Responses and adaptation to climate change

Project vision

By delving into the seasonal dynamics of below-ground temperature fluctuations and their correlation with physiological changes in both above- and below-ground components, as well as alterations in rhizosphere biogeochemistry and microbial communities, BORIS aims to uncover the mechanisms safeguarding P. oceanica’s resilience amidst escalating climate threats. Through a multidisciplinary approach spanning ecophysiology, molecular ecology, microbiology, and biogeochemistry, the project seeks to elucidate how the formation of the characteristic ‘matte’ structure of Posidonia oceanica buffers the rhizomes and roots, thus maintaining the seagrass as a potent blue carbon sink in the face of environmental stressors.

(from Pastor et al. 2020)

BORIS specifically aims to assess:

1) how seasonal temperature fluctuations in the below-ground compartment of P. oceanica plants, growing either on ‘matte’ or sediments, track those in the water column;

2) how these fluctuations are associated with changes in physiology and metabolism of above- and below-ground parts of the plant, in the biogeochemistry and microbial communities of the rhizosphere;

3) how marine heatwaves forecasted under future climate scenarios will affect below-ground temperature and how this will impact plant biomass, metabolism and physiology, as well as sediment biogeochemistry and microbial communities.

Project participants

The project is funded by the Italian Ministry of Research PRIN call PNRR 2022 – grant n.P2022R739J. Three Italian research units collaborate towards testing the role of below-ground processes in seagrass meadows facing climate change.
