International group sanctions restrictions on trade of endangered species
By Summit Voice
FRISCO — Years of efforts by ocean conservation advocates yielded results last week, as the Convention on International Trade in Endangered Species adopted new protections for five species of highly traded sharks, as well as two species of manta rays and one species of sawfish.
Japan, Gambia and India unsuccessfully challenged the Committee decision to list the oceanic whitetip shark, while Grenada and China failed in an attempt to reopen debate on listing three hammerhead species. Colombia, Senegal, Mexico and others took the floor to defend Committee decisions to list sharks. Continue reading

Parts of Patagonia‘s spectacular coastline will have more protection following the designation of two new marine preserves.
Isla Pingüino and Makenke Coastal Marine Park provide habitat for seabirds and marine mammals
By Summit Voice
FRISCO — Dolphins, penguins, seabirds and sea lions along the coast of Patagonia will get more protection in a pair of new marine protected areas designated by Argentina this week.
Both areas were identified as priority conservation sites under the collaborative Patagonia Coastal Zone Management Plan project, covering an area where Charles Darwin traveled, and where Ferdinand Magellan executed and marooned a group of mutineers intent on aborting what would become the world’s first circumnavigation of the globe.
Darwin first described the wildlife of Isla Pingüino in 1833, during his seminal voyage aboard the HMS Beagle — now, the Isla Pingüino Coastal Marine Park will protect about 720 square miles, including habitat for large populations of South American sea lions, red-legged cormorants, and one of the largest colonies of imperial cormorants found anywhere (with more than 8,000 breeding pairs). Isla Pingüino also boasts one of the only colonies of rockhopper penguins on the coast of Patagonia. Continue reading

Simplified assessment could help resource managers decide where to focus efforts
By Summit Voice
SUMMIT COUNTY — Global warming has spurred dire warnings about the future of coral reef ecosystems, with warnings that many reefs could be wiped out by bleaching, sending biologists scrambling to develop conservation strategies.
A sometimes bewildering array of coral reef environments makes the task daunting, but a new study may illustrate a way to streamline coral reef conservation decisions.
Heat-tolerant species living in areas with continuous background temperature variability have the best chance of surviving climate change, according new studies by the Wildlife Conservation Society and other researchers. These corals should be the focus of conservation efforts, the study concludes. Continue reading

Local communities on the front line in marine protection
By Summit Voice
SUMMIT COUNTY — Local grassroots efforts to protect marine habitat are paying off in Fiji, which is making progress toward the goal of protecting at least 30 percent of Fiji’s inshore habitats.
A new study by researchers from the Global Change Institute at the University of Queensland, the ARC Centre of Excellence for Coral Reef Studies at James Cook University, and the Wildlife Conservation Society outlined some of the successes — along with some of the remaining challenges.
“The results of the study are remarkable given that locally managed marine area networks in Fiji and the Western Pacific region are generally established only to meet local objectives, most notably to improve food security,” said Dr. Morena Mills, lead author of the paper. Continue reading

New study to help inform conservation policy
By Summit Voice
SUMMIT COUNTY — While images of manta rays are ubiquitous on brochures and websites for popular seaside tourist destinations, very little is known about where the ocean giants live and what they need to survive.
But that’s starting to change, thanks to an international study that used satellite tracking technology to study manta rays off the coast of Mexico’s Yucatan Peninsula over a 13-day period. The tracking devices were attached to the backs of six individuals —four females, one male, and one juvenile.
“The satellite tag data revealed that some of the rays traveled more than 1,100 kilometers during the study period,” said Dr. Matthew Witt of the University of Exeter’s Environment and Sustainability Institute. “The rays spent most of their time traversing coastal areas plentiful in zooplankton and fish eggs from spawning events.” Continue reading

Impacts to marine mammals a big concern with more traffic in Bering Strait
By Summit Voice
SUMMIT COUNTY — Conservation experts and indigenous people in the far north urged caution as trans-Arctic shipping increases in the formerly ice-choked waters of the Arctic ocean.
The rapid increase in commercial ship traffic poses a significant risk to the region’s marine mammals and the local communities that rely on them for food security and cultural identity, according to Alaska Native groups and the Wildlife Conservation Society, who convened at a recent workshop.
“The disappearance of summer sea ice from the region’s coastal areas is leading to major changes in this part of the world,” said Dr. Martin Robards, Director of the World Conservation Society’s Beringia Program and one of the event’s organizers. Continue reading

Study sheds light on Indian Ocean humpback whales

By Summit Voice
SUMMIT COUNTY —Humpback whales on opposite sides of the Indian Ocean are singing different songs, a team of marine biologists say, explaining that that their findings are unusual because humpbacks in the same ocean usually all sing very similar tunes.
The differences in song between the Indian Ocean humpback populations most likely indicate a limited exchange between the two regions and may shed new light on how whale culture spreads. Continue reading

Conservation biologists hope to rebuild regional population
By Summit Voice
SUMMIT COUNTY —In an age when global biodiversity is collapsing at an astounding rate, it’s good to celebrate small conservation victories, like last week’s release of a rare southern river terrapin to the Sre Ambel River in Cambodia.
Working with government agencies in the region, the Wildlife Conservation Society last week said biologists released one of the most endangered turtles on earth into the wild in an area where the reptiles may be able to re-establish a stronghold.
The female turtle weighs about 75 pounds and has been equipped with a satellite transmitter that will allow conservationists to track its whereabouts – the first-ever satellite monitoring study for this species. Continue reading

SUMMIT COUNTY — Fishing closures in protected marine areas around the spectacular Mesoamerican reef near Belize have helped recover populations of barracuda, groupers, snappers, and other predatory fish, but herbivorous fish that clean algae from the coral are not faring as well.
Results of a long-term study by the Wildlife Conservation Society show that parrotfish an surgeonfish in the Glover’s Reef study area make only sight recoveries — not enough to reverse the degradation by caused by algae overgrowing the reefs and replacing the coral that once covered 75 percent, but now represent less than 20 percent, of the seafloor cover.

Wildlife group tracks pinniped as part of Patagonia study

SUMMIT COUNTY — A southern elephant seal nick-named Jackson astonished researchers when it swam more than 18,000 miles during the past year, about equal to a round trip from New York to Sydney and back again.
The Wildlife Conservation Society tracked the giant pinniped through the rugged fjords of Patagonia as a part of a research project for a new model of private-public, terrestrial-marine conservation of the Admiralty Sound, Karukinka Natural Park (a WCS private protected area), and Alberto de Agostini National Park. It will help build a broader vision for bolstering conservation efforts across the Patagonian Sea and coast.
“Jackson’s travels provide a roadmap of how elephant seals use the Patagonian Coast and its associated seas,” said Caleb McClennen, Wildlife Conservation Society director for global marine programs. “This information is vital to improving ocean management in the region, helping establish protected areas in the right places, and ensuring fisheries are managed sustainably without harming vulnerable marine species like the southern elephant seal.” Continue reading
