UV lights in the care of caudates

Sorry to come back to this late again, but does anyone have any further information about the conference mentioned? I've been trying to find details (including PMing Yagoag), but can't get any more information. Am VERY interested in this information.

Thanks for any help,

Bruce.
 
I think the need of UVB is totally dependend of the species and should not be generalised. I've seen Triturus cristatus hanging right under the surface when the sun was shining or floating a while after taking a breath. Triturus cristatus seems to sunbath regulary, which might be a clue that they really need a high Uv exposure.
When you compare this with the behavior of Mesotriton alpestris for example, you can see a big difference. Mesotriton a., most of the time, dives straight back down when they come to the surface to take a breath, whish can be a clue that they don't really need a high Uv exposure...
Even if you look to the day/night activity of these species there is a lot of difference too. Mesotriton is only active during the days in spring en gets night-active during summer. While Triturus is night-active during spring and day/night active during summer (even hanging under surface by day).
Uv is always present during the day, so every animal that gets active during day (even when it's wet and cloudy) gets exposed to it. Staying in the water during summer, makes it possible to get a high Uv exposure without drying out the skin.
Larvea gets exposured when they eat. Water fleas always group in the sunlight wish makes it easy to catch for the larvea. Exploring their natural behavior and looking at small details could bring a lot answers, if you ask me.
It's a very interresting topic and I'm very curious to which facts it will bring us

Kind regards,

Steven
 
I'm just wondering if anything new came up in this thread. I've been having a black light on my axolotl tank with six 1-year old axies and they have been acting differently than with a normal light. I thought the normal flourescent bulb was too bright for them; that's why I switched to a black light. I've noticed that the axies all pile up in one corner in their hide (a transparent plastic hamsterhouse) as if they are avoiding the glare of the black light. It really doesn't have much glare to it; only white things illumnate through the tank. I've been turning the light off until I know more about effects of black light on axolotls. Can anybody give me any feedback on this? So far my search for articles online ended in dead-end websites that wanted me to pay 30 bucks or more for scientific papers I may not understand anyway. :) Help?
Thanks from a frustrated secretary that happens to love axies. :)
 


Thank you so much for the articles, they were just what I was looking for.

    Had a question that I just want to be sure of. My marbled newt is a little over a year old and has started to develop and I noticed that he is starting to swell a little below his abdomen. I guess I’d like to know if they are his testes or if I need to be concerned.

    Hello!!! I'm new to this website and idk how to ask a proper question on the designated spot yet, so I'll ask here, I'm a first time Axolotl owner, and my dad used to run an aquarium store, anyways... Orca, my Axolotl, seems to loose parts of her toes on one limb from time to time, I can't seem to find the problem. Tempature is well, she doesn't seem to have any infections or anything, though. And I'm not sure if I'll be able to find a vet in Brazil for amphibians that are in a reasonable distance to drive without stressing Orca out too much

    Hello, I’m hoping for some advice please. Our Axolotl is about 7 months old. Till now no problem. Eating, growing and happy. He’s simply stopped eating. Everything looks fine, his gills look healthy and no apparent signs of sickness. He just swims past the pellets and bloodworm like he can’t smell it. I don’t think it’s a blockage either. Any ideas and suggestions for treatment would be much appreciated. Thank you!

    Dear All, I would appreciate some help identifying P. waltl disease and treatment. We received newts from Europe early November and a few maybe 3/70 had what it looked like lesions under the legs- at that time we thought maybe it was the stress of travel- now we think they probably had "red leg syndrome" (see picture). However a few weeks later other newts started to develop skin lesions (picture enclosed). The sender recommended to use sulfamerazine and we have treated them 2x and we are not sure they are all recovering. Does anyone have any experience with P. waltl diseases and could give some input on this? Any input would be greatly appreciated! Thank you.
