Screening Alnus glutinosa resistance to an emerging disease under climatic stressors: predicting alder forest resilience across river networks.

Evaluating the current status of alder decline in the leading-edge of Phytophthora spread in Portugal

Characterizing alder variability across provenances along the species latitudinal range

Investigating variability in the resilience of populations

Proposing a novel decision support tool for planning riparian conservation guidelines

Alder forests in Europe play key ecological functions and provide important ecosystem services in riparian habitats (e.g. water quality improvement, nitrogen fixation). However, they are experiencing extensive decay and tree mortality, which add new risks to the existing impacts of historical pressures related to river and riparian forest degradation. The pathogen Phytophtora xalni is an emerging threat that affects alder forests from Northern and Central Europe and is now spreading across the Iberian Peninsula. The persistence of the forests affected by this disease may be also affected by other threats such as climate change, which can lead to a higher stress for the species with cascading effects to the ecosystem functioning and services.
