The palatability of common plants from three stages of secondary sere have been assessed by a bioassay method. Foliage was exposed to five taxonomically very different herbivores (Agriolimax, Schistocera, Spodoptera, Myzus and Trialeurodes). Palatability was measured by foliage consumption or, for sap suckers, by survival and reporduction. The results of these experiments supported the predictions of Feeny's 'Apparency theory', but indicated considerable variations in palatability within plant communities and between herbivores.
通过生物测定法评估了次生演替三个阶段常见植物的适口性。将叶子暴露于五种分类学上差异很大的食草动物（蛞蝓、沙漠蝗、草地贪夜蛾、桃蚜和粉虱）。适口性通过叶子消耗量来衡量，对于吸食汁液的昆虫，则通过存活率和繁殖率来衡量。这些实验的结果支持了费尼“明显度理论”的预测，但表明植物群落内部和食草动物之间的适口性存在相当大的差异。
