Title: Accelerations and the evolution of acceleration

Summary:

Application of the standard DEB model to a large number of animal species learned that quite a few species did not fit that model over their full life cycle. Deviations allowed a classifiaction in 5 modes of acceleration, which is defined as a long-term increase in metabolic rate during ontogeny, compared to expectations of the standard DEB model. I first briefly review some properties of the standard DEB model to introduce deviations from it. The 5 modes are an increase in maturation, assimilation, body temperature and changes in diet and morphy-type (temporary V1-morphy, as opposed to continued iso-morphy). I will discuss examples for each of these modes, and discuss ecological and evolutionary contexts where possible.
