Ocean Biodiversity

 

Biodiversity hotspots

  •  Areas containing many different species
  •  Important for locating targets for 1
  •  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 2

     –   Had higher temperatures at the 3

     –   Had sufficient 4in the water

Lisa Ballance, 2007

  • Looked for hotspots for marine 5

Census of Marine Life

  •  Found new ocean species living:

     –   Under the 6

     –   Near volcanoes on the ocean floor

Global Marine Species Assessment

  •  Want to list endangered ocean species, considering:

     –   Population size

     –   Geographical distribution

     –   Rate of 7

Aim: to assess 20,000 species and make a distribution 8 for each one

Recommendations to retain ocean biodiversity

  •  Increase the number of ocean reserves
  •  Establish 9 corridors (e.g. for turtles)
  •  Reduce fishing quotas
  •  Catch fish only for the purpose of 10
