Greta is currently doing her project on the ‘Phylogeography and population genetics of the long-nosed potoroo’ in simple terms Greta is investigating the genetic diversity present across the range of the long-nosed potoroo at both a broad landscape scale (phylogeography) and at a local population level (population genetics). The genetic and ecological data collected will assist in the management of this endangered species which has a highly limited and patchy distribution which has been heavily impacted on by land clearing and habitat fragmentation as well as the introduction of exotic predators.

The phylogeographic analysis will help define the most appropriate geographic scale for conservation management of this species, as well as identify any historically isolated and genetically distinct populations which may require special management considerations. The analysis of the population genetics at a local scale will help determine population processes such as mating systems, patterns of paternity, dispersal capabilities of males and females, as well as identify the level of connectivity and current gene flow between neighbouring populations.

The Mt Rothwell population is a free ranging captive population of unknown provenance. Greta’s analysis will be able to pinpoint where the Mt Rothwell potoroos originated from in the wild, as well as whether this population behaves in the same manner as wild populations do in regard to breeding and movement patterns.

Knowing the provenance of the Mt Rothwell potoroos will assist in future re-introductions into the sanctuary by identifying what genetic stock would be the most appropriate to bring into the current population, guaranteeing the future genetic integrity of the Mt Rothwell long-nosed potoroo population.
