Purpose of Review

The increasing impact of droughts, wildfires and windstorms in temperate areas poses a significant challenge to the adaptation capacity of forests and their associated arthropod communities. Organisms, organic material, and environmental conditions occurring after disturbances, i.e. the disturbance legacies, shape arthropod communities during their transition from pre- to post-disturbance conditions. We describe the contribution of disturbance legacies to the organization of forest arthropod communities following droughts, wildfires, or windstorms. We also highlight how forest conditions, arthropod traits and post-disturbance management influence disturbance legacies and their impact on arthropod communities.

Recent Findings

Key disturbance legacies include surviving arthropods, micro-environmental legacies, and tree- and ground-related resources. Most of these are driven by canopy openness and tree condition. For arthropods, dispersal ability and other biological and demographic traits determine their vulnerability to disturbances, but also their capacity to colonize post-disturbance microhabitats, and withstand micro-environmental legacies. Dominant tree species and management strategies influence disturbance regimes and mediate the pattern of their legacies. Droughts, wildfires and windstorms have idiosyncratic effects on disturbance legacies, and arthropod taxa can have specific responses to legacies, making it difficult to predict the likely composition of post-disturbance arthropod communities.

Summary

This review highlights a particular gap in our understanding of the effects of drought on forest arthropod communities and the need for more research in this area. In addition, a better understanding of how forest arthropod communities are altered by changes in disturbance regimes is urgently needed. Our goal is to foster an improved understanding of the role of disturbance legacies for forest arthropod communities in order to improve management decisions and promote the conservation of forest arthropod species.

在不断变化的森林中生存：非生物干扰对温带森林节肢动物群落的遗留影响

审查目的

温带地区干旱、野火和风暴的影响日益严重，对森林及其相关节肢动物群落的适应能力提出了重大挑战。扰动后发生的生物体、有机物质和环境条件，即扰动遗产，在节肢动物从扰动前条件到扰动后条件的转变过程中塑造了节肢动物群落。我们描述了干旱、野火或风暴后干扰遗产对森林节肢动物群落组织的贡献。我们还强调了森林条件、节肢动物特征和干扰后管理如何影响干扰遗产及其对节肢动物群落的影响。

最近的发现

主要的干扰遗产包括幸存的节肢动物、微环境遗产以及树木和地面相关资源。其中大部分是由树冠开放度和树木状况驱动的。对于节肢动物来说，分散能力和其他生物和人口特征决定了它们对干扰的脆弱性，也决定了它们在干扰后微生境中定居和承受微环境遗产的能力。优势树种和管理策略影响干扰机制并调节其遗产的模式。干旱、野火和风暴对扰动遗产具有特殊影响，而节肢动物类群可以对遗产产生特定的反应，因此很难预测扰动后节肢动物群落的可能组成。

概括

这篇综述强调了我们对干旱对森林节肢动物群落影响的理解上的一个特殊差距，以及在这一领域进行更多研究的必要性。此外，迫切需要更好地了解森林节肢动物群落如何因干扰制度的变化而改变。我们的目标是加深对森林节肢动物群落干扰遗产作用的了解，以改进管理决策并促进森林节肢动物物种的保护。
