Yes I wrote that...and apparently you did not read my post clearly, succinctly or with full understanding of what I posted...read it again. It is not "what we see" that is argued, but its interpretation, and that is where your misguided. Read it again, and you will see nowhere do I post about simple social behaviors vrs complicated social behaviors = that is hilarious!! There is no such thing - all behaviors are neither simple or complicated - but responses to their environments and to conspecifics/environment in their domain. You see varanids next to one another in an artificial environment, and expect this to be a 'wild' natural scenario when you yourself have said captivity is an artificial environment. Wild behaviors can be observed in captivity, yes, but not all of them are natural, or are they?? This is a thin line of contention, and as the postulates state, can be determined, along with a multitiude of other parameters (that I do not think you are aware of - and it would take a considerable amount of reading to absorp), but merely seeing animals together does not EQUATE they are social? It can be "suggestive" of such behavior, but does not imply it strickly - that is too easy (= your phrase, 'simple social behavior'?). Read the postulates and think about them frank...
Are varanids gregarious? No. Do they learn from one another in a social grouping? no. Are they clustered together in high population densities in wild? No. Do they learn and adapt? Yes.
Do they mate with conspecifics/relatives? (probably-) No. Do they share nesting with conspecifics/other animals? Yes; does that make them social? No. The list goes on and on, and it would take a considerable time to do this and don't feel like it, but go ahead if you like? Back to your comment: "We see it"; the adjective being 'see'...Yes you see them together, but is this always associated with another behavior? Breeding/courtship behavior?? If it is so, then it is apart of reproductive behavior, and can be examined in-depth on that basis - and I will ask others who are more familiar with this than either of us too about wild populations of several Varanus - for in your ideology, what works for one should/is applicable to the entire Genus, right? Is that what you think?
I did answer your question about Bernd's scenario and yours: READ BELOW: Yes I did write that, and see your name there after looking at it again - missed it the first time -
You discuss Bernd Eidenmullers enclosures at his home, and his many many successful breedings...as you have said yourself, breeding the varanids is easy, and it is, but incubation is hard. His enclosure was/is NOT a tiny aquarium, but a 400 gallon enclosure. Yes they have logs to sit atop and basking lights, and so do yours...so what is your point? You both have V. mertensi, you both breed them, and both your animals are healthy, so what is this point? I do not understand your question?? Do I think one is better than the other? You get the same results so where is the beef? Did I know of your specific husbandry techniques for your V. mertensi? No - I do not keep tract of such things anymore, as in the www, 'things' or truisms change from a day-to-day basis and I tire of keeping track of such things - again it is an issue of time, interest and priorities. I do this for fun, not business.
As for my preference for many things European, I do, but I like alot of things American too - and I did not state those, and that was (perhaps) an oversight. I too Love this Country, and enjoy being here with the many freedoms we have. I just want for USA what we can be, and not what we presently are...We can be and do better. I see alot of current dogma that has been seen before in History, and it has always been a disaster in the making for said Country, Gov't., and their peoples...and I do not want to see it happen here - do you? Of course not.
Furthermore, yes communication in the present is fine, but as I also said, "FOR POSTERITY AND FUTURE HERPERS" publishing it instills it into a format anyone anywhere, with the use of www can access anytime = what is wrong with wrong with that?? You can find any journal, almost any publication and get a copy of it within minutes, days, weeks perhaps but is in hard copy and can be reviewed at your liesure. Communication on these forums is fine, immediate (within a short time frame), and that is fine, but it does not hold up to time, the future, whence all of this forum materials is gone, passed over and lost. Yes, live for today the present, but writing it down lives for tomorrow and the next day....we just have oposing opinions of the same coin I think.

I will first address your comments of 'social behaviors' from below: Social behavior and its evolution there-of are derived the help an organism, any organism, from protozoan 'Volvox' - a semi-socially inclined single-cell cluster to higher mammals to live more successfully and pass on their genetic materials to generations there-of....however the 'conditions' under which social behavior permiates an organism and makes it solitary to gregarious, which you are stating have the following guide-lines (of which you may/may not agree with, but you need to understand these guidelines apply to all organisms equally):
(From Barlow & Silverberg, Ed., 1980:130-131 - and these guidlines have not wavered since then either)
1. restriction of suitable habitat or resources to a small number of spatial areas can lead to a passive accumilation of individuals in that area (= conditions of captivity).
2. Predator pressures: can promote either widely dispersed asocial living or dense gregarious coloniality (increase population density and inclination for gregarious behaviors).
3. pattern of dispersion is critical to prey selection. When food selection is thinly but equally dispersed so are the predators, and consequently the reverse also applies whereby if food is locally clumped and abundant, predators clump and are abundant (= komodo monitor feeding stations).
