Synergistic effects of climate change and local stressors: CO 2 and nutrient‐driven change in subtidal rocky habitats
Abstract Climate‐driven change represents the cumulative effect of global through local‐scale conditions, and understanding their manifestation at local scales can empower local management. Change in the dominance of habitats is often the product of local nutrient pollution that occurs at relatively...
