Extinct Wildflower Found In California

Del writes "A Berkeley graduate student found the pink wildflower Eriogonom truncatum, known as the Mount Diablo buckwheat. The flower hasn't been seen for 70 years and has been rediscovered on the flanks of Mount Diablo in Contra Costa County."

So what, botany nerds/geeks don't count?

Just goes to show

I imagine plants must be incredibly difficult to "declare extinct", after all - how would you show for sure that none are present in a country the size of America? Whilst plants may seem to be local to a specific area because of their preference for a certain type of soil, pH or shade, it doesn't follow that, because the ones you know about are dead, then the plant is extinct. It's too easy to rush to judgement, especially when environmentalists have an interest in declaring loudly how many species are threatened or are already extinct. After reading "A State Of Fear" recently, and whilst I haven't fallen for all of Crichtons selective misrepresentations, I suspect their motivations a bit more than I used to.

Re:Was it rediscovered OR did it re-evolve?

[SubtleNuance]

Just because some particular life has evolved away (become extinct) doesn't mean that it can't come back given the right conditions

I have two problems with this.

1) It suggests that HUMANS arnt responsible for mass modern extinction, just 'changes in the holes'. Thats nonsense. We are destroying the natural world, in such a way that we are removing these niches that plants and animals formerly occupied.

2) once a plant is gone it doesnt 'rematerialize'. Its genetic advantages are lost forever. in the case of this flower, it didnt just 're-appear in a jiffy' to fill the old niche. it A) probably existed all along or B) formerly dormant seeds germinated and multiplied.

What didnt happen is one plant, sensing the niche vacant, didnt 'give birth' to the SAME species as had been extinct.

Its the same flower. not a newly created flower the same as the old one (?) or someshiat.

I don't see the problem with extinctions.

Extinction is the history of the earth. If a species is unsuitable for it's environment it dies out and is replaced by something else. Contrary to popular belief, no species has a right to exist.

It would only concern me if key species that humans depend on were dying out.

Contrary to popular belief, no species has a right to exist.

How you frame a problem determines your policies and actions. This is the most incredibly misguided way of looking at this issue imaginable.

What we are talking about can be framed in terms of human welfare, in the short, mid and long term.

The loss of species is a loss of information; not just the information that is contained in the germ plasm, protein and anatomical structures, but information that is inherent in how that species fits into the ecological systems it has evolved. The relationship is two way -- loss of species decreases the information in the systems it is embedded in, loss of systems complexity leads to loss of speices.

Leaving aside issues of bioprospecting, you might ask what this has to do with human welfare? The answer is, a lot. When species composition changes, ecosystems find a whole new set of equilibria. Sometimes this benefits people, sometimes it hurts. More often it hurts because the opportunistic species are seldom economically valuable, and in many cases pose the potential for harm.

I'll give you a concrete example that covers both these cases. A friend of mine's family own an island, that has been in the family for well over a hundred years. Up until the 1980s, humans were the only major predators on the island, which meant there was a large deer herd -- a good thing. On the other hand, there was a large population of small rodents like meadow voles. The deer population is kept somewhat in check by human predation, but there is no such check on the rodent population. Since everything must be in the end food for something else, this meant dieases organisms and parasites: Borrelia spirochetes and ticks on the scale of a biblical plague. As a result, his family has had a decades long history of health problems: palsy, myalgia, fatigue, join pain etc., that was unexplainable until 1975. Lyme disease.

Shortly after the rediscovery of Lyme disease, it also happened that the Eastern Coyote made it out to the island. As a result the deer herd dropped, which was bad, but the population of rodents and ticks crashed as well. You can now visit the island for a week or more, tramp through the grass and woods and not find a single tick. The thing is, the coyote is filling in ecological niche that was formerly filled by wolves, extinct in this range for centuries. In fact Eastern Coyotes are relatively more wolf-like than their wester cousins, all the better to take the mantle of number one top tier predator.

It may well be the case that the reason that Lyme disease was so poorly characterized before, and so common now, can be explained by the biological impovershment of suburban and non-old growth forests.

Similar issues surround hanta virus and other "emergent" infectious agents. Why do the emerge? Well, they emerge because human progress is not undertaken with sufficient sophistication to minimize unintended consequences. People get their nose bent out of shape because they'd rather not think that their actions have unintended consequences. Well, in the long term and maybe not so long term, knowing the consequences of your actions is smart.

You must be kidding! This is California. Most likely, environmentalists would displace all residents within 100 miles of a buckwheat plant and raze their homes to make sure it isn't threatened. Next, they'll lobby for a "Mount Diablo Buckwheat Awareness Week" and "Mount Diablo Sensitivity Training" in all grade schools and corporations.
