“…Of those Sphaeriidae, Planorbidae, Lymnaeidae, Physidae, Hydrobiidae and Ancylidae are the only families that have been reported in Andean areas above 2 000masl (Posada et al, 2000;Carrera & Gunkel, 2003;Jacobsen, 2004) and were the only ones included in our index. Benthic Crustacea reported in Andean areas includes: Ostracoda and Hyalellidae (Amphipoda) (Vásconez, 2000;Ríos-Touma, 2004;Ríos-Touma & Prat, 2004;Acosta & Prat, 2011). Hyalella is the only freshwater Hyalellidae genera present in South America (Peralta, 2001), but we kept this taxon as a family for the index.…”

“…Moreover, these values are consistent with the presence of these taxa in a wide range of water conditions (Machado et al, 1997; Viña-Vizcaíno & Ramírez-Gonzáles, 1997;Jacobsen & Encalada, 1998;Vásconez, 2000;Ríos-Touma, 2004;Ríos-Touma & Prat, 2004). Hyalellidae is found in a wide variety of habitats, shows diverse feeding strategies (Peralta, 2001;Acosta & Prat, 2011), and is resistant to certain types of organic pollution (Jacobsen & Encalada, 1998). Therefore, we used the score for Gammaridae (6) from the index developed by Armitage et al (1983), which is consistent with the frequent presence of this family in reference to mildly impaired streams.…”

Score-based biotic indices are widely used to evaluate the water quality of streams and rivers. Few adaptations of these indices have been done for South America because there is a lack of knowledge on macroinvertebrate taxonomy, distribution and tolerance to pollution in the region. Several areas in the Andes are densely populated and there is need for methods to assess the impact of increasing human pressures on aquatic ecosystems. Considering the unique ecological and geographical features of the Andes, macroinvertebrate indices used in other regions must be adapted with caution. Here we present a review of the literature on macroinvertebrate distribution and tolerance to pollution in Andean areas above 2 000masl. Using these data, we propose an Andean Biotic Index (ABI), which is based on the BMWP index. In general, ABI includes fewer macroinvertebrate families than in other regions of the world where the BMWP index has been applied because altitude restricts the distribution of several families. Our review shows that in the high Andes, the tolerance of several macroinvertebrate families to pollution differs from those reported in other areas. We tested the ABI index in two basins in Ecuador and Peru, and compared it to other BMWP adaptations using the reference condition approach. The ABI index is extremely useful for detecting the general impairment of rivers but class quality boundaries should be defined independently for each basin because reference conditions may be different. The ABI is widely used in Ecuador and Peru, with high correlations with land-use pressures in several studies. The ABI index is an integral part of the new multimetric index designed for high Andean streams (IMEERA). Rev. Biol. Trop. 62 (Suppl. 2): 249-273. Epub 2014 April 01.Key words: Andes, aquatic macroinvertebrates, altitudinal distribution, tolerance to pollution, BMWP adaptations, biomonitoring, water quality.Aquatic macroinvertebrates are ubiquitous, and their sensitivity to environmental changes makes them good indicators of water condition. Diversity and biotic indices for benthic macroinvertebrate samples are often applied in an attempt to measure river pollution (Giller & Malmqvis, 1998). Score-based biotic indices are one of the most common biomonitoring methods used by water managers to synthesize large amounts of data from environmental monitoring. In these indices, a score is given to taxa (usually family or genera level) according to tolerance to organic pollution, giving highest or lowest scores (depending on the index) to sensitive taxa. These indices synthesize ecological information and the results are more accessible to non-biologists who require data for management purposes (Armitage, Moss, Wright & Furse;. Indices of this kind were developed mainly in Europe (Woodiwiss, 1964;Armitage et al., 1983), South Africa (Chutter, 1972), North America (Hilsenhoff, 1982;1987) and Australia (Chessman, 1995). One of the most commonly used index is the BMWP (and its derivations), which was developed in 1978 by...

