Because of recent warming, many areas of kelp forests off the coast of California have become too warm and the kelp have died and not returned. This is an example of what process: O Abiotic environmental change associated with decreased available habitat within the kelp niche. Abiotic environmental change associated with decreased dispersal capacity and reduced habitat accessibility Biotic environmental change associated with decreases in available habitat within the kelp niche O Biotic environmental change associated with decreased dispersal capacity and reduced habitat accessibility.
