Well then. For the sake of expediency, I'll respond to just a few points and then ever so briefly. First, making a banal assertion like, "they are solar powered" is not the same as nor a replacement for evidence. What point are trying to make? What observation and of which species informs your opinion? I have only eight species and basking behavior is not consistent nor universal, nor is it adequately described by 'solar powered'.
Vast examples of poor husbandry on Facebook is not evidence for the need for coconut oil; it's evidence for the need for better husbandry. It's still irrelevant to the point.
Are your Russians adults? I ask because it appears their lack of pyramiding is being presented as evidence of efficacy. Do you happen to know if it is possible to generate pyramiding in an adult? I've never seen that.
UVA vision in tortoises is not being questioned. Your assertion that vision includes IR, however, is. Repeating and restating the former is of no utility in supporting the latter.
I like your hypothetical lighting set up. Have you tried it? Does it remove the need for regular oiling? If you're not raising hatchlings/juveniles under those conditions, how do you know?
I have difficulty spending much time following your threads as I find them high on volume and low on clarity, but I have noticed some commonality in your posts, aside from verbosity:
- Poor conditions on Facebook informs the need for oiling.
- charts and graphs of any correlated subjects are entered into evidence (who is arguing for the use of spot lights?)
- sweeping generalities are ignored (i.e. Adult Russians are assumed as representational.)
- your own husbandry is ignored. This is not intended to be mean spirited, but dude, that setup needs work.
Upon review, I guess that wasn't particularly brief. As to the OP and the question of is coconut oil necessary, I'd say the answer is that the need has not yet been established.
My notion of being solar powered, stems around the idea of being completely evolved around the full spectrum emitted by the sun. Regardless of species around the world they all get the same spectrum of water filtered emissions from that sun at varying levels during the day. That is universal. An absolute in this equation.
Indoors strictly, they must live in a habitat that is run solely by artifical lamps. As we do not have the sun indoors, obviously. Thus a big variable in their health lies in this variable of getting the proper light to heat ratio, like outdoors (species specific). The lamps we provide them with (or lack their of) is the only source of the suns spectrum that they would normally receive outside. Wouldn't the most natural habitat be one that stimulates the full spectrum of the outside sun?! I would think so.
I do only have minimal experience in observation of different species, as I only have 2x Russian tortoises. My sample size is not a representation of the population. Nor is it statically representative to drawn correlation by normal standards. But it is what I have to go off. And it does provide me some anecdotal information, that does seem to correlate with others observations and of others research. So I base my best answers off of these.
I never stated vast evidence of poor husbandry on Facebook warranted the need to use coconut oil.. But many of these tortoises are super dry and flaking from the poor husbandry they are in. I always push for better husbandry first.. Always. Then when they ask about their tortoise being dry and flaking or whatnot I always say use coconut oil. I have never stated that coconut oil is a solution to poor lighting schemas and set up. Not once.
Yes both my Russians are adults.. I got both about 4 inches long and they now are 5 inches plus and have gained healthy weight each. I never said a lack of pyramiding in my tortoises is evidence of coconut oil solely, but from my research I have the personal opinion if done in the correct scientific method way using a real statistically sound experiment, we would see strong correlation to coconut oil and decreased build up of beta keratin (scute thickening) and substantial increase in healthy Matrix of alpha keratin to grow rstio.
I have a sound hypothesis to this.
Can I induce pyramiding in a tortoise yes. I believe I personally could. Give it hot baking lights that promote localized heating of the shell past 100f to activate the heat stress proteins embedded in the bets keratin core box,which stimulate proliferation of the shell, add a poor fiber diet, with lack of proper calcium to phosphorus ratio and yes I can almost certain induce pyramiding.
In my opinion I have separated the types of pyramiding in torts. Type 1
Weak bones + severe shell mechanicall stresses will lead to severe deformation.
Whereas type 2 , strong bones (proper diet and micronutrients) will resist the mechanical stresses of the bone only leading to my atheistic pyramiding, like thus seen in nature.
But why the hell would I ever do that? All you need to do is weaken the bones and make the shell proliferate severely increasing the mechanical stresses, expose to super dry environment to unfiltered lamps and boom. Easy. (all my strict opinion)
That hypothetical lighting has not been tried yet. It is what I want to mimic though. It hits all the needed areas of the spectrum and exploits them in full power. But that comes Dr. Baines I believe. My research that I have been working on and is in prototyping stage, is an adapter that connects all these unfiltered lamps to a hub unit and effectively water filters them like the atmosphere does. My friend and I have created an invention that filters these lamps. Literally.
Dr. Baines of the UVguide.uk is going to be very nicely doing a full analysis on this invention we are creating.
Actually my deadline is mid January 2016 to have it in her hands. So very soon I will have the first up and running fully water filtered sun light in my habitat. First one ever.
My current set up is part of set up needed to run my invention, I don't know what upgrades you suggest. But, my habitat is like that for a very specific reason. Other then maybe increasing the size, I have no idea what improvements you see to be done. I have multiple hides, kept humid, I provide shade around all my basking lamps, I provide sight barriers and a microclimate, they are taken out every day to roam the tortoise room, soaked almost daily, my ambient temp is 85f, my cool zoned hides dip down to a cool 75f. And my basking temp is about 98f. And a night temp drop to about 68 to 71f.
What again do you suggest?
Yes charts and graphs are entered as evidence. That is how you build a case and do research. The point of the graph was to show why and how single basking bulb emits a basking 'spot'. Yet these bulbs are the most commonly seen in people's habitat on social media. When I am apart of 7 groups ranging over 30,000 tort keepers u se see a lot of people habitats and lighting schemes. Sooooo many people don't use flood lamps. Just regular incandescent bulbs or non flood lamp bulbs. So that graph shows why, exp to bigger species tortoises it can promote localized heating and poor tissue penetration and why you should use a multiple lamp lighting scheme.
To me you still haven't shown me why coconut oil shouldn't be used in certain instances. In my other thread I lay out what the oil does in much more detail.
