• at first only identified on land

 

Boris Worm, 2005

• identified hotspots for large ocean predators, e.g. sharks
• found the ocean hotspots:
  • were not always rich in 32.
  • had higher temperatures at the 33.
  • had sufficient 34. in the water

 

Lisa Ballance, 2007

• looked for hotspots for marine 35.
• found these were all located where ocean currents meet

 

Census of Marine Life

• found new ocean species living:
  • under the 36.
  • near volcanoes on the ocean floor

 

Global Marine Species Assessment

• want to list endangered ocean species, considering:
  • population size
  • geographical distribution
  • rate of 37.

• Aim: to assess 20,000 species and make a distribution 38. for each one

 

Recommendations to retain ocean biodiversity

• increase the number of ocean reserves
• establish 39. corridors (e.g. for turtles)
