Two ants tested with either the steep or the shallow right-edge gradients aimed at a position 40 cm to the left of the edge for more than half the route, consistent with moving in a direction set by the initial memory of the right edge. Figure 6D shows the mean routes of one of these ants.
At each release site, peak route fidelity successfully predicted leadership in roughly three-quarters of paired releases: Greenhill Farm: 15 of 20, Weston Wood: 8 of 11; Church Hanborough: 3 of 4. Mean route fidelity predicted only 23 out of 35 cases, and initial route fidelity predicted 24 out of 35.
We then considered a number of measures of this distribution, characterizing each individual bird by either the mean route fidelity over the whole track, the peak route fidelity: the minimum 5percentnt of the variance (25 locations along the entire length of the mean route), or the initial route fidelity: the first 5 per cent of the variance (the first 25 locations along the mean route).
The mean exposure route of cyanide for adult and children increased according to the following order: ingestion > dermal contact.
We calculated individual ants' mean routes (normalized to the position of the landmark) by binning the ants' position in successive 5 cm bins along the line connecting the start and feeder.
Instead of using mean of route lengths we used ranks of route lengths.
(i Improved right-of-ways means routes which are of a permanent nature and would involve substantial alteration of the terrain or vegetation such as grading and graveling of surfaces or other such construction.
Parkour, a made-up word, cousin to the French parcours, which means "route," is a quasi commando system of leaps, vaults, rolls, and landings designed to help a person avoid or surmount whatever lies in his path — a vocabulary, that is, to be employed in finding one's way among obstacles.
The mean shortest or quickest route of the randomly sampled possible transmissions and non-transmissions are found and their difference calculated.
The relatively small sample size of neurones per group and per route of administration means that the mean can on occasion be shifted dramatically.
