UVB and Amphibians... Theory and Musings

[Saedcantas]

I think I'll collect links to other relevant discussions in here


- Lighting is not always as simple as one being a higher %, you get what you pay for (usually!!!)

- Amphibians know what they need better than we do, here's some evidence!

that is absolutely brilliant and i totaly agree,with everything you said as myself i keep and breed poison dartfrogs and most allready have u.v compacts on them and i'm working on the rest,and through my 11 years exsperience i can honestly say that it improves there cordination,appetite,breeding readiness,healthyness of tadpoles..no spindly leg ever! and colour's for example a pale orange Oophaga pumilio nancy turned bright red over the corse of 1 month,and i have also known for a long time that to much vitamins can overdose as the frogs can't metabolize all of it and can cause damage to intestal tract and liver..plus certain plants need it especialy orchids to remain compact and produce fully coloured flowers,also sometimes a good cue is with the animal being nocturnal or dirunal is that a lot of animal species have dark patches on there skin so as to absorb the u.v rays faster say as in a nocturnal animal that comes out at dusk..and anyway out side everything's exsposed to the sun at a time so are exsposed to u.v rays

An interesting read saedcantas however I must aproach the nocturnal animals with an opn mind, while I am a beleiver most animals plants e.t.c benefit from some part of UV/A and UV/B is it the case with a gecko for e.g. to not live a healthy life without U.V

Not wishing to argue because there are some interesting points there and there are still many wonders within the hobby that need exploring and providing as naturalistic setup as possible in my view is of vital importance.

I am sure amphibians would benefit from UV sources in the wild however slight or short this might be and am sure it would benefit them in some way.
What has interested me also is the possibility of an overdose of vitmain d3 synthesis..

What kind of things would show this and how would it affect an amphibian for e.g. as I am sure in there natural enviroments they would lurk out of sight into forest floors and trees to avoid over dosing and in some cases crisping to death lol, and nature takes the 8 12 hour on its own... some places of the world are dark e.t.c and even some wild animals live within caves for the most part of there lives and I have even herd because of this they begin to loose there colours if there is a good food supply there is really no need to move around... anywho I am now just yapping.

So how long would you leave the uv on for in captivity 3-4 hours a day or even an hour for ---noctunal species haha or what about natural light filterd in through a window? would you agree that they can still benefit from day cycles that way.

There is much to be explored I am not making digs I would be interested in some of your views though.
And you must have good fun with what it is you do lol

Thanks Dixon

Thanks for your comments Dixon, to be honest I think the answers to some of your questions were in the original article, might be worth giving it another read (particularly regarding overdose of D3 synthesis which is not physically possible, as outlined in the article.)

Regarding 'nocturnal' geckos and UV exposure, this paper is a great read, the abstract says it all ;
http://www.reptileuvinfo.com/docs/vi...exas-spiny.pdf

We use UVB tubes/bulbs at normal photoperiods, 12hrs standard and varied across the year.

I'm currently breeding nocturnal geckos for release to the wild in March, I'll post up the pics of what kind of UV levels they deliberately expose themselves to in the wild, once i'm out there working

Okay will do thanks for the link
Should enjoy having a good read through that: probs going to take a while lol.
I was wandering it would kind of be impossible in the wild to overdose on d3 lol I was just wandering what kind of effects it would have in theory,
and oh that should be an interesting experiment for geckos in the wild p.s I want your job.....

This is such an encouraging thread, the amphib keepers are opening their eyes to proper clinical research and the animals will benefit accordingly, I could if required post my article on lighting planted terrariums from P.R.K a few months ago if you think it may he helpful

I can confirm that as a company Arcadia take professional husbandry and healthcare extremely seriously, we are constantly kept up to date with the newest and most trustworthy research. We also have a vested interest in being the industry best.

I can confirm that proper amphib lighting is being looked sensibly at and we hope to help all keepers accordingly.

Please feel free to post any questions to me public or p.m and I will do my best to help.


I just wish the snake, Leo, and crestie keepers were all so open minded to scientific fact as you guys.

any read is a good read why not I dont think this is just the case for amphibs either, I am still open minded about the geckos but I am willling to try it, and observe there behavior myself.
I also look forward to the ops feild study which will be interesting in regards to the geckos, I have really only ever owned one frog but wouldnt mind a few, I have seen some wonderful setups and it would look really good in our sitting room if I was to fund a something like that, anywho please do post the link

Hi John,
I missed this article as I didn't buy that months edition of PRK, are you able to post here or advise which monthvthis article was printed so I can get a back issue?

Many thanks
Ben

Hello, yes it was november 2010, I will be revisiting this feature this year with new tech and live study info, be prepared for Arcadia to lead the world on amphib and invert lighting firm the end of this year!

Brilliant, thanks John, going to order a back issue now
