University of Sao Paulo re search project three crucial reef busilding corals

Shift in distribution and habitat loss of stoney coral reefs

Stoney Corals

Climate change - life under water

Loss of coral reefs Jeopardize millions of people.

3. Nutrient Cycling

2. Coastal Protection

1. Food Provision

Coral reef offer vital ecosystem services

a.If coral reefs are lost the provision of their services would be consequential and threatning. b.Human activities has harmed coral reef structure. c. Climate change is also a adding problem.

Coral reefs have to build deposit calcium carbonate

Mass bleaching. Ocean acidification. Pollution. Urbanization. Fisheries. Tourism.

Causes of loss of coral reefs.

Unprecedented cascading impacts on entire : marine life. Community. Structural complexity of reef ecosystem.

Climate change - impacts.

1.Optimistic 2.Pessimistic 3.Moderate

Future changes in the range under 3 different climate scenarios.

All these areas will experience decrease in stoney corals.

All 3 will experience changes in distribution.

Western atlantic.Lose habitat suitabilityBrazilian coast. The caribbean.

Most optimistic.

Certain areas region in the coast of Brazil will completely lose atlest one species.

Researchers should focus on refuge area that might contribute to being the safe area for these species in future. (Principe)Government Backed Emission policy Minimise Residential and Industrial structures near oceans.
