Citizen science surveys compare well with traditional scientific methods when it comes to monitoring species biodiversity -- according to new research from the University of East Anglia.
Research published today in the journal Methods in Ecology and Evolution shows that methods to record marine diversity used by amateurs returned results consistent with techniques favoured by peer-reviewed science.

Shark fin soup is a delicacy in Asia. But its popularity is helping to decimate shark populations. However, governments voted Monday (today) to protect five species of the predators. Preliminary approval came at a U.N. meeting on wildlife trade in Bangkok, Thailand.

Conservationists look to final plenary to cement positive yet tentative decisions
Bangkok, 11 March 2013. In a highly anticipated Committee vote today, proposals to list under CITES* five species of sharks were supported by more than the two-thirds majority of voting countries needed for adoption. Conservationists are pleased yet mindful that decisions must still be confirmed in the final plenary session later this week.

Thailand signals opposition to CITES listings while Senegal proclaims support
Debate is heating up on proposed protections for sharks and rays at a major global trade meeting. Shark conservation experts have united to urge governments to vote in favour of the measures and thereby ensure the survival of the threatened species. Roughly 150 of the 178 governments that are party to the Convention on International Trade in Endangered Species (CITES) are expected to vote on these proposals over the coming days.

Increased trade protection for polar bears and sharks are on the agenda of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) next week in Bangkok, officials said Thursday.
"We expect proposals on polar bears, sharks and manta rays will go to a vote," convention secretary general John Scanlon said.
The CITES meeting, which is to begin Sunday and run through to March 14, is drawing more than 2,000 delegates from 177 countries.

Overfishing threatens the magnificent and prized ‘Ali Maduwa’, writes Malaka Rodrigo.
A giant “maduwa”, or manta ray, was netted last week by fisherman in Welipatanwila, Ambalanthota, on the South coast. The ocean creature was pregnant and weighed 1,500 kilograms. A week earlier, another manta ray was caught by fishermen in Akkaraipattu, on the East coast. Both sea creatures have been identified as Giant Oceanic Manta Rays, the largest member of the ray family.

Some sharks spend extended time periods in the protected waters of the Bahamas yet roam long distances when they leave
As the nations of the world prepare to vote on measures to restrict international trade in endangered sharks in early March, a team of researchers has found that one of these species – the oceanic whitetip shark – regularly crosses international boundaries. Efforts by individual nations to protect this declining apex predator within their own maritime borders may therefore need to be nested within broader international conservation measures.
