“…They do not make the common assumption that isotope dynamics is at equilibrium, and include the full metabolism in their analysis. Troost et al (2010) adjust DEB individual models for cockles and mussels to a specific site by adjusting the functional response. With this model they detected food preferences in cockles and mussels, inferring the importance of detritus and intraspecific competition under field situations.…”

We present the state of the art of the development of dynamic energy budget theory, and its expected developments in the near future within the molecular, physiological and ecological domains. The degree of formalization in the set-up of the theory, with its roots in chemistry, physics, thermodynamics, evolution and the consistent application of Occam's razor, is discussed. We place the various contributions in the theme issue within this theoretical setting, and sketch the scope of actual and potential applications.Keywords: dynamic energy budget theory; biology; metabolism; ecology; evolution; energetics REACHING OUT FOR GENERALITYIn physics, there is a quest for a unified theory. Physical theories have a broad spectrum of application, a strong mathematical background and are subject to numerous empirical tests. By contrast, in biology, mathematical theory has played a secondary role because biology is frequently seen as a science of exceptions and particular cases, with little interest in abstraction and generalization. Exceptions are the research being done in the fields of theoretical biology and mathematical biology. However, theoretical and mathematical biology have frequently been carried out without a concern for empirical testing. When this concern appears, models are of narrow application, reducing their theoretical breadth. The dynamic energy budget (DEB) theory starts from the Dutch tradition of theoretical and mathematical biology, but couples it with a fundamental concern in producing general theory that is subjected to careful empirical testing.DEB theory aims to capture the quantitative aspects of metabolism at the individual level for organisms of all species. It builds on the premise that the mechanisms that are responsible for the organization of metabolism are not species-specific (Kooijman 2001(Kooijman , 2010. This hope for generality is supported by (i) the universality of physics and evolution and (ii) the existence of widespread biological empirical patterns among organisms . Table 1 synthesizes the essential criteria for any general model for the metabolism of individuals. We explore the links between DEB theory and each of the proposed criteria in the following paragraphs. DEB theory is explicitly based on the conservation of mass, isotopes, energy and time, including the inherent degradation of energy associated with all processes. So it complies to criteria 1, table 1.The DEB theory is biologically implicit, so it applies to all species. Species-specific restrictions of DEB models are explained and predicted by the theory (criterion 5, table 1). For example, consider the most important difference between DEB models, the number of reserves (biomass components that fuel metabolism) and structures (biomass components that have maintenance needs) that are delineated. This depends on the degree of coupling of the various substrates an organism needs. Animals feed on other organisms, which couples uptake of the various substrates (proteins, carbohydrates, lipids, nutrients) tightly and ex...

“…This Oosterschelde estuary is a shallow, macrotidal and mesotrophic estuary with large stocks of mussels, oysters, and cockles ( Fig. 1A and B; Troost et al, 2010;van Broekhoven et al, 2014). Because of potential contamination of these shellfish with phytoplankton toxins, The Netherlands has a regular monitoring program for toxic compounds in shellfish, as well as for the occurrence of harmful algal species in the Oosterschelde estuary (van der Fels-Klerx et al, 2011).…”

“…The Dynamic Energy Budget (DEB) theory, proposed by Kooijman (1986) and extensively discussed by Kooijman (2000Kooijman ( , 2010, is based on a more mechanistic view and has already been successfully applied to model bivalve dynamics (e.g. Ross & Nisbet 1990, van Haren & Kooijman 1993, Bacher & Gangnery 2006, Pouvreau et al 2006, Troost et al 2010). The DEB the-ory is conceptually different from the net-production models approach, because it assumes that all assimilated energy is first stored as reserve (which does not require maintenance); subsequently, the reserve is utilized to fuel other metabolic processes such as maintenance, growth, development and reproduction.…”

A model for bivalve growth was developed and the results were tested against field observations. The model is based on the Dynamic Energy Budget (DEB) theory and includes an extension of the standard DEB model to cope with changing food quantity and quality. At 4 different locations in the North Sea (Wadden Sea, Sean Gas Field, Oyster Grounds and Dogger Bank), labelled blue mussels Mytilus edulis were kept under natural conditions. Shell length was repeatedly measured for each mussel during the experiment, and dry weight was determined at the end of the experiment for some of the mussels. Temperature, salinity, chlorophyll concentration and Secchi depth (at the Wadden Sea location) were measured next to the experimental sites. Model performance was evaluated by comparing predicted and measured shell length, dry weight and growth at each location for each individual, without changing parameter values that were previously obtained from independent studies. The results show that the model was able to reproduce the main patterns of the observations, implying that the main metabolic processes at the individual level are well described.

In addition, DEB models do not use empirical allometric relationships but simply state that food uptake is proportional to the surface area of the body, whereas maintenance scales mainly to structural body volume. One of the main advantages of a DEB model is that it is based on a generic theory, meaning that the same model structure can be applied to different species, where only parameter values differ. Variability in growth and reproduction between individuals of the same species are assumed to be mainly caused by differences in environmental conditions (temperature, food). Interspecific variability (among several species) is caused both by differences in parameter values as well as environmental conditions (Kooijman 2000(Kooijman , 2010. Here we aimed to test to what extent a generic model for an individual mussel is realistic enough to be used for population modelling in the future. The obtained model results were compared with real observations on the growth of the blue mussel Mytilus edulis at 4 different locations in the North Sea, with 1 station in a coastal environment and 3 stations in the open sea (off shore). MATERIALS AND METHODS DEB modelThe standard DEB model, described by Kooijman (2010), was adapted and extended using the feeding processes model proposed by Saraiva et al. (2011b). The basic assumptions of the DEB model are:(1) an or...
