Lemming Population Flux Solved: Mass Suicide Not to Blame
quogmire writes "Australia's ABC reports that biologists from the Universities of Finland and Freiburg (Germany) have finally solved the question of lemming population fluctuations once thought to be caused by lemmings mass-suiciding by plunging off cliffs. 'Lemming populations, they say, surge spectacularly and fall just as quickly, thanks to the combined feasting of four predators: the stoat, arctic fox, snowy owl and a seabird called the long-tailed skua.' The original article (Login required) is published in Science."

Thanks scientists, for destroying the magic behind my favourite game.
C'mon scientists, usually you replace our understanding with something much more intricate and complex. But now you replace a fun story with something much more boring. Couldn't you have kept it to yourself?
I thought it was because I should have had one build that bridge across the chasm. I didn't consider that the game had predators as well.
What? There are STILL people that believe that lemmings mass suicide?! Geez, what a hoax.
It's well known, by me at least, that the whole 'lemming suicide' thing was something that Disney cooked up during their 'bad documentary' era. In this case the lemmings were hearded off a cliff by the documentary crew, and was filmed as a 'mass suicide'.
I've seen some pretty amusing/sad documentaries that came out of Disney, including one that had the antics of a Jaguar eating various creatrues. It was OBVIOUS that it was a jaguar in a rather well done habitat where they threw in various animals, mostly eels, for the jaguar to attack. It was exceptionally amusing, but sad, too, that they thought to do something like this and pass it off as truth.
those Disney lemmings didn't commit suicide, they were MURDERED! *gasp*
I mean, dumping lemmings of a cliff from a truck just for shooting a nature document.
So is the old Psygnosis game now obsolete and environmentally incorrect?
What about dying inside of a promiscuous person's clenched asshole?
I'm sure alot of lemmings die horrible deaths that way...
See you space cowboy...
The snopes.com link is really shocking. I notice it dates to '96... I'm surprised I hadn't heard about it until now.

Lemmings jump because of Disney
If masturbating to Bugs Bunny in drag is wrong, I don't want to be right.
This is news?
Sheesh, I mean it's been known that any population boom in prey will boost the predator population, which will reduce the number of prey animals, thus reducing the preditor numbers for years.
So it applies to lemmings too. Big surprise.
I guess I can sleep now that I know the mystery behind lemming population flucuations.
Under capitalism man exploits man. Under communism it's the other way around.
This doesn't concur with the results I got from my private investigations regarding the behaviour of lemmings. I did some massive computer simulations during the 90's, which showed that lemmings are stupid animals which will walk into one direction until they fall off the cliff. Only few of them can use jack-hammers or parachutes, and even that not without explicit order.
According to some urban legend, the film makers induced lemmings into jumping off a cliff to "document" this behaviour. Interestingly, according to Snopes, this appears to be actually - true!
I guess the credits didn't include the claim "no animals were harmed during the making of this movie"... :-(
'Lemmings were induced into jumping off a cliff for this Disney nature film'
...surely there's SOMETHING else more worthy of study.
Losers choose to abuse the use of "loose".
*puts hands on head* Oh-no!!!
*POP*
I mean really, who gives a rat's arse about the Lemmings population flux??!
If the Lemmings were running Linux or if the researchers found the solution playing the Lemmings videograme then maybe I'd be midly interested...
I just sent in a check for all 3 of our Linux servers. Now I can legally use my Linux servers.
Thanks SCO!

I'm pretty sure there's no such thing as the "University of Finland". At least, I've been living in Finland for the past two years and I've never heard of it.

Chaos theory was in part defined following studies of populations of just TWO animals, the arctic hare and the the Canadian lynx. This was around 1989.
So why should it be surprising that populations of lemmings are chaotic?

I suspect that the human population will go through a similar cycle. Exponential growth, exceed the carrying capacity and then population crash. We're seeing it at the local scale but with globalisation, I don't see anything to stop it on a global scale.
At the moment, the western industrialised nations are fairly steady state but the developing and 3rd world nations are definitely not. We can look forward to wars over resources in the relatively near future (have they started already, iraq just the prequel?).

Apparently it has also been found that when the lemmings do jump off the cliff, they all have little umbrellas to make it down safely.
But I just wanted to point out that the ABC article is somewhat misleading. The original research article at no point addresses or attempts to refute the mass-suicide myth. Because, honestly, no scientist believed that was possible. The question they considered was much more reasonable: do the large deviations come from predators eating lemmings, or from a lack of vegatation for the lemmings to eat? It seems as though they have resolved that the crashes in population come from predator over-population, not from food scarcity.
This article will probably not shake the foundations of population dynamics. As some other posters have pointed out, it is not so surprising that one sees immense highs and massive crashes in a predator-prey system, because these phenomena exist even in simple mathematical models of pred-prey systems. So for a mathematician this should fly right under the radar.
On the other hand, to a population dynamics guy, this is somewhat interesting, as in that field it is typically considered hard to model these dynamics accurately. It seems as though these guys have determined some parameters in the population dynamics model experimentally, and this is what it is interesting.

