Variability in ostracod communities (Crustacea, Ostracoda) in connected and isolated tropical floodplain lakes [PDF]

, 2017
Floodplains mostly consist of primary and secondary riverbeds, connecting channels and lakes that are either isolated from rivers and channels for most of the year, or lakes that are connected to rivers and channels for most (or all) of the year.

Elements of the Structure of Macrophyte Metacommunities in Coastal Wetlands: Relationships With Limnological and Climatic Variables

Ecological Research, Volume 41, Issue 2, March 2026.
We applied the Elements of Metacommunity Structure (EMS) framework to macrophyte communities across coastal wetlands in southern Brazil, identifying distinct distribution patterns among functional groups. Our results show that environmental and climatic factors shape these patterns differently, with emergent species forming Clementsian communities and ...

Preliminary Report on the Fishes of the Upper Saline River, Polk and Howard Counties, Arkansas, and Observations on Their Relationships with Land Use and Physiochemical Conditions [PDF]

, 1981
The Saline River of southwest Arkansas was impounded by Dierks Lake in 1975. Intensive collecting efforts were made in the river system above Dierks Lake during March, April, and May 1980.

Temporal Beta Diversity of Local Zooplankton Communities in Small Reservoirs is Associated With Hydrological Seasonality

Freshwater Biology, Volume 71, Issue 1, January 2026.
ABSTRACT The variation in local community structure over time—temporal beta diversity—is likely to depend on drivers similar to those used to explain spatial beta diversity. For example, in parallel with the expected relationship between geographic distance and spatial beta diversity, the longer the time between two sampling campaigns, the higher the ...

Unveiling Zooplankton Diversity Patterns: The Differential Influence of Macrophyte Belts on Species and Functional Metrics

Diversity
Species and functional diversity are essential frameworks for analyzing changes in planktonic communities. In lakes and rivers, macrophytes within the coastal zone are a primary determinant of zooplankton community structure and function.

Food resource used by small-sized fish in macrophyte patches in ponds of the upper Paraná river floodplain - DOI: 10.4025/actascibiolsci.v31i2.3266

Acta Scientiarum: Biological Sciences, 2009
This study analyzed the diet of seven small-sized fish species (Characidae) and assessed their use of food resources. The species were collected in 2001 from nine ponds with aquatic macrophytes in the Paraná river floodplain, Brazil. Astyanax altiparanae,

Spatial and temporal distribution patterns of zooplankton (Rotifera, Cladocera, Copepoda) in the water bodies of the Floodplain Gemenc (Duna-Dráva National Park, Hungary) [PDF]

, 2008
The Gemenc Floodplain, situated between the 1498th and 1470th river-kilometres of the River Danube, is part of the Danube–Dráva National Park in Hungary.

Epilithic Algal and Meiofaunal Assemblages of Arctic/Alpine Lakes and Streams Along Latitudinal and Environmental Gradients in Scandinavia

Freshwater Biology, Volume 71, Issue 1, January 2026.
ABSTRACT Epilithic biofilms along a latitudinal gradient of Arctic/alpine lakes and streams were analysed for their composition of algae (incl. cyanobacteria) and meiofaunal assemblages and correlated these with environmental variables. The composition of algal, meiofauna and nematode assemblages differed between lakes and streams.

Bioindicators of climate and trophic state in lowland and highland aquatic ecosystems of the Northern Neotropics

Revista de Biología Tropical, 2013
Chironomids, diatoms and microcrustaceans that inhabit aquatic ecosystems of the Northern Neotropics are abundant and diverse. Some species are highly sensitive to changes in water chemical composition and trophic state.
