Climate change - life under water

Stoney Corals

Shift in distribution and habitat loss of stoney coral reefs

Masmussismilia Hispida Montastrea carvernosa Siderastrea complex

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

Coral reef offer vital ecosystem services

1. Food Provision

2. Coastal Protection

3. Nutrient Cycling

Loss of coral reefs Jeopardize millions of people.

Coral reefs have to build deposit calcium carbonate

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.

Causes of loss of coral reefs.

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

Climate change - impacts.

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

Future changes in the range under 3 different climate scenarios.

1.Optimistic 2.Pessimistic 3.Moderate

Most optimistic.

All 3 will experience changes in distribution.

All these areas will experience decrease in stoney corals.

Western atlantic.Lose habitat suitabilityBrazilian coast. The caribbean.

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.
