在喀麦隆南部Mbalmayo森林保护区，利用100米带样带对白蚁进行了5个不同干扰程度的森林样地的定性采样。结果表明：与近原生地相比，受干扰严重的2个再生地物种丰富度显著降低，受干扰较小的2个再生地物种丰富度差异不大；有证据表明，更新样地的物种丰富度略有增加。在原始区和再生区，取食土壤的植物占主导地位，而在受严重干扰的样地，取食土壤的植物数量大大减少。木食动物似乎比土食动物对干扰的适应能力更强，尽管在最受干扰的样地，它们的物种丰富度较低。近初生地以白蚁科为优势类群，较少受干扰的再生地以顶蚁科为优势类群，空旷区以巨蚁科为优势类群。热带稀树草原相关物种似乎没有二次入侵样地，受干扰较少的再生样地物种丰富度的小幅明显增加似乎是由于通常与自然林隙相关的森林物种的涌入。
Five forest plots of differing disturbance levels were sampled qualitatively for termites in the Mbalmayo Forest Reserve, southern Cameroon, using 100 m belt transects. Results showed a large reduction in species richness in two severely disturbed plots compared with a Near Primary plot, but little difference in two less disturbed regenerating plots; there is some evidence for a slight increase in species richness in the regenerating plots. Soil-feeders predominate in the primary and regenerating plots, but are greatly reduced in the severely disturbed plots. Wood-feeders appear to be more resilient to disturbance than soil-feeders, although their species richness is low in the most disturbed plots. The Termitinae are the dominant taxonomic group in the Near Primary plot, the Apicotermitinae in the less disturbed regenerating plots and the Macrotermitinae in the clear felled areas. There appears to be no secondary invasion of plots by savanna-associated species, and the small apparent increase in species richness in the less disturbed regenerating plots appears to be due to the influx of forest species usually associated with natural gaps.
