Was the complete eradication of Passenger Pigeons deliberate or accidental though?

I'm not sure someone set out to eat every single passenger pigeon with the intention of exterminating them - they just tasted nice

Well, we stated that the people who shot the last flock did so in the knowledge that that was what they were doing. In a court of law that might well constitute mens rea, I would think.

If those naughty Americans and Russians had autoclaved the last two stocks of smallpox virus AS THEY PROMISED then it would have been the first deliberate extinction of a species by humans.

Keep your enemies closer... There's still a lot we're learning from smallpox, particularly about how our own immune system works. Also, someone else may have a stash, and we'd need to make the vaccine, which you can only do from a 'live' culture.

On extinction, there's a great story (from Adams & Carwardine's Last Chance To See about a particular species of pigeon from somewhere in the pacific of which there was only a single male left, and a handful of females. The male wasn't interested in the females at all, so the whole thing looked doomed.

Until someone arrived at the conservation centre who happened to like wearing a bowler hat. The pigeon found this irresistibly erotic for some reason, and frotted itself off regularly on the rim, leaving behind the valuable sperm. It's how they managed to save the bird from extinction...

Yes, we did. Or rather, the cat did, and we made jokes about it.

From a thread about interesting plants on Quite Interestrings:

Quote:

Wood's Cycad

Encephalartos woodii is an extremely rare plant, one of the rarest in the world with no specimens left IN THE WILD (just to make that clear). This plant has only been once found in the wild and now the only known plants left are all male, this plant is on the verge of extinction. Of the 5 remaining specimens 4 have been confirmed as male but the plant in Dublin has yet to cone, however so to call them all male may (hopefully) prove to be inaccurate.

Grizzly put this on the news and it seemed relevant to this thread:

Inextinct

The short-necked oil beetle has re-emerged in South Devon. The insect was believed to become extinct in the 1940's due to damage caused by intensive farming.

The beetle's larvae survives by hitching a ride on miner bees to the bee's nest and consuming the bee's eggs. The beetles were last seen in Sussex in 1948.

In this week's New Scientist:
Quote:

The best evidence for the continued existence of the ivory-billed woodpecker, believed extinct for decades until 'captured' on video two years ago, has been discredited. A video analysis of the common pileated woodpecker to be published in BMC Biology shows it has the colour, pattern and wingbeat frequency thought to be unique to the ivory-bill.

So he's extinct again? Honestly, if it wasn't for bad luck, he wouldn't have no luck at all.

Question: What do the world’s oldest tree, the world’s most isolated tree and the only tree known to have been planted by Shakespeare have in common?


They were all destroyed by humans.

The oldest tree:

In 1964, student Donald Currey was taking samples from Promethius, now known to be the oldest tree, when his boring tool broke inside the tree. He asked for permission from the US Forest Service to cut it down and when he examined it, it turned out to be 5000 years old and the world’s oldest tree.

World’s most isolated tree:

This was the Tree of Ténéré or L’Abre du Ténéré which, in the Sahara desert, was the only tree for 250 miles. Of course, despite being so isolated, a drunk Libyan truck driver knocked it down and killed it.

Shakey’s tree

Shakespeare was supposed to have planted the mulberry tree in New Place, his former home, however Rev. Francis Gastrell was so upset by the number of gawking passers-by hanging around his house that he took an axe to the mulberry tree and cut it to pieces. An entrepreneur called sharp took advantage of the situation though, a man called Sharp began to sell wooden likenesses of Shakespeare carved, so he claimed, from the very mulberry tree destroyed by Gastrell. The number of items supposedly carved from that tree were slightly suspicious though, and co-incided with a sudden decrease in the number of mulberry trees in the surrounding area.

Here's the tree of Ténéré and its lovely new metal replacement.

And here it is as the only tree in the world to figure on a map at a scale of 1:4,000,000.

As was observed in the meeting, the 5,000 year-old tree was the oldest-known living thing in the entire Universe, and they killed it to retrieve a boring tool. Imagine what they would have done for a really interesting one.

“One of the world’s rarest rabbits has been spotted in Sumatra for just the third time in the past 35 years. Grainy images show the small Sumatran striped rabbit nibbling on undergrowth in the Bukit Barisian National Park. The rare species was last spotted in 1972.”
