High costs of infection: Alphavirus infection reduces digestive function and bone and feather growth in nestling house sparrows (Passer domesticus)
Fig 2
Daily measures of (A) body mass, (B) head-beak and (C) tarsus lengths during infection (mean ± SEM). Nestlings were age 7 days post-hatch when infected (0 DPI). n = 11 at 0-2DPI; n = 7–8 at 3DPI, n = 4–5 at 4 DPI. Asterisks above bars indicate significant difference between treatment groups by two-sample t-test (4 DPI was not analyzed due to low sample size).
