Shifts between alternative stable states have become a focus of research in temperate
shallow lakes. Here we show that sharp transitions between a clear, macrophyte-dominated …

Hydrological variability over seasonal and multi-annual timescales strongly shapes the
ecological structure and functioning of floodplain ecosystems. The current IPCC climate …

Floodplain lakes are ecosystems characterised by annual flood and dry cycles. Fish ecology
is influenced by the flood pulse due to the large influx of allochthonous food resources and …

Lakes play an important role in biogeochemical, ecological and hydrological processes in
the river-floodplain system. The aim of this study was to evaluate the dynamics of the …

High-resolution satellite images, digital elevation models, bathymetric and sedimentological
surveys coupled with statistical analysis were used to understand the physical environment …

Abstract Chlorophyll-a (Chl-a) has been widely used in the assessment and monitoring of
aquatic environments. Local and regional factors can influence Chl-a concentrations; …

AIM: The aim of this work was to study the diel stratification parameters temperature,
dissolved oxygen and conductivity, providing a more detailed description of a friagem event …

AIM: There is currently no consensus regarding the physical and chemical variability of
tropical reservoirs. In semiarid Northeastern Brazil, reservoirs are among other things used …

AIMS: The present study aimed at a morphological characterization of 18 lakes of the
municipalities of Cidreira, Balneário Pinhal and Palmares do Sul, situated in the northern …

Regime shifts in shallow lakes are often associated with anthropogenic impacts, such as
land-use change, non-point source nutrient loading, and overfishing. These shifts have …
