Species Extinction Rates Grossly Overestimated
Live Science ^ | May 18, 2011 | Jennifer Welsh

Posted on 05/18/2011 8:17:47 PM PDT by 1010RD

A group of researchers agrees that Earth is facing a mass extinction event, but they are daring to overturn dogma on how fast species are disappearing. The researchers say they have discovered why and they recommend a different way to calculate the rates.

SNIP

We don't even know how many species actually exist, though it is known that biodiversity is declining drastically. Previously estimated extinction rates — some experts thought half the world's plant and animal species would be gone by 2000 — haven't matched what's actually been observed. Other researchers have claimed the difference originates from the lag time between when a species' habitat becomes unsustainable and when the species begins to disappear.

The researchers believe that the overestimation is actually due to how we derive these estimates in the first place.

SNIP

To prove a species is extinct, however, one has to find the last remaining example of that animal. And Hubbell and He explain that the amount of habitat needed to find the last individual is much larger than the amount needed to find the first.

In fact, the researchers mathematically prove in their paper that the habitat loss required for extinction is always larger, usually much larger — up to 160 percent — than the area required for discovery of a species.

SNIP

Another method, called the endemics-area relationship, is more logical, the researchers say.

They tested the two methods using computer models and with known species, including rain-forest plants and birds in North America, and saw that the endemics-area model is a better fit to the actual data.

The researchers warn, though, that this shouldn't lead to complacency about habitat loss. Many species are still going extinct because humans are destroying and disrupting their habitats.

Good and short article once again demonstrating that design of experiments is weak when mingled with funding and political agendas.

Brilliant deduction "scientists/experts", good to know your on top of things.

"Biodiversity".....how I hate that word, too close to diversity!

There is no money for species that aren't dying.

Conflict of interest, but hey, that's science!

Time to remind people that "extinction" does not mean what you think it means. You think "extinction" mean there are no more individual members of a species left on earth--that they are gone, kaput, like the dodo and the passenger pigeon.

This is not what 'extinction' means in the all important politicized scientific slum-world of the environmental wackoes. In that feeble twilight world of assholery, "extinction" means that a local population has disappeared--like from a river, say, or a valley. The same animal/plant may be flourishing a few miles away but if they are no longer present in a given locale, then the envrio-nazis will say they are "extinct."

This, btw, is the language and definition of extinction used by the Endangered Species Act (ESA,) and is the reason these whorehouse versions of scientists get away with such lies.

You can look it up.

Are you saying that the leftist Greenies are lying?

Wow, that’s never happened before.

So, basically, if I don't have anymore beer in my fridge, my beer isn't extinct, I'm just too lazy to get more?

Excellent article, it’s not science, it’s an agenda. Greenies always twist what little “data” to fit their agenda to control every aspect of our lives.

Biodiversity. Wherever that word appears in the context of a region, it is usually followed by a land grab.

THe only species I want to go into extinction are communists, islamis jihadists/fundamentalists, nazis, Democrats and liberals.

Not just on the Endangered Feces list - pure extinction. Darwin would approve.

Besides, I can’t take supposedly educated people who use the phrase “go extinct” anyway. The proper phrase is “become extinct”. So, as long as they can’t speak properly how can I imagine they actually have an education? Idiots.

Thylacine at about 48S.

Certainly carnivorous, doesn't look canine to me.

If we’re not guilty, fearful or ashamed they can’t control us.

I respect all thing that swim, creep, fly, and crawl upon this earth. I mourn the loss of any of the creator's works of living art. That being said, many of the species they are talking about are outside the borders of the United States, and not the concern of our government or our populace. If wealthy people want to save the rainforest more power to them, the Nature Conservancy accepts donations. As someone said the definition of extinction is also in question. For example I love the thought of wild horses running in the Pryor Mountains of Wyoming but if somebody shot every last one of them, there would still be horses in this world, but someone might write that the Pryor Mountain wild horse herd was extinct. Predictions of future events is an iffy proposition especially when dealing with biology. The source of many of these proclamations of eminent extinction are political in nature. Life has a way of surprising academics with its resiliency, so many of these articles are people making some noise to further their own careers.

Biodiversity joins a long list of liberal/progressive memes without meaning.

What is sustainable? What is renewable? These nonsense words rule our world. Words without meaning mean whatever ‘we’ want them to mean whenever ‘we’ want them to.

Diversity, tolerance, and even hate and love are twisted all out of normalcy.

Which I suppose is the goal.

I hear you, but actually the more I read history the more I realize that these nuts have been with us, in one form or another, since the dawn of time.

Has there ever been an era of human history without maniacal control-freaks with a slaver’s agenda?

Add in the fossil record and the history of life on earth is extinction. Which way do they want it - natural or unnatural?

It’s got that goofy tuft of hair on top of it’s head between the ears.

Let me guess... Massive new taxes and regulations covering every facet of the American peoples' lives will stop this "mass extinction event."

Has Al Gore dreamed up a new gig?

Uh.... Of all the life forms that have lived on the Earth, 99% of them have gone extinct.

When something goes, something else takes it’s place. New life is constantly emerging and adapting.

Some species may go extinct in a localized area. It’s hard to snuff out all of a species. But it will happen, and there is not much we can do about it.

Some species will vanish. No matter how much we try to prevent it. Might even be us.

<>I>Ironically, these are the same people who buy into Darwin and survival of the fittest.

The whole 'survival of the fittest' phrase is so ambiguous, but widely used because it is easy for public consumption.

There is a survival of the fittest among species. So far we haven't gone extinct.

Then there is continuation of the genes and traits of the individuals of a species. Those that are most successful usually mate the most. Therefore traits that enable 'surviving' spread around. This causes an evolution in the physical characteristics of the offspring.

I have not mentioned evolution as it applies to how life went from prebiotic soup to present day humans, because I don't think that is what Darwin was addressing, and it's way too complicated to even get started on (at this late hour).

“When something goes, something else takes it’s place. New life is constantly emerging and adapting.”

Absolutely, those constantly emerging new life forms are making it, or not making it. In many cases the struggling new forms of life are documented, and when that life form expires, and disappears mankind is accused of the “extinction” of that life form when in actuality it simply couldn’t adapt in its existing form in the Earth’s climate/atmosphere regardless.

These “experiments of Nature” if you will occur 24/7/365 days around the World. They occur in the vacant lots next door. The jungles in Costa Rica. The deserts of the ME, the Oceans of the World. All over the Earth.

It’s a constant that somewhere right this second various offshoots of existing life are teaming with other variations of existing life creating new life forms, but if those life forms aren’t capable of adapting to the chemistry that is the Earths atmosphere they will expire.

Been going on since the beginning of this Earth. “The strong survive.” “Survival of the fittest.” That sort of thing.
