Genomic approaches to track and monitor marine biodiversity in coastal ecosystems
Dr Joey DiBattista, Research Scientist, Australian Museum

Biodiversity plays a critical role in the resilience of natural systems, and there is a directed effort towards understanding current threats to biodiversity (e.g. climate change). The emerging field of environmental DNA (eDNA) is transforming our approach to how we assess biological diversity and ecosystem function. eDNA is used to describe DNA shed from secretory processes such as the sloughing of skin, scales, mucus, eggs, sperm, blood, or defecation, and can be used to provide a record of a species presence. When combined with recent advancements in next-generation sequencing (NGS) and bioinformatics, the diversity of organisms from environmental samples that contain mixtures of DNA signatures can be recovered. As such, eDNA metabarcoding can provide a wealth of information for studies of biodiversity, food web dynamics, diet analysis, and for environmental and invasive species monitoring. I will highlight studies in a number of coastal marine ecosystems based on the development and application of eDNA metabarcoding for studying fish biodiversity across spatial and temporal scales, the analysis of stomach contents to understand fish diet and the trophic levels of marine taxa, and also methods development around laboratory protocols and taxonomic assignments. We additionally highlight how these advances might be incorporated into existing or new marine monitoring programs around Australia. 

Lampung supplementary weft textiles
Dr Chris Reid, Research Scientist, Australian Museum

Indonesia has one of the most diverse traditions of textile production on the planet, a product of early trade with both India and China, and later trade with Europe. And in Indonesia, the province of Lampung has, or at least had, the greatest diversity of textile types and styles. Lampung was primarily inhabited by Lampungese but due to Javanese transmigration these indigenous people now represent only 14% of the population. One weaving method that was formerly made throughout the province but ceased in about 1900 is supplementary weft. This talk will explore the supplementary weft textiles of Lampung, especially squares of cloth called tampan, with regard to the history of the area, regional dialects, dating and origins of motifs.
