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.
