Failed breeding in CB animals Survey

[froggy]

Hi everyone

I want to know how many people have had problems breeding CB animals. I know this can be a problem sometimes, but I would like to gather some information in one place. I am just starting a PhD on amphibian ex-situ conservation and want to know something of the range of species (at least within the caudata, for this forum) affected by this problem.

So, if people wouldn't mind posting a species with which they have experienced the problem of being able to breed WC animals, but not their offspring, or in getting reasonable numbers of eggs and whether it is one or both sexes involved, I would be very grateful.

Thanks

Chris

I was under the impression it was easier to breed C.B. individuals. I could be wrong but most of what I read seems to support some selection within the parental group.

The only well documented case I know of is the Chemnitz strain of Cynops cyanurus.

Do you know if there are any publications about this case - google scholar and ISIweb don't find anything...?

I was sure that i had read about other people having problems getting either one geneder of CB to breed, or getting many fewer eggs from CB animals than WC....

Thanks

I know that w/c Axolotl clutches are larger than c/b individuals. You could ask Shrom if he has seen a reduction in his colonies clutch sizes over generations but also there are not a lot of well documented reproductive information with regard to C/B amphibians in the sciences. There are only a few amphibian models and the fact that they are, is because they breed well in captivity. You can also contact AGSC and see if they keep stud books.

I checked on this, and there wasn't anything published. It was discussed on various forums.
