Stress protein levels and blood parasite infection in blue tits (Parus caeruleus): a medication field experiment
It has been suggested that blood parasites are a source of physiological stress for avian hosts in the wild. We report the first experimental evidence relating blood parasite infection to the physiological stress response in a wild avian population. We reduced through medication the intensity of infection by Haemoproteus majoris and the prevalence of infection by Leucocytozoon majoris in half o...
متن کاملSurvival costs of reproduction in the blue tit (Parus caeruleus): a role for blood parasites?
One of the central tenets in life-history theory is that there is a trade-off between current and future reproduction (i.e. a cost of reproduction). The mechanism for this cost of reproduction is, however, largely unknown. One hypothesis is that the high workload during reproduction compromises resistance to parasites and that the resulting increase in parasitaemia has negative effects on the p...
متن کاملBreeding performance of blue tits (Cyanistes caeruleus) and great tits (Parus major) in a heavy metal polluted area.
We compared heavy metal levels, calcium levels, breeding parameters and condition of nestling and adult Cyanistes caeruleus and Parus major along a heavy metal pollution gradient. Both species started laying earlier and showed inferior nestling growth and smaller fledging probability in the polluted areas, which are phenologically advanced in spring due to sparse forests. The major inter-specif...
متن کاملWithin-population variation in prevalence and lineage distribution of avian malaria in blue tits, Cyanistes caeruleus.
The development of molecular genetic screening techniques for avian blood parasites has revealed many novel aspects of their ecology, including greatly elevated diversity and complex host-parasite relationships. Many previous studies of malaria in birds have treated single study populations as spatially homogeneous with respect to the likelihood of transmission of malaria to hosts, and we have ...
متن کاملHigh Prevalence and Lineage Diversity of Avian Malaria in Wild Populations of Great Tits (Parus major) and Mosquitoes (Culex pipiens)
Avian malaria studies have taken a prominent place in different aspects of evolutionary ecology. Despite a recent interest in the role of vectors within the complex interaction system of the malaria parasite, they have largely been ignored in most epidemiological studies. Epidemiology of the disease is however strongly related to the vector's ecology and behaviour, and there is a need for basic...
