Effective population size.
The effective population size of the koala population was significantly
impacted by each of the disturbance processes (CI for each dataset did
not overlap with each other). The population decrease caused by
‘natural’ mortality events resulted in a 30.98% decrease in
Ne (Dataset 1 vs Dataset 2). The additional population
decline caused by the linear transport infrastructure project by virtue
of translocations and the subsequent creation of two smaller
sub-populations resulted in a 26.16% decline in Ne for
the population of koalas located below the linear transport
infrastructure (Dataset 2 vs Dataset3above) and a 9.3%
decline in Ne for the population of koalas located above (Dataset 2 vs
Dataset3below) the linear transport infrastructure (see
Table 1).
