Discharge estimation in a backwater affected meandering river [PDF]

, 2011
Variable effects of backwaters complicate the development of rating curves at hydrometric measurement stations. In areas influenced by backwater, single-parameter rating curve techniques are often inapplicable.

The Nature Restoration Regulation and the Water Framework Directive: enhancing restoration of freshwater ecosystems, or muddying the waters?

Restoration Ecology, EarlyView.
The Water Framework Directive 2000/60/EC (WFD) and the Nature Restoration Regulation (EU) 2024/1991 (NRR) both require Member States to restore freshwater ecosystems. This study analyzes how these two instruments interact, identifying both synergies and conflicts.

Impacts of reclamation and aquaculture on the wintering waterbird assemblage at a floodplain lakeshore based on multidimensional diversity

Global Ecology and Conservation
The floodplain lakeshores have pronounced hydrological and topographical gradients, high habitat heterogeneity, and abundant food sources, providing suitable habitats for wintering and stopping waterbirds.

Fish fauna structure and composition in an isolated lake in the Middle Araguaia River floodplain, Mato Grosso – Brazil [PDF]

Biotemas, 2012
Studies dealing with fish fauna in floodplain lakes of the Araguaia River basin are limited, and have mostly focused on lakes that are directly connected to the main river and are heavily influenced by the flood pulse.

Effects of restoration on macrophyte and macroinvertebrate ecological status and biodiversity in lowland streams in Denmark

Restoration Ecology, EarlyView.
Abstract Introduction Habitat restoration is applied to promote ecological recovery in degraded freshwater systems. However, it remains unclear whether stream restoration measures enhance Water Framework Directive (WFD) ecological status and biodiversity.

Microbial mats in dinosaur ichnocoenoses

Sedimentology, EarlyView.
ABSTRACT Until now, the significance of microbial mats in preservation of dinosaur tracks and in reconstructing the palaeoenvironment in which dinosaurs roamed was rarely studied. Dinosaur tracks are commonly found close to ancient aquatic bodies where moist sediment had once allowed footstep registration.

About the relationship between the zooplankton and fluctuating water levels of Lago Camaleão, a Central Amazonian várzea lake

, 1984
A two-year study of the composition and abundance of the zooplankton was conducted in an Amazonian vãrzea lake, Lago Camaleão. Rotifers were dominant in terms of both species numbers and density.

MISS diversity from saline lakes of Brazilian Pantanal: Origin, potential of preservation and comparison with examples of the Ediacaran‐Cambrian shallow depositional settings

Sedimentology, EarlyView.
ABSTRACT One of the largest wetlands on Earth, the Brazilian Pantanal contains roughly 10 000 natural lakes, about 1000 of which are hypersaline. In these environmentally stressful settings, animal life struggles to survive, while cyanobacteria form extensive mats.
