“What are you cooking for our guests?” She says. “Whatever you buy,” I say. “You couldn’t possibly shop and cook,” she says. “That’s not the sort of thing you do.” “It’s the sort of thing I do the whole time,” I say. “Make me a list,” she says. “How many people?” “We don’t even have that many forks,” I say. “You stay here and relax,” my wife says. “On no account should you look behind you,” I say. My wife lifts her head from her phone and turns.

“They’ve learned to ignore your fury,” I say. “You don’t belong here!” “So colourful,” I say. “Shut up,” she says. Twenty-four hours later, our guests arrive. *****Invasive species: Love SW LDN parakeet theories: 1) Jimi Hendrix released them. 2) Escaped from Isleworth studios filming The African Queen. 3) Escaped from Heathrow in transit as pets. 4) Escaped frm home of Manuel II of Portugal, exiled in F. *****The great green expansion: how ring-necked parakeets took over London. Electric Ladyland wasn’t the only thing Jimi Hendrix released in 1968.

*****The great green expansion: how ring-necked parakeets took over London

One day in that tumultuous year he left his flat on Brook Street, Mayfair, and strolled down nearby Carnaby Street with a birdcage in his hands. I like to think that he was dressed in a tasselled jacket and flares, his favourite Fender Stratocaster slung across his back. Or perhaps he travelled incognito, in a trenchcoat and dark glasses. Either way, somewhere on that street, the heart of Swinging London at the height of peace and love, he opened the door of the cage and unleashed two bright green birds: Adam and Eve, a breeding pair of ring-necked parakeets.

As they vanished, a flash of tropical colour against the grey sky, passersby merely shrugged: just more hippy weirdness. Unless that story is not true, and actually London’s parakeets arrived in 1951 with Humphrey Bogart and Katharine Hepburn. Unless, of course, that is fake news, and the parakeets owe their current success to George Michael in the 1990s. Nate Berg sur Twitter : ""[The parakeet's] unlikely success can be found in London’s map. The capital –soon to be branded the world’s first 'National Park City'– consists of 47% green space, incl. 35k acres of parks, commons, woodlands, wetlands, cemeteri. *****Invasive species / Introduced species: Cats should not be allowed to roam outdoor, point.

*****Invasive species / Alien species: Debris from the 2011 tsunami carried hundreds of species across the Pacific Ocean. *****Invasive species / Alien species: Tsunami drives species 'army' across Pacific to US coast. Image copyright John Chapman Scientists have detected hundreds of Japanese marine species on US coasts, swept across the Pacific by the deadly 2011 tsunami.

*****Invasive species / Alien species: Tsunami drives species 'army' across Pacific to US coast

Mussels, starfish and dozens of other creatures great and small travelled across the waters, often on pieces of plastic debris. Researchers were surprised that so many survived the long crossing, with new species still washing up in 2017. The study is published in the journal Science. The powerful earthquake that shook north-eastern Japan in March 2011 triggered a huge tsunami that reached almost 39m in height on the Tōhoku coast of Honshu. The towering waves washed hundreds of objects out to sea, ranging in size from tiny pieces of plastic to fishing boats and docks.

A year later, scientists began finding tsunami debris with living creatures still attached, washing up on the shores of Hawaii and the western US coast from Alaska down to California. *****Plastic tsunami debris sent 300 marine species on 'unprecedented' journey across the Pacific (invasive species) A massive tsunami sparked by the huge Tōhoku earthquake in 2011 sent nearly 300 living Japanese coastal marine species on a six-year journey across the Pacific Ocean, leading to a transoceanic migration that has no known historical precedent.

These species, which include mollusks, fish, parasites, and more, have been found residing in Hawaii, Midway Atoll, and parts of the West Coast, from Alaska to California. Some may eventually disrupt pre-existing ecosystems, raising concerns over invasive species. While the tsunami was a natural event, the migration has been aided by humans, since these species were able to hitch a ride across the ocean on non-biodegradable debris, such as plastics. A study detailing the migration, which was published Thursday in the journal Science, examined the biological ripple effects from the magnitude 9.0 earthquake and the subsequent tsunami that struck northern Japan on March 11, 2011. *****Invasive species / Alien species: Never had that suggestion from a @bbcgqt panellist. What's A Native Species? That's More Complicated Than You Might Think. Pay attention to the natural world for any length of time at all and you’ll come up against one of the biggest divides in the life sciences: “native” species versus “introduced” species.

What's A Native Species? That's More Complicated Than You Might Think

It’s a basic concept in ecology. Ecosystems develop with certain kinds of organisms as members, and over time a predictable set of relationships develops among those organisms. Then some new organisms parachute in and change the whole system for a while, until relationships re-evolve and things get predictable again. That process happens all the time in nature, but over the last few centuries we’ve sped up the rate of introductions to a dizzying speed.

Why Doubt Invasive Species Impacts? – National Geographic Society (blogs) Invasive alien species are now found on every corner of the planet and rank higher than climate change as a current threat to endangered species.

Why Doubt Invasive Species Impacts? – National Geographic Society (blogs)

So then why, despite all the scientific evidence of negative impacts from invasive species, would people be resistant to taking action against them? In two scientific papers released this week myself and colleagues have tried to understand why invasive species have such a low public profile compared to climate change, and furthermore why some elements of society would even try to deny that there is even a problem. Professor Tim Blackburn and myself undertook some research on science denialism, and found that some of the articles that have been written in the past year, e.g. in New Scientist, The New York Times and The Economist, indeed appeared to conform to a special case of science denialism – invasive species denialism. *****Threat of cats: Invasive Mammals Are Pushing Native Birds to the Brink.

Cats Among Biggest Threats to Global Biodiversity, Study Finds Contact: Grant Sizemore, 202-888-7480 (Washington, D.C., Dec. 13, 2016) Invasive mammalian predators are killing endangered species around the world at much higher rates than previously known and are “arguably the most damaging group of alien animal species for global biodiversity,” according to a recent study published in the Proceedings of the National Academy of Sciences (PNAS).

The findings are the latest evidence that cats and other invasive species pose a major threat to birds and other wildlife worldwide. A recent study found cats have contributed to the extinction of 63 species worldwide. Photo by Vasily Vishnevskiy. Non-native mammalian predators have contributed to the extinction of 87 bird, 45 mammal, and 10 reptile species, and have helped put another 596 species at risk of extinction, according to the study by Dr.
