World coming up short on promised marine sanctuaries

Observer4 days ago

Brest: A global target of having 30 per cent of the oceans become protected areas by 2030 is looking more fragile than ever, with little progress and the United States backing away, conservationists say.
"With less than 10 per cent of the ocean designated as MPAs (marine protected areas) and only 2.7 per cent fully or highly protected, it is going to be difficult to reach the 30 per cent target," said Lance Morgan, head of the Marine Conservation Institute in Seattle, Washington.
The institute maps the MPAs for an online atlas, updating moves to meet the 30 per cent goal that 196 countries signed onto in 2022, under the Kunling-Montreal Global Biodiversity Framework.
The ambition is notably at risk because "we see countries like the US reversing course and abandoning decades of bipartisan efforts" to protect areas of the Pacific Ocean, Morgan said.
That referred to an April executive order by President Donald Trump authorising industrial-scale fishing in big swathes of an MPA in that ocean.
Currently, there are 16,516 declared MPAs in the world, covering just 8.4 per cent of the oceans.
But not all are created equal: some forbid all forms of fishing, while others place no roles, or almost none, on what activities are proscribed or permitted.
"Only a third of them have levels of protection that would yield proper benefits" for fish, said Joachim Claudet, a socio-ecology marine researcher at France's CNRS.
Daniel Pauly, a professor of fisheries science at Canada's University of British Columbia, said "The marine protected areas have not really been proposed for the protection of biodiversity" but "to increase fish catches".
A proper MPA "exports fish to non-protected zones, and that should be the main reason that we create marine protected areas — they are needed to have fish", he said.
When fish populations are left to reproduce and grow in protected areas, there is often a spillover effect that sees fish stocks outside the zones also rise, as several scientific journals have noted, especially around a no-fishing MPA in Hawaiian waters that is the biggest in the world.
One 2022 study in the Science journal showed a 54 per cent increase in yellowfin tuna around that Hawaiian MPA, an area now threatened by Trump's executive order, Pauly said.
For such sanctuaries to work, there need to be fishing bans overall or at least some of their zones, Claudet said. But MPAs with such restrictions account for just 2.7 per cent of the ocean's area and are almost always in parts that are far from areas heavily impacted by human activities.
In Europe, for instance, "90 per cent of the marine protected areas are still exposed to bottom trawling," a spokesperson for the NGO Oceana, Alexandra Cousteau, said. "It's ecological nonsense." Pauly said that "bottom trawling in MPAs is like picking flowers with a bulldozer... they scrape the seabed".
Oceana said French MPAs suffered intensive bottom trawling, 17,000 hours' worth in 2024, as did those in British waters, with 20,600 hours. The NGO is calling for a ban on the technique, which involves towing a heavy net along the sea floor, churning it up.
A recent WWF report said that just two per cent of European Union waters were covered by MPAs with management plans, even some with no protection measures included.
The head of WWF's European office for the oceans, Jacob Armstrong, said that was insufficient to protect oceanic health.
Governments need to back words with action, he said, or else these areas would be no more than symbolic markings on a map. — AFP

