WebAug 19, 2024 · Our results are consistent with hypotheses that diversity gradients reflect shifts in phenotypic optima signifying local temperature adaptation mediated by soil nutrient availability and metabolism. WebMar 1, 2024 · Two properties of the new phenotypic optima are the key. The first is the Euclidean distance between each optimum and the origin, d (assumed the same for both parental populations for simulations presented in main text). More distant optima yield a greater amount of genetic and phenotypic change.
