“…The highest percentages of total variance explained by filters acting on the Chironomidae assemblages were observed in the least disturbed sites because those populations are exposed to a series of, fluctuating but predictable and more stable conditions (Scheffer & Carpenter, 2003) as compared to severely disturbed sites. Severely disturbed sites, on the other hand, are often subjected to a spectrum of fluctuating disturbances (Feio et al, 2014;Gomes et al, 2018) that cause abrupt environmental changes and complex nonlinear population responses that make their identification and interpretation more difficult (Berryman & Millstein, 1989;Andersen et al, 2009).…”

“…1, supplementary material-Table S1 (available at http://www.limnetica.net/en/limnetica)). Those sites were known from previous studies to demonstrate different levels of anthropic disturbances (Gomes et al, 2018). All of the sampling sites were located in the littoral region of the reservoirs (at an average depth of 60 centimeters), because those areas are strongly influenced by the riparian zone and normally harbor the greatest species richness and abundances of benthic macroinvertebrates (Magbanua et al, 2015).…”

“…The habitats were characterized according to the granulometric compositions of their sediments. We collected sediment samples at each site using an Eckman-Birge dredge (area 0.225 m 2 ) and determined their granulometric compositions following the methodology described by Suguio (1973) and modified by Callisto & Esteves (1996), as recommended in other studies (e.g., Molozzi et al (2013), Azevêdo et al (2017), and Gomes et al (2018)). We dried the sediment samples at 60 ºC for 72 hours and mechanically separated the fractions by mechanical agitation through a series of sieves.…”

Effect of environmental filters on Chironomidae (Insecta: Diptera) assemblages of neotropical watershedsEnvironmental filters act at different spatial scales, selecting species with characteristics that allow them to successfully establish and survive under local environmental conditions. We sought to evaluate how environmental filters (physical/chemical, habitat composition, and landscape) and different levels of anthropogenic disturbances affect the abundance of Chironomidae in neotropical semiarid watersheds. Chironomidae larvae were sampled in six reservoirs (112 sites) in the Piranhas-Assu and Paraíba watersheds (NE Brazil) during the dry season. The distribution of Chironomidae larvae was best explained in Least Disturbed sites, with 82.1 % of the total explained variance in the Piranhas-Assu watershed and 64.2 % in the Paraíba watershed. The interactions of filters (physical/chemical, habitat composition, and landscape) best explained the abundance distributions of Chironomidae larvae in the watersheds and sites subjected to different levels of anthropogenic disturbances. The physical/chemical conditions of the water as well as habitat composition depend on landscape characteristics, because anthropogenic activities in watersheds increase nutrient concentrations in the water, promoting the increase of the trophic state of the environment as well as habitat homogenization. This study showed that, independent of the anthropogenic disturbance level, interactions of environmental factors act as strong environmental filters on the distributions of local communities, such as Chironomidae assemblages.

“…La contaminación de los sistemas acuáticos y su efecto sobre la biodiversidad, es un tema crítico donde se requiere un análisis constante (Alizadeh et al, 2018;Shamshirband et al, 2019). Entre los métodos aceptados para la evaluación de la calidad de agua está el biomonitoreo (Romero et al, 2017), el cual resulta sencillo, de fácil acceso y sostenible (Gomes et al, 2018).…”

El propósito del estudio fue describir la bioevaluación analítica del modelo predictivo de la ciencia en ecotoxicología acuática. Desde el sitio web de Sciencedirect se analizaron 18 revisiones científicas, 72 artículos científicos, seis enciclopedias y 32 capítulos de libros que correspondieron a 11 revistas científicas. Se propuso dos descriptores: 1ro) de las condiciones de campo el cual, refirió al desarrollo natural de organismos y, 2do) de las condiciones de laboratorio donde se consideró tres tipos de ensayos: A) potencial de toxicidad, B) de crecimiento y, C) de transformación. Aunque, la ventaja de las condiciones de campo es la desventaja en condiciones de laboratorio resulta indispensable que las bioevaluaciones se combinen para que los servicios ecosistémicos sean sostenibles en la sociedad. Desde diversas bioevaluaciones de condiciones de campo y de laboratorio se puede construir, datos que tengan significación estadística y su argumentación constituyan nuevas premisas. Se concluye que, la bioevaluación analítica de cualquier modelo predictivo de la ciencia en ecotoxicología acuática puede realizarse desde condiciones de campo o de laboratorio y donde la teoría falseable que se origine, esté orientada a prácticas reconocibles desde los servicios ecosistémicos.

“…La principal limitación en el estudio fue la determinación de parámetros físico-químicos y microbiológicos, y se recomienda para futuras investigaciones determinar índices de calidad ambiental del agua (Stefanidis et al, 2016;Luo et al, 2018), así como bioevaluaciones (Gómez et al, 2017;Gomes et al, 2018), y con ello valorar la reutilización social de las aguas en la laguna de la Huacachina.…”

Heritage areas with tourist attractions that offer ecosystem services must be systematically evaluated for their preservation. The objective of the manuscript addressed to the Editor describes the latent environmental damage in the Huacachina lagoon, Ica-Peru. The contact and physical pressure of the dune on the containment barriers was observed, which could prevent the recreation of passers-by in the future. Likewise, an excessive density of the Scirpus californicus species, which is an indicator of the poor quality of the water and which is corroborated by the high turbidity.
