Comparison of trail networks used and available in the surrounding vegetation.

Values for ‘Available’ are for the entire mapped vegetation network, including the nodes and edges that were observed to be used by the ants. Values for ‘Used’ are means ± S.D., averaged over n observation days, for the paths observed to be taken by the ants i (n = 10 for Tejon 189 and Turtle Hill 460, n = 5 for Tejon 500, and n = 11 for Tejon 446). Connectivity is a measure of the smallest number of nodes needed to get back to the trail used by the ants from an edge off the trail, averaged over all edges that lead off the trail used by the ants (Methods).
