Richness of experimental marine invertebrate communities across latitude (Competition and Predation across Latitude)

Richness of sessile marine invertebrate communities from coastal sites across a latitudinal gradient spanning the subarctic to the tropics. Communities developed for three or 12 months under nine different treatments that tested the effect of predation and competition. Caging was used to reduce predation pressure and biomass removals opened up space, a limiting resource in sessile communities.
