TI  - What is the status of metabolic theory one century after Putter invented the von 
      Bertalanffy growth curve?

AB  - Metabolic theory aims to tackle ecological and evolutionary problems by 
      explicitly including physical principles of energy and mass exchange, thereby 
      increasing generality and deductive power. Individual growth models (IGMs) are 
      the fundamental basis of metabolic theory because they represent the 
      organisational level at which energy and mass exchange processes are most tightly 
      integrated and from which scaling patterns emerge. Unfortunately, IGMs remain a 
      topic of great confusion and controversy about the origins of the ideas, their 
      domain and breadth of application, their logical consistency and whether they can 
      sufficiently capture reality. It is now 100 years since the first theoretical 
      model of individual growth was put forward by Putter. His insights were deep, but 
      his model ended up being attributed to von Bertalanffy and his ideas largely 
      forgotten. Here I review Putter's ideas and trace their influence on existing 
      theoretical models for growth and other aspects of metabolism, including those of 
      von Bertalanffy, the Dynamic Energy Budget (DEB) theory, the Gill-Oxygen 
      Limitation Theory (GOLT) and the Ontogenetic Growth Model (OGM). I show that the 
      von Bertalanffy and GOLT models are minor modifications of Putter's original 
      model. I then synthesise, compare and critique the ideas of the two 
      most-developed theories, DEB theory and the OGM, in relation to Putter's original 
      ideas. I formulate the Putter, DEB and OGM models in the same structure and with 
      the same notation to illustrate the major similarities and differences among 
      them. I trace the confusion and controversy regarding these theories to the 
      notions of anabolism, catabolism, assimilation and maintenance, the connections 
      to respiration rate, and the number of parameters and state variables their 
      models require. The OGM model has significant inconsistencies that stem from the 
      interpretation of growth as the difference between anabolism and maintenance, and 
      these issues seriously challenge its ability to incorporate development, 
      reproduction and assimilation. The DEB theory is a direct extension of Putter's 
      ideas but with growth being the difference between assimilation and maintenance 
      rather than anabolism and catabolism. The DEB theory makes the dynamics of 
      Putter's 'nutritive material' explicit as well as extending the scheme to include 
      reproduction and development. I discuss how these three major theories for 
      individual growth have been used to explain 'macrometabolic' patterns including 
      the scaling of respiration, the temperature-size rule (first modelled by Putter), 
      and the connection to life history. Future research on the connections between 
      theory and data in these macrometabolic topics have the greatest potential to 
      advance the status of metabolic theory and its value for pure and applied 
      problems in ecology and evolution.
