“…Assessment of biomonitoring protocols has been conducted in Brazil, Mexico, Argentina, Bolivia, and Ecuador, with most studies applying slightly modified versions of biotic indices generated in Europe, such as the BMWP and/or Average Score Per Taxon (ASPT or BMWP/taxon richness) index to detect impairment (e.g., Jacobsen 1998;Tarras-Wahlberg et al 2001). Other studies have adapted and tested biotic indices (e.g., Capítulo et al 2001;Mugnai et al 2008;Junqueira et al 2010), multimetric indices (Weigel et al 2002;Baptista et al 2007;Ferreira et al 2011;Oliveira et al 2011b), multivariate models (Moreno et al 2009), and predictive multimetric models (Moya et al 2011) for basin or regional use.…”

Water quality agencies and scientists are increasingly adopting standardized sampling methodologies because of the challenges associated with interpreting data derived from dissimilar protocols. Here, we compare 13 protocols for monitoring streams from different regions and countries around the globe. Despite the spatially diverse range of countries assessed, many aspects of bioassessment structure and protocols were similar, thereby providing evidence of key characteristics that might be incorporated in a global sampling methodology. Similarities were found regarding sampler type, mesh size, sampling period, subsampling methods, and taxonomic resolution. Consistent field and laboratory methods are essential for merging data sets collected by multiple institutions to enable large-scale comparisons. We discuss the similarities and differences among protocols and present current trends and future recommendations for monitoring programs, especially for regions where large-scale protocols do not yet exist. We summarize the current state in one of these regions, Latin America, and comment on the possible development path for these techniques in this region. We conclude that several aspects of stream biomonitoring need additional performance evaluation (accuracy, precision, discriminatory power, relative costs), particularly when comparing targeted habitat (only the commonest habitat type) versus site-wide sampling (multiple habitat types), appropriate levels of sampling and processing effort, and standardized indicators to resolve dissimilarities among biomonitoring methods. Global issues such as climate change are creating an environment where there is an increasing need to have universally consistent data collection, processing and storage to enable large-scale trend analysis. Biomonitoring programs following standardized methods could aid international data sharing and interpretation.

“…Saprobic indices, developed using protozoans, phytoplankton, and rotifers have been extensively used to evaluate the water quality in lentic and lotic systems (Junqueira, Friedrich, & Pereira de Araujo, ). Rotifers are particularly useful in this regard because they are easy to recognize even when preserved and are sensitive to many pollutants (Sarma & Nandini, ; Snell & Joaquim‐Justo, ).…”

Planktonic organisms are good indicators of water quality but are rarely used in Mexican riverine studies in spite of the high level of contamination in these lotic waters. In this study, we focused on the plankton of the river Amacuzac in Mexico and a large saline waterbody, Lake Tequisquitengo, which is located in the Amacuzac river basin. We collected samples at three sites in the River Amacuzac and one at Lake Tequisquitengo from May 2015 to March–April of 2016. We analysed the physicochemical variables, coliform bacteria, and biological oxygen demand levels. We also quantified phytoplankton and zooplankton. Our results indicate that the study sites are mesotrophic with high densities of diatoms and cyanobacteria. Among the zooplankton, the dominant organisms were rotifers. The constancy of planktonic taxa was high in the lake but low in the river. The Descy index ranged from 2.9 to 4.5 in the river and from 4.0 to 5.0 in the lake. The saprobic index shows that the system is β‐mesosaprobic. The species diversity was higher in the river than in the lake. Our study shows that plankton can efficiently be used to evaluate the water quality in rivers and lakes.

“…Most of these approaches indicate the general pollution level of the water, especially saprobity. Each species of aquatic organism is characteristic of different intensities of organic matter load and levels of self-purification in water courses (Junqueira et al 2010). The saprobity system is based on observations of rivers that have received a heavy load of sewage and that show distinct zones of decreasing pollution.…”

This study surveyed physical, chemical, and biological parameters in a dammed pool in comparison to those of the adjacent main stream. Because the dammed pool in this study was a unique zone formed by a slit check dam, the properties of the pool and the main stream could be considered representative of the conditions with and without a slit check dam, respectively. Data were collected in the dammed pool and in the reach of the main stream above the slit check dam in the Wasada Stream, Miyagi Prefecture, Japan. The dammed pool exhibited a lower velocity and finer substrate than those of the main stream. In addition, the water temperature in the dammed pool was slightly higher than in the main stream. Dissolved Oxygen and Chemical Oxygen Demand in the pool were lower than the allowable standards for water pollution. The pool exhibited worse biological indices of water quality than the main stream. Out of a total of 18 taxa found in the stream, only 5 taxa were found in the dammed pool. Most individuals in the dammed pool belonged to the genus Chironomus, which tends to colonize heavily polluted sites. According to these various indicators, the water quality of the dammed pool was lower than that of the main stream. The longest durations of the presence of the dammed pool mainly occurred during snowmelt and during the rainy season. The average duration of the presence of the dammed pool was calculated as 14 days. The dammed pool exhibited a short-duration cycle of formation and extinction according to seasonal variations in water discharge. This cycle reduces the negative effects of the pool on water quality. Therefore, the dammed pool has a minimal negative effect on restoration of the entire reach of the Wasada Stream.
