Fig. 2From: Spatially different annual cycles but similar haemosporidian infections in distant populations of collared sand martinsSite specific total prevalence (upper panel) and frequency of total parasitaemia of haemosporidian infections (lower panel) of collared sand martins (Riparia riparia) in northern-central and eastern-central Europe breeding in coastal and inland Germany and Hungary, and during migration in south-eastern Europe when passaging Greece. Parasitaemia, i.e., the strength of infection, represents the percentage of infected erythrocytes per sampleBack to article page
