Adaptive plant traits under anthropogenic burning regimes: A database for UK heath and mire plant species

open access: yesAmerican Journal of Botany, Volume 112, Issue 10, October 2025.
Abstract Premise Humans have used fire to manage landscapes for millennia, but this use of fire is declining in many ecosystems. Understanding how plants respond to these changes is key to predicting ecosystem resilience and impacts on services such as biodiversity and carbon sequestration. However, many ecosystems lack data on plant fire responses.

Testing key tenets of pyro‐ecophysiology: Indicators of drought response in relation to shoot flammability

open access: yesAmerican Journal of Botany, Volume 112, Issue 10, October 2025.
Abstract Premise Relationships between flammability and drought tolerance influence vegetation dynamics during fires. A goal of the emerging subdiscipline of pyro‐ecophysiology is to identify ecophysiological traits that determine live fuel flammability, but empirical studies of these relationships are rare.
