Our goal was to understand and characterize the difference between these two modes of navigation, namely off-trail versus on-trail navigation, employed by seed harvester ants [34].
Updating and using the pheromone trail for navigation is part of the ants' collaborative capabilities.
Design a row of links called navigation trail or breadcrumb trail on your pages either at the top, bottom, or both.

On a recent cross-country trip he opted to use his iPad for trail and road navigation instead of a $300 handheld GPS device.
£35 for one day or £75 for two, 27 and 28 April, foe.co.uk This race through Borrowdale and up Scafell Pike is for experienced runners – the trails are tough; navigation skills are needed for unmarked sections; and anyone failing to run the first 17km quickly enough will not be allowed up the mountain.
While some ant species supplement their weak eyesight with pheromone trails to aid navigation, others use their pinhead-sized brains to analyze their surroundings and blaze their own path.
The guide is needed not so much for navigation (the trail is very well marked and, in any case, is one straight line) as to point out and identify the indigenous wildlife, which includes some 280 species of bird.
Strong demand at the start of the season for a handful of must-have electronics, like digital frames and portable GPS navigation systems trailed off in December.
Moreover, one should keep in mind that two dynamics of the human trail system formation and human navigation in the environment are closely interrelated.
