Volume One of the thoroughly revised and updated guide to the study of biodiversity in insects The second edition of Insect Biodiversity: Science and Society brings together in one comprehensive text contributions from leading scientific experts to assess the influence insects have on humankind and the earth’s fragile ecosystems. Revised and updated, this new edition includes information on the number of substantial changes to entomology and the study of biodiversity. It includes current research on insect groups, classification, regional diversity, and a wide range of concepts and developing methodologies. The authors examine why insect biodiversity matters and how the rapid evolution of ...
A revision and the first phylogenetic analysis of the widely distributed plant bug genus Tytthus is presented. All 24 species of this genus, including five described as new, prey exclusively on planthopper (Delphacidae) eggs, making them of great importance on agricultural monocots. Two species have been used successfully in biocontrol programs to suppress populations of sugarcane delphacid on sugarcane and brown planthopper on rice. All species of Tytthus are relatively small, but the tiny brachypterous males of one species, ranging from 1.08?1.30 mm long, rank it as possibly the world?s smallest known plant bug. Members of this genus are found in nearly all biogeographic regions, including 18 restricted to the Nearctic and Neotropics and three from the eastern Oriental and Indo-Pacific regions. There are also two Holarctic and one circumtropical (Afrotropical, Neotropical, and Oriental) species. A hypothesized relationship with several Nearctic plant bug genera suggests a New World origin for this group of important predatory bugs.
The Organic Chemistry of Palladium, Volume 1: Metal Complexes deals with the number of organic reactions that can be catalyzed by palladium, particularly as regards the structures bonding, and reactions of the metal complexes. The book discusses monodentate ligands which are either neutral (carbonyls, isonitriles, carbenes) or anionic (methyl, phenyl, ethynyl, hydride). The text also examines the complexes formed by 1,3-. 1,4-, and 1,5-diolefins where four carbon atoms are bound to the metal. Palladium (II) can undergo a reaction with the 1,3-dienes and results in a ?-allylic complexes where only three carbon atoms are coordinated to the metal. (The bonding situation in complexes 1,4- and 1,...
True bugs (Heteroptera) are a diverse and complex group of plant-feeding and predatory insects important to food production, human health, the global economy and the environment. Within the nearly 43,000 species described around the world, Neotropical true bugs are particularly diverse, and much remains to be discovered about their biology and relations with other species. Inspired by the need for a comprehensive assessment, True Bugs (Heteroptera) of the Neotropics is the most complete and thorough review ever published. Experts in each of the seven infraorders have drawn together the scattered literature to provide detailed treatments of each major taxon. The most common and important spec...
