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
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.

Book Description
Vertebrate pests cause considerable damage to environment, agriculture and biodiversity apart from transmitting diseases. The problem is more pronounced in tropical Asia and Africa with non-human primates, elephants, several species of ungulates, rodents, frugivorous and grainivorous birds causing agricultural losses. In Europe and America the damage is due to carnivore predation on livestock, bird damage in cereal crops and rodent problem in urban and agricultural situations. Although there are several excellent books on rodent pest management both in India and at global level, there is a conspicuous lacuna of published books on vertebrate pest management. Even the few publications on the subject mostly deal with birds, rodents, bears, rabbits, foxes, etc because they are written by Americans or Britishers. Because their emphasis is on the problem prevalent in their countries and evaluation of management options available to them. In contrast the problem in tropics especially in India is unique. Rodents of course, are the most destructive. But what rodents do over twelve months of year is matched by a few nights of devastating crop raids by elephants or week long foraging by monkeys. Sporadic and localized damage is inflicted by several species of birds, bats, wild boar, blue bull, bears, hares, peacock etc. The damage is sometimes so high, it is impossible for a subsistence farmer to accept stoically the loss of his entire food source over a couple of days and nights. However, his options are limited in view of conservations and protection status enjoyed by some of these animals. The problem is compounded by religious sentiments associated with a few of them. This book is an attempt to find an acceptable solution to the problem of crop losses of these less studied but economically important groups of vertebrate pests. Sincere efforts have gone into formulation of recommendations keeping in mind the biological needs of vertebrate pests, their conservation status and suffering of the poor farmer. Many a time the sympathies deservedly go to the speechless marauders of crops as it is man who has shrunk, degraded and destroyed their habitat, deprived them of their natural source of food. There are no choices for vertebrate pests but raid the crops in their range but we, humans have several to survive. The book is an attempt to understand this dilemma.

Book Description
Science provides an inexorable support to both the human and the nations' development. The great scientists have always provided inspiration by their findings, philosophy, and understanding of the world around us. They have inspired generations of young explorers, eager to learn more about the world and motivated toward betterment with constant efforts in the quest for knowledge. The life of Professor Dr B. Kiauta, Emeritus Professor of Invertebrate Cytogenetics and Cytotaxonomy, University of Utrecht, the Netherlands, President of Societas Internationalis Odonatologica (SIO) and the Executive Editor of Odonatologica, is an open book of assiduous perseverance, focused application and great mentorship. There are indeed many examples of great scientists, or for that matter - odonatologists, in the history of science, but there are certainly absolutely inevitably very few who by their energetic character not only practically educate the budding researchers in habits of industry, but by the example of diligence and perseverance which they set before them, largely influence the scientific activity in all directions and contribute in a great degree to form the national character, or more precisely, the world order! This book, “Dr Bastiaan Kiauta: Odonatologist and Polymath – His Life, Works and Universe”, conveys a great lesson that nothing creditable can be accomplished without application and diligence.

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
In Human Ecodynamics in the North Atlantic: A Collaborative Model of Humans and Nature through Space and Time, Ramona Harrison and Ruth A. Maherhave compiled a series of separate research projects conducted across the North Atlantic region that each contribute greatly to anthropological archaeology. This book assembles a regional model through which the reader is presented with a vivid and detailed image of the climatic events and cultures which have occupied these seas and lands for roughly a 5000-year period. It provides a model of adaptability, resilience, and sustainability that can be applied globally. First, visiting the Northern Isles of Scotland in the Orkney Islands, the reader is taken through the archaeology from the Neolithic Period through World War II in the face of sea-level rise and rapidly eroding coastlines. The Shetland Islands then reveal a deep-time study of one large-scale Iron Age excavation. On to the northern coasts of Norway, where information about late medieval maritime peoples is explained. Iceland explores human–environment interaction and implications of climate change presented from the Viking Age through the Early Modern Era. Rounding out the North Atlantic Region is Greenland, which sheds light on the Norse in the late Viking Age and the Middle Ages.

Book Description
This book discusses current knowledge and challenges with the ecological management and conservation of wetlands, with a focus on the East Kolkata Wetlands of India. This area is referred to as a Ramsar Site, a designation given to areas with special protection statuses, since it is the largest natural waste recycling system in the world. The site faces many threats to its biodiversity and ecosystem functioning due to anthropogenic activity in the region, and therefore an assessment of the ecosystem services, bio-ecological uniqueness, and issues stemming from climate change and human impacts is needed to develop protection strategies for the future ecological functioning and sustainability of the wetlands. The authors use GIS and remote sensing techniques to assess and monitor harmful industrial and environmental impacts on the wetlands, and to inform mitigation and conservation strategies in the face of ongoing threats such as pollution, habitat destruction and bioinvasion. The book also highlights various social and economic aspects tied to the functioning and management of the wetlands, along with ecological, biological, and physio-chemical considerations. The study will be of use to students and researchers in aquatic ecology, biodiversity, and environmental sustainability and conservation, as well as to environmental planners, engineers, and policymakers.
