how anthropogenic stressors alter aquatic environments
About the lab
We are interested in how anthropogenic stressors alter aquatic environments. How do stressors, such as heatwaves, species invasions, and habitat loss interact to affect individuals, communities and entire ecosystems?
Nature is under increasing threat from anthropogenic activity – human population growth and economic development impose increasing pressure on the planet’s ecosystems. The planet is warming, extreme weather events are becoming more frequent and, at the same time, habitats are being destroyed and polluted.
These stressors rarely occur in isolation, so the traditional focus on single stressors will inevitably miss key information on their interactive, and often counterintuitive, impacts. We aim to derive generalities in how aquatic ecosystems respond to multiple stressors by focusing on both multiple levels of organisation (from genes to ecosystems) and multiple scales (from laboratory experiments to field studies).
Our Projects
Our Projects at the Jackson Lab encompass a diverse range of research endeavors, all aimed at unraveling the complexities of human-induced pressures on aquatic environments. From investigating stressor interactions in global marine ecosystems to employing genomic tools for biomonitoring, our team is dedicated to advancing our understanding of aquatic ecosystems and informing effective conservation strategies.

Dr Michelle C Jackson
PI
I joined Oxford from Imperial College London in 2019. I am broadly interested in the effects that humans have on aquatic ecosystems. In particular, I am interested in how multiple stressors interact, and the implications for trophic interactions.
Adriana Mordente
PhD Student
I joined the Jackson Lab after studying at the University of Buenos Aires, Argentina and building up experience in Germany. My main area of interest relies on community-to-ecosystem level responses to environmental change in aquatic ecosystems. I’m particularly interested in using genomic tools for biomonitoring environmental change.
Dr Sam Macaulay
Postdoc
My research focuses on the effects of anthropogenic stressors associated with land use change, chemical contamination and climate change in aquatic ecosystems. I am interested in understanding how multiple stressors interact to affect ecosystem diversity and functioning.
Ramesh Wilson
PhD Student
I joined the Jackson Lab after completing a BSc at Queen Mary, University of London. My DPhil explores multiple stressor effects on global marine intertidal and benthic communities, using a combination of passive in situ and experimental methods. I am also interested in ecological policy and evidence-led litigation in aquatic and terrestrial systems.
Buntu Fanteso
PhD Student
I joined the Jackson Lab after completing an MSc in Environmental Management from the University of Johannesburg in South Africa. My research involves fieldwork in South Africa and experiments in the UK to understand the effects of multiple stressors and their interactions on aquatic ecosystems.
Controlled Experiments
We use indoor aquaria and outdoor ‘mesocosm’ ponds and streams to manipulate stress conditions and quantify how populations and communities respond.
We have three mesocosm facilities:
- Oxford mesocosms: 32 large mesocosm ponds – long term experiment on warming and drought running since 2020
- InterStressor: 128 small mesocosm ponds for short term pulsed stressor experiments
- ExStream: 128 small transportable stream mesocosms for short term experiments
We also work with Guy Woodward and Emma Ransome at Imperial College London on a large scale mesocosm warming experiment (pictured).
Field Research
Our field research spans from pole to pole. To complement our experiments (which have high control but lack realism) we measure gene to ecosystem responses across natural and anthropogenic stress gradients.
For instance, we use natural geothermal temperature gradients in Antarctica to quantify how intertidal and lake communities respond to warming (pictured). In South Africa, we have a project which is investigating how stream food webs vary across land use gradients.
