Plastics, especially microplastics (<5 mm in length), are anthropogenic polymer particles that have been detected almost all environments. Microplastics extremely persistent pollutants and act as long-lasting reactive surfaces for additives, organic matter, toxic substances. Biofilms microbial assemblages a sink particulate including microplastics. They ubiquitous freshwater ecosystems provide key services promote biodiversity help sustain ecosystem function. Here, we conceptual framework to...
We assessed the effects of nutrient enrichment on three stream ecosystems running through distinct biomes (Mediterranean, Pampean and Andean). increased concentrations N P in water 1.6–4-fold following a before–after control–impact paired series (BACIPS) design each stream, evaluated changes biomass bacteria, primary producers, invertebrates fish enriched (E) versus control (C) reaches after addition predictive-BACIPS approach. The treatment produced variable responses (2–77% explained...
ABSTRACT Transformations in agricultural practices, particularly regarding chemical inputs such as pesticides, affect physical and characteristics biotic communities of streams. Currently, many conventional production systems are transitioning to economically environmentally more sustainable production, which aims reduce the use synthetic inputs. However, it remains unclear whether agroecological practices positively impact environment. Here, we compared toxicity sediments from streams areas...
Bioengineering techniques are currently used in a wide variety of wastewater treatment systems. Aquatic plants (i.e., helophytes) these reduce excess nitrogen (N) from water column via assimilation. Moreover, leachates plant leaf-litter can serve as an additional source labile dissolved organic matter (DOM), which promote aerobic respiration and N removal denitrification. We tested the influence Iris pseudacorus Phragmites australis on structure activity freshwater biofilms grown flumes fed...
Abstract Agricultural activities can affect the delivery of nutrients to streams, riparian canopy cover, and capacity aquatic systems process sediments. There are few measures nutrient uptake metabolism from tropical or subtropical streams in general, even fewer regions South America. We examined ammonium (NH 4 + ) soluble reactive phosphorus (SRP) retention Brazil Argentina. selected 12 with relatively little extensive agricultural activity conducted whole‐stream additions measurements...

Abstract The calculation of autoecological data, such as optima and tolerance ranges to environmental variables, can be useful establish the distribution abundance species. These calculations, although mathematically not complex, prone error when using a large database. We show how calculate optimum value multiple species factors in single run, by weighted average specific R package (‘optimos.prime’). Using sample data from phytoplankton database, we exemplify use its functions. A...
Citizen science, or participatory is the process by which general public actively contributes with scientifc projects. science projects have proliferated in few last decades thanks to Internet and are proving be a great complement more "traditional" environmental monitoring efforts. AppEAR (an app evaluate aquatic habitats) states as its main objective map status of habitat continental waterbodies, primary focus on shores coasts, within citizen framework. It consists free mobile that allows...
Abstract The aim of this study was to describe the colonization biofilm during its early stages under different concentrations nutrients and organic matter, specifically in urban streams influenced by agriculture urbanization. We hypothesized that a stream with higher initial biomass growth would be faster, changes structure community greater. Sterile glass substrates were placed 2 differed nutrient matter concentrations; samples collected their first week measure total biomass, bacterial...
Evaluating the coastal environment is a necessary task to assess ecological status of water bodies, which allows determine merits management programs, anthropogenic impacts, or detect early signs environmental impacts. To this purpose, objective research was develop methodology habitat quality in Franja Costera Sur Río de la Plata. The information obtained from 21 sampling sites, visited 2005 2008, summarized and simplified an index, named Habitat Index for Plata (IHRPlata). obtain index...
Chagas disease is one of the most important public health problems in America, involving triatomines (Hemiptera: Reduviidae: Triatominae) vectorial transmission Trypanosoma cruzi (Protista: Kinetoplastea: Trypanosomatidae). In Argentina, 15 species are distributed, which seven common domicile and peridomicile, while rest mainly associated with wild environments. Due to lack updated data geographic distribution, GeoVin Project arises provide not only a triatomine digital tool notification,...
The colonisation patterns of diatom assemblages were studied on artificial substrates in lowland streams with different urban pollution levels. Density, diversity, rates, ecological guilds and cell size classes the assemblage at each two sites followed for 1 week. In addition, growing glass, natural epipelic biofilm water compared site. At both sites, glass had already started after 30-min exposure. less polluted site, total density was higher, along proportion low-profile motile species,...
