Counting ants

1. The authors do not provide a single complete video of the experiment, only very short 5-15 seconds fragments.
2. The papers lack detailed experimental procedures and protocol description (compared to a typical paper from Nature on the same subject).
3. The papers are published in seemingly unrelated journals, which may not have the adequate know-how to do peer review of such experiments: Electronic Transactions on Artificial Intelligence, IEEE Information Theory Society Newsletter, etc. If the behavior described is real, it is highly notable, I would expect at least one paper published in Nature by the authors.
4. The only videos available are short fragments, where 1 ant is seen crossing a single (1) left/right branch. Why not film an entire ant path, which according to paper should last about 100-200 seconds?

I also checked both author's pages: http://boris.ryabko.net/papers.html http://reznikova.net/Publications.html
Is this specific counting and communication capability independently confirmed by other research groups?
I was disappointed to read this, I tried to figure out in my head how they count ants in the world, and now I'm left with that void...
Edit: After having read the article, I'm not disappointed anymore, this was really interesting!
1. Collect 25 ants
2. Paint a dot on their abdomens
3. Release them
4. Wait
5. Collect 25 ants again
6. Count how many are marked with dots
7. Divide 25² by this number
The result is a pretty good approximation of the size of the total ant population. To increase precision and accuracy, replace all the "25"s above with a larger number.
