“…The macroinvertebrate taxa were classified as gathering collectors, filtering collectors, shredders, scrapers, or predators following specialized literature (Cummins, Merritt, & Andrade, ; Ramirez & Guitiérrez, ; Tomanova, Goitia, & Helešic, ). We estimated dry‐mass biomass instead of abundance to calculate the FFGs because it presents a more accurate picture of the functional structure of the benthic macroinvertebrate assemblages (Jiang, Xiong, Xie, & Chen, ; Rivera‐Usme, Pinilla, Rangel‐Churio, Castro, & Camacho‐Pinzón, ). To do so, each individual of each taxon, up to 50, was photographed in a stereomicroscope (model Leica M80) equipped with a digital camera (model Leica IC 80 HD).…”

Hydropower dams substantially modify lotic ecosystems. Most studies regarding their ecological impacts are based on large dams and provide little information about the far more abundant effects of small hydropower dams. Our aim was to characterize the ecological effects of a small hydropower dam and run-of-the-river reservoir on the structure of benthic macroinvertebrate assemblages in the Pandeiros River located in the neotropical savanna of Brazil. We tested the hypothesis that benthic macroinvertebrate assemblages in sites directly affected by the dam and reservoir would show a different taxonomic structure compared with those in free-flowing sites. We expected to find sensitive native species associated with the free-flowing sites, whereas resistant and non-native invasive taxa were expected in impounded sites. We also explored associations between the presence of native and nonnative invasive taxa to each habitat type. We found that the structure of benthic macroinvertebrate assemblages was significantly different between free-flowing and impounded sites. Also, we found that the dam and reservoir facilitated colonization of non-native invasive species (Corbicula fluminea and Melanoides tuberculata) because only in those sites they were found in high abundance, in contrast to the free-flowing sites. Although the environmental conditions imposed by the impoundment altered the structure of benthic macroinvertebrate assemblages, the effects were limited to sites closest to the dam. Our results highlight the necessity of understanding physical habitat changes caused by the presence and management of run-of-the-river dams and reservoirs.

“…Por otro lado, el presente estudio mostró la mayor abundancia y riqueza de algunos órdenes (Diptera, Coleoptera y Hemiptera) y familias (Chironomidae, Ephydridae, Dytiscidae e Hydrophilidae), los cuales ya se han reportados como característicos de ambientes lénticos tanto en áreas del hemisferio norte como en la región neotropical. Por tanto, el estudio de este pequeño humedal en el desierto costero de Perú confirma la adaptación de estos taxa a ambientes acuáticos con escaso flujo e hidrófitos como principal fuente de materia orgánica (Würdig, Cenzano, & Motta-Marques, 2007;Scheibler & Ciocco, 2013;Peralta & Huamantinco, 2014;Perez-Bilbao, Benetti, & Garrido, 2014;Rivera-Usme, Pinilla, Rangel-Churio, Castro, & Camacho-Pinzón, 2015).…”

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.

Se determinó la calidad del agua en la Ciénaga Mata de Palma, utilizando macroinvertebrados acuáticos como bioindicadores y aplicando el índice BMWP/Col, índices ecológicos de Shannon, Simpson, Margalef y Pielou, con el objetivo de evaluar la calidad del agua y poder implementar acciones de preservación, monitoreo y gestión del ecosistema acuático. En total se identificaron 722 organismos asociados a macrofitas, 439 en periodo de lluvias y 283 en periodo seco, pertenecientes a 2 phylum, 5 clases, 11 órdenes y 20 familias; para los organismos en sedimentos se identificaron 148 organismos, 74 en periodo de lluvias y 74 en periodo de seco, pertenecientes a 3 phylum, 3 clases, 4 órdenes y 8 familias. El valor promedio del índice BMWP/Col para los macroinvertebrados asociados a macrofitas en periodo de lluvias define la calidad del agua de todas las estaciones como aguas ligeramente contaminadas y para el periodo seco como aguas muy contaminadas.
