Humans have drastically altered the abundance of animals in marine ecosystems. Reduced abundance destabilize food webs, leading to cascading effects that dramatically reorganize community structure. However, additional implications of these top-down changes for biogeochemical cycles via consumer-mediated nutrient dynamics are often overlooked, particularly for coastal areas. Here, scientists review research that underscores the importance of this bottom-up control at local, regional, and global scales in coastal marine ecosystems. [Source: Global Change Biology]
