[The transfer of information about the quantitative characteristics of an object in ants].

In the laboratory experiments devised on the basis of the Information Theory, ants (Formica polyctena Foerst.) had to transmit definite information on the number and coordinates of objects. One of the experimental sets consisted of a long "trunk" with branches ended in an empty trough, except for one filled with sugared water. Another set consisted of the lattice which simulated Cartesian coordinates. Ants had to learn position of the through and transmit its coordinate on the lattice. Obtained results suggest ants as being able to estimate the number of objects and transmit this information to their nest mates as well as the information on the coordinates of objects.
