Movement patterns and activity of desert-adapted lions in Namibia - March 2009

> Activity Patterns

Data from five GPS collars, where the sampling frequency was >1 fix/hour, were included to assess patterns of activity. Distances moved per hour were used as an index of activity. To control for individual biases (e.g. mean distances moved by different lions per night) the distance moved per hour was expressed as a proportion of the total distance moved by the lion on that night. The patterns of activity are remarkably similar for all five lions (Figure 2). A sharp peak of activity occurred from between sunset and 20h00, followed by a drop in activity between 21h00 and 22h00. Activity increased again around midnight, but thereafter the pattern became less uniform although activity decreased towards daybreak, especially amongst the females. After sunrise activity increased and peaked between 07h00 and 08h00, followed by a uniformly sharp decline, and by 11h00 all five lions had stopped moving.
