Unravelling why metabolic rate scales with body size (108972)

Project Details


The rate at which organisms expend energy and require food and oxygen – their metabolic rate – changes (scales) with body size, but usually out of proportion; for a given increase in size, metabolic rate increases less. Why this is so, and why there appears to be variation in how steep this scaling relationship is among species, are some of the biggest unanswered questions in biology.

In this project, we will use comparative studies and multi-generational artificial selection experiments with fish as model organisms, in combination with genetic analyses, to unravel why and how metabolic rate scales with body size.

This project is funded by Independent Research Fund Denmark (DFF).
