Contract researcher or PhD student, profile yet to be defined

• River vegetation types and distribution patterns: woody and herbaceous
• Vegetation benchmarks for quality assessment and restoration
• Assessment of ecological integrity using multivariate and multimetric tools

• Invasive plants in river corridors and their profiles of biological attributes
• Invasiveness in reference and non-reference sites
• Environmental drivers of invasion

• Response of riparian vegetation to regulation
• Response of riparian vegetation to channelisation

• Wetland wood types along all the western Iberian Atlantic coast
• Structural characteristics within stands
• Multi-scale environmental factors determining vegetation and structure

• Influence of different types of land use on riparian woods
• Human-related influence close to the river corridor vs. in the river valley
• Changes in riparian integrity in 75 years in relation to changes of land use

• Relative influence of riparian and environmental variables on stream functioning
• Organic matter processing
• Tree foliar isotope signatures
