Professor Karen Gibb is an environmental microbiologist with 30 years research experience.
Professor Gibb is currently Director of the Research Institute for the Environment and Livelihoods and is an active researcher in the Environmental Chemistry and Microbiology Unit (ECMU) at Charles Darwin University. The ECMU is a research and commercial unit that has research strengths in determining the source of contaminants and interpreting changes in marine, estuarine and aquatic environments.
ECMU’s research has supported important improvements in the methodologies and policies that underpin the sustainable management of marine, estuarine and aquatic systems across northern Australia. Government now mandates some of the methodologies developed by ECMU for environmental monitoring.
The core research strengths of the ECMU are:
HDR Project Opportunities with Professor Gibb Water and land stewardship
Professor Gibb and her team are interested in developing and evaluating efficient tools and protocols for mapping and monitoring environmental values relating to biodiversity and water. This will involve remote sensing and ‘direct’ terrestrial biodiversity and water research to underpin metrics for biodiversity market development. At demonstration sites, Professor Gibb's team aim to quantify existing biodiversity and water-related environmental values on country under different land uses and evaluate gains resulting from management interventions. What land management activities provide greatest biodiversity return on investment?
The project team will analyse site-level assessment to track signatures of different inputs from various sources (for example, land runoff, creeks, or wetlands) into a river over time. The signatures are based on microbial DNA and changes in management practises (reduced stocking and fencing of riparian zone) can result in a measurable reduction in signatures from a source which can equate to a management gain.
A PhD project linked to this project would involve developing bacterial indicators specific for different faecal sources (such as cattle, feral and wildlife) which allow the differentiation and semi-quantification of faecal inputs into the river compromising water quality.
In a second project, the team is also interested in site-level assessments of fish species diversity - baseline data with an option for more detailed assessment if further funding is sourced. The rationale is that fish species diversity is an important metric for water quality and alternative income opportunities, for example ecotourism or fishing
