A tipping point for tipping points

Oikos, EarlyView.
Tipping points (TPs) – often understood as abrupt changes to a system – have become a popular framework for ecology and environmental science across spatial and temporal scales. The underlying, quantitative foundation of TP theory is built on mathematical models from catastrophe and predator–prey theories.

Dominant deer mice show the importance of abundance in competition

Ecosphere, Volume 17, Issue 3, March 2026.
Abstract Detecting competitive interactions is important for predicting species responses to environmental change but remains challenging, especially over large scales. Modern coexistence theory predicts that reduced ecological trait overlap promotes coexistence through stabilizing mechanisms, while fitness differences generate competitive asymmetries.

Integrating agent‐based models into the ensemble ecosystem modelling framework: A rewilding case study at the Knepp Estate, UK

Ecological Solutions and Evidence, Volume 6, Issue 1, January–March 2025.
In this study, we integrate an agent‐based model (ABM) with an ensemble ecosystem model (EEM) to assess the impacts of rewilding at the Knepp Estate, UK. The ABM‐EEM approach captures spatial and individual‐level dynamics and reveals emergent behaviours, such as increased woodland regeneration in thorny scrubland with large herbivores present.

Exploratory modeling of social‐ecological systems

Ecosphere, Volume 15, Issue 10, October 2024.
Abstract Navigating social‐ecological systems toward sustainable trajectories is an important challenge of the Anthropocene. Models of social‐ecological systems can increase our understanding of how social and ecological subsystems interact, their response to environmental changes, and how their dynamics may be altered by management interventions ...
