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
The analysis of tree-ring patterns, or dendrochronology, is a very exact science and an important dating technique. The basis of the method is misleadingly simple: that overlap of successive older ring patterns can generate a master chronology and samples of unknown age can then be checked against this. This book, published originally in 1982, traces the development of a specific project from its inception to the successful completion of some of the longest chronologies in Europe. In doing so it looks at some of the problems associated with the subject and at the levels of precision possible. After outlining the techniques associated with the measurement and processing of tree-ring patterns, the author traces an attempt to construct such an independent chronology in a new area. The book breaks naturally into sections conditioned by the availability of timbers and these can be listed as modern, late medieval, medieval, early medieval and prehistoric. As far as possible the results are presented in the order in which things happened, thus preserving the sense of a developing subject.

Book Description
Urban Ecology is a rapidly growing field of academic and practical significance. Urban ecologists have published several conference proceedings and regularly contribute to the ecological, architectural, planning, and geography literature. However, important papers in the field that set the foundation for the discipline and illustrate modern approaches from a variety of perspectives and regions of the world have not been collected in a single, accessible book. Foundations of Urban Ecology does this by reprinting important European and American publications, filling gaps in the published literature with a few, targeted original works, and translating key works originally published in German. This edited volume will provide students and professionals with a rich background in all facets of urban ecology. The editors emphasize the drivers, patterns, processes and effects of human settlement. The papers they synthesize provide readers with a broad understanding of the local and global aspects of settlement through traditional natural and social science lenses. This interdisciplinary vision gives the reader a comprehensive view of the urban ecosystem by introducing drivers, patterns, processes and effects of human settlements and the relationships between humans and other animals, plants, ecosystem processes, and abiotic conditions. The reader learns how human institutions, health, and preferences influence, and are influenced by, the others members of their shared urban ecosystem.

Book Description
Pests cause economic damage to crops and stored products, while vectors are responsible for the transmission of disease-causing agents in human beings and livestock. Although the application of synthetic pesticides in agriculture has given immediate relief, it has also caused well-known side effects, leading to a general consensus among entomologists and agriculturists to shift towards other ecofriendly pest management. Insect natural enemies consisting of predators, parasitoids, and pathogens have attracted the attention of scientists across the globe. These natural enemies exist in agroecosystems and suppress the populations of pests. Parasitoids are farmers’ friends and the most successful group of natural enemies. Highly specialised in their host choice, the female parasitoid searches for a suitable host to lay eggs and larvae in, on or near the hosts. Exploiting this potency of parasitoids may yield successful results in controlling notorious pests in an ecofriendly way. This book covers information on the important biocontrol agents effective in pest suppression. It starts with insect parasitic groups followed by specific groups of parasitoids. It is hoped that the book presents a comprehensive account of beneficial parasitoirds, and will be useful to undergraduate and postgraduate students of Entomology, Biological Control, Plant Protection, Agricultural Zoology, and Zoology, besides those involved in competitive examinations and policy planning. Features: Each chapter has been written by very experienced specialists Every chapter includes Learning Objectives and Points to Remember This book offers comprehensive knowledge of parasitoids and their application in pest management in a rational way

Book Description
This book is intended as a textbook for 3rd year undergraduate students, as well as postgraduate students. It comprises a review of the current opinion regarding the evolution and adaptation of terrestrial arthropods, beginning with the paleontological, embryological, morphological and physiological evidence. The implication of size is then considered in relation to life on land. A discussion of insect phylogeny and the origin of flight is followed by an account of evolutionary trends in reproduction. Further chapters cover adaptations to extreme environments, dispersal and migration, defensive mechanisms and, finally, present arguments for the success of the terrestrial arthropods in general.
