Groundwater and community ecotoxicology research
The Freshwater Ecology and Ecotoxicology Lab at Macquarie University leads research on groundwater and freshwater ecosystems, focusing on the impacts of pollution and environmental change.
We develop science-based guidelines to protect these environments. Our lab is equipped for advanced field and molecular studies, with facilities including:
- an on-campus mesocosm system
- eDNA analysis
- high-level microscopy
- water quality equipment.
Research and consultancy
The Freshwater Ecology and Exotoxicology Lab consults and conducts research across three main themes.
We are world leaders in groundwater ecology and pioneered methods for assessing groundwater ecosystem health. Our research examines how invertebrate and microbial communities respond to environmental change and develops tools to track ecosystem condition.
We specialise in groundwater invertebrate taxonomy and environmental DNA (eDNA) to analyse ecosystem composition and function, establishing an international reputation in the field. Current projects focus on:
- groundwater ecosystem ecology and health assessment
- ecological risk assessment and ecotoxicology
- the role of stygofauna in providing ecosystem services.
Our team investigates human impacts on surface and groundwater ecosystems, with expertise in multi-species and mesocosm toxicity testing. On campus, we maintain a 24-pond mesocosm system and run advanced stream and microcosm studies.
We developed novel toxicity testing approaches using stygofauna and groundwater microbes, and co-authored guidelines for groundwater fauna testing. Our field studies extend from arid NSW landscapes to the sub-Antarctic Macquarie Island.
We have a strong history in river ecology, health assessment and stream macroinvertebrate research. Our team has published widely on river health and regularly applies the AUSRIVAS method in consultancy projects.
Opportunities
- Volunteering and work experience: Get involved in our research through lab work, invertebrate ID or fieldwork. We provide training, inductions and a supportive learning environment.
- Project students: We offer diverse projects for undergrad and postgrad students, from lab-based studies to data analysis, writing,and fieldwork.
