Ecotoxicological Applications of Dynamic Energy Budget Theory

Energy homeostasis as an integrative tool for assessing limits of environmental stress tolerance in aquatic invertebrates

“…These models are extremely useful in predicting the ecological and populationlevel consequences of bioenergetic shifts. However, they require extensive parameterization that is time-and effort-consuming and feasible only for a few well-studied species (Van Haren and Kooijman, 1993;van Haren et al, 1994;Bacher and Gangnery, 2006;Kooijman et al, 2009;Sarà et al, 2012). Given enhanced anthropogenic pressure on wild populations, it becomes increasingly important to identify approaches to rapidly assess the degree of stress experienced by the population, to integrate the effects of multiple stressors and predict its likely outcome for the population persistence.…”

“…An important common theme emerging from these studies points towards energy balance as a key factor that determines stress tolerance limits of an organism and can directly translate into population-and ecosystem-level consequences. Recently, quantitative bioenergetic models [such as the family of the dynamic energy budget (DEB) models proposed by Kooijman (Kooijman, 2010)] have been used to link whole-organism bioenergetics to population growth in a variety of organisms and to incorporate environmental forcing variables such as toxins, food availability and temperature stress (van Haren et al, 1994;Pouvreau et al, 2006;Kooijman et al, 2009;Einarsson et al, 2011). These models are extremely useful in predicting the ecological and populationlevel consequences of bioenergetic shifts.…”

Mercury tissue residue approach in Chironomus riparius: Involvement of toxicokinetics and comparison of subcellular fractionation methods

“…This may be interpreted as the result of a toxic effect of Hg bound-HSP affecting, for instance, lipid peroxidation (Arambourou et al, 2013) or protein functioning and synthesis (Barka et al, 2001). However, regarding the intense Hg trafficking at the subcellular level, this growth impairment could also be attributed, referring to the DEBtox theory (Kooijman et al, 2009), to a change in the energetic allocation between somatic maintenance (excretion and/or detoxification processes) and growth. Although quite moderate, this impact on growth could be particularly important for insects with short adult stages, because fecundity is determined by the size of larva (especially female) upon metamorphosis (Péry et al, 2002).…”

Impact of engineered zinc oxide nanoparticles on the energy budgets of Mytilus galloprovincialis

“…DEB theory uses three modeling modules to describe the toxic effects of pollutants on individual organisms (Billoir et al, 2008;Jager and Zimmer, 2012;Kooijman and Bedaux, 1996a,b;Kooijman et al, 2008). The first is a Dynamic Energy Budget (DEB) model that describes the rates at which organisms acquire resources from the environment and use the energy and nutrients therein for growth, maintenance and reproduction (Kooijman, 2010;Nisbet et al, 2000;Sousa et al, 2008).…”
