Originally published in 1972, Homo Sapiens examines how humans emerged from among the millions of other species and achieved our unique position within the animal kingdom. The book examines what direction future evolution will take and what may be regarded as the 'meaning' of human existence. It stipulates that these are the questions for which no real basis of discussion existed before the 20th century, and at the time of publication, some were still without a definite answer. The book sets out analyse these questions and the continuing debate that has arisen from their study. This is an account of the uniqueness of man in the animal kingdom, how this uniqueness arose during evolution, and what traces of it can be detected in animals other than man. The book describes the mental and physical evolution of man, from his earliest ancestors to the present day. He also gives an account of man's cultural development seeking to establish that there is an underlying principal of cultural evolution, a principle that has been denied by many historians. Later chapters deal with the future and with possible forecasts of mankind's further physical, intellectual and cultural evolution.
Since recent years, the population across the globe is increasing expeditiously; hence increasing the agricultural productivity to meet the food demands of the thriving population becomes a challenging task. Abiotic stresses pose as a major threat to agricultural productivity. Having an adequate knowledge and apprehension of the physiology and molecular biology of stress tolerance in plants is a prerequisite for counteracting the adverse effect of such stresses to a wider range. This book deals with the responses and tolerance mechanisms of plants towards various abiotic stresses. The advent of molecular biology and biotechnology has shifted the interest of researchers towards unraveling the genes involved in stress tolerance. More effort is being made to understand and pave ways for developing stress tolerance mechanisms in crop plants. Several technologies including Microarray technology, functional genomics, on gel and off gel proteomic approaches have proved to be of utmost importance by helping the physiologists, molecular biologists and biotechnologists in identifying and exploiting various stress tolerance genes and factors for enhancing stress tolerance in plants. This book would serve as an exemplary source of scientific information pertaining to abiotic stress responses and tolerance mechanisms towards various abiotic stresses.

Nature is all around us, in the beautiful but also in the unappealing and functional, and from the awe-inspiring to the mundane. It is vital that we learn to see the agency of the natural world in all things that make our lives possible, comfortable and profitable. The Ecology of Everyday Things pulls back the veil of our familiarity on a range of 'everyday things' that surround us, and which we perhaps take too much for granted. This key into the magic world of the everyday can enable us to take better account of our common natural inheritance. Professor James Longhurst, Assistant Vice Chancellor, University of the West of England (UWE Bristol) For many people, ecosystems may be a remote concept, yet we eat, drink, breathe and interface with them in every moment of our lives. In this engaging textbook, ecosystems scientist Dr. Mark Everard considers a diversity of 'everyday things', including fascinating facts about their ecological origins: from the tea we drink, to the things we wear, read and enjoy, to the ecology of communities and space flight, and the important roles played by germs and 'unappealing creatures' such as slugs and wasps. In today's society, we are so umbilically connected to ecosystems that we fail to notice them, and this oversight blinds us to the unsustainability of everyday life and the industries and policy environment that supports it. The Ecology of Everyday Things takes the reader on an enlightening, fascinating voyage of discovery, all the while soundly rooted in robust science. It will stimulate awareness about how connected we all are to the natural world and its processes, and how important it is to learn to better treat our environment. Ideal for use in undergraduate- and school-level teaching, it will also interest, educate, engage and enthuse a wide range of less technical audiences.

Rethinking Wilderness and the Wild: Conflict, Conservation and Co-existence examines the complexities surrounding the concept of wilderness. Contemporary wilderness scholarship has tended to fall into two categories: the so-called 'fortress conservation' and 'co-existence' schools of thought. This book, contending that this polarisation has led to a silencing and concealment of alternative perspectives and lines of enquiry, extends beyond these confines and in particular steers away from the dilemmas of paradise or paradox in order to advance an intellectual and policy agenda of plurality and diversity rather than of prescription and definition. Drawing on case studies from Australia, Aoteoroa/New Zealand, the United States and Iceland, and explorations of embodied experience, creative practice, philosophy, and First Nations land management approaches, the assembled chapters examine wilderness ideals, conflicts and human-nature dualities afresh, and examine co-existence and conservation in the Anthropocene in diverse ontological and multidisciplinary ways. By demonstrating a strong commitment to respecting the knowledge and perspectives of Indigenous peoples, this work delivers a more nuanced, ethical and decolonising approach to issues arising from relationships with wilderness. Such a collection is immediately appropriate given the political challenges and social complexities of our time, and the mounting threats to life across the globe. The abiding and uniting logic of the book is to offer a unique and innovative contribution to engender transformations of wilderness scholarship, activism and conservation policy. This text refutes the inherent privileging and exclusionary tactics of dominant modes of enquiry that too often serve to silence non-human and contrary positions. It reveals a multi-faceted and contingent wilderness alive with agency, diversity and possibility. This book will be of great interest to students and scholars of conservation, environmental and natural resource management, Indigenous studies and environmental policy and planning. It will also be of interest to practitioners, policymakers and NGOs involved in conservation, protected environments and environmental governance.
