Fishes, 2023 Dietary uptake is well known as the predominant pathway of heavy metal bioaccumulation in organisms. Our study used a typical tropical reservoir and fish as a modeling system to test the hypothesis that feeding habits and living habitats significantly ...

Phytoplankton functional responses induced by extreme hydrological events in a tropical reservoir. [PDF]
Hydrobiologia, 2023 Climate change is affecting the global hydrological cycle, causing drastic changes in precipitation patterns. Extreme climatic events are becoming more frequent and intense than in the past, leading to water-level fluctuations and affecting aquatic ...

Underwater drones reveal different fish community structures on the steep slopes of a tropical reservoir. [PDF]
Hydrobiologia, 2022 A new approach for visual fish survey in reservoirs using underwater drones (remotely operated vehicle- ROV) is presented. The ROV was applied to identify abiotic gradients and to compare fish assemblages on the steep slopes in a tropical reservoir.

'Floc and Sink' Technique Removes Cyanobacteria and Microcystins from Tropical Reservoir Water. [PDF]
Toxins (Basel), 2021 Combining coagulants with ballast (natural soil or modified clay) to remove cyanobacteria from the water column is a promising tool to mitigate nuisance blooms.

Predicting Antibiotic Resistance and Assessing the Risk Burden from Antibiotics: A Holistic Modeling Framework in a Tropical Reservoir. [PDF]
Environ Sci TechnolPredicting the hotspots of antimicrobial resistance (AMR) in aquatics is crucial for managing associated risks. We developed an integrated modeling framework toward predicting the spatiotemporal abundance of antibiotics, indicator bacteria, and their ...

Modelling the impact of sediment management on the trophic state of a tropical reservoir with high water storage variations [PDF]
Anais da Academia Brasileira de Ciências, 2020 Eutrophication of lakes has affected society in many regions, particularly in water scarce environments where: i) low runoff reduces the self-purification potential of water bodies; ii) water supply relies on surface reservoirs, which are susceptible to ...

Estimation of greenhouse gas emissions of a tropical reservoir in Colombia
Journal of Water and Climate Change, 2022 Tropical reservoirs are generally flooded in soils with a high content of organic matter. This, combined with high temperatures, favors the generation of carbon dioxide and methane by biological degradation, contributing to the impact on climate change ...

Analysis of different hypotheses for modeling air–water exchange and temperature evolution in a tropical reservoir [PDF]
Journal of Water and Climate ChangeThe present analysis shows that the most crucial parameter for a correct representation of the observed temperature behavior are the heat exchange coefficient and the wind.
