Biol Rev Camb Philos Soc 82:113-42. 2007..We argue that the evolution of demand systems can only be understood in the light of that of supply systems. We illustrate some important points with data from the literature...
Scaling relationships based on partition coefficients and body sizes have similarities and interactionsS A L M Kooijman
Faculty Earth and Life Sciences, Vrije Universiteit, 1081 HV, Amsterdam, The Netherlands
SAR QSAR Environ Res 18:315-30. 2007..The strength of the theory is in the combination of why metabolic transformation depends both on the BCF and the body size. We illustrate the application of the theory with several data sets from the literature...
A new class of non-linear stochastic population models with mass conservationS A L M Kooijman

Math Biosci 210:378-94. 2007..For total nutrient values below the focus bifurcation point, the system gradually becomes more confined to the direct neighbourhood of the isocline for which the producers do not change...
What the egg can tell about its hen: embryonic development on the basis of dynamic energy budgetsS A L M Kooijman
Department of Theoretical Biology, Vrije Universiteit, De Boelelaan 1087, 1081 HV, Amsterdam, The Netherlands
J Math Biol 58:377-94. 2009..They can also decrease the egg size, however, such that the reproduction rate is stimulated at low concentrations. The present theory offers a possible explanation for this well-known phenomenon...

Department of Theoretical Biology, Vrije Universiteit, De Boelelaan 1087, 1081 HV Amsterdam, The Netherlands
Biol Rev Camb Philos Soc 83:533-52. 2008..We illustrate the methods using data on daphnids and molluscs...

Philos Trans R Soc Lond B Biol Sci 356:331-49. 2001..Strong and weak homeostasis and the partitionability of reserve kinetics are cornerstones of the theory and essential for understanding the evolution of metabolic organization...
Food chain dynamics in the chemostatM P Boer
Department of Theoretical Biology, Vrije Universiteit Amsterdam, The Netherlands
Math Biosci 150:43-62. 1998..It is shown that low as well as high concentration of input substrate can lead to extinction of the highest trophic level...
Consequences of population models for the dynamics of food chainsB W Kooi
Faculty of Biology, Free University, Amsterdam, The Netherlands
Math Biosci 153:99-124. 1998..Although the predicted transient dynamics of a food chain may depend sensitively on the underlying model for the populations, the global picture of the bifurcation diagram for the different models is about the same...

Faculty of Biology, Free University, Amsterdam, The Netherlands
Math Biosci 157:217-36. 1999..This may enable short food chains to be resistant to invaders. We will relate these results to ecological community assembly and the debate on the length of food chains in nature...
