通过在 9 个地点的 45 个（10 m × 300 m）样地中计数和识别这些属物种的所有高于 30 cm 的个体，评估了低地龙脑香林中 Macaranga 和 Mallotus 物种（大戟科）不同类型干扰的指标值（IV）。发现了 12 种 Macaranga 和 9 种 Mallotus。主要森林干扰类型（原生林、次生林、选择性采伐林、一次烧毁林、反复烧毁轮耕林）各有一套指示物种。通过测量九个森林结构参数来评估森林类型的干扰程度。 Macaranga 和 Mallotus 物种的出现与森林中的干扰程度密切相关。大多数 Macaranga 物种具有高干扰水平的特征，而大多数 Mallotus 物种更喜欢中度至低水平的干扰。然而，两个属都有处于两种干扰极端的物种。使用多元回归分析，形成了 Macaranga 和 Mallotus 物种的组合，并用于预测单独的森林结构参数和森林干扰的总体水平。 Macaranga 和 Mallotus 物种可分为 (1) 原始森林“残余”物种； (2) 通才先驱种； (3)高干扰先锋种。
The indicator value (IV) of Macaranga and Mallotus species (Euphorbiaceae) for different types of disturbance in lowland dipterocarp forest was assessed by counting and identifying all individuals of species of these genera taller than 30cm in 45 (10 m ×300 m) plots at nine locations. Twelve Macaranga and nine Mallotus species were found. The main forest disturbance types (primary forest, secondary forest, selectively logged forest, forest burned once, and repeatedly burned forest used for shifting-cultivation) each had their own set of indicator species. The level of disturbance in the forest types was assessed by measuring nine forest structural parameters. The occurrence of Macaranga and Mallotus species was closely related to the level of disturbance in a forest. Most Macaranga species were characteristic of high disturbance levels, while most Mallotus species preferred intermediate to low levels of disturbance. However, both genera had species at both disturbance extremes. Using multiple regression analysis, combinations of Macaranga and Mallotus species were formed and used to predict the separate forest structural parameters and the general level of disturbance of a forest. The Macaranga and Mallotus species could be grouped into (1) primary forest ‘remnant’ species; (2) generalist pioneer species; and (3) high disturbance pioneer species.
