WebA theory for the expression of a population's response to density-independent gradients of environmental factors is derived for the case of asexuality. It is shown that the environmental tolerance of a genotype is a function of at least four parameters: g$_1$ and V$_{E1}$, the environmental optimum and its developmental variance between … WebMay 14, 2024 · limits of tolerance The upper and lower limits to the range of particular environmental factors (e.g. light, temperature, availability of water) within which an organism can survive.
