Diversity cascade for brush-tailed rabbit-rats, showing the amount of genetic diversity held within and among hierarchical strata.
| Parameter | Lineage | Population | Diversity value |
|---|---|---|---|
| γ = Q(GT) | 0.184 | ||
| δ = Q(AR) | 0.091 | ||
| σ = Q(WR) | Mainland | 0.097 | |
| Tiwi Islands | 0.113 | ||
| β = Q(AP/WR) | Mainland | 0.014 | |
| Tiwi Islands | 0.008 | ||
| α = Q(WP/WR) | Mainland | Cobourg East | 0.094 |
| Mitchell Plateau | 0.060 | ||
| Tiwi Islands | Bathurst Island | 0.056 | |
| Melville Island | 0.121 |
GT grand total, AR among region/lineage, WR within region, AP/WR among population within region, WP/WR within population within region.
Two populations on the Australian mainland and two populations on the Tiwi Islands were used in the analysis. The Q diversity value is derived from Rao’s Quadratic Entropy, a commonly used measure of diversity in ecological communities, with values converted into an analogue suitable for genomic data.
