representative of resource availability in the environment. These results suggest that key primary consumers in freshwater streams, which constitute a major portion of invertebrate biomass, can change their feeding behavior in warmer waters in a range of different ways. These patterns could potentially lead to fundamental changes in the flow of energy through freshwater food webs.
