I too saw the show. Very nice job. i was particularly impressed with the implementation of the low-tech tracking system and the inclusion of the other study groups. The degree to which the lizards avoided contact was amazing, with entire groups relocating once disturbed. Does this occur with any other species? This means of communication is quite intrigueing. could there be whole sets of signals or other messages that can be transmitted via such methods? Does this qualify as basic culture, in that the lizards are communicating somewhat abstract concepts between one another? Are there any individuals doing similar work with v. rudicollis? Just had to ask.... Guy
