“…This work represents an early effort to review, systematize, analyze, and gather the results of the various studies on aquatic macroinvertebrates in Peru, particularly in arid and semi-arid ecosystems. Likewise, it contributes valuable information to the knowledge of aquatic biodiversity and its distribution in these types of ecosystems for Latin America, in addition to the studies recently conducted in Argentina (Hankel et al, 2018;Domínguez et al, 2020), Venezuela (Rodríguez, 2020), Colombia (González and Moreno, 2017;Roldán, 2020), Mexico (López-López et al, 2019), Ecuador (Valdiviezo-Rivera et al, 2018, Brazil (Barbosa et al, 2012), Chile (Valdovinos, 2008), and Bolivia (Rocabado, 2003).…”

“…This boost in research productivity over the past 10 years probably reflects the effort made by some of the universities to finance research and training of human resources, not to mention the increased access to the information in some universities by acquiring the Web of Science database service, which is available to the university community. Also important is the development of Limnology, mainly in Colombia, which paved the way for other Latin American countries (Roldán, 2020). These 53 research studies have contributed valuable information about macroinvertebrate communities of arid and semi-arid ecosystems of Peru, as research projects to advance the knowledge of these aquatic ecosystems have become a priority (Hankel et al, 2018), facilitating the identification and classification of freshwater species, as well as a deeper insight on their life histories (Contador et al, 2012).…”

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.

“…These indexes rate the presence of families, who are assigned a score according to their tolerance to changes in their environment (BMWP/Col and ABI) (Ríos-Touma et al, 2014;Roldán-Pérez, 2016) or estimate the relative abundance of the orders Ephemeroptera, Plecoptera, and Trichoptera (Masese and Raburu, 2017). In the river studied, index values decreased at stations with greater urban impact since they showed tolerant families such as Psychodidae, Tubificidae, Syrphidae (Custodio and Chanamé, 2016;Roldán, 2020;Magallón et al, 2021). However, only BMWP/Col and ABI showed quality categories that differentiate one station from another, which is not the case with EPT due to the infrequent presence of organisms in such orders.…”

In the Anthropocene, man has imposed his activities above the natural processes of ecosystems. Rivers have undergone major changes associated with urban centers, so monitoring them is important to determine their status and suitability to provide environmental services. Studies applying the community ecology approach, such as energy flow in aquatic macroinvertebrate assemblages, may be appropriate to determine their status and functioning. This study characterized an Andean river that runs across the city of Ayacucho (Peru). Water physicochemical parameters and biotic quality indices were used and compared with the abundance of trophic guild components and functional feeding groups to demonstrate that the latter are at least equally suitable to estimate water quality. The river section studied ranged from 2640 to 2900 m a.s.l. and was monitored in the wet and dry seasons. Six monitoring stations were established according to the extent of the influence of the urban center. Water physicochemical variables and macroinvertebrate abundances were determined. A Surber net was used for multihabitat sampling; macroinvertebrates were identified to genus level (in most cases) and counted to estimate relative abundances. Trophic guilds (detritivore, predator, herbivore) were formed using the genus data from identification according to the information available in Argentina, Colombia, Ecuador, Bolivia, and Peru. Functional feeding groups were set based on the classification of families. The sensitivity of trophic metrics was assessed by relating them to environmental variables and the Andean Biotic Index (ABI), the Biological Monitoring Working Party adapted for Colombia (BMWP/Col.), and the Ephemeroptera, Plecoptera, Trichoptera (EPT) indices. Environmental variables and biotic indices increased significantly in the most impacted stations, where the abundance of most taxa decreased. The components of trophic guilds and functional groups varied, and those feeding on fine particles increased in sites with a higher urban impact. The metrics based on trophic characteristics were highly correlated with the BMWP/Col and ABI indices. Therefore, these indices can be used to estimate river water quality and provide information on its functioning.

“…Una de las comunidades bióticas más representativas en estos ecosistemas son los estadios juveniles (como huevo o larva) de macroinvertebrados acuáticos (Roldán-Pérez, 2016;Roldán, 2020;Williams, 2006), principalmente de insectos, gasterópos y crustáceos braquiópodos (Alonso, 1996;Ladrera, 2012;Tamaris-Turizo et al, 2020). Estos organismos son un componente fundamental en la dinámica trófica y flujo de la materia y la energía (Domínguez & Fernández, 2009), debido a que son fuente directa e indirecta de alimento para otras comunidades dentro y fuera del ecosistema.…”

Introducción: Las charcas temporales son ecosistemas acuáticos variables en su estructura física y biótica, efímeros en el paisaje e importantes en el flujo de materia y energía. Los macroinvertebrados acuáticos constituyen el grupo más abundante y diverso en estos ecosistemas, por ello, resulta de gran importancia comprender su composición temporal y espacial. Objetivo: Evaluar la diversidad alfa y beta de las comunidades de macroinvertebrados acuáticos de seis charcas temporales durante dos épocas climáticas en el norte de Colombia. Métodos: Se muestreó en la zona litoral y limnética empleando la red tipo D y draga van veen. Se utilizaron índices ecológicos de diversidad alfa y beta mediante el análisis de conglomerados para conocer los grupos conformados, finalmente, se realizó un análisis permutacional entre épocas climáticas y charcas. Resultados: se identificaron 3 358 individuos, representados por 13 órdenes, 39 familias y 68 géneros. La mayor abundancia y diversidad (N = 485, 0D = 32) durante la época de lluvia se presentó en Los Campanos, mientras que la charca Villa Leidy tuvo el mayor número de taxones comunes (18) y dominantes (14). En la época de sequía, la charca Los Trillizos presentó la mayor abundancia (533) y diversidad (43); mientras que Villa Leidy y El Miquito el mayor número de taxones dominantes (16). El análisis de disimilitud evidenció que las charcas tienen una composición particular, ya que no se evidenció agrupamiento a escala espacial ni temporal; además, se observó alto recambio de taxones. Finalmente, el análisis de correspondencia canónica exhibió un agrupamiento debido a la temporalidad. Conclusiones: la composición de las comunidades de macroinvertebrados acuáticos de las charcas temporales son muy diversas, presentando alto recambio tanto espacial como temporal, reflejando altos valores de remplazamiento de taxones entre ápocas climáticas. El análisis de los microhábitats mostró que la zona litoral mantuvo una composición similar durante el estudio.
