Fire is a natural disturbance that occurs in many temperate and tropical ecosystems worldwide. As ubiquitous members of these ecosystems, spiders (Araneae) are often affected by fire, and their response to this disturbance has been shown to be dependent on taxonomy, functional diversity, seasonality, and a variety of environmental factors. We examined the effect of fire on ground-dwelling spider assemblages in temperate forests in central Indiana over 5 yr and found that spider assemblages were significantly affected by fire disturbance. Overall spider abundance decreased, whereas species richness and diversity remained unaffected. We also found that spider response depended heavily on the family and/or guild to which the spider belonged. We suspect that altered habitat heterogeneity, the patchy nature of fire’s effect on leaf litter, and the high rate of recolonization by spiders all played important roles in these observed patterns.

火灾对印第安纳州中部森林地栖蜘蛛（蜘蛛纲）组合的影响

火灾是一种自然干扰，发生在全球许多温带和热带生态系统中。作为这些生态系统中无处不在的成员，蜘蛛 (Araneae) 经常受到火灾的影响，它们对这种干扰的反应已被证明取决于分类学、功能多样性、季节性和各种环境因素。我们在 5 年多的时间里检查了火灾对印第安纳州中部温带森林中地面蜘蛛群的影响，发现蜘蛛群受到火灾干扰的显着影响。总体蜘蛛丰度下降，而物种丰富度和多样性不受影响。我们还发现蜘蛛的反应在很大程度上取决于蜘蛛所属的家庭和/或行会。我们怀疑生境异质性的改变，火灾对落叶的影响的斑驳性质，
