Aim: Empirically disentangle the effects of global change drivers on biodiversity and ecosystem multifunctionality across the river Thur catchment using existing eDNA and remote sensing data.
Research: We integrate core expertise of the URPP in which we are world-leading namely remote sensing and genomic tools, to assess biodiversity and cross disciplinary boundaries. We will contribute innovation to the development of Essential Biodiversity Variables, providing scalable and unifying biodiversity measures, covering microbes to land-use metrics, expecting high-profile output. We unify scalable (space and time), empirically-based predictors of biodiversity change to assess the scale at which biodiversity-states (microbial richness) are linked to biodiversity-processes (productivity).
