Ancient Human Trash Heaps Gave Rise to Everglades Tree Islands, Res...

ScienceDaily (Mar. 21, 2011) — Garbage mounds left by prehistoric humans might have driven the formation of many of the Florida Everglades' tree islands, distinctive havens of exceptional ecological richness in the sprawling marsh that are today threatened by human development.

A new study published in The Journal of Ornithology shows house cats to be the number killer of wild birds.

“Cats are way up there in terms of threats to birds — they are a formidable force in driving out native species,” said Peter Marra of the Smithsonian Conservation Biology Institute, one of the authors of the study.

The American Bird Conservancy estimates that up to 500 million birds are killed each year by cats — about half by pets and half by feral felines. “I hope we can now stop minimizing and trivializing the impacts that outdoor cats have on the environment and start addressing the serious problem of cat predation,” said Darin Schroeder, the group’s vice president for conservation advocacy.

Tool making andtool maker using by birds

 

The Egyptian vulture does so with a special technique – it uses a tool, and is one of the few birds todo so. It picks up rounded stones in its beak and uses them to hammer the egg shells until they crack. Even ostrich eggs eventually give way. But the vultures don’t always get to enjoy the fruits of their labours. Yosef found that on at least three occasions, a pair of ravens, watching nearby but hidden behind a bush, quickly flew in and drove the vultures away.

 Yosef thinks that the ravens he saw are the same individuals – they behaved in virtually the same way from one robbery to the next. Their behaviour suggests a keen intelligence. Yosef writes, “Most apparent in the ravens is their innovative thinking and ability to predict the actions of the potential host or prey.”

He thinks that the ravens recognise that ostrich eggs are valuable food but that they cannot break through the shell. They seem to understand the vultures’ technique. They know they have to hide and “be patient”, waiting till the vulture has broken the egg before showing themselves. They know that by hunting together, they can effectively exploit a source of food that they would never be able to reach.

This is possibly overstating the case, at least without putting the birds through any experiments. Animal intelligence is a notoriously tricky thing to study and many previous claims have been overplayed. For example, are they biding their time for the vultures to finish, or are they simply attracted to the glisten of exposed egg whites?

Nonetheless, it’s hardly far-fetched to claim that the ravens are acting intelligently. They and their relatives – crowsrooksjays and bowerbirds – have demonstrated impressive feats of behaviour time and again. In the same nature reserve, Yosef has found that brown-necked ravens cooperate to hunt a local lizard called a mastigure. When the lizard is away from its burrow, a pair of ravens circles in and blocks the entrance. With its escape route cut off, the lizard is attacked by the other ravens. Only when the lizard is dead do the burrow-blockers join the feast.

Ian Enting on Climate science and public debate

Category: Global Warming • Plimer
Posted on: March 20, 2011 8:27 PM, by Tim Lambert

Ian Enting, author of Twisted: The Distorted Mathematics of Greenhouse Denial and the definitive list of errors in Plimer's Heaven and Earth has a talk on Ockham's Razor on the public debate on climate science:

the central issue is that if there was a real case against a significant human influence on climate, why is so much of what passes for public debate based on fabrication? If Ian Plimer had a real case, why does he misrepresent the contents of dozens of his cited references and fabricates so many of his graphics? More importantly, since Plimer is only one individual, if his fellow pseudo-sceptics desire scientific truth rather than just manufacturing doubt, why don't they explicitly dissociate themselves from Plimer's conduct?

Useful link! Doone, do you agree with adding it under "library" or something?
Comment by A Former Member on March 19, 2011 at 6:37pm
Adriana, could you possibly add this to the homepage, like under an "external links" section, or something. It's not really a discussion. More like a database: Women in Science, from The Smithsonian.

I will post Hope's video in the welcome box of the main page. There is a TED conference by the director of the project behind thid film. I'll add the lf I can find it).
