Assessing water diversion impacts on the fish community size structure in headwater stream stretches Open
Water diversion for hydropower plants is one of the leading causes of habitat alteration and biotic homogenization. The impacts of small hydropower plants on fish communities are usually assessed using taxonomic composition and structure i…

Retos y oportunidades para la evaluación del estado ecológico en rios temporales Open
Los ríos temporales (RTs) son ecosistemas fluviales en los que los efectos de las perturbaciones antrópicas se mezclan con los de la propia perturbación natural que impone la temporalidad del flujo. A pesar de los avances en el conocimient…

Manual tècnic de conservació i restauració de rius i riberes Open
La vegetació de ribera sempre s’ha entès com un sistema lineal que recorre un curs d’aigua, però quan l’orografia, la dinàmica hidràulica i els usos del sòl ho permeten, aquesta vegetació va més enllà de la galeria, cinyell de les ribes de…

The river forest: conservation, restoration and governance of Mediterranean riparian forests Open
Rivers have their own aquatic and riparian vegetation. This riparian vegetation eventually becomes a forest (the river forest), forming a characteristic strip alongside the course of the river. River forests are highly diverse and complex,…

El bosque de ribera: conservación, restauración y gobernanza de los bosques de ribera mediterráneos Open
Los ríos tienen su propia vegetación, tanto acuática como ribereña. La vegetación de sus orillas acaba transformándose en un bosque, el bosque del río o de ribera, y formando una franja típica a lo largo de su trayecto. Los bosques de ribe…

Why and when do freshwater fish migrate? Observations of migration patterns of the native fishes from the Iberian Peninsula (SW Europe) Open
We reviewed information on Iberian freshwater fish to characterize their migratory status and identify migration reasons and periods. Most species migrate (87.3 %; 62 species from 15 families). A large number are potamodromous species (45 …

LIFE MIGRATOEBRE: Migratory Fish Recovery and Improved Management in the Final Stretch of the Ebre River (Catalonia, NE Iberian Peninsula) Open
The aim of this project is to promote the recovery of ecological connectivity within 10–20 years in the lower Ebre River and Delta, and a healthy and sustainable population of diadromous fish, including European sturgeon (Acipenser sturio)…

Fish Community Size Structure as an Indicator for the Bioassessment of Weir Impact Open
The ecological impacts of large dams on stream fish communities have been largely documented, but there is less research on the impacts of small hydropower plants (hereafter called weirs). Most of the studies that evaluate the impact of we…

Driving Factors of Geosmin Appearance in a Mediterranean River Basin: The Ter River Case Open
In recent decades, human activity coupled with climate change has led to a deterioration in the quality of surface freshwater. This has been related to an increase in the appearance of algal blooms, which can produce organic compounds that…

Development of a Heavy Metal Sensing Boat for Automatic Analysis in Natural Waters Utilizing Anodic Stripping Voltammetry Open
Determination of the levels of heavy metal ions would support assessment of sources and pathways of water pollution. However, traditional spatial assessment by manual sampling and off-site detection in the laboratory is expensive and time-…

Ants as Bioindicators of Riparian Ecological Health in Catalonian Rivers Open
In this study, we assess the potential of ants as bioindicators of riparian ecological health in two river types (upland and lowland type) located in the Catalonian region. We proposed to understand to what extent do metrics based on ant r…
