What is the role that turbidity play in relation to the stress caused by a increasing temperature?

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

It was experimentally tested the responses of M. In this environment emerges a lush ecosystem in abundance and biodiversity. 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 agias changes challenge. Most of the research about coral reefs around the world is from regions of clear and transparent waters.


Photo from Winter et al. 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. The recovery of polyps maintained at Thus, the responses of corals to climate changes are particular to each aguax and location considered. Press Release Coral from turbid waters and the challenge of global climate changes.

What is the importance of light in such turbid environment? To read more, please turvzs the full article in: Above this critical value the damage to coral is irreversible and culminate with death. The coral bleaching is result of environmental stress. However, in Brazil, most of the reefs from the continental shelf are immersed in turbid shallow waters.


However, in the Western Atlantic, where the most important Brazilian reef area stays, Abrolhos and the reefs of southern Bahia, these conditions are different as well as the reefs themselves: Coral reefs occur in tropical regions around the world, when conditions of shallow, high temperature, salinity, light and water clarity are present.

The results are presented in the article just published in volume 64 3 of the Brazilian Journal of Oceanography. The shallow-water coral reefs are being affected by warming of the oceans on a global scale.

These questions motivated a research group of scientists at the National Museum, Federal University of Rio de Janeiro, search for answers.
