Using conditional circular kernel density functions to test hypotheses on animal circadian activity

► We describe conditional circular kernels to test hypotheses in animal activity. ► The models allow control of the smoothing parameter and density isopleth. ► We apply our models to camera-trap data on large mammals from the Pantanal. ► The models adequately describe the timing of main activity pea...

Description
Summary:► We describe conditional circular kernels to test hypotheses in animal activity. ► The models allow control of the smoothing parameter and density isopleth. ► We apply our models to camera-trap data on large mammals from the Pantanal. ► The models adequately describe the timing of main activity peaks. ► Activity range and activity overlap prove useful in comparing the species.
