Figure 1From: Explaining variance of avian malaria infection in the wild: the importance of host density, habitat, individual life-history and oxidative stressPlasmodium infection in relation to breeding density and age. Infection of a ) P. relictum, and b ) P. circumflexum in adult great tits (first year breeders and older) in relation to experimental manipulation of breeding density (LD = low density, HD = high density). Mean ± Confidence Intervals (CI), presence = 1 and absence = 0, i.e., the higher value the larger proportion is infected.Back to article page
