Europe bans neonicotinoid derogations granted by Member States

Europe bans neonicotinoid derogations granted by Member States

The 27 EU Member States are not entitled to derogate from the EU ban on neonicotinoid seeds, the European Court of Justice ruled on 19 January. This applies even in exceptional circumstances.

The ruling follows an application to the Belgian Council of State to annul Belgium’s derogation for the use of bee-toxic insecticides on sugar beet crops. The application was filed by the activist groups Pesticide Action Network Europe, (PAN Europe), the association Nature & Progrès Belgium, which raises awareness and informs the general public about environmental and societal issues, and a Belgian beekeeper.

The CJEU ruling reshuffles the deck and gives new hope to environmental organisations, as the institution recalled that the ban was adopted “because of the high acute and chronic risks to bees from seeds treated with plant protection products containing these neonicotinoids”. Since 2021, despite protests from associations against successive authorisations, neither the government nor the courts have followed them.

Neonicotinoids have been banned since the end of 2018 in the European Union because of their danger to biodiversity and human health. Eleven countries continue to grant “emergency authorisations” to stakeholders in the sugar beet sector, who are struggling to find alternatives. According to a recent PAN Europe report, EU Member States have granted more than 236 derogations for banned pesticides in the last four years, with neonicotinoids accounting for almost half (47.5%).

Anti-pesticide groups have argued that neonicotinoids are increasingly used preventively by ‘seed coating’ instead of being sprayed on the crop. This means that they are applied directly to the seed before the plant is even infested with pests.

Not surprisingly, today’s ruling puts an end to almost half of the derogations granted by Member States to banned pesticides.

The French government was planning to grant a derogation for the third consecutive year, in 2023, to sugar beet growers using these substances. It will have to abandon this project, now considered illegal by the EU.

New Study Refutes Current Timeline of Mammoth Extinction

New Study Refutes Current Timeline of Mammoth Extinction

Experts suggest that DNA found in sedimentary deposits likely originated from long-deceased animals.

The mystery surrounding the exact timing of the extinction of mammoths has long captivated paleontologists, as the decline of these giant ice age creatures seemed to coincide with the arrival of humans in North and South America.

This has led many to question if human activity played a role in the extinction of mammoths over 10,000 years ago.

University of Cincinnati paleontologist refutes the latest timeline published in 2021 in the journal Nature that suggested mammoths met their end much more recently than we believed. An international team of researchers examined the environmental DNA of mammoth remains and more than 1,500 arctic plants to conclude that a wetter climate quickly changed the landscape from tundra grassland steppe to forested wetlands that could not support many of these big grazing animals, driving mammoths to extinction as recently as 3,900 years ago.

But in a rebuttal paper in Nature, UC College of Arts and Sciences assistant professor Joshua Miller and co-author Carl Simpson at the University of Colorado Boulder argue that the environmental DNA used to establish their updated timeline is more complex than previously recognized.

“The issue is you have no idea how old that DNA is,” Miller said. “Sedimentary deposits are complex. Materials of different ages are routinely buried together.”

Researchers have many tools to date sedimentary deposits and the materials contained in them. But not everything can be dated, Miller said.

“We can radiocarbon date all kinds of things: bones, teeth, charcoal, leaves. That’s very powerful. But currently, we can’t independently date DNA found in sediments,” Miller said.

From recent discoveries like the baby mammoth found in Canada this year, we know that many ice-age animals that died tens of thousands of years ago can become mummified in the arctic’s dry, cold environment. Miller said researchers can’t tell whether environmental DNA preserved in sediment was shed from a living or dead animal.

“DNA is shed from organisms all the time,” Miller said. “In fact, DNA continues to be shed long after the animal dies. In places where decomposition is slow, that means long-dead and even long-extinct species can continue to make their way into surrounding sediments. In the arctic and other cold-weather places, it can take thousands of years for something to decompose.”

The researchers say the slow decomposition of animals in arctic regions could explain how mammoth DNA is showing up thousands of years later than the most recent mammoth fossil discovered. The paper notes that the mummified remains of elephant seals near Antarctica can be more than 5,000 years old.

Simpson said his work studying marine environments from recently eroded hillsides demonstrates how difficult it is to date ancient specimens.

“Seashells can sit on the seafloor for thousands of years. When you see shells on the beach, some could be from animals that died recently while others might be from shellfish that died millennia ago,” Simpson said. “This happens in the vertebrate record as well.”

Miller said the question remains what impact, if any, humans had on the global decline and extinction of mammoths. Humans were known to use fire to alter landscapes in profound ways, Miller said. They also hunted mammoths and made use of their ivory tusks.

So when did the last mammoths die off? Scientists say most mammoths went extinct more than 10,000 years ago, but remnant populations lived on islands such as Russia’s Wrangel Island until much more recently.

This cohabitation with modern humans is one reason mammoths capture our imaginations, researchers said.

“They’re tantalizingly similar to animals that live among us today,” Miller said. “We can almost touch them. That makes mammoths really alluring. For many people, they are the poster children of ice age megafauna.”

Simpson noted that mammoths once lived on the Channel Islands of California near where he grew up. The islands were home to a pygmy mammoth weighing 2,000 pounds. Today, the biggest mammal on the island is a tiny endemic fox.

“I think about how amazing it would have been to grow up with all of those big animals walking around,” Simpson said. “But I just missed them.”
