Globally, the mean abundance of terrestrial animals has fallen by 50% since 1970, and populations face ongoing threats associated with habitat loss, fragmentation, climate change and disturbance. Climate change can influence the quality of remaining habitat directly, and indirectly by precipitating increases in the extent, frequency and severity of natural disturbances such as fire. Species are confronted with the combined threats of habitat clearance, changing climates and altered disturbance regimes, each of which may interact and have cascading impacts on animal populations. Typically, conservation agencies are limited in their capacity to mitigate rates of habitat clearance, fragmentation or climate change, yet fire management is increasingly used worldwide to reduce wildfire risk and achieve conservation outcomes. A popular approach to ecological fire management involves the creation of fire mosaics to promote animal diversity; however, this strategy has two fundamental limitations: (1) the effect of fire on animal movement within or among habitat patches is not considered; and (2) the implications of the current fire regime for long term population persistence are overlooked. Spatial and temporal patterns in fire history can influence animal movement, which is essential to the survival of individual animals, the maintenance of genetic diversity, and the persistence of populations, species and ecosystems. We argue that there is rich potential for fire managers to manipulate animal movement patterns, enhance functional connectivity, gene flow and genetic diversity, and increase the capacity of populations to persist under shifting environmental conditions. We describe a suite of recent methodological advances, including spatio-temporal connectivity modeling, spatially-explicit individual-based simulation, and fire-regime modeling, and explain how these tools can be integrated to achieve better outcomes for biodiversity in human-modified, fire-prone landscapes. Article impact statement: Land managers may conserve populations by using fire to sustain or enhance functional connectivity. This article is protected by copyright. All rights reserved.

整合功能连接和火灾管理以获得更好的保护结果

在全球范围内，陆生动物的平均丰度自 1970 年以来下降了 50%，人口面临与栖息地丧失、破碎化、气候变化和干扰相关的持续威胁。气候变化可以直接或间接地影响自然干扰（如火灾）的范围、频率和严重程度的增加，从而影响剩余栖息地的质量。物种面临着栖息地清除、气候变化和干扰机制改变的综合威胁，每一种都可能相互作用并对动物种群产生连锁影响。通常，保护机构在减缓栖息地清除率、破碎化率或气候变化率方面的能力有限，但全球范围内越来越多地使用火灾管理来降低野火风险并实现保护成果。一种流行的生态火灾管理方法涉及创建火灾马赛克以促进动物多样性；然而，这种策略有两个基本的局限性：（1）没有考虑火灾对栖息地斑块内或栖息地之间的动物运动的影响；(2) 目前的火灾制度对长期人口持续存在的影响被忽视了。火灾历史中的时空模式会影响动物的运动，这对个体动物的生存、遗传多样性的维护以及种群、物种和生态系统的持久性至关重要。我们认为，火灾管理者在操纵动物运动模式、增强功能连接、基因流动和遗传多样性以及提高种群在不断变化的环境条件下生存的能力方面具有巨大的潜力。我们描述了一系列最近的方法论进展，包括时空连通性建模、基于空间的显式个体模拟和火灾模式建模，并解释了如何整合这些工具以在人类改造、火灾中实现生物多样性的更好结果。 - 容易出现的风景。文章影响声明：土地管理者可以通过使用火来维持或增强功能连通性来保护人口。本文受版权保护。版权所有。土地管理者可以通过使用火来维持或增强功能连通性来保护人口。本文受版权保护。版权所有。土地管理者可以通过使用火来维持或增强功能连通性来保护人口。本文受版权保护。版权所有。
