Phytophages occur in the forest, however, their proportion in the species pool is low, whereas a high percentage of Central European parasitoids is represented in the local pool..A set of hypotheses is discussed that might explain high

Plant Diversity in Successional Grasslands: How is it Modified by Foliar Insect Herbivory?tive balance of direct and indirect effects of herbivory are likely to change. However, this involves a major assumption, namely that the herbivores remain the same. While this may be true for vertebrate herbivores, especially when used in management, it is far from true for the smaller invertebrate

Thus, the presence of lemur species gives some information about habitat quality, however, the absence of the same species may not be related to present forest characteristics but be based on habitat charac
