Figure 1 – Predicted
genetic erosion for each genetic dataset using observed heterozygosity
calculated from respective SNP datasets and with Ne adjusted for
proportion of males (30%) that contribute to next generation calculated
from breeding success in observed pedigree in this population of koalas
(Schultz et al. 2020). Dataset 1 represents the predicted genetic
erosion patterns for the resident koala population without any natural
or linear transport infrastructure impacts. Dataset 2 represents the
predicted genetic erosion patterns for the resident koala population
impacted by ‘natural’ mortality events. Dataset 3aboverepresent patterns of genetic erosion for the resident koala impacted by
the linear transport infrastructure located above of the rail line
infrastructure. Dataset 3below represent patterns of
genetic erosion for the resident koala impacted by the linear transport
infrastructure located below of the rail line infrastructure. Shannon’s
diversity index showed the same trends, see Figure S1 in Appendix 1.