Chicago museum's fossil yields insights on famed early bird Archaeopteryx

A new analysis of a pigeon-sized Archaeopteryx fossil in the collection of the Field Museum in Chicago is revealing an array of previously unknown features of the earliest-known bird, providing insight into its feathers, hands, feet and head. The specimen, unearthed in southern Germany, is one of the most complete and best preserved of the 14 known fossils of Archaeopteryx identified since 1861. The discovery of the first Archaeopteryx fossil, with its blend of reptile-like and bird-like features, caused a sensation, lending support to British naturalist Charles Darwin's ideas about evolution and showing that birds had descended from dinosaurs. The new study, examining the Chicago fossil using UV light to make out soft tissues and CT scans to discern minute details still embedded in the rock, shows that 164 years later there is more to learn about this celebrated creature that took flight 150 million years ago during the Jurassic Period. The researchers identified anatomical traits indicating that while Archaeopteryx was capable of flight, it probably spent a lot of time on the ground and may have been able to climb trees. The scientists identified for the first time in an Archaeopteryx fossil the presence of specialized feathers called tertials on both wings. These innermost flight feathers of the wing are attached to the elongated humerus bone in the upper arm. Birds evolved from small feathered dinosaurs, which lacked tertials. The discovery of them in Archaeopteryx, according to the researchers, suggests that tertials, present in many birds today, evolved specifically for flight. Feathered dinosaurs lacking tertials would have had a gap between the feathered surface of their upper arms and the body. "To generate lift, the aerodynamic surface must be continuous with the body. So in order for flight using feathered wings to evolve, dinosaurs had to fill this gap - as we see in Archaeopteryx," said Field Museum paleontologist Jingmai O'Connor, lead author of the study published on Wednesday in the journal Nature. "Although we have studied Archaeopteryx for over 160 years, so much basic information is still controversial. Is it a bird? Could it fly? The presence of tertials supports the interpretation that the answer to both these questions is 'yes,'" O'Connor added. The delicate specimen, preserved in three dimensions rather than squashed flat like many fossils, was painstakingly prepared to protect soft tissue remains, which glowed under ultraviolet light. Birds are the only members of the dinosaur lineage to have survived a mass extinction 66 million years ago, caused by an asteroid striking Earth. Archaeopteryx boasted reptilian traits like teeth, a long and bony tail, and claws on its hands, alongside bird-like traits like wings formed by large, asymmetrical feathers. The soft tissue of its toe pads appears to have been adapted for spending a lot of its life on the ground, consistent with the limited flight capabilities that Archaeopteryx is believed to have possessed. "That's not to say it couldn't perch. It could do so still pretty well. But the point being that near the beginning of powered flight, Archaeopteryx was still spending most of its time on the ground," said study co-author Alex Clark, a doctoral student in evolutionary biology at the University of Chicago and the Field Museum. The soft tissue on the hand suggests that the first and third fingers were mobile and could be used for climbing. An examination of Archaeopteryx's palate - roof of the mouth - confirmed that its skull was immobile, unlike many living birds. But there was skeletal evidence of the first stages in the evolution of a trait that lets the beak move independently from the braincase, as seen in modern birds. The fossil possesses the only complete Archaeopteryx vertebral column, including two tiny vertebrae at the tip of the tail showing it had 24 vertebrae, one more than previously thought. The museum last year announced the acquisition of the fossil, which it said had been in the hands of a series of private collectors since being unearthed sometime before 1990. "This specimen is arguably the best Archaeopteryx ever found and we're learning a ton of new things from it," O'Connor said. "I consider Archaeopteryx to be the most important fossil species of all time. It is, after all, the icon of evolution, and evolution is the unifying concept of the biological sciences. Not only is Archaeopteryx the oldest-known fossil bird, with birds today being the most successful lineage of land vertebrates, it is the species that demonstrates that birds are living dinosaurs," O'Connor said. —Reuters

A Roman Gladiator and a Lion Met in Combat. Only One Walked Away.

Gladiators battled lions and other wild animals in the arenas of the Roman Empire. But for all the tales of combat depicted in ancient texts, marble reliefs and mosaics, and then retold in movies and other modern media, archaeologists have never found direct physical evidence, such as skeletons of gladiators bearing animal-induced wounds. At last, proof of classical combat between man and beast has been found in the form of a skeleton from a Roman settlement in Britain. The skeleton was discovered 20 years ago, in an excavation spurred by a couple hoping to renovate the yard of their home in the English city of York. An initial survey turned up evidence of an ancient cemetery, halting the construction plans. 'Britain is rich with Roman archaeology,' said Tim Thompson, an anthropologist at Maynooth University in Ireland and an author of a paper that describes the discovery in the journal PLOS One. 'You pretty much can't shove a spade in the ground without hitting something ancient and archaeological.' The larger site contained the buried remains of more than 80 individuals, and many of their bodies showed signs of trauma. The demographics of the deceased, the types of injuries in their bones and the manner in which they were interred suggested that they had fought as gladiators about 1,800 years ago, when what is now York was an outpost of the Roman Empire. One skeleton in particular, identified by researchers as 6DT19, had unusual wounds: small indentations in the hip bones. Other researchers had noted that these notches looked like bite marks from a large animal, perhaps a lion. To determine if the indentations of 6DT19's hip really were bite marks, Thompson and his colleagues first had to collect data on what the bite marks of large mammals look like. For that, they made a somewhat unusual request of several British zoos: a chance to examine their lions' leftovers. By shining a grid of light on the bones gnawed on by zoo animals, the researchers created a map of the dimensions and depth of the animals' bites. They then created a map of 6DT19's hip bones and compared the bite marks left by the different animals with the indentations on the skeleton. Sure enough, the Roman combatant's injuries were best explained by a lion's bite. However, the hip bite probably isn't what killed 6DT19. 'We think the individual was incapacitated in some way, and then the animal came along, bit and dragged the body away,' Thompson said. — KATE GOLEMBIEWSKI /NYT
