Yes, I have lots of articles, problem is finding ones that I can legally post for everyone to read. I could post lots of titles for you, but again unless you have access to a University database that would not be very helpful. And I quoted the wiki article because well, it is accurate and to the point.
You can choose to believe or not believe my credentials, I can choose to believe or not believe that you had to dash off to a Master's defense (which I do believe by the way). The only reason I offered mine was so that you would operate under the assumption that I had a basic understanding of biology and would not suggest that I consult a general biology textbook. My years as a research scientist have absolutely nothing to do with anemones or reproduction and so I have zero expertise in those areas. I have a pretty strong grounding in biology and a lot of experience in rigorous scientific method, as well as a constant immersion in a community of diverse scientists (from physicists to physicians and everything in between) working together on common questions.
That is all that I bring to this conversation. I saw two sides of a debate that did not seem to be trying to find common ground.
I am glad you are here. Your experience as both a hobbyist and a scientist will enrich this forum. You can choose to believe that your delivery was off-putting or not. There is a very diverse group of contributors here and some of them have formalized science education and some do not. It has been my experience that the presence or lack of formalized scientific education has not correlated with the usefulness of the knowledge offered.
And please dont tell me which conversations I can partake in and which I can't. It's rude.

*puts on TEAM RC hat*
I have to agree -- we (( that is all of us, myself included )) need to try to stay on topic. There is no problem with disagreeing, just do it in a manor that doesn't violate the <a href="http://www.reefcentral.com/index.php/user-agreement">User Agreement</a>. Not saying anyone has does that, just want to prevent it from happening.

Sounds good to me. Again, I apologize if I have offended, not intended. In restrospect some of my comments may have come off as curt, and that was uncalled for and not productive.
And Banff, I appreciate your experience and I would thoroughly enjoy your input. Oh and just to be clear, it was my buddies thesis defense I had to get to yesterday (if it were mine I would have been too nervous to be on the RC boards!) ...it was about mammals..ugh...not really my area of interest lol, but...what are friends for other than to be there to ask all the tough questions in front of your proffs when you are defending your thesis...:smokin:
So back on topic, to sum up where we are at:
All of the scientific evidence I have seen/read indicates that from a biological perspective (atleast in so much as we currently understand), asexual reproduction in anemones *should* be a reproductive strategy utilized during more favorable conditons, that is conditions that are atleast survivable for that individuals genotype.
At the same time, many experienced anemone keepers have witnessed anemones dividing asexually after a *stressful* event. The anecdotal evidence supporting this is clearly undeniable due to the sheer number of times it has been witnessed and interpreted by so many hobbyists.
This presents a little bit of a problem, or perhaps not? I propose that possibly we could be misinterpreting why the anemones are induced to divide. In other words, in my mind I am trying to find an explaination that will reconcile both observations.
In other words, is it possible that what we are interpreting as a stressful event may in fact simulate some of the stimuli that would be percievied as a sign of favorable conditions by an anemone in the wild? I am not trying to implying that they are consciously making a decision per say...
For example, I have a hard time understanding where the idea that overfeeding may be stressful to an anemone, it just does not make sense to me on that basis that an anemone would not eat more than it can/"wants". However, there is obviously some basis to this train of thought, can someone please try and explain it to me?
It seems to me, in order for this approach to result in any clear results, we first need to try and gather all information that we can regarding what if any, quantifiable events occur in the wild to stimulate an asexual reproduction event in the wild. Specifically, I think we should focus on Entacmaea quadricolor at this point.
Now, this is just one hyopthesis, or method of explaination to explore. Does anyone else have some theories we should try and explore?
Thanks.

I do have access to journal databases... :idea:
I dont need a huge list of sources or anything.. I am really interested in the references for sexual reproduction of Entacmaea quadricolor being induced under stressfull conditions or that binary fission is prefered in favorable condtions.. stuff like that.. Thanks! you can PM me wit the info.

Oh perfect! In that case I will be happy to post the names of the titles up here later today when I get a chance.
Also, I have asked the reference lib. about how to legally post a copy of journal articles etc. and I think there is a way to do it, I just don't want to get myself or RC in any trouble lol.

I am working on collecting some info from various cnidarian researchers about the particulars of conditions and fluctuations etc in the regions where various anemone species are found.
If it is not to much to ask, would anyone here who has experience with their BTA's reproducing asexually try and record as much data as possible about the ongoing tank conditions, to include feeding schedule, DO levels, water changes etc. Additionally, please record the local barometric pressure and tidal cycles (if applicable), I am hoping that we can do some good stuff here.
Thanks.

I would be interested in any data on any species of anemones, well at this point, specifically host species of anemone.
Due to the sheer number of BTA's being kept in captivity successfully I think it is the best place to start.
What species are you working with Banff? And, as someone with formal training and experience in neurbiology, how comportable are you with anemone nervous function etc? My knowledge of that area is limited to a basic understanding of their simple nerve net system, however I am curious to learn more about the possible differences in nervous systems beween different species. In particular I would like to explore the possibilty that differences in nerve net repair rates could play a factor in asexual reproduction.
Thanks.

I wouldn't say I am "working with" any species of anemone! I have worked pretty exlusively in higher order mammals for at least 15 years and before that, had a brief excursion into the retinae of goldfish.
In my home tank, I have an RBTA (which splits), a Borneman's (Phymanthus Buitendijki) which splits and an epicystis crucifer which doesn't do much of anything.
My clowns have been hosted by both the Borneman's and the RBTA.
My husbandry practices can only be described as haphazard, I rarely do anything more than about 5 minutes a week of tank maintenance. I only perform water tests if something in the tank looks a little "off" to me.
Somehow, despite all of that, my tank has been running continuously for 7 years now with most of the same inhabitants that started out in there.
I don't think that I can provide a steady-enough baseline for actual rigorous scientific observation. There are way too many variables.
If you want my plain gut feeling based on anecdotal evidence from the individuals in my tank, each splitting event has been preceded by stress. The first time my nems split was when I was on bedrest for 8 months and the husbandry became extremely haphazard (to the point that my husband did not notice that two bulbs in the 6 bulb fixture were actually burnt out). The second time was recently during a hypersalinity event when my top-off went haywire while I was out of town.
