Population Biology of Passerine Birds is an up-to-date synthesis of the most recent developments in its field, especially in the framework of modern life history theories. Major topics include quantitative genetics, ecological physiology, the study of social structures using individually marked birds in the wild, and finally biometry, which allows to quantify such important parameters as survival at different stages of life and to create a model of the overall demography of the populations.Proceedings of the NATO Advanced Research Workshop on Demographical, Physiological, Behavioural and Genetical Aspects of Population Biology of Passerine Birds held at Evisa, Corsica, France October 3-8, 1989Population Biology of Passerine Birds is an up-to-date synthesis of the most recent developments in its field, especially in the framework of modern life history theories.
