* [https://www.bio.vu.nl/thb/deb/deblab/add_my_pet/index.html Add my pet (AmP)] project is a collection of DEB models for over 1000 species, and explores patterns in parameter values across taxa.  Routines for parameter exploration are available in [https://www.bio.vu.nl/thb/deb/deblab/add_my_pet/AmPtool.html AmPtool] .
* Models based on DEB theory can be linked to more traditional bioenergetic models without deviating from the underlying assumptions. This allows comparison and testing of model performance . 
* A DEB-module (physiological model based on DEB theory) was successfully applied to reconstruct and predict physiological responses of individuals under environmental constraints  
* A DEB-module is also featured in the eco-toxicological mechanistic models ([http://www.debtox.info/software.html DEBtox implementation]) for modeling the sublethal effects of toxicants (e.g., change in reproduction or growth rate)   
* Generality of the approach and applicability of the same mathematical framework to organisms of different species and life stages enables inter- and intra-species comparisons on the basis of parameter values, and theoretical/empirical exploration of patterns in parameter values in the evolutionary context, focusing for example on development, energy utilization in a specific environment, reproduction, comparative energetics, and toxicological sensitivity linked to metabolic rates.  
* Studying patterns in body size scaling relationships: The assumptions of the model quantify all energy and mass fluxes in an organism (including heat, dioxygen, carbon dioxide, ammonia) while avoiding using the allometric relationships. In addition, same parameters describe same processes across species: for example, heating costs of endotherms (proportional to surface area) are regarded separate to volume-linked metabolic costs of both ectotherms and endotherms, and cost of growth, even though they all contribute to metabolism of the organism. Rules for the co-variation of parameter values across species are implied by model assumptions, and the parameter values can be directly compared without dimensional inconsistencies which might be linked to allometric parameters.  Any eco-physiological quantity that can be written as function of DEB parameters which co-vary with size can, for this reason, also be written as function of the maximum body size.  
* DEB theory provides constraints on the metabolic organisation of sub-cellular processes. Together with rules for interaction between individuals (competition, syntrophy, prey-predator relationships), it also provides a basis to understand population and ecosystem dynamics.
