From: Flexible parental care: Uniparental incubation in biparentally incubating shorebirds
Daily nest attendance in biparental and uniparental shorebirds. (a) Distribution of biparental and uniparental daily nest attendance. Box plots depict median (vertical thick line inside the box), the 25th and 75th percentiles (box), the 25th and 75th percentiles ± 1.5 times the interquartile range or the minimum/maximum value, whichever is smaller (bars), and the outliers (dots). (b) Change in daily nest attendance across the incubation period (expressed as the proportion of the species’ typical incubation period). Each dot represents the nest attendance during one day. (c,d) Change in hourly nest attendance across the day. Circles (c) represent mean hourly observations for each species (circle size reflects sample size). (b,d) Lines with shaded areas indicate model predictions with 95% confidence intervals (Supplementary Table 2 & 4 in ref.27) based on the joint posterior distribution of 5,000 simulated values generated by the ‘sim’ function in R41. (a–d) Only nests that contain a uniparental incubation phase are included. Green (
) indicates biparental species during a biparental phase, blue-grey (
) biparental species during a uniparental phase, and yellow (
) uniparental species. N
a-b = 895 days and N
c-d = 23,258 hours from 87 nests of 10 species (65 nests of 8 biparental species, 22 nests of 2 uniparental species).
