Abstract

Brood size manipulation has long been used as a way to determine the effect of altered parental effort on the quality of chicks produced and the consequences for the parents, one of these consequences being survival. The resource allocation theory suggests that increased parental effort, or rather reproductive effort comes at a cost of reduced self-maintenance, which is turn negatively affects senescence and survival. In this thesis, the variation in effect of enlarged brood size on parental survival is analyzed to determine which parameters influence this effect. The results show that longevity has a strong negative effect on the correlation between enlarged brood size and parental survival, meaning that long-lived bird species are more severely negatively affected than short-lived species. The results also show an interaction between longevity and the logarithm of the body mass, where high body mass counteracts the effect of longevity. The significance of this interaction is however questionable.
