  1. Changing Oceans:A Census-NCEAS collaboration Boris Worm Ray Hilborn Heike Lotze Andy Rosenberg Jeremy Collie Simon Jennings And others

  2. Major drivers in the anthopocene Fishing Warming Eutrophication Modified after Pauly & MacLean 2003, Island Press

  3. The anthropocene biosphere • From large to small • From low to high population growth • From vertebrate to invertebrate • From benthic to pelagic • From rare, specialized to common, cosmopolitan • From cold- to warm adapted

  4. Size-based models
