Threats to large brown algal forests in temperate seas: the overlooked role of native herbivorous fish

Abstract Canopy-forming algae are declining globally due to multiple disturbances. This decline has recently been on the increase due to the spread of some tropical herbivorous fishes. This new phenomenon has drawn attention to the effects of fish herbivory in temperate areas, which have been assume...
