Investing Hysteresis in Floodplain Dynamics of Lakes in the Middle St. Johns River Using Sentinel-1 SAR Imagery
… to map flood extent in the Middle St. Johns River Lake floodplains and examine the presence of hysteresis during flood events. SAR scenes corresponding to river gauge readings were analyzed from the rising and falling limbs of a flood hydrograph. By comparing these flood maps, we assess …

Cross-Scale Drivers of the Reciprocal Impacts Among Freshwater Mussels, Hydrology, and Floodplains on River Biogeochemistry
Rivers integrate physical, chemical, and biological processes that occur within the watershed. To characterize the functional role of animal species in shaping biogeochemical cycles and resource patterns, therefore, it is necessary to account for variation in watershed features and hydrologic …

Using environmental DNA metabarcoding to monitor fish biodiversity and assess anthropogenic barrier impacts on the river Mersey, UK
… blocking crucial nutrients passing through river systems, and, above all, preventing crucial movements and migrations of aquatic organisms. Fish passes alleviate the problem, increasing river connectivity, but there is an evident need for a better understanding of their efficiency for fish …

ECOLOGICAL AND SOCIOLOGICAL IMPLICATIONS OF TISZA RIVER MINE TAILINGS POLLUTION AND EFFECT OF CHRONIC CADMIUM EXPOSURE ON FISH PHYSIOLOGY
… activities have elevated metal concentrations in river sediments above what would be expected naturally. One of the primary anthropogenic sources of metals in freshwater is contamination by mine tailings, a toxic slurry of waste rock and chemicals left over after ore minerals or coal extraction. …

Stream functional response to mountaintop removal and valley fill coal mining
… which are dependent on temporal and lateral connectivity in river networks. To determine the affect of MTRVF on stream ecosystem function, leaf breakdown, which is an ecosystem level attribute of forested streams, was measured in five streams draining MTRVF sites and five reference streams in …
