Table 1. Patterns of genetic diversity. Dataset 1 represents the resident koala population without any natural or linear transport infrastructure impacts. Dataset 2 represents the resident koala population impacted by ‘natural’ mortality events. Dataset 3above represents the remaining resident koala impacted by the linear transport infrastructure and located above the rail line. Dataset 3belowrepresents the remaining resident koala population impacted by the linear transport infrastructure and located below the rail line. (N) indicates sample size, (He) expected heterozygosity, (Ho) observed heterozygosity, (\({}^{0}D\)) number of different types of alleles (allelic richness), (\({}^{1}D\)) exp(Shannon’s diversity index), (\({}^{2}D\)) 1/(1-He) and effective population size (Ne). Estimates include ± 95% confidence intervals.
