Kelp Forests versus Urchin Barrens: Alternate Stable States and Their Effect on Sea Otter Prey Quality in the Aleutian Islands
Figure 6
MDS bubble plot of the contribution of sea otter prey biomass to the separation in kelp forest and urchin barren communities in the central and western Aleutian Islands, Alaska. Bubble size scales with g·0.25 m−2 from remnant kelp forest (klp) and urchin barren (brn) sites.
