Cross-ecosystem subsidies are generally studied with a focus on resource exchange at local ecosystem boundaries. This perspective ignores regional dynamics that can emerge via constraints imposed by the landscape, biotic interactions or the movement of organisms, potentially leading to spatially-dependent effects of subsidies and spatial cascades. In this presentation, I will present experimental evidence that local perturbations can spread across ecosystems and influence the dynamic of entire landscapes. I will conclude with a perspective on future research needs and how this line of research can potentially contribute to scaling-up our understanding of the main drivers of biodiversity and ecosystem function at landscape extent.