Now that we are discussing suicide, and how we had a whole messed up definition of what the suicider-lemmings were doing, I wonder if we have a similarly messed up understanding of the suiciders ...
... but whatever ... basically the question that pops in my head is whether the operating definition of a suicide-bomber that is currently in vogue is comprehensive or not.
... or at some other level that is atleast higher than that of a boot in the face.
I know that POTUS has defined it in pretty much black and white, and the LUNATIC calls them the deadenders, the military calls them operatives
And the analogy with the lemmings is whether the use of a suicide-bomber as a strategic and assymetric weapon of war is something that may make sense when the analysis is done at the level of survival of not individuals or groups but at the level of cultures

FUCKING HELL, you are cool!
I love you...
I wonder why it took them so long to come up with a model for lemmings' weird population behavior. I think such "boom and bust" cycles have also been observed for caribou and the arctic wolf. A rise in the caribou population causes a corresponding rise for wolves and both fall dramatically afterwards. I'm not completely sure about this, so please feel free to correct me here.
Also, it is interesting that suicidal behavior among animals does exist. This Everything2 node provides some very interesting information about this matter.

Apart from the "University of Finland" and all the cutesy Lemmings jokes, does this strike anyone as horrificly unscientific? I mean, it's been observed for ages that the growth of the population of the prey causes a growth in population of the predator. Then your population growth for the lemmings looks something like:
dL/dt = bL/2 - hP
where L is the lemming population, b is the average number of lemmings born in a time interval, P is the number of predators and h is some constant. P on the other hand is related to L by some observed relation:
dP/dt ~ L
Given suitable values for b and h we can predict the behaviour of the lemming population without having to invent catastrophic events to explain the fluctuations of L without any empirical evidence to support them.
Nope..but then I realize there's actually a real world out there.

This new study needs to be focused on the slashdot lemming and how the groupthink slashbots started and evolved.
Back in the day, THE thing to study at university was Chemical Engineering, since graduates were in high demand and earned a fortune.
Guess what ? 3 years later, there was a glut and they couldn't find jobs.
Parallels with today's job market anyone ?
Parallels with lemming population ?

Could someone mod the other Lemmings jokes down to -1, so the first one everyone sees is this one?
Ta,
A popular survival strategy for many insects is to synchronize their breeding so that they produce a huge number of offspring within a short period of time. The predators can stuff themselves silly but there are plenty of survivors.

Actually, that was the first thought that came to my mind.
"I thought Lemming blew themselves up in the game... wait, why is the Science journal publishing this crap?... Oh, they're talking about the real Lemmings."
In US, you can easily buy enough major firearms to wipe out your neighbourhood but a few little fireworks are banned.
Sorry to spoil it.
I might also point out that crime and violence are seperate issues. One is a behaviour and the other is a violation of a code of behaviour.
Boxing is not a crime. Boxing is violent.
Violence can increase as violent crime decreases. There is no logical connection between crime and violence, only a social connection based on local mores.

In fact Finland does have many universities. A great many when you consider it only has about 5 million people.
Yes, Finland is practically swarming with academics.

What does a story about lemmings have to do with Linux and OSS?????
We need more topics on why companies should release their products into the public domain, and err, um, nevermind...the subjects are related.
Companies fail because there are more predators feeding on them...not the lemming mantality that leads them to jump off cliffs.
In case you missed the Disney version, Killime was the youngest and the bravest of the lemmings. He was soooo cute! He tried to stop the other lemmings from going over the cliff, but slipped and fell to his death screaming "D'oh!".
"Time for another upgrade/mass-migration!"
Sigh again: the comment on the original post says: unversities of Finland and Freiburg, as in two universities, not as in "all the universities of Finland and that one from Freiburg, Germany". Also in the original abc post it's "university of Finland". It should read: Ilkka Hanski, University of Helsinki, Finland..

If you mod this up, your slashdot background will turn into a beautiful sunset!
Poor countries whose population attempts to grow without bounds will either self-destruct, export their people, or attack their neighbors. Self destruction solves the local problem, although the suffering involved is horrid. Emigration to a richer country will convert their progeny to the no-growth standard. Attacking a stronger country results in defeat of the weaker with consequent loss of life and possible conversion of the poor country to more rational behavior.
In short, world-wide dramatic human population cycles are unlikely.

Universities of Finland. And I'm sure that Finland have several universities.
I'm afraid you misread that. The post says "Universities of Finland and Freiburg (Germany)", while the ABC article says "University of Finland, and Benoit Sittler of the University of Freiburg in Germany."
The university in question is the University of Helsinki, Finland. (I have university access to the Science articles.)

With all due respect, the problem of predator/prey relationships was solved with differential equations decades ago.
They demonstrated the idea of equilibrium was not the norm and that, even if it was magically set, fluctuations would rapidly develop.
As the predator population grows, it begins to kill off too much of the prey. As the prey population dwindles, the predators start starving. Eventually a significant proportion starve off. Then the prey population, freed, bounds back. The predators then start to grow again, this never-ending double sign wave of population vs. time, one's population following the other.
