Insects are ubiquitous and are found all over the world, in the Lithosphere, Hydrosphere and Biosphere. According to evidences insects appeared on this planet Earth some 440 million years ago, long before the appearance of man in this world. Because of their dynamic adaptational traits insects have escaped extinction all these years. Insects have the innate ability to adapt themselves to any kind of adverse environmental conditions. The morphology and anatomy of insects, as well as their mode of life are quite important factors that help in the development of traits for adaptation. In this book the authors have given a detailed account of the general aspects of insects, as well as morphology and anatomy of insects. Studies on such aspects about insects are ultimately aimed at devising and adopting physical, mechanical, chemical or biological control measures to combat the insects, which have turned into pests and pose a serious problem to mankind. The text is substantiated with many fine, hand-drawn figures that will help better understanding of the book and make the reading more interesting.

Raising of Quality planting material is important primary input for productive forestry and for any afforestation program. Mitigation of climate change and carbon credit schemes have increased the scope of this subject. Large quantities of seed are needed every year to raise the nursery stock for propagating the desired plant species. A plentiful supply of quality seed i.e., high in viability and vigour, is therefore one of the prerequisites to make such activities successful. Nursery raising of both conifers and broadleaved becomes important for sustaining life in temperate Himalayan region and to conserve and also a means to distribute the plant germplasm. QPM is essential input in forestry for maximizing revenues, improving adaptability to adverse environmental conditions and meeting quality raw material requirements of markets. Guaranteed performance in terms of higher yield and quality of crops could be achieved with reliable planting material and good management practices. The agroforestry (TOF) in the country is mostly practiced on private farmlands, community lands and on government wastelands. In view of the increasing importance of quality planting material in forestry and the numerous challenges in handling, testing and storage of forest seed, present volume is very important for the benefit of forest seed/nursery industry.

Rain forests represent the world's richest repository of terrestrial biodiversity, and play a major role in regulating the global climate. They support the livelihoods of a substantial proportion of the world's population and are the source of many internationally traded commodities. They remain (despite decades of conservation attention) increasingly vulnerable to degradation and clearance, with profound though often uncertain future costs to global society. Understanding the ecology of these diverse biomes, and peoples'dependencies on them, is fundamental to their future management and conservation. Tropical Rain Forest Ecology, Diversity, and Conservation introduces and explores what rain forests are, how they arose, what they contain, how they function, and how humans use and impact them. The book starts by introducing the variety of rain forest plants, fungi, microorganisms, and animals, emphasising the spectacular diversity that is the motivation for their conservation. The central chapters describe the origins of rain forest communities, the variety of rain forest formations, and their ecology and dynamics. The challenge of explaining the species richness of rain forest communities lies at the heart of ecological theory, and forms a common theme throughout. The book's final section considers historical and current interactions of humans and rain forests. It explores biodiversity conservation as well as livelihood security for the many communities that are dependent on rain forests - inextricable issues that represent urgent priorities for scientists, conservationists, and policy makers.

Lack of clean water, inadequate sanitation, and insufficient infection prevention and control promote the spread of parasites. The discovery of antiparasitic drugs was considered a milestone in the veterinary and medical sciences, but their use has subsequently become limited due to the emergence of resistance. While plenty of attention has been given in human and animal health communities to the global threat of antimicrobial drug resistance, specific antiparasitic advice is less available. This book provides an in-depth view of the issue for parasitologists, pharmacologists and veterinary scientists. Specifically discussing antiparasitic drug resistance mechanisms and factors responsible for the problem, it covers: The physiological basis of parasitism; Resistance across protozoa, helminths, insects, mites and ticks; Molecular and phenotypic diagnostic methods; Practical strategies for mitigating resistance development. While it is clear that the veterinary field urgently requires the development of new antiparasitic drugs, of equal or even increased importance is the evaluation of alternative therapies and formulation of stringent policies to ensure appropriate drug use in veterinary practice. Highlighting the importance and development of resistance across different parasite groups, this book covers factors responsible for resistance development and advises strategies for effective stewardship and resistance mitigation.

