Book Description
Rapid depletion and degradation of species in diverse ecosystems and the implications of this for human welfare have the cause for increasing concern. Biodiversity or variability among living organisms and the ecological complexes of which they are a part, is essential for ensuring the basic ecological services and resources necessary for sustaining human welfare. The loss of biodiversity is therefore, considered one of the most serious problem threatening the world today. An understanding of the ecological implications of the increasing loss of bodiversity, not to mention of the economic implications, has therefore, became vital. A biodiversity loss is irreversible. A calls for increased caution in our efforts to convert and exploit natural resources. Some minimal level of biodiversity is necessary to main ecological functioning, which in turn is necessary for generating the biological resources on which human welfare depends. Needless to emphasive that substantial biodiversity loss occurs due to forest clearing and degradation, leading to the need for assessing biodiversity in different ecosystems. Keeping these aspects in mind, the present volume highlights biodiversity in different cropping systems besides that the impact of cold and hot deserts. Selection of the topics in the various chapters is essentially because of the experience of the authors in the field of biodiversity.

Book Description
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 Description
In this book, 'state of art' situation in patterns of behaviour is presented by the authors, each with expertise in respective fields on diverse aspects such as pollination, predation and parasitism, forest and agricultural pests, besides the dynamics of aquatic insects in general and dragonflies in particular, in addition to insect vectors of diseases. The need for an appreciation of the differentiation processes controlling growth and development of plant galls has been adequately emphasised, these galls representing highly regulated growth manifestations of plants, ensuring nutrition and shelter for the insects concerned. Behavioural shifts of insects due to current climatic changes and their implications in insect conservation and control are also highlighted. This book will be relevant to the undergraduate and particularly graduate students taking courses in insect ecology and evolution, conservation biology and environmental management as well as to committed researchers in these fields in addition to conservation practitioners eager to have a comprehensive background of the multifaceted aspects of insect behavioural dynamics.

Book Description
Insects are a dominant component of biodiversity in terrestrial ecosystems and play a key role in mediating the relationship between plants and ecosystem processes. This volume examines their effects on ecosystem functioning, focusing mainly, but not exclusively, on herbivorous insects. Renowned authors with extensive experience in the field of plant-insect interactions, contribute to the volume using examples from their own work.

Book Description
One of the world's most insightful writers on the subject brings together an array of important and readable information on the ways in which insects and plants coexist in nature. Interrelationship Between Insects and Plants is a rare and expansive look at the intertwining of these two vastly different species. Its aim is to summarize in a simple and understandable way the basis of food selection among insects, and to review the various sides of their relationships with plants.

Book Description
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.

Book Description
The 11th International Symposium on Insect-Plant Relationships (SIP11), held on August 4-10, 2001, in Helsingør, Denmark, followed the tradition of previous SIP meetings and covered topics of different levels from chemistry, physiology, and ethology to ecology, genetics, and evolution of insect-plant relationships. The present volume includes a representative selection of fully refereed papers as well as a complete list of all the contributions which were presented at the meeting. Reviews of selected topics as well as original experimental data are included. The book provides valuable information for students and research workers interested in chemical and biological aspects of interactions between individuals and populations of different organisms.

Book Description
The beauty and grace of butterflies have long captivated people around the world, but their diversity and complexity have drawn the special attention of amateur and professional scientists since at least the time of Darwin. Thanks to this long history of research, more is known about butterflies than is known about almost any other group of insects. experts synthesize current knowledge of butterflies to show how the study of these fascinating creatures as model systems can lead to deeper understanding of ecological and evolutionary patterns and processes in general. The 26 chapters are organized into broad functional areas, covering the uses of butterflies in the study of behaviour, ecology, genetics and evolution, systematics, and conservation biology. Especially in the context of the current biodiversity crisis, this book shows how results found with butterflies can help us understand large, rapid changes in the world we share with them - for example, geographic distributions of some butterflies have begun to shift in response to global warming, giving early evidence of climate change that scientists, politicians and citizens alike should heed. Butterflies: Ecology and Evolution Taking Flight offers students, scientists and amateur naturalists a concise overview of the latest developments in the field. Furthermore, it articulates an exciting new perspective of the whole group of approximately 15,000 species of butterflies as a comprehensive model system for all the sciences concerned with biodiversity and its preservation.
