We further show in our Supplementary how mutation effects in considered traits and temperature interact in simple thermodynamic models and can have a diversity of outcomes. Questions? Contact us.

Faster warm-edge expansion arises from larger mutation effects at higher temperatures. But that same property reduces predictability, as increased front variability counteracts selection's variance-reducing effect.

Thermodynamic models show a hotter-is-better trend reaching higher maximum growth rates at hotter temperatures, whereas the rate-depressing effects of cold keep expansion constrained along a decreasing thermal gradient. The Gaussian curve, on the other hand, expands easily along the colder gradient.

Enzyme Catalysis (the Macromolecular Rate Theory) + Protein Denaturation Model (Chen et al. 2010) + a Gaussian thermal performance curve are compared. Populations are initialised with near-identical thermal niches and expand along a decreasing and increasing temperature gradient.

We developed a mechanistic modeling framework to investigate how microscopic protein-level processes propagate across organizational levels to define macroecological patterns, specifically species range expansions.
