The relationship between zooplankton occupancy and abundance in a floodplain is mediated by the hydrological regime [PDF]

open access: yesActa Limnologica Brasiliensia, 2022
: Aim Positive relationships between occupancy and abundance are often found for different groups of organisms and ecosystem types. However, to our knowledge, no study has sought to assess this relationship considering a context in which a particular ...

Modeling the Ecological Responses of Tree Species to the Flood Pulse of the Amazon Negro River Floodplains

open access: yesFrontiers in Ecology and Evolution, 2021
The large flood pulse of the Amazon basin is a principal driver of environmental heterogeneity with important implications for ecosystem function and the assembly of natural communities.

Drastic decline of flood pulse in the Cambodian floodplains (Mekong River and Tonle Sap system) [PDF]

open access: yesHydrology and Earth System Sciences, 2022
The Cambodian floodplains experience a yearly flood pulse that is essential to sustain fisheries and the agricultural calendar. Sixty years of data, from 1960–2019, are used to track the changes to the flood pulse there. We find that minimum water levels

FLOOD-PULSE AND RIVERSCAPE DYNAMICS IN A BRAIDED GLACIAL RIVER [PDF]

open access: yesEcology, 2006
River ecosystems are increasingly viewed as dynamic riverscapes; their extent, composition, and configuration vary in response to the pulsing of discharge. Although compositional and configurational shifts in riverscapes are thought to control ecosystem processes and biodiversity, attempts to quantify riverscape dynamics of braided rivers are scarce ...

Influence of the flood pulse on the reproduction of Tocantinsia piresi (Miranda Ribeiro) and Auchenipterus nuchalis (Spix & Agassiz) (Auchenipteridae) of the middle Xingu River, Brazil [PDF]

open access: yesBrazilian Journal of Biology, 2015
This study investigates the influence of the flood pulse on the reproductive biology of the auchenipterids Tocantisia piresi (Miranda Ribeiro, 1920) and Auchenipterus nuchalis (Spix & Agassiz, 1829) from the middle Xingu River in the Brazilian state of ...

The effect of seasonality on the structure of rotifers in a black-water shallow lake in Central Amazonia

open access: yesAnais da Academia Brasileira de Ciências, 2014
Rotifers have often been used as indicators of sudden changes in physical and chemical features of the aquatic environment. Such features vary greatly during flood pulse events in small lakes connected to major floodplains.

Flooding characteristics in pulsed packed extraction columns [PDF]

open access: yesBrazilian Journal of Chemical Engineering, 2011
Flooding behavior of a 76.2 mm diameter pulsed packed column has been determined using four different liquid-liquid systems. The effects of pulsation intensity, flow ratio, interfacial tension, and packing geometry on flood point have been investigated. The results showed that the maximum throughput of the column decreases with an increase in pulsation

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

Investigation of dry-wet cycles effect on the durability of modified rubberised concrete

open access: yesForces in Mechanics, 2023
For communities and property in flood-prone locations, the performance of construction materials during flood occurrences is important. Limited investigations are available on the influence of dry-wet water cycles on rubberised concrete after rubber ...

Vegetation, rainfall, and pulsing hydrology in the Pantanal, the world’s largest tropical wetland

open access: yesEnvironmental Research Letters, 2019
Wetlands provide valuable ecosystem services and play a central role in global carbon cycling. Changes in rainfall and the flood-pulse are likely to disrupt the processes that maintain these landscapes; further, landscape modification may dramatically ...
