Environmental managers need information to quickly detect which stressor combinations
should be addressed to reverse river degradation across large study areas. The pivotal role …

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 …

Large dams regulate river hydrology and influence water chemistry, sediment dynamics,
channel form and biotic communities. These effects may translate into important changes in …

Human activity has caused longitudinal fragmentation of many rivers. Fishways have been
installed worldwide, but their successive use by potamodromous species remains poorly …

Biological invasions are a major factor for biodiversity loss, particularly in freshwater
environments. Largemouth bass Micropterus salmoides is native to North America and is …

Over the last decade the development of small hydropower projects has been one of the
most active areas of the energy sector. One of the main environmental challenges faced by …

Throughout Europe in the last decade there has been a steady shift away from more
technical fish pass designs to more nature‐like passes, such as nature‐like bypass …

The effects of river regulation on the hydrological cycle of a river and on the respective fish
assemblage may differ according to dam operation purpose and type of river analysed. To …

River regulation for hydroelectricity production results in rapid changes of flow and habitat
features, but its effects in the movement patterns of freshwater fish are not well understood …

The disruption of longitudinal connectivity caused by artificial barriers in rivers is considered
to be a major threat to freshwater fish communities at the global scale. In Portugal, the …
