Linear and non-linear responses of vegetation and soils to glacial-interglacial climate change in a Mediterranean refuge

Abstract The impact of past global climate change on local terrestrial ecosystems and their vegetation and soil organic matter (OM) pools is often non-linear and poorly constrained. To address this, we investigated the response of a temperate habitat influenced by global climate change in a key glac...
