eDNA for Global Environment Studies (eDGES)
The eDGES program focuses on developing and applying environmental DNA (eDNA) techniques to address challenges related to biodiversity loss and sustainability in our changing world.
Through our scientific achievements we seek to understand ecological and evolutionary changes in natural and man-made landscapes, to develop new-generation tools for identifying and managing species, and foster biodiversity conservation through whole community studies afforded to us by eDNA.
Beyond the research, our goal is to translate this knowledge into outcomes for society that will ultimately enhance our collective wellbeing.
- eDGES is funded by BHP’s Social Investment Framework, ‘Environment’ stream by contributing to “biodiversity conservation, water stewardship and climate change mitigation and adaptation.”
- Has five distinct projects – each builds and expands the utility of eDNA as a biological biomonitor
- Begins in 2020 and will run for 5 years
- Multiple leveraging aspects anticipated; local and international PhD training, peer reviewed papers, associated grant augmentations (eg ARC Linkages), community education, policy input.
- Public awareness events; seminars, annual stakeholder meetings, end-of-program symposium
- Contributes to the strategic BHP-Curtin Alliance (signed July 2020), whose goal is innovation, education and research
Aims to merge eDNA monitoring with whole genomic analyses to study the Pilbara Olive Python (Liasis olivaceus barroni), resulting in deep population genomic insights and evolutionary ecology information to guide conservation priorities. A key outcome in this study will be the generation of the first Olive Python reference genome.
Develops new high-resolution eDNA tools for monitoring genetic diversity in subterranean animals across different sites, in order to facilitate their conservation and obtain new groundbreaking information into the evolutionary processes in this hidden world.
Project 3 – Functional ecology of Chilean precordillera lakes: towards a Wetland Health Index for birds
By uniquely combining eDNA technology with isotope analysis this project aims to not only investigate the wetland biodiversity but also characterize ecosystem web dynamics from sediment microbes to the migratory Chilean flamingos. This will allow us to understand the food chain and identify keystone species that are indicators of wetland health.
Project 4 – Improve Sensitivity and Specificity of eDNA metabarcoding tools for Invasive Marine Species detection
This project aims to develop crucial target information of invasive marine species (IMS) and native co-inhabitants from the North West Shelf of Western Australia. This will greatly enhance the ability of eDNA to detect IMS in ports, ballast and structural waters to become the first line of defence in the seas.
Project 5 – Benthic communities associated with the Griffin pipeline Infrastructure: Targeting invasive marine species
Environmental DNA samples will be collected from manmade assets and natural habitats across the Griffin oil field infrastructure to identify patterns in the distribution of organisms and preferences for structure types and depth. This sampling will investigate invasive marine species and native biodiversity.
