  1. 1. Trade-off between starvation and predation : Weight-watching in Yellowhammers

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ineke T. van der Veen; Uppsala universitet.; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi Utvecklingsbiologi; populationsbiologi; Population Biology;

    Abstract : In this thesis I show that captive yellowhammers (Emberiza citrinella) strategically adjusted their level of body mass and diurnal trajectory of mass increase to experimentally increased predation risk. During winter, small birds need large fat reserves to survive the night. Therefore, they build up fat reserves every day. READ MORE
