Neoteny in salamanders

[Lilibugz]

Hey all,
I’m a Junior ecology student and we have a semester long assignment over any ecology topic we wish and I’m thinking of doing it over neoteny in salamanders.
Anyone have any good info on the topic? Or good sources to read from!
Thanks!

As a suggestion, see some articles from SR Voss (University of Kentucky) on the genetics of neoteny for axolotl.
For the neoteny of Proteidae, which is different, or occasionnal neoteny of Salamandridae, you'll have to search for other sources.

Oh interesting I’d have thought it was caused by the same reasoning across different species.
I suppose if I were to narrow it down I’d probably go for occasional neoteny. I got the idea from reading an article about a certain population of Ambystoma tigrinum being highly neotic compared to most other populations. I believe it was in a higher altitude or something similar.

Why not.
And if you are interested in Ambystoma tigrinum/mavortium, there are fossil records in Kansas which show Ambystomas were mainly neotenic during glaciations and not during interglacials (as now).
That's for long-term environmental influence.
