2. Ozark, what do you think is the difficulty in keeping them? They are not the average firesal or so, that might be true, but I guess with experience made by the before quoted Hainaux and others, it might very well be possible to keep them. After all, what I found, the keeping part for Bolitoglossids is not the hardest, if you have a slight understanding of their natural living, what kills off the most caudates is the chytrid (which can be treated at least to a certain success rate) and the stress from the export, which could be done professionally. I don't see why you would want smaller Bolitoglossids: they are (I would say) not much easier in care, just need less space. Also, I have never heard of any other Bolitoglossa than dofleini or mexicana being imported by anything but scientists. I had the chance to see a B. rufescens once and have also seen the long-term keeping of it.
I don't think the species is not "keepable", I think there have been plenty of mistakes with it in the past (oh wonder - I heard people kept them like dartfrogs), but as examples show, it is possible, given the luck of getting healthy or at least treatable animals, to keep them.
I know there are lots of Experts, that I would say should do it instead of me, but I strongly suggest the establishment of captive groups. This genus is probably disappearing in the wild (not that much dofleini, but others especially) and attempts should be made to organize at least some remaining ones. It is sad that only few in the hobby care for central or southern american plethodontids, but remember that in the beginning every newt and salamander seemed hard to keep - people had problems with Neurergus, who are now known as one of the more hardy captives.
Just my two cents.
I am not on the search for justifications, that's problem of philosopher's. All I am saying is that a) the wild will not hinder them from dying out b) institutions - except for few like Tim Herman, Mr. Pasmans from Belgium, Mr. Wake, Mr. Raffaelli, and (I don't want to ignore that) surely some more zoos and institutions - do not care for them: they are no pandas, icebears, whatever cuddly, nice to see, impressing animal you can imagine. I've heard from Mr. Hainaux, who got his theoretical and practical knowledge together and keeps them to this day - I have not heard of a european zoo keeping them (maybe I just don't know).
So I come to my ending point, c) Whatever it is, I think the knowledge and possibilities of the hobby are strongly underestimated - institutions like the salamanderland in Austra (RIP) were built by hobbyists. Therefore, I am saying, if you are willing to learn all you need, if you can get together the equipment and knowledge it needs, don't wait for experts to do it.
I don't encourage everyday keepers to randomly buy Bolitoglossids, but that won't be the case anyways, as there are no exports. I just don't think a zoologist oder Professor with only little knowledge is any better than a hobbyist who has gotten together all the articles, books, reports etc. on those animals and their problems. Humbleness is a nice trait, but you should realize when you got knowledge together. If you read my post carefully, I said others are more suited, but I guess I won't be saying that much longer: I've got shelves full of articles and am working through them, I annoy all the keepers or those who went there with my questions and I am saving money to go there myself. I don't think I know enough already, but that is not because I don't have a "professional" title, a PhD from the university or anything. So I can work on it, and then, at one point, I will be as able to keep them as anyone.
I hope noone got angry.
an organized plan to transport the animals back to their native habitat
Are you arguing that one man in his home can have equal or greater success than a fully-staffed institution with the combined knowledge and experience of seasoned veterinarians, animal husbandry experts, and field researchers dedicated to the conservation of species?
Ozark, I am not giving justifications, because this is not a moral, but a practical question, and that is how I am answering it. All you do is state your assumptions: there might be more institutions keeping them, there might be more people in the hobby - how much time did you actually spend on finding out?
I am sorry to tell you, but I am getting the impression you did not really understand the matter with Bolitoglossids at that state. The current situation can hardly allow, how you said it, to have
because fungus and their other treats rage on. At the present state, probably best one can do is a) to found institutions like the CRARC, along with the attempt to get breeding groups of the animals there for serious hobbyists, something like their cooperation with Understory. And b) to keep the species from extinction. There is not much hope for many species now kept, that they can ever be reintroduced.
Do you know how much institutions are willing to spend on salamanders in most cases? Obviously not, because if you compare the dedicated hobbyist, like the ones I mentioned before and many more, even Mr. Hainaux on his small scale, you do not come to the impression they lack anything. In fact, I think it is more often likely that the institutions lack something, namely the WILL, which is, in fact, the very basic requirement.
Your argumentation, it seems to me, does not come from a long involvement into the problems and science of these salamanders, but from the mere argument which derives from the fact that most of the captive attempts failed. I don't want to overrule you, just state, that there is maybe more you can learn about that field.
