WWF: Marine reserves could offset climate change costs

Future Seas is based on two scenarios developed by a representative group of fishers, scientists, energy experts, community leaders, eco-tour operators, environmentalists, and Mäori and government representatives

The report examines the long-term future of New Zealand’s marine environment, which faces tremendous outside pressure on its resources, including from fishing and mineral extraction, competing interests within the marine environment, and pollution of marine habitats

The Common Octopus, Octopus vulgaris.

All cephalopods are venomous

A broad study of cephalopods - more commonly known as octopuses, cuttlefish and squid - has shown that they all possessed toxic proteins that performed functions such as paralysing the nervous system of prey.

The scientists analysed tissue samples from cephalopods from Hong Kong, the Coral Sea, the Great Barrier Reef and Antarctica.

The different species' genes were then studied for venom protection and it was found that a venomous ancestor produced one set of venom proteins, but over time additional proteins had added to the chemical arsenal.

Deep-sea coral found to be over 4000 years old

A black deepsea coral found about 400 meters from Oahu and the Big Island in Hawaii is more than 4,000 years old — making it the oldest marine organism ever found, according to researchers from Lawrence Livermore National Laboratory, Stanford University and the University of California, Santa Cruz.

Using a manned deep-sea research submersible samples were collected at the Makapuu and Lanikai deep-sea coral beds off the coast of Oahu, Keahole Point deep-sea coral bed off the coast of the Big Island and Cross Seamount about 100 miles south of Oahu.

On the origin of the great white shark

A new 4-million-year-old fossil from Peru described in this month’s issue of the Journal of Vertebrate Paleontology provides important evidence suggesting the shark’s origins may be more humble than previously believed.

Shark fossils very rare

Dana Ehret, Gordon Hubbell and Bruce MacFadden studied an exceptionally well-preserved fossil of a species of white shark (Carcharodon sp.) from Peru (estimated to be about 5 m long by the authors), consisting of a complete jaw with 222 teeth, and 45 vertebrae, in their paper.

Yellow band disease is spreading

This affliction etches a swath of pale-yellow or white lesions along the surface of an infected coral colony. The discoloured band is a mark of death, indicating where the bacterial infection has killed the coral’s photosynthetic symbionts, called zooxanthellae. The coral host suffers from cellular damage and starves without its major energy source, and usually does not recover.

New US Entry Procedures Take Effect

The Department of Homeland Security is introducing the new system to replace the current Visa Waiver Program (VWP). All countries currently eligible to use the VWP will be legally required to obtain authorization before their departure.

Applications are free of charge and are processed in about four seconds. Approximately 14,000 people are currently registering with ESTA daily with an approval rating of 99.6%. Travelers should be aware that a number of websites that are not endorsed by the US government are charging a fee for ESTA information or application processing.

Ana the Green Turtle swims from Indonesia to Australia

Her journey across the Indian Ocean from a nesting beach in East Java to Kimberley in Western Australia demonstrates the strong biological ties between Indonesia and the reefs on the west Australian coast.

“Ana’s journey has revealed an ‘oceanic superhighway’ that helps us better understand how marine turtles navigate around the world’s oceans as well as highlighting the strong ecological and evolutionary connections between Indonesia and Australia’s Kimberley-Pilbara coast,” said Gilly Llewellyn, WWF Ocean’s Program Leader.

Do whales like jazz?

Interspecies was started in 1978, to grant artists the same access to wilderness and wild animals that is usually reserved for field biologists. Their goal and belief is that science is not the only approach to understanding nature. During the 1980s, Interspecies sponsored over 100 musicians to attempt communication with orcas off western Canada.
