Table 3.

Formal summary of the results shown in Tables 1 and 2.

				Dark vs. light			With lights on			With lights off
Level of activity	Distance traveled and speed			Longer distances			Increase with stone density			Remains high
Temporal structure	# of stops and trips			More stops and trips			More stones = more stops and trips
	Trip length			Shorter trips			More stones = sorter trips
	Stops/trip			Fewer stops/trip			Did not change			Decreased
Spatial distribution	Path shape			Winding (zigzag) paths			More stones = straighter path
	Time and stops at the perimeter			More time and stops in center			More stones = more time and stops in center
