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.

Diversification and conservation of Australian frogs
- Indicative Funding
- $320,000 over 3 years (administered by Australian National University)
- We do not have a complete understanding of true diversity in any Australian plant or animal group with which we can test ideas about evolutionary diversification or conservation management. This Holy Grail is achievable in Australian frogs. We will utilise the massive Australian tissue collections and new genetic and analytical techniques to provide the most comprehensive assessment of cryptic diversity for any group of Australian animals and test hypotheses concerning the tempo of frog diversification. This information will be combined with novel analytical techniques developed in Australia to evaluate frog diversity protected currently and in the future under various climate-change scenarios. Our results will have wide applicability.

Targeted surveys for missing and critically endangered rainforest frogs in ecotonal areas, and assessment of whether populations are recovering from disease
- Indicative Funding
- $90,000 over 4 years
- Ten frog species disappeared from the upland rainforests of the Wet Tropics and Eungella during outbreaks of amphibian chytrid fungus (Batrachochytrium dendrobatidis) in the late 1980s and early 1990s. The exciting recent development is that we recently rediscovered one of these 'extinct' species, the Armoured Mistfrog (Litoria lorica) in high elevation dry sclerophyll forest close to rainforest sites it vanished from. We can now target very particular sites - ecotonal dry forests bordering rainforest - that have rarely been surveyed for these species and offer the maximum chance of success.

Using Bush Blitz to resolve cryptic reptile and frog groups of eastern Australia
- Indicative Funding
- $270,000 over 3 years
- This 3-year Fellowship will be for Conrad Hoskin to conduct taxonomy research on several poorly resolved reptile and frog groups. Amazingly, vertebrate species remain to be described from eastern Australia, particularly from 'cryptic' reptile and frog groups. We will target four groups - Lampropholis skinks, Oedura geckos, Phyllurus geckos, and microhylid frogs-recognised 'problem' groups. We will integrate Bush Blitz survey collections with our extensive genetic and morphology data and museum collections to resolve species diversity of these key vertebrate groups, in the process describing highly localised, climate-sensitive species and shedding light on patterns of landscape diversity.

Why are there so few hybrids in the Green-eyed Treefrog hybrid zone? Resolving the role of behaviour versus genetics
- Indicative Funding
- $27,800 over 2 years
- The question of how species are formed (speciation) remains an integral question in evolutionary biology, in particular whether species can form through hybridization. Studies by the two investigators here on two hybrid zones between genetic lineages of the Green-eyed Treefrog (Litoria serrate) have shown that a new species formed in one hybrid zone (Kuranda) but not at the other (Lamb Range). There appears to be no hybrids at the Kuranda hybrid zone and very few at the Lamb Range hybrid zone. Here we will test why hybrids are so rare and in doing so will address big questions in speciation research.
