Too Hot, Too Cold, Just Right: Thermal Modulating Capacity of Different Sources of Groundwater Discharge to Salmon‐Bearing Streams

River Research and Applications, EarlyView.
ABSTRACT Groundwater discharge plays a key role in maintaining habitat suitability for cold‐water fish by generating streamflow and modulating temperatures. However, the thermal influence depends on groundwater source depth and how far groundwater travels from the point of discharge to a receiving stream.

Diversity and syntaxonomy of aquatic macrophyte communities in floodplain lakes of the Middle Ob River (Tomsk Carbon Polygon, Western Siberia)

Acta Biologica Sibirica
The floodplain of the Ob River, one of the largest wetland systems in Eurasia, plays a significant role in the regional carbon cycle, yet its aquatic macrophyte communities remain poorly studied.

Copepod assemblage structure (Crustacea: Copepoda) along a longitudinal environmental gradient in a tropical river-floodplain system, Brazil

Acta Limnologica Brasiliensia, 2017
Aim: In this study, we analyzed the structure of the copepod community along a longitudinal axis of the last undammed stretch of the Upper Paraná River floodplain, downstream of Porto Primavera reservoir. We hypothesized that (i) copepod assemblage would

Environmental Stressors Influence Spatial Complexity in a Fluvial Macrophyte meadow

Remote Sensing in Ecology and Conservation, EarlyView.
This research investigates the nonlinear relationships between environmental stressors and the fine‐scale spatial complexity of a fluvial macrophytes meadow. The use of multivariate spatial analysis allowed us to identify two major environmental gradients (nutrients and light) and two major complexity gradients (related to abundance and fragmentation).

Limnology in the Upper Paraná River floodplain: large-scale spatial and temporal patterns, and the influence of reservoirs

Brazilian Journal of Biology
Knowledge of abiotic limnological factors is important to monitor changes caused by humans, and to explain the structure and dynamics of populations and communities in a variety of inland water ecosystems.

Spatial and seasonal contrasts of sedimentary organic matter in floodplain lakes of the central Amazon basin [PDF]

Biogeosciences, 2016
In this study, we investigated the seasonal and spatial pattern of sedimentary organic matter (SOM) in five floodplain lakes of the central Amazon basin (Cabaliana, Janauaca, Canaçari, Mirituba and Curuai) which have different morphologies, hydrodynamics

Remote Sensing‐Based Identification of Habitat Loss for Herbivorous Waterbirds Driven by Wetland Inundation Alterations

Remote Sensing in Ecology and Conservation, EarlyView.
We present a deep learning framework integrating remote sensing and SHAP interpretation to map 22‐year habitat dynamics of herbivorous waterbirds in Dongting Lake. Results show nearly 50% habitat loss, driven primarily by hydrological recession timing rather than static inundation extent.

Connectivity patterns between floodplain lakes and neighboring streams in the historical floodplain of the Lower Mississippi River

Ecological Indicators
Hydrologic connectivity, the network of water pathways linking aquatic habitats, is vital for the exchange of organisms and abiotic materials between rivers and adjacent waterbodies.

‘Using anuran community diversity and Pseudacris crucifer to predict landscape quality across a land use gradient'

Wildlife Biology, EarlyView.
As human‐modified landscape and climate changes proliferate, maintaining biodiversity and understanding the function and quality of available habitat is imperative. As anurans (frogs/toads) such as Pseudacris crucifer, can be an indicator species of habitat quality and ecosystem productivity, studying the anuran community in a mixed‐land use region ...

Richness, abundance and microhabitat use by Ardeidae (Aves: Pelecaniformes) during one seasonal cycle in the floodplain lakesof the lower Amazon River [PDF]

Zoologia (Curitiba), 2019
The Amazon floodplains become periodically submerged as result of seasonal changes in the water levels throughout the year. These changes influence the availability of microhabitats and consequently the abundance of organisms in these ecosystems. In this
