Freshwater systems are severely impacted by connectivity reduction due to the construction
of dams and weirs. The breach of this longitudinal connectivity imperils freshwater fish …

River fragmentation due to artificial barriers directly impacts fish communities by limiting
migratory movements. This work aims to understand how small barriers affect the …

The effects of hydropeaking in the habitat of the Iberian barbel (Luciobarbus bocagei) a
native cyprinid fish species of the Iberian Peninsula, were investigated. Two study sites were …

The presence of small weirs, far more numerous than dams, has increased habitat
fragmentation on rivers worldwide. This study aims to evaluate the upstream passage …

Throughout their lives, fish accomplish frequent movements between functional habitats that
are often triggered by environmental signals. We aimed to determine if rheophilic cyprinids …

Endemic freshwater fish from the Mediterranean region are among the most threatened
species in the world owing to increasing river degradation. Because of such threats, the …

Identifying the environmental gradients that control the functional structure of biological
assemblages in reference conditions is fundamental to help river management and predict …

Both water managers and researchers have the same goal when it comes to fish
conservation, namely, to sustain, to improve or to restore aquatic habitat. To this aim, two …

This study aims to describe pre-reproductive movements of Luciobarbus bocagei and
Pseudochondrostoma duriense in a regulated canyon-stretch of the Tormes River (Spain) …

Fragmentation of freshwater systems is one of the more common human‐induced impacts
on the environment, and one of the most dramatic because it leads to disconnections among …
