Presenting a global and interdisciplinary approach to plant ecology this much awaited new edition of the book Plants and Vegetation integrates classical themes with the latest ideas models and data Keddy draws on extensive teaching experience to bring the field to life guiding students through essential concepts with numerous real world examples and full colour illustrations throughout The chapters begin by presenting the wider picture of the origin of plants and their impact on the Earth before exploring the search for global patterns in plants and vegetation Chapters on resources stress competition herbivory and mutualism explore causation and a concluding chapter on conservation addresses the concern that one third of all plant species are at risk of extinction The scope of this edition is broadened further by a new chapter on population ecology along with extensive examples including South African deserts the Guyana Highlands of South America Himalayan forests and arctic alpine environments

That humans originated from Africa is well known However this is widely regarded as a chance outcome dependant simply on where our common ancestor shared the land with where the great apes lived This volume builds on from the Out of Africa theory and takes the view that it is only in Africa that the evolutionary transitions from a forest inhabiting frugivore to savanna dwelling meat eater could have occurred This book argues that the ecological circumstances that shaped these transitions are exclusive to Africa It describes distinctive features of the ecology of Africa with emphasis on savanna grasslands and relates them to the evolutionary transitions linking early ape men to modern humans It shows how physical features of the continent especially those derived from plate tectonics set the foundations This volume adequately conveys that we are here because of the distinctive features of the ecology of Africa

What can we really do about the climate emergency The inconvenient truth is that we are causing the climate crisis with our carbon intensive lifestyles and that fixing or even just slowing it will affect all of us But it can be done In Net Zero economist Dieter Helm addresses the action we all need to take to tackle the climate emergency personal local national and global Reducing our own carbon consumption is the first step Helm argues that we the ultimate polluters should pay based on how much carbon the products we buy produce We need a carbon price and one that applies to everything and everywhere from flights to food and farming The goal of net zero carbon emissions needs a rethink and this book sets out how to do it in a plan that could and would work Do this and we make no further contribution to global warming in a way that embraces sustainable economic growth and does not harm other aspects of the environment in the process There is a solution and we must find it Everything is at stake

Tropical East Asia is home to over one billion people and faces massive human impacts from its rising population and rapid economic growth It has already lost more than half of its forest cover to agriculture and urbanization and has the highest rates of deforestation and logging in the tropics Habitat loss coupled with hunting and the relentless trade in wildlife products threatens all its large and many of its smaller vertebrates Despite these problems the region still supports an estimated 15 25 of global terrestrial biodiversity and a growing environmental awareness means that it is no longer assumed that economic development justifies environmental damage and no longer accepted that this trade off is inevitable Effective conservation action now depends on integrating a clear understanding of the ecological patterns and processes in the region with the varied needs of its human population This third edition continues to provide an overview of the terrestrial ecology of Tropical East Asia from southern China to Indonesia and from Bhutan and Bangladesh to the Ryukyu Islands of Japan It retains the balance between compactness and comprehensiveness of the previous editions and the even handed geographical treatment of the whole region but it updates both

This is a open access book Ranaviruses double stranded DNA viruses family Iridoviridae that cause systemic life threatening disease in a variety of amphibians reptiles and fish have contributed to mass die offs of both wild and captive populations around the globe These viruses are emerging and increasingly responsible for population declines of ectothermic vertebrates Because amphibians reptiles and freshwater turtles are suitable hosts and among the most imperiled vertebrate taxa in the world ranaviruses can have significant impacts on biodiversity and ecosystem function Additionally many fish that are raised in aquaculture facilities and traded internationally are suitable hosts thus the potential economic impact of ranaviruses is significant Ranaviruses also serve as a model for understanding viral replication and gene function among large double stranded DNA viruses e g poxviruses asfarvirus and ascoviruses Lastly study of the host immune response to ranaviral disease and the identification of viral immune evasion genes that negatively regulate host immune functions provide insight into which specific immune elements are most important in protecting host species against severe disease The effort to produce a 2nd edition of our earlier work

Water is central to all life but we use it to destroy Water can nourish but we use it to starve It can cleanse and unify but we ensure it contaminates and divides The consequences of continuing to desecrate or beginning to restore water s inner grace are tremendous and will reflect as much on us as portend our future Drawing upon twenty five years of professional work as a water engineer negotiator and scholar Mark Zeitoun provides a unique insider s account of this phenomenon He explains how unchecked assumptions about water mix with political and economic systems to create an insatiable and ruinous thirst for ever more water He shows how we use water to lethal effect in wars and demolish drinking water systems with wanton disregard He questions why we transform the most majestic of rivers into canals which spark international conflict and challenge our capacity for preventative diplomacy The answers reflect more about our society than we might care to admit If we are to restore water s inner grace Zeitoun argues we should worry not so much about saving water but think about what we do with it when it is in our hands

Terrestrial Biosphere tries to pose the questions which underlie the many sided debate of how to respond to and influence change How should we view nature What do we do for the best how should we act what are we trying to achieve and what should we be guided by In doing so the book introduces and attempts to analyse not only scientific aspects of the debate but also cultural attitudes and values the notions of ecosystem stability are now challenged and it is also clear that ecosystems are renewable but not repeatable It finds that prescriptive solutions based on current constructs may not be adequate Feeling that analysis should lead to advocacy the author believes that if we can t improve predictability we have to increase adaptability which means that ecological and social capacity building should be advocated This is seen in terms of concepts institutions attitudes and values which allow for a plurality of meanings and which can cope with surprise and unforeseen change and which also facilitates responses to change
