My research program consists of two broad, overlapping components: 1. evolution, ecology and conservation, and 2. systematics and taxonomy. Needless to say my interests are broad and I incorporate a variety of field, lab and experimental techniques in my research. I am particularly interested in processes of population divergence (particularly in mating traits) and the formation of new species. My main study system is hybrid zones between lineages of Green-eyed Treefrogs (Litoria serrata and L. myola) in rainforests of the Wet Tropics region of north-east Australia. These hybrid zones are fascinating and current projects revolve around determining the importance of reinforcement (increased premating isolation due to selection against maladaptive hybridisation) in speciation. Other projects I am currently working on include: targeted surveys for ‘missing’ and declined frogs; ecology and systematics of dipteran parasites of frogs; conservation of highly localised Queensland frogs and reptiles; and the invasion and impact of the Asian House Gecko in Australia.

Much of my research has involved frogs and reptiles but this has been largely a product of their suitability for the research questions to date. My interests are taxonomically broad.

Can species interactions cause rapid adaptation?

Indicative Funding
Under environmental change, the persistence of a species centers on its ability to disperse from or adapt to changing conditions. Dispersal is limited in the Australian Wet Tropics due to restricted environmental space and mountain-top edges, so adaptation is necessary. This includes adaption to the changing conditions (e.g., temperature) and changing species interactions. This project will use experimental evolution in two Australian rainforest Drosophila species to test if novel competition can drive adaptation to warming temperatures and enable coexistence. Results will then be used with field data to create a comprehensive niche model aimed at predicting effects of climate change to a Wet Tropics species.

Conservation of the Spotted?tailed Quoll across the Wet Tropics mountaintops

Indicative Funding
The northern subspecies of Spotted?tailed Quoll (Dasyurus maculatus gracilis) is genetically divergent, highly isolated, and restricted to high elevation rainforest of the Wet Tropics. It is listed as Endangered at both the Federal (EPBC) and State (NCA) level. Dasyurus m. gracilis has declined substantially due to a number of possible threats and only appears to survive in five small, disjunct areas across the central and northern Wet Tropics mountains. For effective management, it is vital that we understand the decline and genetic structuring of Spotted?tailed Quoll populations across the Wet Tropics. This project aims to: 1) Use distribution modelling to identify areas of quoll loss/persistence and assess possible reasons for the decline, in order to identify threats and key areas for conservation management, and 2) Use genomics to determine genetic structuring between subpopulations, in order to understand isolation and connectivity between populations and direct conservation actions

The impact of yellow crazy ants on key invertebrates, skinks and frogs of the Wet Tropics

Indicative Funding
This project aims to increase the understanding of the effects of the invasive yellow crazy ant. This will be achieved by conducting surveys of skinks, frogs and invertebrate across a number of sites. Certain sites will have crazy ant infestations, while others will be in similar, uninvaded habitats. Data from the invaded and uninvaded sites will be compared to examine the direct and indirect effects on biodiversity and community structure that yellow crazy ants have. This will allow us to better understand the risk they pose to the Wet Tropics World Heritage Area.

Threatened frog surveys Kuranda

Indicative Funding
Perform frog surveys on the KUR-World site and provide a report on threatened stream-associated frogs to NRA Environmental Consultants. Surveys will target threatened stream-breeding frogs after wet weather. The report will outline frog presence and abundance and recommendations on required habitat, stream buffers and ways to minimise ecological impacts.

Asian House Gecko Research

Indicative Funding
Research o the calling behaviour and movements of Asian House Geckos. This project will use experiments and field data to assess the determinants of calling behaviour in the Asian House Geckos. The results will be used to refine methods for detecting this invasive species. The research will also include a mark-recapture field study to understand the scalel of movements of Asian House Geckos in urban and bushland areas.
