Figure 2. Forward
dispersal simulations show the effect of the number of dispersing koalas
on the extent of genetic connectivity from 1-10 generations after the
subdivision between the koala populations located on either side of the
linear transport infrastructure (above and below). Genetic
differentiation was measured using Fst, Gst and Mutual Information (MI).
The forward-simulations imported the genetic data from the two
post-construction datasets (Dataset3above = 27 koalas
and Dataset3below = 75 koalas) as a starting point. The
starting point of these connectivity measures at generation 0 were: Fst
= 0.005, Gst = 0.006 and MI = 0.003. We simulated a total of 12
dispersal treatments.
