So let me get this right ...
A full 20% of the top ten so-called "lost" amphibians aren't actually lost?
Things that make you go "hmmmm ..."
Determined Malaysian scientists have pulled off a bit of a blinder in the search for lost amphibians, by getting the first snaps of the elusive Borneo rainbow toad. Ansonia latidisca was last seen in 1924 by European explorers, and was until now recorded only in sketch form. Responding to an Conservation International call to …
If you read up on evolutionary history, basically everything dies off quite regularly (as in 40-50% of species just disappear) and what doesn't die off evolves into different species to fill the gaps (it's believed that a lot of the "this species is critical to this environment's survival" assertions are a load of crap). The world copes and moves on without that ultra-rare toad which probably hasn't made any contribution to the local environment since it had a population of more than 100,000.
Think about it - if it was endangered or rare, and nobody really noticed apart from the scientists looking for that exact species - how large exactly was the part it played in the local ecology?
The biggest "problem" with species dying off is that they may have stuff we could use, e.g. if certain species of animals die off or kill off some associated plantlife (because it's not longer fertilising it), etc. then we may not find things that plant/animal life can do - e.g. produce human-painkillers, help us locate the DNA segment for property X, let us find missing links between species etc.
Species are created, evolve and die every single day, globally. Unless you can prove that one has a dramatic effect on the local environment or something to really show science, there's little reason to go to special efforts to keep it (artificially, in captivity, in man-made environments, etc.). Do we moan the millions of subspecies of cow that haven't been chosen for breeding because they don't produce a lot of milk or make manky-tasting beef? Not really. But apparently a frog that nobody's seen in decades is "important". Personally, I think you'd have been better off just leaving it alone rather than acclimatising it to human contact which is likely to end up killing it (either because it gets too friendly and runs across a road, or because it catches something from us, or because it starts to feed from human waste and thus becomes a dependent pest).
Every single time humans interfere with species distribution and movement (e.g. introducing cane toads to Australia) we make things worse even if we're supposed to have thought everything through. Now most of the pandas in the world are in zoos - an environment that they are notoriously inept at breeding in, for instance.
Leave the fecking things alone and stop going looking for them. By the time you realise there's only a handful left, they aren't important to the local ecology any more and just become an administrative and financial burden for zero practical gain except for some PETA nuts to go "Aw, we saved him!" until the animals die in captivity.
...that very fragility that makes amphibians the "mine canary" of ecosystems.
We have no way of knowing what traits,chemicals, abilities. etc. are coded in the DNA of any living thing, nor how important these codes will be to us in the future.
From a personal standpoint, I very much enjoyed a photograph of the most amazing camouflage that i have seen; this animal WANTS to be lost.
As I recall, a few years ago everyone was worried about the inexplicable loos of amphibian, and were blaming pollution, climate change and habitat loss. Then they discovered the fungus. By which time I'm sure eager researchers have managed to spread it into many areas it would never have got to.
Lets hope the people that have been looking for this toad didn't take the amphibian killing fungus with them on their boots. It's probably the fact that it's been 'lost' that's been keeping it alive in the first place.
Sometimes less is more.
The world copes and moves on without that ultra-rare "Lee Dowling" which probably hasn't made any contribution to the local environment. Dowlings are created, evolve and die every single day, globally. Unless you can prove that one has a dramatic effect on the local environment or something to really show science, there's little reason to go to special efforts to keep one (artificially, in captivity, in man-made environments, etc.).
