Migrations, ie the recurring, roundtrip movement of animals between distant and distinct
habitats, occur among diverse metazoan taxa. Although traditionally linked to avoidance of …

Migratory animals are widely assumed to play an important role in the long‐distance
dispersal of parasites, and are frequently implicated in the global spread of zoonotic …

Theoretical studies predict that parasitic infection may impact host longevity and ultimately
modify the trade-off between reproduction and survival. Indeed, a host may adjust its energy …

Aim The role of migratory birds in the spread of parasites is poorly known, in part because
migratory strategies and behaviours potentially affecting transmission are not easy to study …

During their journeys, migratory birds encounter a wider range of parasites than residents,
transporting them over vast distances. While some parasites are widely distributed …

In migratory passerines, the prevalence and parasitaemia of blood parasites often increase
towards the end of the breeding season. Consequently, post-breeding migration to winter …

Avian malaria parasites can negatively affect many aspects of the life of the passerines.
Though these parasites may strongly affect the health and thus migration patterns of the …

Corticosterone (CORT) is the main glucocorticoid hormone of amphibians, reptiles, birds
and some mammals. This hormone may have evolved as an adaptive metabolic …

Waterfowl managers lack information regarding factors that may be reducing the positive
response of waterfowl body condition to habitat improvements. Protozoan blood parasites …

Migratory birds are important carriers of pathogens such as viruses, bacteria and protozoa.
Avian haemosporidia have been detected from many wild birds of Japan, but the infection …
