Sensitivity of a cold‐water coral reef to interannual variability in regional oceanography
Abstract Aim We assessed the effects of regional oceanographic shifts on the macrofaunal biodiversity and biogeography of cold‐water coral reefs (CWCRs). CWCRs are often hotspots of biodiversity and ecosystem services and are in the frontline of exposure to multiple human pressures and climate chang...
