TESS postgraduate students are encouraged to present at the annual TESS retreat (4 and 5 of November, 2019)
1) UneXtinct and 2) Fungi and the Sahul-Sunda Exchange
Wednesday, 16th October 2019 | Presented by Dr Ashley Field & Dr Matt Barrett | (ATH/JCU)
1) Concern about an extinction crisis in Australia is palpable. There are, however, a growing list of species that have become ‘unextinct’. ‘Unextinction’ happens in three ways, through a species being rediscovered, through the taxonomic validity of a species being revaluated or through the veracity of original records being reconsidered. I explore the Australian plant extinction record based on the recent reviews of Silcock et al. (2019) To Name Those Lost, which proposes a framework for validating records; and Field and Renner (2019) Rediscovered or reconsidered, which explores in detail the veracity of the record of fern extinctions in the north Queensland mountaintops, the area hitherto considered to have lost the most number of species of any plant group.
2) Fungal spores are usually dispersed by wind, and have the potential for intercontinental dispersal, matching the “everything is everywhere” hypothesis. However spores dispersal has been shown to be strongly leptokurtic even over short distances, with geographic structuring at all scales. Biotic exchange between the Sunda and Sahul shelves has been little studied from a fungal perspective, but is a useful model system to explore rates of intercontinental dispersal over time. Unfortunately, the fungi of key areas for exchange in northern Australia and Indonesia biomes are among the least explored in the world. The current state of knowledge of fungal biogeography in the Sahul-Sunda area will be summarised, and some emerging trends discussed in light of ecological associations. Natural patterns of fungal dispersal have implications for arrival and spread of fungal diseases in northern Australia.
