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]]
