Fig. 11. The simplified analytic model (SAM) fitted to data
(Müller and Wehner, 1988)
taken directly from figs 11ac in Hartmann and Wehner
(1995). The ants walked along
a channel from the nest, turned through an angle A, walked along a
second channel before being released on a test field. The lengths of the
channels were (A) 10 m and 5 m, (B) 5 m and 10 m and (C) 10 m and 10 m,
respectively.
shows the ants' homing direction (diamonds). In each
graph, the top line shows the SAM using a time constant of
=18.38; the
lower line shows the correct homing angle.
