We conducted a 'classic' kelp canopy removal exp in mixed Laminaria forests in southwest UK. Results show that loss of canopy increases 5-fold the light reaching the reef which leads to 7-fold increase in understorey algae & 9-fold increase in kelp recruits; ms: www.sciencedirect.com/science/arti...