“…Many studies have reported that Chironomidae and Oligochaeta are important colonizers of artificial substrates (Carvalho & Uieda 2004, Souza et al 2008, Barker et al 2014. However, on Amphipoda most information refers its taxonomy, biology, ecology, and their association with aquatic macrophytes and macroalgae (Jacobucci & Leite 2002, Saigo et al 2009, Acosta & Prat 2011, Bastos-Pereira & Bueno 2013. A study on temporal and spatial patterns of macroinvertebrates associated with different floating macrophytes revealed that when the area covered by R. natans is large, the macroinvertebrate community is dominated by Hyalella curvispina amphipodes Oecol.…”

“…Aust., 21(4): 407-421, 2017 (Fontanarrosa et al 2013). Amphipoda individuals are commonly found in association with macrophytes and macro-algae (Jacobucci & Leite 2002) and present an herbivorous or herbivorous-detritivorous feeding habit (Jacobucci & Leite 2006, Saigo et al 2009, Acosta & Prat 2011, Barker et al 2014. This peculiarity of these organisms can explain the dominance of crustaceans in R. natans and S. intermedia stands, attaining approximately 50% of the relative abundance.…”

Understanding how the process of colonization by taxa in different types of habitat takes place is necessary to preserve their diversity. The aim of this study was to analyze the process of colonization by macroinvertebrates on an artificial substrate with morphology similar to that of the roots of aquatic macrophytes Ricciocarpus natans and Spirodela intermedia, which were present in the environment investigated. The hypothesis is that the values of total density on the artificial substrate will show a tendency similar to that of a macrophyte stand, but with a different taxonomic composition. The differences in taxa density and composition associated with the artificial substrate and macrophytes were significant. The total density and richness on the artificial substrate did not follow an upward curve with a significant increase in the number of individuals during the experiment, probably due to the heavy rainfall observed. The variation in the density values in both substrates shows that the macroinvertebrate community was maintained through an "emigration" and "immigration" dynamic. Our hypothesis was confirmed only in relation to the taxonomic composition. The colonization of the artificial substrate by macroinvertebrates might have been more efficient had the environment not received frequent rains, which affected the physical stability of the macroinvertebrate community. Therefore, intrinsic sampling site characteristics may have attenuated the effect of the flood pulse on the macroinvertebrate communities, since only oscillations in the density values of the taxa were observed, rather than their exclusion.

“…The reduced detrital processing is ecologically meaningful because Hyalella and other members of the shredder guild consume high amounts of detrital material in the field (Acosta and Prat 2011). This assertion is supported by studies with another leaf shredding amphipod (i.e., Gammarus), which is a key organism in the leaf decomposition process in Central European rivers (e.g., Dangles et al 2004).…”

Purpose Mercury (Hg) released into the environment often accumulates to high concentrations in sediments, creating a potential risk to aquatic wildlife. The in situ application of sorbents such as activated carbon is one promising option for reducing the bioavailability of sediment-bound Hg. Materials and methods The present study evaluates the influence of contact time of two sorbents (Sedimite ® and Cowboy ® biochar) applied to sediment taken downstream and upstream of a historic Hg discharge into the South River (Virginia, USA) on bioaccumulation in and detrital processing by Hyalella azteca. Results and discussion Hg bioaccumulation decreased when sediments were mixed with both sorbents, but their respective efficiency depended on their initial particle size and contact time. Hyalella showed a slight increase in detrital processing and substantial increase in Hg bioaccumulation when exposed to contaminated relative to uncontaminated sediment.Sedimite ® adversely affected detrital processing but reduced Hg bioaccumulation. In contrast, Cowboy ® biochar did not impact detrital processing but appeared to decrease bioaccumulation less effectively than Sedimite ® . This difference in sorbent efficacy lessened with duration. It remains unclear whether the Sedimite ® -induced reduction in detrital processing is substantially worse than that associated with natural fines settling on detritus in depositional reaches of rivers. Conclusions The differences in efficacy of the two materials in reducing bioavailability suggest the need for further studies addressing both the mechanisms causing the reduction in Hg bioavailability as well as associated ecological risks prior to field application of these materials at the larger scale.
