Methane turnover in exposed sediments of an Amazon floodplain lake

Biogeochemistry, 2000
In the Amazon floodplain large areas of unvegetatedlake sediments are exposed to air during low water. Imeasured methane fluxes from exposed sediments of anAmazonian floodplain lake and assessed the regulatingfactors. Methane emission decreased from values between 10 and 40 μmol CH4 mminus 2 hminus 1to zero when the sediments were exposed to air ...

Fast response of lake plankton and nutrients to river inundations on floodplain lakes

River Research and Applications, 2008
AbstractKey variables in ecosystems tend to operate on widely different time‐scales. These time‐scales become relevant when a disturbance rocks the ecosystem. Here we try to explain the fast dynamics of plankton and nutrients in the water column of floodplain lakes after disturbances (inundations).

Nitrogen Turnover in Drying Sediments of an Amazon Floodplain Lake

Microbial Ecology, 2005
In the Amazon floodplain large areas are subject to annual cycles of drying and rewetting. The turnover of nitrogen in the periodically drying sediments is an important regulator of floodplain fertility. In the present study the transition of a lake sediment from flooded to dry conditions was studied with respect to microbial nitrogen turnover.

Biogeochemistry of Amazon Floodplain Lakes and Associated Wetlands

2001
Floodplains and associated lakes are important components of the biogeochemistry, ecology, and hydrology of the Amazon basin. Amazon floodplains contain thousands of lakes and associated wetlands linked to each other and to the many rivers of the immense basin. These floodplain lakes modify the passage of flood waves (Richey et al.

Remote sensing of lakes and floodplains in the Amazon basin

Remote Sensing Reviews, 1994
Abstract Remote sensing of the lakes and floodplains in the Amazon basin has provided quantitative information on open water, floating macrophytes and flooded forests, and regional inundation. Side‐looking airborne radar (X‐band) imagery permitted measurement of lake shapes and areas. Satellite altimeters permitted estimation of stage for large rivers.

Hydrological control of system characteristics of floodplain lakes

Ecohydrology & Hydrobiology, 2006
Abstract Water bodies within floodplains are strongly governed by their hydrological connectivity with the main river (Heiler et al. 1995). Connectivity is decisive for the general ecosystem characteristics and the balance between input and output of nutrients and organic carbon sources.

The evolution of an oxbow lake in the Mississippi alluvial floodplain

Journal of Soil and Water Conservation, 2008
The history of sediment accumulation in an oxbow lake located on the Mississippi alluvial floodplain was reconstructed based on sedimentation rates determined using 14C activities from bulk sediment fractions and from 210Pb and 137Cs measurements. Higher rates of sediment accumulation consistent with frequent flooding when first abandoned 3,800 to 5 ...
