Seasonal prevalence of the three common parasite egg morphotypes. Prevalences (probability of infection) shown for Subulura (a) dry season and (d) rainy season; Trichuris (b) dry and (e) rainy season; and Hymenolepis (c) dry and (f) rainy season in samples from gray mouse lemurs in Kirindy forest. Shown are all data points (with jitter introduced to the discrete variables for ease of interpretation) for males (solid symbol) and females (open symbol), and loess-smoothed prediction lines and 95 % confidence bands for age effects for males (dashed line) and females (solid line). Significant age effects (a and c, trajectories not significantly different for the sexes), and a significant age*sex interaction (f) shown with colored confidence bands, non-significant relationships with gray confidence bands.
