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

   Author : Ineke T. van der Veen; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; Developmental biology; 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

4. 2. Food and Parasites – Life-history Decisions in Copepods

   Abstract : In the freshwater copepod, Macrocyclops albidus, food availability, rearing conditions and tapeworm infection clearly affected various life-history traits and their trade-offs. I found that low food availability clearly constrained resource allocations to several life-history (often phenotypically plastic) traits, whereas high food availability either allowed for adjustments in resource allocation patterns or allowed resources to be allocated to several traits without apparent trade-offs.
