Parana River morphodynamics in the context of climate change
International Journal of River Basin Management, 2013 ABSTRACTThis paper presents an analysis of the sediment dynamics that takes place at different scales within the Middle and the Lower Parana River in the La Plata Basin. The aim of this study is to provide a multi-disciplinary and multi-scale approach for the prediction of river future morphology in the context of climate change, the intended use of ...

International Journal for Numerical Methods in Fluids, EarlyView.The immersed boundary method (IBM) was coupled with the moment representation lattice Boltzmann method (MR‐LBM), reducing bandwidth requirements compared to population‐based LBM formulations. A systematic assessment of IBM parameters was conducted to quantify their effect on computational performance.

The Drosophila community in xerophytic vegetations of the upper Parana-Paraguay river basin [PDF]
Brazilian Journal of Biology, 2006 The genus Drosophila is the most abundant in the Drosophilidae family. Some species are endemic to certain regions and others are cosmopolitans. In Brazil, there are several ecosystems to explore regarding the composition and ecological aspects of Drosophila. Xerophytic areas are an example.

People and Nature, EarlyView.Abstract Ecoregions are often defined based on homogeneous biophysical and ecological conditions and are optimal spatial units for designing conservation strategies. However, transboundary ecoregions such as the Alto Paraná Atlantic Forest (APAF) experience asymmetrical conservation outcomes, understood here as cross‐border differences, resulting from ...
