The middle Brazos River, located in east-central Texas, is a meandering lowland river with many oxbow lakes on its flood plain. Flood dynamics of the Brazos River are aseasonal, and faunal exchange during lateral connections of the main river channel and oxbows is pulse-like and occurs only during floods that may be months or years apart. Patterns of resource use among sympatric gar species (Le...

Diatoms are valuable bioindicators and their traditional classification identification mainly based on the morphological characteristics of frustules. However, in recent years, DNA-based methods have been proposed rapidly growing scientific literature as a complementary tool to assess ecological status freshwaters. Diatom-based assessment uses indices calculated from sensitivity tolerance value...

Abstract In the present study, meandering behavior of Barak River (Cachar), Assam was traced. Flow path length, meander neck sinuosity index, and river migration were determined segment-by-segment to demonstrate morphological changes. Decadal land-use land cover (LULC) maps also prepared at section scale using Landsat data (1990–2020) validated with Kappa coefficient characterize changes along ...

The effectiveness of protected areas in maintaining biodiversity is increasingly under debate. Specifically, the responses animal populations freshwater ecosystems to disturbances outside are not well understood. Fish assemblages can serve as an indicator such responses. We used dry season oxbow lake fish occurrence data implemented within a Measurement Biodiversity framework examine influence ...

Floods are one of the major hazards worldwide. They are the source of huge risks in rural and urban areas, resulting in severe impacts on the civil society, industry and the economy. The Elbe River has suffered from many severe floods during recent decades. In this study, the zones flooded during 2011 were analyzed using TerraSAR-X images and a digital elevation model for the area in order to i...
