Temporal patterns and multiple infections of avian haemosporidian parasites in great reed warblers (Acrocephalus arundinaceus)
The primary (acute) haemosporidian infection has the greatest negative effect on an individual’s fitness. Weak individuals are most likely eliminated from the population, while those that survive, develop a chronic infection when parasite infection intensity is kept at low levels with minor effects on the condition of the host’s life history traits. It is still unknown whether low levels of haemos
