Re: The Importance of Letting Frogs be Frogs?
Ed does a fine job above of emphasizing how well-removed from any sort of "natural" dynamic frog selection is in captivity - but Tarantula Guy, you make a good point about the value of frog populations that do well in captivity, too.
There is an inevitable tension in a hobby centered on the husbandry of rare or delicate critters (and I include plants in that definition - I also grow rare and unusual bulbs). On the one hand, natural populations are spared pressure by readily available domesticated populations.
The momentum of domestication, however, has its own direction. We see this in Agave species where some plants are only available in forms that offset prolifically but never attain the size & maturity of the typical wild-growing specimen of the same species. Offsetting has been highly selected for since it allows growers to propagate immature plants - but the offsetting habit interferes with adult development.
That means the on-going domesticated stocks will need back-crossing from wild populations... and the larger the domesticated breeding effort becomes, pressure on the wild populations could eventually return as more breeders (especially the conscientious ones) try to find "wild genetics".
