Response of Avian Communities in Large-river Floodplains to Environmental Variation at Multiple Scales
Large-river floodplains have been subjected to profound human-caused alteration, but subsequent effects on landbirds in these habitats are largely unknown. To assess the extent to which landscape measures might serve as ecological indicators in these systems, we examined patterns of habitat use by forest birds along a 380-km stretch of the Wisconsin River, USA. We surveyed forest bird communiti...
متن کاملMonitoring Vegetation Biomass in River Floodplains Using Imaging Spectroscopy
For optimal management of river floodplains in the Netherlands monitoring of natural vegetation succession and hydrodynamic processes is essential. A key biophysical parameter to monitor floodplains is vegetation biomass. Not only because it influences the hydraulic resistance determining the discharge capacity of the floodplains, but also indicating species diversity and habitat heterogeneity ...
متن کاملUnsteady 1D flow model of a river with partly vegetated floodplains - application to the Rhine River
A relatively simple unsteady flow model was proposed which estimates velocities, friction factors and the components of discharge in the main channel and on the floodplains simultaneously. Bottom roughness of the main channel and the floodplains, the flow resistance of vegetation on the floodplains and the flow resistance caused by the momentum transfer between the main channel and the floodpla...
متن کاملPossibilities of visible–near-infrared spectroscopy for the assessment of soil contamination in river floodplains
During the past decades, large amounts of diffuse cadmium (Cd) and zinc (Zn) contaminated soil material have been deposited in the floodplains of the river Rhine in the Netherlands. As spatial information on soil quality is required at different scale levels covering the whole area, characterisation exclusively based on soil sampling and analysis is time-consuming and very expensive. A quicker ...
متن کاملGravel-bed river floodplains are the ecological nexus of glaciated mountain landscapes
Gravel-bed river floodplains in mountain landscapes disproportionately concentrate diverse habitats, nutrient cycling, productivity of biota, and species interactions. Although stream ecologists know that river channel and floodplain habitats used by aquatic organisms are maintained by hydrologic regimes that mobilize gravel-bed sediments, terrestrial ecologists have largely been unaware of the...
