Ocean Biodiversity

Biodiversity hotspots

• areas containing many different species
• important for locatiing targets for 31  
• at first only identified on land

Boris Worm, 2005

• ​​​​​​identified hotspots for large ocean predators, e.g. sharks
• ​​​​​​found that 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)
• • reduce fishing quotas
• • catch fish only for the purpose of 40 ​
