Carbon sedimentation in shallow floodplain lakes [PDF]

open access: yesLimnology and Oceanography
AbstractShallow lakes are increasingly recognized as important sites for organic carbon (OC) storage. However, the drivers of OC deposition in shallow floodplain lakes remain unclear due to complex terrestrial and aquatic interactions. Using 8 yr of monthly sediment trap data in a cross‐ecosystem experiment on six UK shallow lakes of varying riverine ...

Flood did not cause the taxonomic and functional homogenization of Chironomidae (Diptera) community in a Neotropical floodplain [PDF]

open access: yesActa Limnologica Brasiliensia
: Aim We investigated the hypothesis that flood decreases the taxonomic and functional beta diversity of Chironomidae (Diptera) larvae among floodplain lakes, causing biotic homogenization. Methods We collected benthic samples using a modified Petersen

Spatial Expansion of Human Settlement during the Longshan Period (~4.5–~3.9 ka BP) and Its Hydroclimatic Contexts in the Lower Yellow River Floodplain, Eastern China

open access: yesLand, 2021
Obvious spatial expansion of human settlement occurred in the lower Yellow River floodplain during the Longshan period, but the external factors driving this expansion remain unclear.

Evaluation of environmental condition: water and sediment examination of oxbow lakes [PDF]

open access: yesActa Geographica Debrecina. Landscape & Environment Series, 2011
As a result of the river regulation a number of oxbow lakes have arisen in the floodplain of the Lower-Tisza. The floodplain lakes represent natural values and major recreation areas of the lowland region.

Seepage exchange in an Amazon floodplain lake [PDF]

open access: yesLimnology and Oceanography, 1995
Exchange of water between the lake and the surrounding groundwater system was computed for a permanent lake on the central Amazon floodplain (Lake Calado) from an empirical seepage model incorporating 240 direct measurements of seepage from the lakebed and seasonal changes in lake stage and morphometry.

Interconnectedness during high water maintains similarity in fish assemblages of island floodplain lakes in the Amazonian Basin

open access: yesZoologia (Curitiba), 2010
We conducted a study to test the hypothesis that interconnectedness among island floodplain lakes and the adjacent Solimões River during the flood stage of the hydrologic cycle is enough to maintain similarity in fish species assemblages.

The Catfish Fishing in the Amazon Floodplain Lakes [PDF]

open access: yesOceanography & Fisheries Open access Journal, 2018
This study is about the spatial and temporal variability of the Hypophthalmus catfish fishery in the Amazonian floodplain lakes and the relationship among commercial CPUE, environmental and economic variables. The fishing productivity varies according to the fishing ground which varies due to the contribution of a set of variables. The most outstanding

Fish species richness is associated with the availability of landscape components across seasons in the Amazonian floodplain [PDF]

open access: yesPeerJ, 2018
Understanding environmental biodiversity drivers in freshwater systems continues to be a fundamental challenge in studies of their fish assemblages. The present study seeks to determine the degree to which landscape variables of Amazonian floodplain ...

Relationships between Floodplain Lake Fish Communities and Environmental Variables in a Large River‐Floodplain Ecosystem [PDF]

open access: yesTransactions of the American Fisheries Society, 2008
AbstractFloodplain lakes of large river systems contain fish habitats that are not found elsewhere within the river, and these lakes have a diversity of environmental conditions that vary in space and time. Our objective was to examine relationships between floodplain lake fish communities and environmental variables associated with lake morphology ...

Multispecies Fisheries in the Lower Amazon River and Its Relationship with the Regional and Global Climate Variability.

open access: yesPLoS ONE, 2016
This paper aims to describe the spatial-temporal variability in catch of the main fishery resources of the Amazon River and floodplain lakes of the Lower Amazon, as well as relating the Catch per Unit of Effort with anomalies of some of the Amazon River,
