| Abstract |
|
Over the past 12 years, we have been passively observing gopher tortoise, Gopherus polyphemus behavior, as well as certain behaviors in a number of species of tortoises including several species of Testudo, Pyxis, Geochelone and one emydid. Many observed behaviors have raised an important the question. Are chelonians communicating beyond the tactile, visual and limited sounds we ca, hear? In the summer of 2004, we convinced NSF to support a group of animal communications experts with technical guidance and training, providing equipment to set up a series of experiments to determine if we were correct. In fact, in the short time we had to work out methods and equipment problems, we were able to record low frequency sound communications, below 40 Hz in a number of species. Most exciting was the complicated communications between gopher tortoises while they were in the bottom of their burrows. We are now are collecting low frequency communications while observing specific behaviors like aggression between two G. sulcata males. We intend to begin a process of recording a sound profile on all chelonians for storage in a sound reference library as is done with birds.
