Altered fire regimes resulting from climate change and human activity threaten many terrestrial ecosystems. However, we lack a holistic and detailed understanding of the effects of altering one key fire regime component - season of fire. Altered fire seasonality can strongly affect post-fire recovery of plant populations through interactions with plant phenology. We identify seven key mechanisms of fire seasonality effects under a conceptual demographic framework and review evidence for these. We reveal negative impacts of altered fire seasonality and identify research gaps for mechanisms and climate types for future analyses of fire seasonality effects within the identified demographic framework. This framework and these mechanisms can inform critical decisions for conservation, land management, and fire management policy development globally.
气候变化和人类活动引起的火灾发生规律的改变威胁着许多陆地生态系统。然而，我们缺乏对改变火灾发生规律的一个关键组成部分——火灾季节的全面和详细的了解。改变火灾季节性可以通过与植物物候的相互作用强烈影响火灾后的植物种群恢复。我们在概念性的种群框架下确定了七个关键的火灾季节性影响机制，并回顾了这些机制的证据。我们揭示了改变火灾季节性的负面影响，并确定了未来在确定的种群框架内分析火灾季节性影响的机制和气候类型的研究空白。该框架和这些机制可以为保护、土地管理和火灾管理政策的制定提供决策依据。
