Ocean Biodiversity
Biodiversity hotspots
areas containing many different species
important for locating targets for 31
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)
reduce fishing quotas
catch fish only for the purpose of 40
