doi:10.1038/s41598-017-17553-1: Variables extracted from radar tracks

1 x Excel file (.xls)

This file shows all
variable extracted from the radar flight tracks which were used in analyses for
the publication:

Woodgate JL, Makinson
JC, Lim KS, Reynolds AM, Chittka L. Continuous Radar Tracking Illustrates the
Development of Multi-destination Routes of Bumblebees. Scientific reports. 2017
Dec 11;7(1):17323. doi:10.1038/s41598-017-17553-1

The file contains one
row for each recorded flight. The following variables are included:

BeeID: unique number identifying
each individual bee we tracked. Numbers correspond to ‘Bee1’, ‘Bee 2’ etc in
the manuscript.

BoutNumber: number
identifying how many flights each bee had made. A single bout encompasses all
the activity made between the bee leaving the nest and returning again.

TrackingDay: keeps
track of whether each track was recorded on the first, second etc day on which
the bee was allowed to forage on the feeder array.

StartTime: Date and
time at which the bee left the nest for each foraging bout.

PathLengthTotal: cumulative length of a straight-line path between every positional
fix over the entire foraging bout.

PathLengthExplorationLegs:
each leg of the journey was characterised as an exploration leg, if the bee
travelled more than 50m from all previously discovered feeders or within-array
if it did not. This is the total distance travelled during exploration legs.

StraightLinePathLength:
the straight-line distance joining all the feeders
visited in each bout in the order they were visited; this is the shortest
distance a bee could travel while maintaining the observed visit sequence.

RatioStraightLineToObservedPathLength:
StraightLinePathLength / PathLengthTotal

DurationTotal: the total time elapsed between the bee’s departure from the nest and
its return.

SequenceOptimality:
referred to as optimality score in the manuscript. A measure of how similar the
sequence of feeder visits in each bout was to the visit order that leads to the
shortest possible flight path. See methods in the manuscript for further
details.

MeanLegStraightness: The straightness of each
leg of a track was defined as the distance component of the vector sum of the
straight lines connecting every pair of positional fixes within that leg and
can range from 0 (datapoints form a circle) to 1 (the path forms a straight
line). The straightness of an entire bout was the mean of the straightness
score for all legs; a score of 1 would indicate that the route was composed of
perfect straight lines between locations, although there may be changes of
direction from one leg to the next.

SequenceSelfSimilarity:
a measure of how similar the sequence of feeder visits in each bout was to the
sequence in the previous bout undertaken by the same bee. See methods in the manuscript
for further details.

FlightPathSelfSimilarity:
a measure of how similar the actual spatial positions of the bee during each
flight were to the previous flight undertaken by the same bee. See methods in
the manuscript for further details.

FlightPathMeanLegSelfSimilarity:
similar to FlightPathSelfSimilarity, but comparing each leg of the journey to
the most recent flight with the same starting and ending locations. See methods
in the manuscript for further details.
