Ocean Biodiwersity

Biodiversity hotspots

• areas containing many different species

• important for locating targets for 【C1】 .............................

• 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 【C2】 ............................

- had higher temperatures at the 【C3】 .............................

- had sufficient 【C4】 .............................in the water

Lisa Ballance, 2007

• looked for hotspots for marine 【C5】 .............................

• found these were all located where ocean currents meet

Census of Marine Life

• found new ocean species living:

- under the 【C6】 .............................

- near volcanoes on the ocean floor

Global Marine Species Assessment

• want to list endangered ocean species, considering:

- population size

- geographical distribution

- rate of 【C7】 .............................

• Aim: to assess 20,000 species and make a distribution 【C8】.............................for each one

Recommendations to retain ocean biodiversity

• increase the number of ocean reserves

• establish 【C9】 ............................ corridors (e.g. for turtles)

• reduce fishing quotas

• catch fish only for the purpose of 【C10】 .............................
