Organic carbon and nitrogen export from a tropical dam-impacted floodplain system [PDF]
, 2013 Tropical floodplains play an important role in organic matter transport, storage, and transformation between headwaters and oceans. However, the fluxes and quality of organic carbon (OC) and organic nitrogen (ON) in tropical river-floodplain systems are ...

A floristic survey of angiosperm species occurring at three landscapes of the Central Amazon várzea, Brazil [PDF]
Check List, 2015 The Amazonian floodplains harbor highly diverse wetland forests, with angiosperms adapted to survive extreme floods and droughts. About 14% of the Amazon Basin is covered by floodplains, which are fundamental to river productivity, biogeochemical cycling

Carbon accumulation in Amazonian floodplain lakes: A significant component of Amazon budgets?
Limnology and Oceanography Letters, 2017 The Amazon floodplains cover approximately 10% of the Amazon Basin and are composed of predominantly anoxic sediments that may store large amounts of carbon. Our study combines 210Pb derived sedimentation rates from four recently analyzed sediment cores (

Linking Flow Regime, Floodplain Lake Connectivity and Fish Catch in a Large River-Floodplain System, the Volga-Akhtuba Floodplain (Russian Federation) [PDF]
, 2011 River-floodplain systems are amongst the most productive—but often severely impacted—aquatic systems worldwide. We explored the ecological response of fish to flow regime in a large river-floodplain system by studying the relationships between (1 ...

Expressive fluxes over Amazon floodplain revealed by 2D hydrodynamic modelling [PDF]
, 2023 Water fluxes in the Amazon River floodplain affect hydrodynamic and ecological processes from local to global scales, but they remain poorly understood due to difficult accessibility and limited data.
