Insect Conservation Biology (Conservation Biology, No 2)Insects are the major component of the world's biodiversity. By their vast numbers of both species and individuals, they are vital determinants of the terrestrial ecological processes. Quantitatively, insects are important pointers for the species-rich geographical areas. Qualitatively, they are also important, whether the subjects of conservation themselves or as tools for identifying biotic areas with high endemism. |
