Ricklefs, University of Missouri, St. Louis, MO, and approved April 8, 2013 (received for review January 9, 2013) Human exploitation of marine ecosystems is more recent in oceanic (6–8). However, catch statistics can be strongly affected by than near shore regions, yet our understanding of human impacts shifting technologies and markets, and reflect only the abun- on oceanic food webs is comparatively poor. Few records of species dance of species that are harvested.
