Karl:

Have received your paper on Heloderma combat.  Am preparing a 
parallel with specimens from my colony of Varanus salvator cumingi.  
Striking similarities!  First evidence and report of such behavior 
was complied by Hans Georg Horn of Germany.  But it was a spontaneous 
occurence.  I am running my colony through several controlled 
experiments.  Male to male, male to female, female to female, adult 
vs. yearling, sibling rivalry, etc.  I just moved the colony outside 
to a very large enclosure and need a week or two for them to 
acclimate to the outdoors again.  They get downright vicious after 
being in the real sun for a few days. But this is good. We want them 
to retain their aggressive behavior towards humans.  They will be 
sent down to the facility in Costa Rica by next summer and then we 
can begin the real work.  Mindanao has repeatedly ignored the problem 
of wild harvested animals so our colony will be the largest, outside 
of Mindanao wild pops,  for re-introduction.  I am working with the 
USFWS to acquire some V.s.nuchalis and V.s.marmoratus.  Also, the Ft. 
Worth zoo has those V.olivaceous that I want to work with.  They 
tried to breed them several years ago but without success. They don't 
realize how important diet simulation is: they keep feeding them 
rodents!  I am working with the Botanical Research Institute of 
Texas, Philippine PLant Identification Program - part of the 
international Flora Melasiana project - to build lists of regional 
endemic flora to the Phil archipelago.  They are going to give me 
several known fruit trees that olivaceous prefers. I think they will 
do well here in Houston.  Now if we can just get the lizards! 

Of mention, have talked with Taylor in Australia and he is sending me 
a paper on V.varius [sp.].  He has compiled various field data 
concerning parental roles within the V.varius complex.  I think this 
course of research is most important.  I do agree with you - given 
the limited ability for neonate Heloderma to capture moving prey, it 
would seem likely that the adults provide assistance.  Varius, after 
an incubation time of almost 10 months, returned to the mounds to 
help the neonates emerge from the crusty outer layer.  The new info 
will explain if the returning animal is the male or female, the 
actual mother, how long the animal waited before excavating the nest 
and how much assistance she provides after emergence. Unlike 
Heloderma, the neonate varanids are able to hunt immediately. 
However, their striking colors, unlike V.komodoensis, do not match 
the landscape so we wonder if the "mother" actually protects them. It 
has not been reported whether young varius have been encountered in 
close proximity to the "mother".  I need to go over there.  Steve 
Irwin invited me to stay at the Queensland Reptile and Fauna park but 
the best time would be near x-mas when the eggs start hatching.  I 
need some funds!!!  

I also have several behavioral reports on the Odatria sub genera 
regarding combat and mating rituals. You will find it extremely 
interesting so I will let you be surpised.  

Have spoken with the US Fish & Wildlife agents re Operation Chameleon 
confiscations.  They said that after the convictions, they are most 
likely going to place the 5 undescribed specimens with my facility.  
That is great news - I just hope it happens quickly as we need that 
female.  He told me that several "exploiters" are trying to get them 
but he said there is no way he is going to let anyone have them that 
is not involved with conservation breeding projects.  I expect that 
after the "collectors" find out I have the 5 lizards, I will start 
getting phone calls offering large amounts of money.  So, needless to 
say, don't tell anyone that I am poised to obtain them.   Pepin at 
Wash. U is going to sequence some tissue so that may help 
in establishing origin.  The CITES papers said Malaysia but they came 
from Anson Wong so that explains the COO.  My guess, based on 
morphological attributes and resemblance to V.s.cumingi, is that they 
are of Sulawesian origin. Or perhaps Molucca I.  But without getting 
my hands on them....I need to do some scale counts and examine their 
hemipenes.  That shouldn't be too hard - if they are anything like 
cumingi, they will not hesitate to defecate all over me!!  

You need to call the curator at the Columbus Zoo for that 
V.s.komaini. It is a guaranteed female and we need her.  The Germans 
at Frankfurt have a trio of males.  After we get a clutch from her, I 
want to send the progeny to Frankfurt and have them surplus me 2 
males.  Also, did you get the Helos set up for this year?  We need at 
least 4 to send to that guy with the other V.s.komaini. It appears to 
be of the same locality.  And a few for the additional V.s.cumingi 
from Frankfurt.  They want one of my males but I said not until I get 
a clutch.   

Anyway, I am sending the package snail mail so you should be getting 
it in a day or two.  I am looking into DVD applications for the 
research results.  We could put video on a CD but storage capability 
is about 650MB. That is not much for video.  The DVD will hold 
approx. 7 GB and maybe more.  This would be a perfect media to use as 
we could put video, bibs, ecological data, relevent papers, maps, etc 
all on one disk with excellent navigational menus. But, the licensing 
for DVD is WAY out of our financial capabilities.  It is too new 
still.  It will happen.  It is not mainstream yet.

Anyway, I'll talk with you after you get back from Alpine. Say hi to 
Queen.  You need to buy that panhead from him. Then we can both ride 
57s!  His does have the stock rigid frame I hope!  Trade him some 
rallyii! Keep your eyes out for 50s suburbans for me.  Remember, the 
suburbans have windows, the panels do not.   Yours, E
