Avian malaria is a worldwide mosquito‐borne disease caused by Plasmodium parasites.
These parasites occur in many avian species but primarily affect passerine birds that have …

Abstract Fifty years ago David Lack put forward a key hypothesis in life-history theory: that
avian clutch is ultimately determined by the number of young that parents can provide with …

It has become increasingly clear that life‐history patterns among the vertebrates have been
shaped by the plethora and variety of immunological risks associated with parasitic faunas …

There has been considerable recent interest in the effects of life-history decisions on
immunocompetence in birds. If immunocompetence is limited by available resources, then …

Malarial parasites are supposed to have strong negative fitness consequences for their
hosts, but relatively little evidence supports this claim due to the difficulty of experimentally …

If a trade–off exists between reproductive effort and immune function, life–history decisions
may have important implications for parasite resistance. Here, we report effects of …

The costs of egg production and incubation may have a crucial effect on avian reproductive
decisions, such as clutch size and the timing of reproduction. We carried out a brood–size …

Egg quality is a phenotype of, and can profoundly influence fitness in, both mother and
offspring. However, the physiological mechanisms that underlie this maternal effect are …

Given the intimate association in host–parasite systems, parasites are expected to initiate
their own reproduction when vulnerable hosts become abundant and/or when adult hosts …

Malaria parasites are a major cause of human mortality in tropical countries and a potential
threat for wildlife, as witnessed by the malaria‐induced extinction of naive Hawaiian …
