Book excerpt: One of the principal aims in writing this book pertains to the increasing impact of human influence on natural habitats in recent years, more notably to the loss of habitat quality. Increased urbanization, considerable reduction in natural forest areas, changing ecology of fresh water ecosystems, lakes and wet lands, besides changing microhabitats, have had their impact on insect populations. A wide range of responses exist among several species of insects living in these changing environments, more especially landscape dynamics creating a shifting mosaic of habitats. Sudden changes in the extent or quality of habitat tend to influence the behaviour, reproduction and survival of individuals. In very rare cases the existence of a particular species depends on the presence of some other species, not to mention of the extinction of food chains. As such, a basic understanding of the nature of habitat loss and fragmentation and their impact on insect species dynamics become important. Numerous questions are raised about patterns and timing of the evolution of insect-plant association which are essential for an understanding as to ``why the world is the world as it is today''. In this effort several specialists on diverse aspects have generously rendered assistance through providing literature and photographs and while appreciating their generosity, we would like to thank them individually for all the assistance rendered without which the production of this volume would be impossible.

Available in PDF, EPUB and Kindle. Book excerpt: The dominance of insects amongst all living organisms on earth, coupled with infinite wealth of knowledge so important for our own existence, is a fundamental scientific fact which is yet to be widely acknowledged. This dominance means that in numbers of species beyond our comprehension these animals permeate diverse and essential natural processes in Earth's terrestrial, aerial and freshwater ecosystems, contributing to the function of the natural world as a self-sustaining biological system. Invariably insects are an integral and complex part of the terrestrial and freshwater ecosystems with which the future of humans is inextricably linked. Insects have ultimately achieved a formidable diversity. Generally, insects are beneficial organisms, however, many of them are important pests and/or vectors to a large number of parasites and other microbial pathogens to both human being, his associates and the plants. The burden caused by their infestation or infection run up to several million-zillion rupees annually. Therefore, knowledge about extreme biodiversity and ecological relationships of these animals is a practical necessity: in the man's own interest to sustain the species. Packed with original 25 original articles/reviews, this book on 'Entomology: Ecology and Biodiversity' offers an invaluable opportunity to comprehend more deeply about our most intimate allies - the insects! The book truly establishes a foundation in basic entomology through varied and diverse treatment to entomology, while focusing on specialized topics in insect ecology and biodiversity, forensic and medical entomology.

Available in PDF, EPUB and Kindle. Book excerpt: This book aims at an understanding of diverse mutualistic interactions, with all individuals tending to display their own adaptational ranges. In view of different species using different kinds of microhabitats, the diversity of assemblages goes a long way towards a better appreciation of the adaptive trends of the species involved therein. Insect assemblages and communities are shaped by the compositional, structural and trophic interactions which hold together ecological communities.

Book excerpt: Aquatic insects are the dominant invertebrate fauna in most freshwater ecosystems, and figure prominently in the work of a diverse range of researchers, students, and environmental managers. Often employed as indicators of ecosystem health, aquatic insects are also commonly used as model systems to test hypotheses in ecological topics including metapopulation and metacommunity dynamics, recruitment limitation, trophic interactions, and trophic networks. Due to their complex life cycles, aquatic insects must master both terrestrial and aquatic environments, crossing these ecosystem boundaries during different stages of development and reproduction. In this wide-ranging text, life under and on top of the water surface are covered in unusual detail, including the biomechanics of life in water, locomotion underwater and on surface films, gas exchange, physico-chemical stressors, feeding, sensory perception and communication, reproduction, egg-laying and development, and the evolution of aquatic habits. The threatened status of freshwaters around the world, coupled with an expanding population of researchers and managers charged with their well-being, signals the importance of such a book as many individuals seek to understand how insects function in these often challenging physical environments. Interest in freshwaters may never have been higher with ever-increasing conflict between water allocation for human (agricultural) use and conservation. Aquatic Entomology is suitable for graduate students, researchers, and managers interested in the subject from a perspective of either basic or applied ecology. It will also be a valuable supplementary text for courses in limnology or freshwater ecology, entomology, and water resource management.

Book excerpt: Of how many books can it be said that their publication directly affected the personal wellbeing of every person on the earth? No doubt, many books have been written which have changed the outlook of millions, altered social institutions, and even deflected the course of history, but of very few can it be said that their contents concerned the very central core of the construction of that rare amongst rarest of human morphs – the scientist – whom the entire humanity owes virtually everything, from good living conditions including clothes, drinking water, food, hygiene and health to clean environment. This book is all about the virtues that make a scientist. It is certainly not an easy task to define a scientist but for the characteristic that he is maddeningly obsessed with the prospects of achieving his objective under the severest of personal and professional stumbling blocks! Beforehand, thus, he visualises the entire scenario of his undertakings without actually physically seeing & that is what makes him different from a man of ordinary mould: Wise haveth their eyes, in the head; Fools waketh through forest, & see no firewood! I hope that this book, unique in its approach and treatment on the subject, and written with a view to ignite the young minds to develop habits of perseverance and dedication, so that a stronger future of India could be constructed.
