The Parties to the Convention on Migratory Species of Wild Animals (CMS) just agreed to list giant mantas on Appendix 1 and II of CMS at their tri-annual meeting in … Read More “Giant manta rays protected by Convention on Migratory Species” »

Science

Two pieces of good news for European sharks were announced yesterday. The European Union signed the UN Convention on Migratory Species (CMS) Memorandum of Understanding for sharks. This MOU was established last year to support the conservation of seven shark species which regularly migrate between national boundaries, a list which includes great whites and whale sharks. … Read More “European Union officials propose stronger finning ban, sign UN migratory shark initiative” »

Vote for me in the blogging scholarship and support our shark conservation research!

Yesterday, I asked for your support and vote in the 2011 Blogging Scholarship. Since that time, over 7,000 of you have voted for me, and as of this writing, I am in the lead! Thanks for your help and encouragement. Andrew announced earlier today that for every day I’m in the lead, he’ll post an embarrassing picture of me. For many of you, that’s incentive enough to vote for me. However, I also want to tell you what I would use the $10,000 scholarship for if I won.

In addition to boring stuff like tuition, supplies, and travel support, for my own dissertation (assessing the ecological importance of sharks to coral reefs) , I will use the money to support our lab’s ongoing shark conservation research. My lab, the RJ Dunlap Marine Conservation Program at the University of Miami, has many shark research projects taking place. Yesterday, some of that research was used by the Florida Fish and Wildlife Conservation Commission as background in their decision to make hammerheads (great, smooth, and scalloped) and tiger sharks protected species in Florida waters- a proud moment for us and for the Abess Center for Ecosystem Science and Policy, which we are affiliated with.

A few weeks ago, I wrote about a proposed shark cull in Western Australia and asked for your help to oppose it. By the end of the Support Our Sharks anti-cull campaign, the petition had almost 19,000 signatures from dedicated shark conservationists from around the world, including many of our readers. After some initial anti-shark … Read More “Cull canceled: victory for the sharks of Western Australia!” »

Threatened gentle giants: both species of manta ray added to the IUCN Red List

Conservation, Science

Manta rays are true gentle giants; though they can grow more than 20 feet wide from wingtip to wingtip, they eat only plankton. Swimming with these animals is a rare thrill for SCUBA divers, and manta-viewing ecotourism is worth over $100 million each year. Like many species of sharks, manta rays grow slowly and reproduce … Read More “Threatened gentle giants: both species of manta ray added to the IUCN Red List” »

Traveling the world in 140 characters or less: How Twitter got me a trip to New Zealand

November 7, 2011December 9, 2011 David Shiffman 1 Comment

Last May, I attended the 2nd International Marine Conservation Congresss, an interdisciplinary conference that brought together scientists, NGOs, policymakers, and interested members of the general public. It was the largest professional meeting dedicated to saving the oceans in history, and it was an honor to be a part of it. In addition to seeing old friends and meeting some of my heroes, I took the opportunity to “live-Tweet” the talks I attended. Whenever a presenter made an important point, I summarized it in a Tweet, and, whenever possible, I included relevant hashtags (#Shark, #bycatch) and links to more information (either a website or published paper affiliated with the presenter, or one from a 3rd party working in the same field).

Support “Shored Up”, a new documentary about beach renourishment

November 6, 2011December 9, 2011 David Shiffman 2 Comments

Conservation

Our friends from the fantastic ocean acidification documentary A Sea Change are working on an important new project. It’s called “Shored Up“, and it’s all about sea level rise and the strategies that coastal communities are using to try and keep their beaches.

One issue in particular, beach renourishment, has major environmental implications that aren’t often considered. Sand provides critical habitat for organisms other than tourists, and not all sand is the same: it differs in grain size, chemical composition, and other variables. Organisms that are adapted to one type of sand, such as beach-dwelling crabs and snails, often struggle to survive in another that’s dumped in huge quantities in their habitat. Additionally, the ecosystem where the sand comes from is often greatly disturbed by the huge sand-collecting dredges.

The movie doesn’t just focus on renourishment, however:
