Daily temperature profiles (A) for a representative individual from the cyclic female (blue), acyclic female (teal), and acyclic male (red) categories. Temperatures when asleep (darker shades) show higher distal body temperature with a smaller range than when awake. Violin plot of mean temperature by category (B) and variance (C) across all 24 h (left), only wake times (center), and only sleep times (right). Violin plot of nightly maximum temperature (D) for females subset by age bin, split by cyclic status, with quantiles in white. Kernel density estimate for average temperature by category during wake (E) and sleep (G). Kernel density estimate for temperature variance by category during wake (F) and sleep (H). Bonferroni corrected p-value annotations for 9 comparisons: *: 1.00e−3 < p <  = 6.00e−3, **: 1.00e−4 < p, ***: 1.00e−5 < p, ****: p <  = 1.00e−5
