Figure 4  Boxplots showing differences in body mass (g) and body size (pronotum length, mm) between the sexes and levels of diet quality in Gryllus texensis for the Kelly and Tawes (2013) data. The box represents the lower (25%) and upper (75%) quartiles, the solid dark horizontal line is the median, and the whiskers indicate 1.5 times the interquartile range. Data beyond the end of the whiskers are outliers and plotted as black dots (females, n  = 82; males, n  = 92; high-quality diet, n  = 99; low-quality diet, n  = 75). P -values are from one-way ANOVAs testing for differences in mass or size between each treatment level (see text).
