Fisheries governance in the 21 st century: barriers and opportunities in South American large rivers
(Food and Agriculture Organization, 2016)
South American large-river fisheries are experiencing a growing pressure due to mining activity, construction of dams, water diversion, dredging, commercial overfishing, pollution, floodplain deterioration, agriculture, ...
Patterns of anabranching channels: the ultimate end-member adjustment of mega rivers
(Elsevier Science, 2008-10)
Large fluvial systems adjust to a combination of controls to form distinctive channels, which represent a dominant factor in the evolution of floodplain geomorphology and sedimentology. Fluvial geomorphology has commonly ...
Extreme discharge events in the Paraná River and their climate forcing
(Elsevier Science, 2003-07-25)
The largest discharge anomalies of the Paraná River were examined focusing on the contribution from the sub-basins and on the climate forcing of these events. Major discharge anomalies at Corrientes originated in the central ...
Diatom-based inference model for conductivity reconstructions in dryland river systems from north Patagonia, Argentina
(Birkhauser Verlag Ag, 2021-07-21)
Dryland river systems support a diverse aquatic biota in semi-arid and arid landscapes, but they are increasingly vulnerable to natural and human impacts. This study provides the first modern diatom training set (n = 38) ...
Study of the distribution of dichlorobenzenes in sediment and water of Suquía River basin (Córdoba-Argentina) by an optimised SPME-GC-MS procedure
(Inderscience Enterprises Ltd, 2009-12)
Three dichlorobenzene isomers (DCBs) were monitored in water and sediment from the Suquía River basin by Solid Phase Microextraction (HS-SPME), coupled to Gas Chromatography-Mass Spectrometry (GC-MS). DCBs were not detected ...
Small mammal remains recovered from two archaeological sites in the middle and lower Negro River valley (Late Holocene, Argentina). Taphonomic issues and paleoenvironmental implications
(Pergamon-Elsevier Science Ltd, 2011-01)
This paper presents the results of a taphonomic and paleoenvironmental analysis of small mammal remains recovered from the Negro Muerto and Angostura 1 archaeological sites. These sites (ca. 0.5 and 0.95 ka BP, respectively), ...
Modern diatoms from a temperate river in South America: the Colorado River (North Patagonia, Argentina)
(Biopress Limited, 2017-04)
Diatom assemblage composition and distribution from surface sediment samples of the Colorado River, Patagonia were analysed in relation to environmental variables using multivariate techniques. The aim of this study was ...
Miniatures as ritual objects: exploring the role of small-sized vessels among the complex late holocene hunter-gatherers from the Paraná river lowlands in South America
(Cambridge University Press, 2020-08)
This study is the first systematic approach to ceramic miniatures from the lowlands of the Paraná River (northeastern Argentina), which have received marginal attention from regional archaeology. This paper presents an ...
Changes in phytoplankton morpho-functional groups induced by extreme hydroclimatic events in the Middle Paraná River (Argentina)
(Springer, 2009-12)
The extreme hydrological fluctuations in the South American Paraná River are unequivocally coupled with ENSO´s global climatic phenomenon. In order to identify phytoplankton changes triggered by extraordinary flood (November ...
Nonlinear dynamics of river runoff elucidated by horizontal visibility graphs
(American Institute of Physics, 2018-07)
Horizontal Visibility Graphs (HVGs) are a recently developed method to construct networks from time series. The values of the time series are considered as the nodes of the network and are linked to each other if there is ...
