Dr Alice Johnston
NERC Research Fellow
Areas of Interest
- Combining novel energy budget and individual-based simulation models to investigate how animal populations respond to spatially explicit land management scenarios.
- The use of mechanistic modelling approaches to better understand the relationships between soil organisms, management practices, and extreme weather events.
- Investigating how earthworms act as ecosystem engineers in soils by linking earthworm activities to soil functions and ecosystem services.
- Quantitative methods for integrating nutritional ecology in energy budget and individual-based models.
- I am also interested in the economic valuation of ecosystem services and the expansion of modelling approaches to include socio-economic interactions.
