Devastation of both natural and human habitats due to wildfires is becoming an increasingly prevalent global issue. Fire-adapted and fire-prone regions, such as California and parts of Australia, are experiencing more frequent and increasingly destructive wildfires, accompanied by longer wildfire seasons. Further, wildfires are becoming more commonplace in areas that historically do not regularly experience fire, causing an increased risk of habitat loss in less resilient ecosystems. The escalation of fire outbreaks is a result of several factors; however, at the forefront of these outbreaks is an increase in highly flammable dry vegetation due to sustained drought, a trend we will see growing in our changing climate. To mitigate the potentially detrimental outcomes of wildfires, it is imperative that we understand the response of ecosystems to fire not only from an ecological perspective, but also from a physiological perspective. Research focused on the physiological adaptations of organisms to environmental constraints caused by fire can give insight into how plants and animals respond to fire, on both short- and long-term scales. Importantly, this information needs to be adapted effectively into fire management plans to improve the recovery success of organisms after fire.
由于野火,自然和人类栖息地的破坏正成为一个日益普遍的全球问题。适应火灾和易发生火灾的地区,如加利福尼亚和澳大利亚的部分地区,正经历着更频繁和更具破坏性的野火,野火季节也更长。此外,在历史上不经常发生火灾的地区,野火也变得越来越普遍,这增加了生态系统恢复力较低地区的栖息地丧失风险。火灾爆发的升级是由多种因素造成的;然而,这些爆发的最前沿是由于持续干旱导致易燃干燥植被的增加,这一趋势在我们不断变化的气候中将会加剧。为了减轻野火可能带来的不利后果,我们必须从生态和生理角度了解生态系统对火灾的反应。关注生物体对火灾引起的环境限制的生理适应的研究,可以深入了解植物和动物对火灾的短期和长期反应。重要的是,需要将这些信息有效地应用于火灾管理计划中,以提高火灾后生物体的恢复成功率。
