2 Contents Introduction Waste – to – hurry Allocation to soma Supply-demand spectra 2004/04/18 SETAC workshop, Praha: Relating impacts on life history aspects to Energy Budget Models

3 Dynamic Energy Budget Dynamic: Full life cycle: embryo, juvenile, adult Energy: Feeding Digestion Storing Growth Maturation Maintenance Reproduction Product formation Aging Budget: Conservation: energy, mass, time

4 Waste to hurry a Exploiting blooming resources requires blooming yourself high numerical response short life cycle small body size fast reproduction fast growth high feeding rate resting stages between blooms  -rule explains why [p M ] needs to be high Ecosystem significance: flux through basis food pyramid Kooijman 2013 Oikos 122:
