Abstract
This thesis investigates effects of short-term food shortage on growth, body composition and metabolic development of Pekin ducklings (Anas platyrhynchos domesticus) and European shag nestlings (Phalacrocorax aristotelis), two species representing extremes within the altricial-precocial spectrum. The aims of the thesis were to 1) characterise patterns of growth and development in response to short-term food shortage during early development, 2) examine aspects of energy allocation during these responses with special emphasis on the basal level of energy metabolism, thermoregulatory ability and body composition and 3) investigate the effect of shortterm food shortage on subsequent growth and fledging body size.
