Book Description
From the Arctic to South Africa - one finds them everywhere: Ants. Making up nearly 15% of the entire terrestrial animal biomass, ants are impressive not only in quantitative terms, they also fascinate by their highly organized and complex social system. Their caste system, the division of labor, the origin of altruistic behavior and the complex forms of chemical communication makes them the most interesting group of social organisms and the main subject for sociobiologists. Not least is their ecological importance: Ants are the premier soil turners, channelers of energy and dominatrices of the insect fauna. TOC:The importance of ants.- Classification and origins.- The colony life cycle.- Altruism and the origin of the worker caste.- Colony odor and kin recognition.- Queen numbers and domination.- Communication.- Caste and division of labor.- Social homeostasis and flexibility.- Foraging and territorial strategies.- The organization of species communities.- Symbioses among ant species.- Symbioses with other animals.- Interaction with plants.- The specialized predators.- The army ants.- The fungus growers.- The harvesters.- The weaver ants.- Collecting and culturing ants.- Glossary.- Bibliography.- Index.

Book Description
This monumental reference work treats an entire worldwide order of insects. It summarizes, from both a biological and sytematic perspective, current knowledge on the Heteroptera, or true bugs, a group containing approximately 35,000 species, many of which are important to agriculture and public health. To introduce the reader to this group, Randall T. Schuh and James A. Slater offer chapters on the history of the study of the Heteroptera, research techniques, and sources of specimens. They also cover attributes of general biological interest, including habitats, habits, mimicry, and wing polymorphism; selected taxa of economic importance; and basic morphology.Presenting a current classification of the Heteroptera, the authors synthesize to the subfamily and sometimes tribal level the enormous, scattered literature, including diagnoses, keys, general natural history, a summary of distributions, and a listing of important faunistic works. In addition to a wealth of detailed illustrations, they provide a glossary to help the reader deal with the confusing terminology that has evolved over the years, as well as an extensive bibliography of more than 1350 entries.Meticulously prepared by two of the world's leading specialists, this major work will be the standard reference on the Heteroptera for many years to come.

Book Description
This issue of Journal of Insect Conservation is the first to be dedicated entirely to beetles. It contains a number of papers to demonstrate the variety and scope of problems and conservation concerns that surround these insects. A short introductory perspective is followed by eight original contributions, in which beetles from many parts of the world are considered, and in which some major threats to their wellbeing are evaluated.

Book Description
There have been at least ten English-language textbooks of palaeobotany since D. H. Scott published the first edition of Studies inFossilBotany in 1900. Most have been written by scientists who were primarily botanists by training, and were aimed largely at a readership familiar with living plants. They tended to follow a general pattern of an introductory chapter on preservation of plants as fossils, followed by a systematic treatment, group by group. Only Seward in his Plant Life Through the Ages departed from this pattern in presenting a chronological sequence. In the present book, Meyen breaks with?is tradition. Although having a basically biological approach, he reaches out into all aspects of the history of plant life and the wider implication of its study. Only half of the present work deals sequentially with fossil plant groups, treated systematically. The remainder then explores those topics which most other textbooks have incidentally??e generally either ignored or have only mentioned rather problems of naming and classifying fragmentary plant fossils, their ecology; biogeography and palaeoclimatic significance and the contribution that?ey have made to the understanding of living plant morphology, and of the process of evolution.
