在潮湿的热带地区之外，非生物因素通常被认为是分解的主要调节因素，在预测分解率时往往不考虑生物的影响。在这项研究中，我研究了博茨瓦纳北方高度季节性半干旱奥卡万戈三角洲地区五个陆地栖息地中白蚁群落组成和丰度对本土物种（Croton megalobotrys）木材枯枝落叶分解的影响，以确定分解者群落组成和丰度的自然变化是否影响分解率。我在两个地区进行了研究，Xudum和Santawani，Xudum研究在Santawani研究之前。我评估白蚁组合的组成和丰度使用网格的调查诱饵（卫生纸卷）放置在土壤表面和检查2-4次/月。我在每个调查诱饵旁边放了一个小块（一段木屑），并通过平均小块的质量损失来测量分解情况。腐烂...
Outside of the humid tropics, abiotic factors are generally considered the dominant regulators of decomposition, and biotic influences are frequently not considered in predicting decomposition rates. In this study, I examined the effect of termite assemblage composition and abundance on decomposition of wood litter of an indigenous species (Croton megalobotrys) in five terrestrial habitats of the highly seasonal semiarid Okavango Delta region of northern Botswana, to determine whether natural variation in decomposer community composition and abundance influences decomposition rates. I conducted the study in two areas, Xudum and Santawani, with the Xudum study preceding the Santawani study. I assessed termite assemblage composition and abundance using a grid of survey baits (rolls of toilet paper) placed on the soil surface and checked 2–4 times/month. I placed a billet (a section of wood litter) next to each survey bait and measured decomposition in a plot by averaging the mass loss of its billets. Decomp...
