Figure 1. Four predicted sources of within-species variation in
HP receipt across spatial scales depicted here as two populations.
Examples of studies providing supporting evidence for the role of each
source of variation in mediating HP transfer dynamics are presented.
Figure 2 Three predicted sources of within-species variation in
the intensity of HP effects across spatial scales depicted here as two
populations. Examples of studies providing supporting evidence for the
role of each source of variation in mediating HP effects are presented.
