From: Seasonal variation in daily activity patterns of snow leopards and their prey
The relative proportion of snow leopard activity across the 24-h cycle for adult males and females during winter (blue) and summer (red) for two types of activity data collected from the GPS-collars (a = GPS movement data; b = accelerometer activity data). The activity densities on the y-axis have no absolute meaning, but rather are relative measures of probability density calculated from the raw movement data. The time of all observations has been standardised along the x-axis using ‘sun-times’; where the time of observation on each day is calibrated to sunrise, solar-noon (midday) and sunset. These overlap plots show the activity overlap between winter and summer activity (grey) and highlight periods when activity was greater in winter or summer (blue or red shaded polygons, respectively).
