1.火烧特征的变化，称为热解多样性，在火灾后群落的结构中起着重要作用，但对热解多样性对单个物种的重要性知之甚少。如果火灾相关物种在不同的生活史阶段需要不同的资源，那么火灾后多样化的栖息地的可用性可能是它们的关键。2.我们测试了火灾后的专家黑背啄木鸟的特定年龄栖息地关系。我们使用无线电遥测技术跟踪烧毁森林中的幼龄和成年啄木鸟，并建立了资源选择函数，以比较成鸟和幼鸟之间林分、树木和林木水平协变量的影响。3.幼龄黑背啄木鸟选择的栖息地比成年啄木鸟活树多，使用的异质栖息地烧毁严重程度较低，说明年龄对栖息地选择有很强的影响。在选定的林分中，与成虫相比，雏鸟使用障碍的可能性较小，而使用活树的可能性更大，但两个年龄段都显示出对较大直径树(活树和死树)的强烈正向选择。完毕
1. Variation in fire characteristics, termed pyrodiversity, plays an important role in structuring post-fire communities, but little is known about the importance of py rodiversity for individual species. The availability of diverse post-fire habitats may be key for fire-associated species if they require different resources at different life-history stages. 2. We tested for age-specific habitat relationships in the black-backed woodpecker, a post-fire specialist. We used radio-telemetry to track fledgling and adult wood peckers in burned forests and built resource selection functions to compare the effect of stand-, tree- and snag-level covariates between adults and fledglings. 3. Fledgling black-backed woodpeckers selected habitat with more live trees than adults and used more heterogeneous habitats burned at lower severity, illustrat ing strong age-dependent effects on habitat selection. Within selected stands, fledglings were less likely to use snags and more likely to use live trees when com pared to adults, but both age classes showed strong positive selection for larger-diameter trees (live and dead).
