“…To note, the cosmopolitan family Chironomidae (Andersen et al, 2000;Saether and Ekrem, 2003) showed the highest frequency in the study area, consistent with previous studies of arid and semi-arid environments in South America (Scheibler, 2008;Colla et al, 2013;Zelarayán and Salas, 2014;Ferru and Fierro, 2015;Domínguez et al, 2020).…”

“…The information sources reviewed resulted in a total of seven phyla, 10 classes, 39 orders, and 118 families of aquatic macroinvertebrates recorded in arid and semi-arid ecosystems of Peru, with the most representative groups belonging to the class Insecta; these findings are consistent with previous investigations conducted in Peru (Ortega et al, 2010;Lujan et al, 2013;Arana and Cabrera, 2017;Carrasco et al, 2020;Sweeney et al, 2020). Geographically, the western hydrographic slope recorded the highest richness of the different taxonomic categories, probably because most research studies (theses and scientific articles) were conducted in this area (Figure 3).…”

Peru is one of the megadiverse countries worldwide, displaying a great diversity of ecosystems due to its tropical location, marine currents, and complex relief, which jointly define environments differentiated by altitude and climatic conditions. The arid and semi-arid ecosystems comprising xeric and Andean shrublands, coastal deserts, and coastal hills, illustrate this diversity of ecosystems; these stretch over 177 358 km2, representing 13.8% of the Peruvian territory. Several studies on aquatic macroinvertebrates are being conducted in these ecosystems; although not so numerous yet, have shown a rise in recent years. The objective of this work was to determine the composition and distribution of aquatic macroinvertebrates in the arid and semi-arid ecosystems of Peru. To this end, we conducted a literature survey; the articles and theses found were reviewed and analyzed. The following keywords were used: macroinvertebrates, macrozoobenthos, bioindicators, diversity of aquatic organisms, and water quality; we used the Google Academic search engine, Scopus, Web of Science, ResearchGate and the thesis repositories of Peruvian universities, additionally a thesis from the University of Barcelona. Of a total of 53 sources of information, 38 are theses and 15 are scientific articles conducted from 1992 to 2020, referring to studies conducted at elevations ranging from 0 to 3,831 m asl. Most studies were conducted at the Lima and La Libertad departments, resulting in 20 and 10 publications, respectively. The topics addressed most frequently were bioindication, biodiversity, taxonomy, and distribution. Most theses were carried in the Universidad Nacional de Trujillo and the Universidad Nacional Mayor de San Marcos, with 12 and 10 theses, respectively. The period 2011–2020 records the largest number of publications (40). According to the type of aquatic ecosystem, rivers (38) were the systems most intensively studied, followed by coastal wetlands (14) and lagoons (2); to note, one thesis studied two types of ecosystems. Specimens were collected mainly with the Surber and D nets; as a result, seven phyla, 10 classes, 39 orders, and 118 families were reported. The highest richness of families corresponds to rivers (110), followed by coastal wetlands (57), and lagoons (12). The western hydrographic slope recorded the highest richness at phylum, class, order, and family levels, likely because most investigations were conducted in this slope. On the other hand, the phyla Cnidaria, Nematoda, and Nematomorpha were not recorded in the eastern slope, which showed fewer orders (19) relative to the western slope (39). A similar trend is observed at the family level: of the 118 families recorded, 59 were reported for the eastern slope. The most common families at both sides were Chironomidae, Baetidae, Simuliidae, Elmidae, Hydrophilidae, Libellulidae, Physidae, Dytiscidae, Ceratopogonidae, Coenagrionidae, Hydroptilidae, Hydropsychidae, and Tipulidae. Separately, the most common families in all types of aquatic ecosystems were Chironomidae, Baetidae, and Dytiscidae. It is recommended to further promote studies on macroinvertebrates living in the eastern slope, addressing taxonomic, and ecological topics, as well as broadening the approach to an integral ecosystem view. Finally, the biotic indices should be calibrated and validated for the main hydrographic basins. This work is an initial effort to review, systematize, analyze, and gather the results of studies on aquatic macroinvertebrates in Peru, particularly in arid and semi-arid ecosystems.

In this work, the distribution of Amanahyphes genus and A. saguassu Salles & Molineri species is expanded through the first records from Colombia and Perú. The departments where these specimens were found belong to the Amazon region of both countries, they are: Amazonas, Guaviare and Vaupés (Colombia); Madre de Dios (Perú). The species identified in this work was previously recorded only in Brazil and Venezuela.

“…Some uni‐ and multi‐metric biotic indexes were specifically developed to be applied on central Andean ecosystems, such as the Andean Biotic Index—ABI (Acosta et al, 2009; Rios‐Touma, Acosta, & Prat, 2014) and the IMEERA (from the Spanish “Índice Multimétrico del Estado Ecológico de los Ríos Altoandinos”) (Villamarín et al, 2013). Likewise, indexes such as BMWP/Col and IBF were adapted from others developed for European countries but extensively used in Peruvian publications and environmental studies (Custodio & Chávez, 2019; Flores & Huamantinco, 2017; Mora, Medina, Polo‐Corro, & Hora, 2020; Sweeney et al, 2020; Tapia et al, 2018; Trama et al, 2020). Although the biotic indexes are essential tools to detect natural or anthropogenic changes in aquatic environments due to their easy measurement and interpretation related to anthropic impacts, there is not an ideal biotic index (Bonada, Prat, Resh, & Statzner, 2006; Chará‐Serna, Chará, Giraldo, Zúñiga, & Allan, 2015; Karr & Chu, 1997; Resh & Rosenberg, 2010; Rios‐Touma et al, 2014; Villamarín et al, 2013).…”

As in many other countries, Peru has the Water Quality Standard (WQS) as the primary tool for managing and diagnosing water resources. An analysis of variable by variable was applied to define water quality as poor or good by setting concentration limits. A second group of tools commonly used are Biotic Indexes based on tolerance of benthic macroinvertebrates to pollution, that reflect the impacts caused by a group of variables, even though they cannot identify which variables determine the viability of the ecosystem. This research proposes to include the Stable States approach to evaluate the ecological integrity in central‐Andes rivers to explore an alternative approach with the capacity to represent a broader number of factors through multivariate analyses. A ten‐year database of biological, physical, and chemical variables measured in five Andean Rivers was evaluated. Our results suggest these rivers fluctuate into two seasonal stable states (wet and dry season), accounting for approximately 41% of the system variability. The wet season stable state was defined by high levels of suspended solids and turbidity, coliform, phosphorus, and some metals. During the dry season, the key variables were dissolved solids, barium, pH, and dissolved oxygen. Likewise, there seems to be a third alternative state influenced by human pressures driven by organic pollution variables that exceed the WQS. Regarding water quality, the concentrations of coliforms, phosphorus, and lead usually exceeded the limits in two stations, but not every year. Between bioindicator indexes, the ABI represented the ecological condition more accurately than EPT.
