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

Zoologia (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.

Seepage exchange in an Amazon floodplain lake [PDF]

Limnology 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.

The Catfish Fishing in the Amazon Floodplain Lakes [PDF]

Oceanography & 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

Exploring dynamics of Poyang floodplain lakes using fused 8-day, 30-m remote sensing data (2000–2023)

European Journal of Remote Sensing
Poyang Lake has been frequently affected by droughts, which has drawn increasing attention. Floodplain lakes surrounding the main Poyang Lake play an important role in maintaining the hydrological cycle and supporting ecological diversity. Monitoring the

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

PeerJ, 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 ...

Intraregional variability in chironomid-inferred temperature estimates and the influence of river inundations on lacustrine chironomid assemblages. [PDF]

, 2007
Floodplain lakes are rarely analysed for fossil chironomids and usually not incorporated in modern chironomid-climate calibration datasets because of the potential complex hydrological processes that could result from flooding of the lakes.

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

PLoS 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,

Floodplain management in temperate regions : is multifunctionality enhancing biodiversity? [PDF]

, 2013
Background: Floodplains are among the most diverse, dynamic, productive and populated but also the most threatened ecosystems on Earth. Threats are mainly related to human activities that alter the landscape and disrupt fluvial processes to obtain ...

Using dendroclimatic analysis of exotic deciduous conifers in an arboretum to document tree growth in response to climate change, Northeast Ohio, USA

PLANTS, PEOPLE, PLANET, EarlyView.
Rising temperatures and wetter conditions in the Midcontinent of North America are influencing climate responses in trees. Dendroclimatological analyses of four exotic deciduous conifer species from Secrest Arboretum, Northeast Ohio help identify past, present and future climate‐tree interactions.

Differences in environmental heterogeneity promote the nestedness of Chironomidae metacommunity in Neotropical floodplain lakes

Acta Limnologica Brasiliensia, 2017
Aim: Gradients of environmental heterogeneity perform a strong influence on the distribution of organisms and determine differences in composition, where more physically complex habitats harbor greater species richness than those simpler.
