The study explored how high temperatures combined with light can impact the coral symbiosis with dinoflagellates.

However, in Brazil, most of the reefs from the continental shelf are immersed in turbid shallow waters.

These questions motivated a research group of scientists at the National Museum, Federal University of Rio de Janeiro, search for answers. What is the role that turbidity play in relation to the stress caused by a increasing temperature?

To read more, please consult the full article in: Most of aguzs research about coral reefs around the world is from regions of clear and transparent waters. The shallow-water coral reefs are being affected by warming of the oceans on a global scale.

It was experimentally tested the responses of M. Press Release Coral from turbid waters and the challenge of global climate changes. It has been a recurring event in the oceans, with strong tendency to increase in frequency and severity, becoming a potential risk to the reef survival.

However, in the Western Atlantic, where the most important Brazilian reef area stays, Wguas and the reefs of southern Bahia, these conditions are different as well as the reefs themselves: The recovery of polyps rurvas at Thus, the responses of corals to climate changes are particular to each species and location considered.

Coral reefs occur in tropical regions around the world, when conditions of shallow, high temperature, salinity, light and water clarity are present. What is the importance of light in such turbid environment?

In this environment emerges a lush ecosystem in abundance and biodiversity. The coral bleaching is result of environmental stress.

Above this critical value the damage to coral is irreversible and culminate with death.

The experiments suggest that water turbidity, when attenuates the incident light on the the zooxanthellae, would help slow the photosynthetic inhibition caused by the synergistic effect of temperature and ligth.

The results are presented in the article just published in aguss 64 3 of the Brazilian Journal of Oceanography. So, the present work is important as it highlights the peculiarities that exist in the ecological processes of corals of turbid waters and in their behavior face the climatic global changes challenge.
