In the Amazon, the world's largest river basin, migrations within freshwater habitats are one
of the predominant life history strategies for fishes. The flood pulse and the extensive river …

Abstract Lateral Hydrological Connectivity (LHC) has been extensively fragmented in river–
floodplain ecosystems of the world. Uncertainties about how LHC affects fishes are great …

Abnormal hydroclimatic years in the Amazon have been increasingly frequent in the last two
decades, creating more prolonged droughts and severe floods. These events are expected …

The seasonality of tropical rivers, induced mainly by water level changes, shapes many
interrelated aspects of ecological communities and the populations they contain, including …

Dynamic flow regimes maintain critical connections between main channel and adjacent
floodplain habitats that provide fish access to shelter, foraging, and spawning opportunities …

Visual adaptations can stem from variations in amino acid composition, chromophore
utilization, and differential opsin gene expression levels, enabling individuals to adjust their …

Despite the high number of fish species described for the Amazon region, the ichthyofauna
that inhabits the depths of the main channels of large tropical rivers is one of the least …

Colourful signals are usually honest indicators of mate quality since they are energetically
costly. However, how colours are perceived by choosers is highly affected by the …

Hydrology and temperature are known as key drivers for fish migration in floodplain-channel
systems of large rivers. The Lower Irtysh contains valuable species of whitefish and …

Wallacean shortfalls in knowledge about biodiversity, especially in the Amazon biome, can
only be addressed by increasing sampling efforts in focal areas. The objective of this study …
