Hypothesis 3
H3: Introduced species diverge evolutionarily
from native populations
a. Prediction: Introduced populations experience a reduction in
genetic diversity compared to native populations (bottlenecks)
b. Prediction: Multiple independent introductions to one region
increases genetic diversity (hybridizing and outcrossing with native
species or other invaders)
c. Prediction: (adaptive evolution) Introduced species locally adapt to new biotic environment, and members of the invaded community adapt to the presence of the invader.
