摘要

本研究首次对加纳Shai Hills资源保护区火灾后的昆虫群落进行了系统评价。采用时间序列方法，从一个未燃烧和三个燃烧的热带稀树草原样地（火灾后6个月、12个月和18个月）取样昆虫群落。昆虫丰富度和丰度随火灾发生时间的增加而增加，但仍低于未燃烧对照。不同的分类群对火灾的反应不同：蚁科对火灾表现出恢复力，而蚁科和蚁科在所有被烧毁的地块上都没有恢复力。群落组成逐渐向未燃控制方向转变。研究结果强调了火灾的生态影响以及火灾易发草原生物多样性管理的重要性。

Rapid Assessment of Insect Responses Post-Fire Chronosequence in Equal-Sized Savanna Grassland Plots

This study presents the first systematic assessment of insect communities following fire disturbance in Ghana's Shai Hills Resource Reserve. Using a chronosequence approach, insect assemblages were sampled from one unburnt and three burnt savanna plots (6-, 12-, and 18-month post-fire). Insect richness and abundance increased with time since fire, but remained lower than in the unburnt control. Taxa responded differently: Formicidae showed resilience to fires, while Phasmatodea and Mantodea were absent from all burnt plots. Community composition gradually shifted toward the unburnt control. Findings highlight the ecological impacts of fire and the importance of replication in managing biodiversity in fire-prone grasslands.
