  1. Selection pressures act against plants in the middle of the trait distribution is a result of disruptive natural selection

  2. Selection pressures act against plants in the short and medium of the trait distribution is a result of directional natural selection

  3. Selection pressures act against plants in the short and tall of the trait distribution is a result of stabilized natural selection

  4. Selection pressures random act against plants in the any of the trait distribution is a result of cyclic natural selection
