Capturing continuous, long timescale behavioral changes in Drosophila melanogaster postural data
Fig 2
Principal component analysis of stereotyped behavioral components of all flies across all experimental hours. A Biplot showing the projections of individual fly hours and loadings of the centered log-ratio of each stereotyped behavioral component. Dark gray dots show time points from when lights are off and light gray dots show time points when lights are on. B Mean projection of PC1 against time of day for all complete 24h periods of all flies. The shaded region is the standard error. C Mean Day/Night difference vs day of experiment as measured by the absolute value the average projection onto PC1 during night hours minus the projection onto PC1 during day hours. The shaded region is the standard error. D Mean projection of PC2 against time of day for all complete 24h periods of all flies. The shaded region is the standard error.
