Diet composition and body size in insect herbivores: Why do small species prefer young leaves?

Popis výsledku v původním jazyce

The hypothesis that small body size is correlated with preference for young leaves was tested in a community of leafchewing insect herbivores feeding on Ficus wassa in a humid tropical forest in Papua New Guinea. Feeding experiments revealed a negative correlation between body size and a preference for young leaves. While small species preferred young leaves, large species showed no preferences, or preferred young leaves only slightly. This relationship was found for the entire leaf-chewing community, as well as for many of the constituent taxa on several taxonomic levels, from orders to genera. Taxonomic position of a species played little role in determining its preferences. It is proposed that higher toughness and lower nutrient content may act as complementary defences, which prevent small insects from feeding on mature foliage.
