Frogs Victoria 2023 Mini-Conference

The Elgin Inn, Hawthorn

6th July 2023


Register now to give a short talk at the Frogs Victoria 2023 Mini-Conference.

Anything frog-related welcome!

Practice a talk or show off a polished presentation in front of a friendly, welcoming and knowledgeable audience. 


Talks can be 5 or 10 minutes, with optional question time.

For inspiration, check out last year's event

All are welcome in the audience - no RSVP/registration necessary

Evening starts at 5:30 pm for dinner and drinks (available for purchase),

talks start at 7pm



Join Craig Cleeland, self-confessed Southern Toadlet groupie who has been studying the species for over 20 years, for an immersion into this rapidly declining frog, with particular reference to Greater Melbourne. Craig will explore the dynamics of a population of Southern Toadlets in an effort to understand more about their breeding biology and life history. He will also report on at the results of toadlet occupancy surveys in the Shire of Nillumbik in 2018, along with data from four years of intensive surveys of the last remaining populations in the outer urban areas of Melbourne.

Spoiler alert: we're warned the ending's not great and not to expect too many answers!

Her current research focuses on the impact of the devastating disease, amphibian chytrid fungus, on reproduction and breeding display in Victorian frogs. She also works as a wildlife ecologist conducting surveys for threatened species in remote forest areas.

Lovesick? The effect of chytrid fungus infection on amphibian breeding display

The devastating amphibian chytrid fungus – caused by the fungal pathogen, Batrachochytrium dendrobatidis, (Bd) – has caused widespread amphibian declines and extirpations. Although the development of disease been examined in a range of species, little is known about its effect on reproduction. Here, we investigated how chytrid fungus affects male mating display in the critically endangered Alpine Tree Frog (Litoria verreauxii alpina). We collected call recordings of wild frogs in the field and used a spectrophotometer to analyse male breeding colouration, while swabbing all individuals for infection. We then analysed the call characteristics and colour profiles of infected and uninfected frogs to determine whether infection influenced calling performance and breeding colouration. We found that colouration in Alpine Tree Frogs was affected by chytrid fungus, with UV chroma increasing with infection status and load. These are the first results to show that chytrid fungus influences male breeding colouration. Calling performance was also closely linked to temperature variations within different amphibian microhabitats. The results that we present here are important but often overlooked aspects of disease ecology. We have shown that sublethal effects of disease can impact breeding behaviour and display. These changes in reproduction and breeding success in response to disease might have dramatic consequences on population trajectories and substantially influence population decline or recovery potential. It is therefore crucial that we investigate sublethal effects of infection and its influence on reproduction and recruitment, so that we can understand the impact of disease on populations.

Frogs of Borneo

From the Giant River Toad to impressive flying frogs and minuscule microhylids; Borneo is home to an incredible amphibian diversity! There are nearly 200 known species inhabiting a range of truly wild and ancient rainforest environments.
