Improving collection technologies is crucial to develop effective and economically feasible solutions for catching plastic from riverine environments. However, floating booms are being constructed and deployed in river around the world without rigorously testing its effectiveness. In this study, we tested the effectiveness of a boom under realistic...
This study presents a comparison between fishers’ knowledge and fiscal records about the structure of inland fisheries in the Paraná River (Argentina). First of all, we characterized the fishing population according to the main demographic and economic indicators, identifying two different fishing areas: the northern and southern sections in the lo...
The present study is a full review of the non-native freshwater fish species introduced into Argentina and their relationship to the main environmental features and introduction vectors of each freshwater ecoregion. The total number of non-native freshwater fish species was compiled through a literature survey; information on spatial–temporal patte...
The Parana River is ranked among the top-ten major rivers of the world. During the last century, the expansion of agriculture and the construction of large dams strongly modified the upper basin but the middle and lower sections are still among the few free-flowing river reaches of this magnitude in the world. However, the great anthropic pressure...
"The journey of plastic garbage in the Middle Paraná River". Rivers
are known to play a critical role in transporting land‐based plastic debris to the world's oceans, but riverine ecosystems are also directly impacted by plastic pollution. Although notable scientific efforts have been made to quantify and classify these impacts, they are still insu...
This study deals with the effects of climate fluctuations and anthropogenic impacts on fisheries of Paraná River over the last 100 years. It is the first attempt to appraise the influence of hydro-climatic and anthropogenic variables on the population changes of the most important inland fisheries of Argentina. Datasets covering more than eight dec...
Plastic pollution has become a globally pressing environmental issue. In birds, plastic may cause harm by entangling or ingestion when used for nesting. The use of anthropogenic nesting material has so far been mostly studied in birds of terrestrial or marine habitats, but there are yet very few reports for inland water–associated birds. The aim of...
Channel networks of floodplain rivers are the main routes for water, sediment, organic
matter, and aquatic organisms between main channels and lakes, playing a substantial role in
floodplain dynamics. Despite their importance most investigations in large floodplain rivers focus on
main channels and lentic water bodies. This research deals with fish...
This paper deals with the hydrological variability effects on the primary commercial fish species inhabiting the main channel and the floodplain of the large Paraná River in its middle reaches in Argentina. Analysing more than eight decades (1935–2016) of information on the most frequent and abundant commercial species in conjunction with hydrologi...
This study examines the effects of the flow and flood pulses on spatial dispersion of fish assemblages in the floodplain of the Paraná River in Argentina. We tested the hypothesis that high water levels and greater lateral connectivity promote fish dispersal and spatial homogenization of assemblage structure. We sampled four sites during different...
The overwhelming majority of research conducted to date on plastic pollution (all size fractions) has focused on marine ecosystems. In comparison, only a few studies provide evidence for the presence of plastic debris in freshwater environments. However, owing to the numerous differences between freshwater studies (including studied species and hab...
Fluctuations of temperature and water levels are the two main drivers of aquatic life in river floodplain ecosystems. The large Middle Paraná River floodplain exhibits marked seasons and important interannual hydrological changes. Using a three-factor-based approach (fish reproductive traits, hydroclimatic conditions, and floodplain recruitment pat...
El sábalo es una especie de gran importancia ecológica y económica que se distribuye
en ríos de la Cuenca del Plata, la segunda en importancia en Sudamérica. Es un
eslabón crucial en los ecosistemas paranoplatenses ya que es sostén de su cadena
trófica. Presenta alta fecundidad, alta longevidad (hasta 25 años) y comportamiento
migratorio de alta mo...
With the objective of finding fluctuations on fish body condition in the Middle Paraná River floodplain in different hydrological scenarios, this attribute was analyzed in several trophic groups of a secondary floodplain channel and its associated lakes between 2010 and 2012. Standardized residuals generated by length-weight regressions were calcul...
Interdisciplinary research in the fields of ecohydrology and ecogeomorphology is becoming increasingly important as a way to understand how biological and physical processes interact with each other in river systems. The objectives of the current study were 1) to determine changes in invertebrate community due to hydrological stages, 2) to link loc...
We analysed the effects of decadal and annual hydrologic fluctuations on freshwater fisheries catches in the Middle Paraná River for a period of six decades from the 1930s to the 1980s. The climatic fluctuations in this period strongly affected the hydrology of the Middle Paraná River and the characteristics of its flow regime. The magnitude of flo...
Fish assemblages recorded from August 2010 to July 2013 in two lotic and lentic environments of the Middle Paranć River floodplain were studied in the light of flood and flow pulse variations. Three flood pulses occurred during the period of study, each with a different magnitude, duration and timing. Instead four flow pulses were recorded during t...
Temporal variations of fish abundance and species richness in two sites of a secondary channel of the Middle Parana ́ Floodplain (Argentina) have been analyzed from 2010 to 2012. Relationships of these ecological attributes with alternations of floods and dry periods were appraised. Permutational analyses of variance were applied to determine signi...

Despite research efforts investigating plastics in oceans, little studies have focused on freshwater systems. Estimations of plastic debris occurrence in freshwater environments are urgent. Freshwater invertebrates, fish and birds can ingest plastics particles, causing serious injuries, disease and bioaccumulation. The aim of this proposal is to determine occurrence, abundance and spatial distribution of micro-, meso- and macroplastic debris in sediments of the Paraná River (Argentina). Results will be compared with other rivers worldwide in order to understand the plastic pollution situation in this river. Mitigation measurements will be proposed and discussed with local NGOs and government agencies.
