Theory for relationships between thermal traits and body size

Develop a mechanistic theory that explains and predicts the documented empirical relationships between organismal body size and thermal response traits (e.g., minimum temperature T_min, thermal range T_ran, maximum temperature T_max, and optimum temperature T_opt) across taxa.

Background

The literature reports empirical relationships between body size and thermal traits (e.g., minimum temperature and range), as well as between thermal conduction-related quantities and size. However, the authors note a lack of a general theory explaining these patterns.

They suggest their framework could help illuminate principles behind these relationships, but acknowledge that a theory is currently absent.
