New Windows into the history and diversity of the Australian Biota

Speaker: Dr Paul Oliver

Location: 11:30 am to 12:30 pm in Building 6, Level C, Room 12

The biota of Australia and surrounding islands is famously diverse and unique. But what historical processes underpin this? Combinations of climatic perturbation, long-term aridification and isolation have long been invoked as the prime explanations. Emerging techniques and increasingly large phylogenies provide new opportunities to investigate the relative roles of these processes with greater statistical rigour than ever before. However, at the same time our baseline biodiversity inventory still remains surprisingly incomplete for many groups and areas, a deficiency that has

Identification, distribution and diet of Tasmanian predators inferred by scats

Speaker: Elodie Modave

Location: 11:30 am to 12:30 pm in Building 6, Level C, Room 12

Elodie is interested in the Tasmanian predator identification, diet and modeling through analyzing scat (i.e. feces) DNA. Elodie developed a mini-barcode to be able to identify large mammalian Australian predators using a small portion of DNA and tested this barcode for its accuracy, effectiveness and sensitivity. Once it proved successful, she then modeled the distribution of Tasmanian predators by successfully applying this marker on more than 700 scats. Elodie obtained patterns of co-occurrence of species and habitat characteristic impacts that

Snails and copper: an intergenerational story of toxicity, adaptation and death

Speaker: Rod Ubrihien

Location: 11:30 am to 12:30 pm in Building 6, Level C, Room 12

Mining, urban, industrial and agricultural use has greatly increased the concentration of copper in the biosphere. Despite being an essential element, copper is toxic when present at concentrations above biological requirements. Copper sulfate has been used as a pesticide to control freshwater snails in rice fields for over 40 years. The chemical properties of copper and repeated use means that copper will accumulate in these areas. This will result in organisms being exposed to toxic sublethal levels of copper. My
