Quando vamos até o fundo do mar, descobrimos que ali jamais poderíamos viver sozinhos.
Então levamos mais alguém.E esta pessoa, chamada de dupla, companheiro ou simplesmente amigo, passa a ser importante para nós.Porque, além de poder salvar nossa vida, passa a compartilhar tudo que vimos e sentimos.E em duplas, passamos a ter equipes, e estas passam a ser cada vez maiores e mais unidas.

E assim entendemos que somos todos velhos amigos mesmo que não nos conheçamos.E esse elo que nos une é maior que todos os outros que já encontramos.E isso faz com que nós mais do que amigos, sejamos irmãos.Faz de nós, mergulhadores.

New map to save coral reefs.

Published this month in online journal PLoS One, a unique map and associated study will help marine park and ecosystem managers to identify coral reefs with the best chance of surviving climate change disturbances.

Marine researchers from Macquarie University, the Wildlife Conservation Society and other groups have compiled a worldwide map including high temperatures, ultra-violet radiation, weather systems, sedimentation, as well as stress-reducing factors such as temperature variability and tidal dynamics.

Lead author, Joseph Maina, is a doctoral student at Macquarie University. "Coral reefs around the globe are under pressure from a variety of factors such as higher temperatures, sedimentation, and human-related activities such as fishing and coastal development," he says. "The key to effectively identifying where conservation efforts are most likely to succeed is finding reefs where high biodiversity and low stress intersect."

The researchers, including Maina and supervisor Joshua Madin, grouped the world's tropical coral reef systems into two clusters, based on the sum of their stress exposure grades and factors that reinforce and reduce these stresses.

The first cluster looked at coral regions in South East Asia, Micronesia, the Eastern Pacific, and the central Indian Ocean, characterised by high radiation stress, with few stress-reducing factors.

The second cluster looked at the Caribbean, Great Barrier Reef, Central Pacific, Polynesia, and the Western Indian Ocean, regions characterised by moderate to high rates of radiation exposure but also with high rates of reducing factors.

Overall, stress factors such as surface temperature, ultra-violet radiation, and doldrums were the most significant factor for reinforcing and reducing ecosystem stress, and one that ecosystem management has no control over. What is controllable, however, is the mitigation of human impacts that reinforce radiation stress and where managers decide to locate their protected areas.

The authors recommend that the study results can be used to formulate management strategies that would include activities such as fishing restrictions, and the management of watersheds through improved agricultural practices and reforestation of coastal watersheds that play a role in health coral systems.

The authors include: Joseph M. Maina of Macquarie University, Timothy R. McClanahan of the Wildlife Conservation Society; Valentijn Venus of Netherlands Institute for Geo-Information Science and Earth Observation; Mebrahtu Ateweberhan of the University of Warwick; and Joshua Madin of Macquarie University, Sydney, Australia.
