Book Description
Zoology is a branch of biology that studies the animal kingdom. This encompasses the study of structure, classification, embryology, habit and distribution of animals, whether extinct or living, and their interactions with their environment. Structural studies in zoology are approached from the domains of cell biology and anatomy. This enables the study of unicellular and multicellular organisms from the perspective of the structure and function of cells, organs and organ systems. Physiology studies how the different structures of a living organism function as a whole. The origin and descent of species, and their change over time is tackled in evolutionary biology. The grouping and categorization of organisms based on their genus or species allows ease of study and research and is known as scientific classification. It is considered an important aspect of zoology. This book discusses the fundamentals as well as modern approaches of zoology. It unravels the recent studies in this field. It will prove to be immensely beneficial to students and researchers in this field.

Book Description
Economics is traditionally taken to be the social science concerned with the production, consumption, exchange, and distribution of wealth and commodities. Economists carefully track the comings and goings of the human household, whether written small (microeconomics) or large (macroeconomics) and attempt to predict future patterns under different situations. However, in constructing their models of economic behavior, economists often lose sight of the actual characteristics and motivations of their human subjects. In consequence, they have found the goal of an explanatory and predictive science to be elusive. Economics as an Evolutionary Science reorients economics toward a more direct appreciation of human nature, with an emphasis on what we have learned from recent advances in evolutionary science. The authors integrate economics and evolution to produce a social science that is rigorous, internally coherent, testable, and consistent with the natural sciences. The authors suggest an expanded definition of "fitness," as in Darwin's survival of the fittest, emphasizing not only the importance of reproduction and the quality of offspring, but also the unique ability of humans to provide material wealth to their children. The book offers a coherent explanation for the recent decline in fertility, which is shown to be consistent with the evolutionary goal of maximizing genetic success. In addition, the authors demonstrate the relevance to economics of several core concepts derived from biologists, including the genetics of parent-offspring conflict, inclusive fitness theory, and the phenomena of R-selection and K-selection. The keystone of their presentation is a cogent critique of the traditional concept of "utility." As the authors demonstrate, the concept can be modified to reflect the fundamental evolutionary principle whereby living things-including human beings-have been selected to behave in a manner that maximizes their genetic representation in future generations. Despite the extraordinary interest in applying evolutionary biology to other disciplines, Economics as an Evolutionary Science marks the first major attempt at a synthesis of biology and economics. Scholarly yet accessible, this volume offers unique and original perspectives on an entire discipline.

Book Description
Recently Applied and Economic Zoology has been included in national syllabus by UGC for undergraduates. The book examines insect pests, animal pests, natural enemies, beneficial insects, beneficial animals, agricultural chemicals and more. The current book is blueprint for undergraduate students to aware about our natural wild life and its economic importance. The book contains four chapters with illustrations and boxed materials. In the chapter 1, we have covered parasitology, in which we have deliberately discussed about parasites of domestic animals and human, structures, life cycles, pathogenicity, diseases, symptoms and it control. In chapter 2, we consciously talk about vectors and pests. Here, we covered life cycle and control of pest and vectors such as Gundhi bug, Sugarcane leafhopper, Rodents, Termites and Mosquitoes. Chapter 3 is about animal breeding and animal cultures. In this, we stared with basic introduction about breeding and culture, difference between them and then detailed discussion about Animals and Human Society, Animal Breeding, Genetic engineering applications in Animal Breeding, Breeding and Variation, Aquaculture, Pisciculture, Poultry farming, Sericulture, Apiculture, Lac-culture. The last chapter has wild life of India. In this chapter we provided detail for Wild Life Protection and Acts, Documentation of Wild Life, Rare, Endangered and Endemic species, Protected Area Network, Conservation of Wild Life, In-situ and Ex-situ conservation.

Book Description
This textbook addresses the main economic principles required by agricultural economists involved in rural development. The principles of 'micro-economics' or 'price-theory' are of relevance to economists everywhere, but this book reinforces the message of their relevance for rural development by explaining the theory in the specific context of the agricultural and food sectors of developing countries. Hypothetical and actual empirical illustrations drawn almost exclusively from such countries distinguish this book from other economic principles texts that draw their examples almost invariably from industrialised countries, and also from books more oriented to the issue of rural development. The first half of the book deals with the underlying principles of production, supply and demand. These are essential tools for the study and management of the agricultural sector and food markets. In the second half, supply and demand are bought together into a chapter of equilibrium and exchange. This is followed by chapters on trade and the theory of economic welfare. In the final chapter it is shown that much of the material in the earlier chapters can be combined by agricultural economists into a system for analysing and comparing the effects of alternative agricultural policies. The ability of agricultural economics to provide a consistent framework for the analysis of policy problems thus enables it to make a key contribution to rural development.

Book Description
How can geckoes walk on the ceiling and basilisk lizards run over water? What are the aerodynamic effects that enable small insects to fly? What are the relative merits of squids' jet-propelled swimming and fishes' tail-powered swimming? Why do horses change gait as they increase speed? What determines our own vertical leap? Recent technical advances have greatly increased researchers' ability to answer these questions with certainty and in detail. This text provides an up-to-date overview of how animals run, walk, jump, crawl, swim, soar, hover, and fly. Excluding only the tiny creatures that use cilia, it covers all animals that power their movements with muscle--from roundworms to whales, clams to elephants, and gnats to albatrosses. The introduction sets out the general rules governing all modes of animal locomotion and considers the performance criteria--such as speed, endurance, and economy--that have shaped their selection. It introduces energetics and optimality as basic principles. The text then tackles each of the major modes by which animals move on land, in water, and through air. It explains the mechanisms involved and the physical and biological forces shaping those mechanisms, paying particular attention to energy costs. Focusing on general principles but extensively discussing a wide variety of individual cases, this is a superb synthesis of current knowledge about animal locomotion. It will be enormously useful to advanced undergraduates, graduate students, and a range of professional biologists, physicists, and engineers.

Book Description
Can economic growth be environmentally sustainable? This crucial question goes right to the heart of environmental economics and is a matter of increasing concern globally. The first edition of this popular title was the first introductory textbook in environmental economics that truly attempted to integrate economics with not only the environment but also ecology. This new version builds and improves upon the popular formula with new material, new examples, new pedagogical features and new questions for discussion. With international case-studies and examples, this book will prove an excellent choice for introducing both students and other academics to the world of environmental economics.
