Results and perspectives of fish population studies in the central lake-river system of the Meschera lowland

open access: yesТрансформация экосистем, 2018
The study presents results of studies of fish fauna inhabiting the central lake-river system of the Meschera lowland. It includes the following structural elements: river Buzha, Klepiki (Great) lakes, river Pra, supplementary system of river Pra ...

A snapshot of the limnological features in tropical floodplain lakes: the relative influence of climate and land use

open access: yesActa Limnologica Brasiliensia, 2019
Aim This study aimed to investigate the relative influence of climate (temperature and precipitation) and land use on limnological features of 30 floodplain lakes in the Araguaia River, in Central Brazil, an important river that drains in the Brazilian ...

Paleohydrological changes in an Amazonian floodplain lake: Santa Ninha Lake

open access: yesJournal of Paleolimnology, 2012
Holocene environments have been reconstructed by sedimentological, mineralogical and organic geochemical analysis of a 270-cm core from Santa Ninha Lake, a floodplain lake in lower Amazonia. Dated by fourteen AMS-radiocarbon dates, the sediment core has a basal age of 5,600 cal years BP and different sedimentary units were identified.

Assessment of mercury enrichment in lake sediment records from Alberta Oil Sands development via fluvial and atmospheric pathways

open access: yesFrontiers in Environmental Science, 2022
Exploitation of bitumen-rich deposits in the Alberta Oil Sands Region (AOSR) by large-scale mining and processing activities has generated widespread concern about the potential for dispersal of harmful contaminants to aquatic ecosystems via fluvial and ...

Richness and composition of macrophyte assemblages in four Amazonian lakes - doi: 10.4025/actascibiolsci.v35i3.11602

open access: yesActa Scientiarum: Biological Sciences, 2013
Aquatic macrophytes are an important component in the structure of lakes in Neotropical floodplains, for example, because they support a high diversity of invertebrates and vertebrates.

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 ...

The importance of oxbow lakes in the floodplain storage of pollutants [PDF]

open access: yesGeology, 2021
Abstract Oxbow lakes are important stores for fine-grained sediment, which potentially makes them critical sinks for sediment-associated pollutants. We leverage an exhaustive public archive of coring data, supplemented by our data collection, to provide a quantitative assessment of the role of oxbows as off-channel sinks. We investigated

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.

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

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.
