Will feeding make a t molt faster.

With many closed boreders there is not always an opportunity for "fresh blood"


Sooo, where the heck did I promote ANYTHING....I didn't, I simply stated a fact.

come back to planet earth, we are on a different subject over here.

Well the last phrase was an exageration...

I was not talking about you, but in a general manner, sorry if it looked the other way. I was refering to why not to choose a different mate, from a different eggsac, unless the species isn't a recent discovered one, you should be able to find another T pretty easily near you.

You still just write a lot of words...
Just your opinions.
Where is your scientific source?
Show us what you know about the difference in inbreeding in mammals and spiders. Big words, should be easy for you to have something to refer to. If not, you're a troll.

That's the first result searching spider inbreeding...

Inbreeding avoidance in spiders: evidence for rescue effect in fecundity of female spiders with outbreeding opportunity - PubMed

Selection by inbreeding depression should favour mating biases that reduce the risk of fertilization by related mates. However, equivocal evidence for inbreeding avoidance questions the strength of inbreeding depression as a selective force in the evolution of mating biases. Lack of inbreeding...

Obviously there are different studies with different results, but I believe you will be able to find them by yourself.

Thank you.
I did not find the studies. Your "link" lead nowhere. You're still a troll Please post the link to what you're referring to.

Yeah for sure, return to you cave, No troll

You're a troll.
Easy to see. Lots of words, saying nothing.

Please stay in your cave.

Lol, who is the one that didn't provide anything or didn't argue about what is dissagree?

Who is the troll? Who is the one that ask for spoonfeeding without giving nothing in return?

Maybe you feel or believe that you can talk to me again like you did to @Wolfram1 with the plants?

Wow, i didn't realise people were following that disaster.

Anyway while i agree that spiders suffer less from inbreeding the reasons for that can easily be explained. Unlike spiders true-spiders that use ballooning tarantulas are largely dependant on favourable patches and conclaves were they endure, never spreading far or quick. This means many populations suffer from a very limited gene-pool to begin with. This also means that any genetic defects would have killed off affected populations long ago. The collection of specimens for the hobby further reduces the available gene-pool to those specimens we have in our collections. Additionally their mode of reproducing via lots of vulnerable offspring (r-strategy) means any weak genetics get selected out during the years they need to grow and reach maturity.


This means their gene-pool should be largely unaffected by any detrimental mutations. Not unlike lab-mice for example.

Sadly we know that insects and other invertebrates do suffer from a reduction of genetic diversity from inbreeding. A prime example are crashing roach colonies. I wont try to search for other examples but i am sure there are many.

Reduction of genetic diversity thus will not have any direct effect because there are very few defects present in our spiders DNA, BUT (and this is just my worry) our way of keeping them means many of the ones that might have lesser mutation will be able to survive in captivity and even reproduce. Slowly but surely undermining the healthy gene-pool we started out with.

I have no evidence for this but it is common sense.

I don't think it means you absolutely cant pair siblings, BUT why would you knowingly do something that is known to cause problems in lots and lots of other animals. Once we get to the point that our available gene-pool has been reduced and mutated to the point it does become a problem those species might have already died in the wild and there might not be another chance to introduce fresh blood.

Why not give the male away for a breeding loan or sell him and then get another male to breed with your female? It might not matter now but what about the future of our hobby.

Oh... I see now. Thanks for the heads up.
You're referring your statement in your posts to... nothing.

You seemed to be a pretty smart guy...
How hard can it be to back up all your claims with a link to your source?

You're a troll. The AI is getting better, I admit. But you're still a troll.

Small correction, Theraphosidae spiders don't fall into the category of r-strategists exactly because while they produce many offspring with little investment individually they do invest a lot and even provide parental care in many cases, nether can they be characterised by small body size , early maturity onset or short generation time. Weirdly i would say their mix of characteristics seems designed to weed out genetic flaws and endure changes in their immediate environment.

 

[Dorifto]

That's a theory, but, what if the males mature so fast or vice versa to avoid natural inbreeding? Matured males usually would be obligated to breed with females from a previous and a different offspring.

It would be interesting to know if there is any studies about that.

i assume that is the case!
just another failsafe that evolved to avoid genetic defects.

what we are doing in the hobby undermines a lot of those and just because we havent had problems with inbreeding yet doesnt mean there wont be any in the future!!!

"In contrast, after three generations of inbreeding, there was a strong effect on fecundity revealed by a decline in egg number of approximately 35% in the inbred (sib and sib–sib) treatments. We compared the three two-male groups and found that fecundity was completely restored in the sib–nonsib group where inbreeding avoidance could operate. Under a model assuming equal contribution from both sires the expected fecundity would be significantly lower than the observed fecundity in the sib–nonsib group. Hence, when provided with outbreeding opportunities in the sib–nonsib group fecundity was significantly improved compared with the additive scenario of random contribution from both male spiders, explicitly supporting the rescue hypothesis."

Alsoa according to the journal one generation of inbreeding outcome isn't that significant but 3 generations is.

Thanks for the spoon feed, that was good reading

I don’t think it accelerates it a lot and a T won’t eat if it’s not feeling like it, however I feel like T’s I’ve ‘power fed’ just slings, I felt like they did indeed eat often and molted often too, this was prominent in two chilobrachys electric blue specifically, however once the slings even hit over 2 inches it seems like it slows down a little bit, but as super small slings I do believe powerfeeding does work on said size.

I keep molt dates of every specimen and can confirm my gbb subadults molted almost 2 months ahead of average molt sequence after power feed. (3-4 weeks feed cycle prior to power feeding)

Impressive you actually track it, I simply base it on a rough time period and size of the T before, well done.

Thanks, I just like the hobby alot and like to keep records and observation notes hoping to contribute somewhat to this community

To note that temperature also plays part of faster molt cycle but not significant according to Cold Blood. Also the temp difference between now and the previous molt was average of only 1-2 degrees. Unless that's significant enough.

Indeed all my T information is usually through experience or from others here, and you’re doing good things, making observations and collecting the data, I just make the observations and take a mental note

My mental hardrive is too small for that unfortunately.

I'm more towards high humidity with high temps, like in the summer storms, or like their rain season. I also record my Ts molt cicles, and based on previous experiences made a little experiment if having high temps and high humidity levels could trigger a molt, so using a incoming storm, I moisted the enclosures a little bit more than usual, and both Ts molted within a week from each other.

I also factored in humidity in some part of observation and have similar thought as well.
If this is true is that why majority of swamp/moist substrate species molt faster than arid ones like Grammostola?
I would love to read academic writings on this subject.
