Aigüestortes i Estany de Sant Maurici
  • Alpine ecosystems have high ecological value and biodiversity, and provide important ecosystem services, but are highly vulnerable to climate and land use changes.
  • Despite their ecological importance and vulnerability, there is a lack of information on soil biodiversity, exchange of greenhouse gases (GHG) and carbon (C) and nitrogen (N) dynamics of alpine meadows.
  • Variations in soil plant and microbial communities, combined with environmental changes, can affect climate regulation by altering GHG exchanges and C and N cycling.

The creation of the IBERALP network is proposed to study the vulnerability to climate change of biodiversity and the exchange of GHG in the alpine communities of five Iberian mountain National Parks (PN): Picos de Europa, Ordesa y Monte Perdido, Aigüestortes i Estany de Sant Maurici, Sierra de Guadarrama, Sierra Nevada.

Ordesa y Monte Perdido


The main objective is the analysis of interactions between components of biodiversity, mainly plant and soil microbial diversity, and their relationship with GHG flows; and how these interactions are affected by climate change.
