ASTANA – From coral reefs and the microscopic organisms that sustain them to marine mammals inhabiting the Caspian Sea, every species is part of a larger natural system. A photo exhibition that explores this interconnected world opened in Astana on Sept. 23, bringing together stories of biodiversity from Kazakhstan and around the world.

One biodiversity story comes from a small laboratory in London, where marine biologist Jamie Craggs, a co-founder of Coral Spawning International, managed to recreate the natural conditions required for coral spawning.
The work has opened new possibilities for producing young corals in controlled conditions while maintaining greater genetic diversity.

Unlike traditional coral gardening methods, the project uses sexual reproduction to produce genetically diverse corals. Early results recorded the settlement and growth of around 65,000 young corals. As Maral Rakhimzhanova, corporate communications manager at Canon’s representative office in Kazakhstan, explained, the importance of coral reefs extends far beyond their colourful appearance.
“Corals are very colorful, but in fact their color is given by algae that live in symbiosis with them. It is a relationship between two living organisms,” she said.

If the stress continues, the corals may eventually die. Reefs also provide food and shelter for a wide range of marine species, linking corals to the wider food chain. Rakhimzhanova noted that these connections are relevant for a landlocked country such as Kazakhstan, as changes in one part of the natural world can have consequences far beyond it.