4. In dense groups of animals, the chances for build up and transmission of parasites/disease increases causing a more dispersed form of spatial organisation among the organisms = they 'spread out'.
5. The last condition favoring gregariousness is the importance of social information. Gregarious living allows observational learning and culture transmission of adaptive solutions to survival/prey selection/kin selection etc...Such conditions allow for rapid changes in behavior patterns, allowing them to adjust to short-term ecological changes and conditions.
One case in point, when a trio of V. niloticus (or solitary V.
griseus) go crocodile nest raiding as demonstrated by Cottom (1926), Carpenter (1923) one V. niloticus will look out for moma croc while other two excavate and prey on eggs, and they will rotate so all get a meal. Is this social or cooperative learning in prey selection?
For a species to be social, the 5 points listed above must be applied, and a 'degree' of sociality can be determined by the number of postulates agree with 'wild' observations. Captive conditions are articficial and cannot be applied to these postulate of social behavior as they only apply to points #1 and most importantly #5 is not exercised by varanids - which of course would be culture, and varanids do not do this. Many mammals do, even some birds.
Some of the postulates above could be used and are seen in captivity, but does that make the animals social on an innate/genetic level? No it does not - it is merely their ability to adapt to different conditions. V. griseus are basically solitary animals, but find the same female and the same nest in the same locality annually - but that does not make obligate social animals. No it does not.
What you see in your enclosures may be and can be misleading, unless it can be tested time and time again, methodically, and applied in this format, then you might have something there - but to see two animals arm over body, as I have seen this before when males guard females (ritualized combat -> reproduction behavior) does not mean they are social but merely protecting their gene pool between them from other males/nemesis/enemies.
Ethology (animal behavior) is not as clear cut as biology and chemistry, as those laws, rules, always are the same every time they are applied - a constant every time and do not change with time but as has been seen above with postulates #1-5, ethology is an explanation of adaptability of an organism to its environment, and is assessed under biological laws and rules in a very didactic forum.
Now for your second points on V. mertensi. Were you referring to the post reply I made to rsg about V. mertensi and V. acanthurus or something else? I did not mention your name anywhere else on this forum? You did make reference to me somewhere in association with Sam Sweet, and yes, I stick by his assessments, and yes we think alike about alot of things as we have a similar (although mine is not as advanced) academic training...and we enjoy varanids alot, and know alot about them, inside and out (vrs most herp keepers who only know the 'out').
I said in one of my posts, these german and dutch vara-keepers have been breeding their animals for decades, and backing it up with published literature accounts EUROPEEIDENMULLER, 1985, 1986, 1989, 1990, 1991a-b, 1992a-e, 1993a-b, 1994, 1995a-c, 1996, 1997a-b, 1998a-b; HORN, 1976, 1977a-b, 1978a-b, 1980, 1981a-b, 1982, 1985, 1986, 1988, 1989, 1991a-c, 1993, 1994a-b, 1995, 1997a-c; WESIAK, 1992, 1993a-c, 1998a-b.
North America: Arizona: -0- :1 paper mentions breedings, but no specific details. Now it is not always anyones inclination to publish what they do and nothing wrong with that what-so-ever, but the word of mouth changes with time (aka 'telephone game') and data misquoted, misconstrued and so on, so it has little worth or merit where posterity and time is concerned: the published record however, does! So even if you xerox your notes and sent them to me, I could and would put into a written format and help you get them published, as I have done with alot of people - no problem. then alot more people benefit from them and you do not have to repeat yourself as much as you do on these forums. The offer is there...I 'think' I do recall you saying anyone was invited to see your set up and so on, and you shared 1 V. acanthurus data with me which is in the files, but recinded your offer when we became nemesis/adversaries of opinions in varanid hsuabdry ideologies. No biggy there. I hate/cannot tolerate hot weather for more than a few hours anyway.
ok you breed animals, fine, no problem with that ever.... and you say you have thousands of offspring world-wide....how come I know -0- persons who have any of your offspring, ever? Ive been around the varanid circles for 20 years and never known an actual single person/herp keeper who has/had one of your offspring? I am not doubting your words, but pondering this mystery, but only a little, as my time is directed to other things varanid with more interest and enthusiasm.
I am delighted we can 'discuss' some things without the usual banter we direct towards one another - it is more pleasant. But are we really discussing, or just making opinions? Are we conversing here, being 'social' as it were, to our respective asocial tendencies (haha)?
And as preferring European ideologies, I am decended from Northern and Southern Europe going back 1000 years, and favor the temperament, educations, monarchy, and most laws there...but I do abhor the lousy weather and dark days of Scandinavia, so I live in Koo-koo California where its weather/climate is only matched by 40 miles on the Libyan coastline, and prefer not to dwell in the latter - I don't like dates or ginger beer.
