House Sparrow (Passer domesticus) Science Article 7 abstract In this study we relate variation in lifetime reproductive success (LRS) of male and female house sparrows Passer domesticus to morphological characteristics. Our analyses demonstrated no sex-specific difference in the distribution of LRS. The variance in LRS was influenced mainly by variation in individual annual reproductive success, […]

House Sparrow (Passer domesticus) Science Article 1 abstract The activation of an immune response is beneficial for organisms but may also have costs that affect fitness. Documented immune costs include those associated with acquisition of special nutrients, as well as immunopathology or autoimmunity. Here, we test whether an experimental induction of the immune system with […]

House Sparrow (Passer domesticus) Science Article 2 abstract […]. The aim of this study is to determine whether House Sparrows from a Spanish population are indeterminate or determinate layers for removal and addition experiments. Because methodology used in this sort of studies appears to affect results, the same methodology was used as that of Kendra […]

House Sparrow (Passer domesticus) Science Article 6 abstract The house sparrow Passer domesticus is unique among wild birds in its close association with, indeed virtual dependence on, man.
