(1)夏季在南非和英国采集了树木中无脊椎动物区系的比较击倒样本。在这两个国家采集了垂枝桦、栎、刺槐、醉鱼草和柳属物种的样本;仅在南非采集了刺桐样本。(2)总共有41844个个体被分类和鉴定;其中只有两个是软体动物，其余的是节肢动物。(3)乔木行业协会的组成进行了分析方面的家庭，物种和个人的数量和比例，并通过生物量。(4)树木节肢动物区系的分类学相似性在国家内部和国家之间进行比较。(5)窄叶软茎柳树（柳属物种）的动物区系和植食性物种比阔叶树采样。(6)在这两个国家的所有树木上记录的捕食性物种的比例有一个惊人的一致性，在不同的阔叶树上也有一个恒定的植食性物种的比例。咀嚼和吸汁物种的相对数量是高度可变的，但当总结导致比例均匀的植食性物种的数量。这些现象进行了讨论，在最近的辩论模式的社区结构。
(1) Comparative knockdown samples of the invertebrate fauna in trees were taken during summer in South Africa and in Britain. Betula pendula, Quercus robur, Robinia pseudoacacia, Buddleia and Salix species were sampled in both countries; Erythrina caffra was sampled in South Africa only. (2) A total of 41 844 individuals were sorted and identified; only two of these were molluscs, the rest arthropods. (3) The composition of the arboreal guilds is analysed with respect to the numbers and proportions of families, species and individuals, and by biomass. (4) Taxonomic similarities in the arthropod faunas of trees are compared within and across countries. (5) The narrow-leaved flexible-stemmed, willows (Salix species) had a depauparate fauna and proportionately more phytophagous species than the broad-leaved trees sampled. (6) There was a striking uniformity in the proportion of predatory species recorded on all trees in both countries, and also a constant proportion of phytophagous species on different broad-leaved trees. The relative numbers of chewing and sap-sucking species were highly variable, but when summed resulted in proportionally uniform numbers of phytophagous species. These phenomena are discussed in the light of recent debate on patterns in community structure.
