1. We used field surveys to compare the density and mesohabitat-scale distribution of the native coastrange sculpin (Cottus aleuticus) and the prickly sculpin (C. asper) in coastal rivers in north-western California, U.S.A., with and without an introduced piscivorous fish, the Sacramento pikeminnow, Ptychocheilus grandis. We also measured mortality of tethered prickly sculpin in a field experim...

Climate and land-use changes are leading to impacts on individual ecosystems as well shifts in transfer dynamics between interconnected systems. At the land-ocean interface, riverine inputs of organic matter (OM) nutrients have potential lead coastal carbon nutrient cycling with consequences for ecosystem structure function. In this study, we assess OM two contrasting Norwegian river-to-fjord s...

Abstract Rivers and their surrounding land provide resources services that result in trade-offs requiring legislative institutional interventions, for which the perspectives of law-policymakers societal values political expediencies play a major role decision-making. This study critically evaluates evolving land–river governance large democratically elected governments with complex developmenta...

RVR Meander was developed as a toolbox for modeling restoration and naturalization processes in rivers. This model includes Windows-based and Geographical Information System-based programs for analyzing and modeling planform migration of streams. In the past, several rivers have been channelized causing environmental and ecological problems. Restoration techniques evolve as natural solutions to...

Sediment transfer from continents to oceans via rivers is one of the important processes regulating river-bank stabilization, soil formation, biogeochemical cycling of elements, crust evolution and many other earth-related processes. Due to changes in continental positions during the geologic past, water flow and sediment loads in rivers have also shown variations during different time periods....

River Res Applic. 2017;1–13. Abstract The transport of water and sediment from rivers to adjacent floodplains helps generate complex floodplain, wetland, and riparian ecosystems. However, riverside levees restrict lateral connectivity of water and sediment during flood pulses, making the re‐introduction of floodplain hydrogeomorphic processes through intentional levee breaching and removal an e...

1. We examined the influence of hydrologic seasonality on temporal variation of planktonic bacterial production (BP) in relatively undisturbed lowland rivers of the middle Orinoco basin, Venezuela. We sampled two clearwater and two blackwater rivers over 2 years for dissolved organic carbon (DOC), chlorophyll, phosphorus and bacterial abundance to determine their relationship to temporal variat...

Preface The Healthy Rivers Commission has completed investigations of the coastal catchments of rivers and lakes as referred to it by the NSW Government since 1995. Lessons learnt from those Inquiries have led the Commission to establish a number of key principles and strategies, which it believes are essential to achieving healthy rivers, lakes and catchments. This document advances a vision f...
