Detecting droughts as early as possible is important in avoiding negative impacts on economy, society, and environment. To improve drought monitoring, we studied drought propagation (i.e., the temporal manifestation of a...

There is considerable confusion in the literature regarding the systematic position and distribution of two pseudothelphusid crabs originally described as Potamocarcinus reflexifrons Ortmann, 1897 and Potamocarcinus refl...

The EU's Chemicals Strategy for Sustainability aims to incorporate environmental risk of combined exposure, stemming from unintentional chemical mixtures in the environment, into regulatory risk assessments. Within the E...

The capybara, Hydrochoerus hydrochaeris, is an herbivorous rodent widely distributed throughout most of South American wetlands that lives closely associated with aquatic environments. In this work, we studied the geneti...

Droughts negatively affect basins by reducing the river streamflow and increasing ion concentrations due to lower dilution. This study examines the impact of droughts in the Colorado River basin in Argentina. For this pu...

The Global Flood Awareness System (GloFAS) is a promising flood-modelling tool available for most river basins worldwide. However, it contains inherent biases, notably linked to its spatial resolution. This study propose...

Abstract River water quality forecasting on directed river networks requires jointly modeling temporal dynamics and directional spatial dependencies among monitoring sites. Existing spatio-temporal models often emphasize...

Macrobrachium surinamicum is an indigenous prawn distributed from the lower Amazon and Tocantins river basins to Venezuela in the Orinoco Delta region. It is common bycatch fauna of Macrobrachium amazonicum artisan fishi...

Many developing countries have experienced rapid industrial and urban expansion over the last two decades, raising concerns about ecological degradation. However, quantitative assessments linking urbanization and ecologi...

As pressures on water and energy systems increase, integrated governance of water-energy nexus has gained importance. In Brazil, where hydropower is the main source of electricity and droughts are frequent, managing this...

Neste estudo foram analisados pH, Eh, condutividade elétrica, cloreto, sílica, fosfato, K, Na, Ca, Mg, Fe, F, Zn, Ni, Co, Mn, Pb, Cu, Cr, Li e Cd nas águas de drenagens de pequeno porte no nordeste do Amazonas. As ág...

The Andes Cordillera contains the most diverse cryosphere on Earth, including extensive areas covered by seasonal snow, numerous tropical and extratropical glaciers, and many mountain permafrost landforms. Here, we revie...

Downscaling is a critical step to bridge the gap between large-scale climate information and local-scale impact assessments. However, steep and complex mountainous terrain induces highly heterogeneous local-scale meteoro...

This paper attempts to design statistical models to forecast annual precipitation in the Neuquen and Limay river basins in the Comahue region of Argentina. These forecasts are especially useful as they are used to better...

Capybaras (Hydrochoerus hydrochaeris) have been used in Argentina since pre-Columbian times as a source of hide, meat, and fat. Hide is the most valuable capybara by-product and, at present, represents the major hunting ...

This research was carried out in three of the most important basins of the Colombian Amazon (Upper Solimões, Iça and Japurá Rivers). The creeks and lakes that were studied contain abundant diatom species, particularly...

Abstract This study used information about Procamallanus (Spirocamallanus) inopinatus Travassos, Artigas & Pereira, 1928 that had been published over a period of more than 90 years to investigate the infection and distri...

Abstract Glacier mass loss is a primary contributor to sea‐level rise. All prior assessments assume all glacial melt water reaches the ocean, but many mountain glaciers are located far from oceans and may be affected b...

Fluvial basins located on the NE side of the Sierra de Aconquija and facing the Tafí valley (NW Argentina) enable a study of the sedimentary records of valleys and alluvial fans that have been subject to glacial and per...

Notochthamalus scabrosus (Darwin 1854) is commonly attached to littoral rocks and shells, often associated with Notobalanus flosculus (Darwin 1854), and sometimes with Chthamalus cirratus (Darwin 1851). Notochthamalus sc...

Here we present the first use of calcareous microfossils to examine the late Quaternary paleoecology of the endorheic Pozuelos Basin (Argentina). Modern deposition in the basin centers on Laguna de los Pozuelos (LP),a s...

The tectonically active broken foreland of NW Argentina is a recent analog of the eastern margin of the Puna plateau during Mio-Pliocene times and likely of other broken forelands worldwide. In order to evaluate active t...

The Guañacos fold and thrust belt, located between 37° and 38° S in the eastern foothills of the Main Andes is characterized at its eastern border by a series of NE, NW and N- neotectonic faults associated with the An...