This book presents the latest findings in medical entomology in Japan and neighboring Asian countries. It provides an overview of the current issues of medically important arthropods in this region and also refers to the issues that are likely to become more serious in the near future. It helps us understand that addressing the arthropod issues is not enough in limited regions, but requires a coordinated response throughout these regions. Global warming and globalization are affecting both vector and vector-borne diseases, causing rapid changes in their distribution and ecology. From the perspective of global pest control, the book focuses not only on domestic pests in Japan but also on pests in neighboring Asian countries including the Philippines, Thailand, Taiwan, Vietnam, etc., which are geographically and economically close to Japan. Japan has experience of eradicating malaria and lymphatic filariasis, drastically reducing the number of cases of Japanese encephalitis patients, and succeeded in controlling flies in the metropolis of Tokyo. The know-how learned and created from these past successes should provide valuable information for other parts of Asia that are still struggling with pest infestation today. With the growing interest in these issues worldwide, this book provides essential information in medical entomology for researchers, including students and early career researchers. By integrating the latest findings in medical entomology with past successes and experiences in the field, the book is also a valuable reference for many professionals planning sustainable pest control.

This volume focuses on the history of research on hearing from comparative approaches. Each chapters examines the most formative studies that led to current understanding of hearing across taxa and still influence hearing research in general. Much of the early work on hearing, which goes back to Aristotle, as well as the classic work of 16th to early 20th century scientists (e.g., Spellanzani, Retzius, Ramón y Cajal, and Helmholtz) is not well known to modern investigators. Similarly, work in the first 75 years of the 20th century is also unknown or, in some cases, dismissed because it is “old.” Much of the earlier work describes research approaches and results fundamental to our understanding of hearing as well as the beauty of observation and synthesis. The pioneering work on hearing contains ideas and questions that are still germane today. Thus, the goal of this volume isto introduce, review, and put into perspective, older but exemplary, extraordinary studies by investigators that form the basis of our knowledge as well as questions being asked today.Each chapter includes the first significant observations and approaches to hearing in the taxa and/or hearing type that is the focus of the chapter with some of the most important earlier papers discussed in some detail, including the theories, formative experiments, results, and conclusions. Each chapter provides briefer notations and citations of additional important papers that are outgrowths of the founding research – or correlate and even reverse the original works. This volume is a departure from the classic approach established for the SHAR books in which the focus has been on a single topic, and on the most recent and exciting discoveries. One difference in this volume from past SHAR volumes is that we have a more coordinated approach for the chapters to ensure that this volume is, indeed, a documentation of hearing research history, not a review of the latest status of the topic. A second difference is that the focus of the volume is on the historical value of studies. In that sense, the volume maintains the tutorial value for which SHAR books are famous, but it explores the ancestry of modern research in order to help new researchers to gain perspective on important questions and on fundamental information they may not fully appreciate – to their loss. Our interest in doing this volume comes from phenomena familiar to most senior investigators - that younger investigators often have little or no sense of the history of their discipline, and they often do not know that their “hot” new idea was not only pursued, and often solved, but further that it was solved in an elegant way. We believe it is important to bring the methodologies and discoveries on hearing done before the advent of the internet to light, for the benefit and growth of new research.In deciding on the chapter divisions for this book, we considered a number of different organizational schemes, and particularly using as a focus methodological approaches (e.g., psychoacoustics, low to high frequency types, physiology, anatomy). However, we came to the conclusion that most investigators tend to be more focused on working within a particular taxonomic group, settling on particular taxa, in many cases driven by the special hearing abilities. We also concluded that that this approach is more naturally related to the evolution not only of hearing, but also to the evolution of ideas, as much of hearing science was part of the “natural philosopher” approach that was a core element of historical discoveries.
