Where conditions for plant growth are less stressful, plants can evolve life history traits that fall along a continuum from competitors to ruderals.

Without the abiotic stressors and without frequent disturbances, plants can grow rapidly for long periods of time, and this creates more competition among plants for soil nutrients and light.

Competitors also tend to grow to larger sizes and exhibit long life spans.

About 75% of the charged residues in proteins are members of ion pairs that are located mostly on the protein surface.

Despite the strong electrostatic attraction interactions contribute little to the stability of a native protein.
