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.
