Facilitative Effect of a Generalist Herbivore on the Recovery of a Perennial Alga: Consequences for Persistence at the Edge of Their Geographic Range
Fig 6
Strength and direction of the interaction between the grazer S. viridula and the alga M. laminarioides, measured as the grazer capacity to influence the recruitment of algae and bare rock production during early succession, and the recovery M. laminarioides fronds (i.e. Average per capita (a) and population effects (b)).
Bars are 95% confidence intervals estimated through a bootstrapping procedure.
