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

Wetzel s Limnology Lake and River Ecosystems Fourth Edition presents a fully updated revision of the classic textbook Limnology Lake and River Ecosystems last published in 2001 The coverage has been thoroughly updated with recent research and theoretical developments Each chapter of this edited volume has been written by an expert or team of experts providing a comprehensive and global perspective with the editors working closely with the authors to maintain continuity within and between the chapters This is not only an essential textbook for undergraduate and graduate students in limnology but also a standard reference book for seasoned limnologists and other scientists

The second edition of this widely cited textbook continues to provide a concise but comprehensive introduction to cave and subterranean biology describing this fascinating habitat and its biodiversity It covers a range of biological processes including ecosystem function evolution and adaptation community ecology biogeography and conservation The authors draw on a global range of examples and case studies from both caves and non cave subterranean habitats One of the barriers to the study of subterranean biology has been the extraordinarily large number of specialized terms used by researchers the authors explain these terms clearly and minimize the number that they use This new edition retains the same 10 chapter structure of the original but the content has been thoroughly revised and updated throughout to reflect the huge increase in publications concerning subterranean biology over the last decade

How we view nature transforms the world around us People rehearse stories about nature which make sense to them If we ask the question why conserve nature and the answers are based on myths then are these good myths to have Scientific knowledge about the environment is fundamental to ideas about how nature works It is essential to the conservation endeavour However any conservation motivation is nested within a society s meanings of nature and the way society values it Given the therapeutic and psychological significance of nature for us and our culture this book considers the meanings derived from the poetic and emotional attachment to a sense of place which is arguably just as important as scientific evidence The functional significance of species is important but so too is the therapeutic value of nature together with the historic and spiritual meanings entwined in a human feeling for landscape and wildlife

For decades the world s governments have struggled to move from talk to action on climate Many now hope that growing public concern will lead to greater policy ambition but the most widely promoted strategy to address the climate crisis the use of market based programs hasn t been working and isn t ready to scale Danny Cullenward and David Victor show how the politics of creating and maintaining market based policies render them ineffective nearly everywhere they have been applied Reforms can help around the margins but markets problems are structural and won t disappear with increasing demand for climate solutions Facing that reality requires relying more heavily on smart regulation and industrial policy government led strategies to catalyze the transformation that markets promise but rarely deliver

This book presents information on common to rare organisms from around the world that inhabit freshwater habitats

From ancient acorns to future forests the story of how oaks evolved and the many ways they shape our world An oak begins its life with the precarious journey of a pollen grain then an acorn then a seedling A mature tree may shed millions of acorns but only a handful will grow One oak may then live 100 years 250 years or even 13 000 years But the long life of an individual is only a part of these trees story With naturalist and leading researcher Andrew L Hipp as our guide Oak Origins takes us through a sweeping evolutionary history stretching back to a population of trees that lived more than 50 million years ago We travel to the ancient tropical Earth to see the ancestors of the oaks evolving side by side with the dinosaurs We journey from the oaks childhood in the once warm forests of the Arctic to the montane cloud forests of Mexico and the broad leaved evergreen forests of Southeast Asia We dive into current research on oak genomes to see how scientists study genes movement between species and how oaks evolve over generations spanning tens of millions of years Finally we learn how oak evolutionary history shapes the forests we know today and how it may even shape the forests of the future Oaks are familiar to almost everyone and beloved Th

United Nations Champion of the Earth climate scientist and evangelical Christian Katharine Hayhoe changes the debate on how we can save our future in this nationally bestselling optimistic view on why collective action is still possible and how it can be realized The New York Times Called one of the nation s most effective communicators on climate change by The New York Times Katharine Hayhoe knows how to navigate all sides of the conversation on our changing planet A Canadian climate scientist living in Texas she negotiates distrust of data indifference to imminent threats and resistance to proposed solutions with ease Over the past fifteen years Hayhoe has found that the most important thing we can do to address climate change is talk about it and she wants to teach you how In Saving Us Hayhoe argues that when it comes to changing hearts and minds facts are only one part of the equation We need to find shared values in order to connect our unique identities to collective action This is not another doomsday narrative about a planet on fire It is a multilayered look at science faith and human psychology from an icon in her field recently named chief scientist at The Nature Conservancy Drawing on interdisciplinary research and personal stories

Small Carnivores Evolution Ecology Behaviour and Conservation This book focuses on the 232 species of the mammalian Order Carnivora with an average body mass 21 5 kg Small carnivores inhabit virtually all of the Earth s ecosystems adopting terrestrial semi fossorial semi arboreal or semi aquatic lifestyles They occupy multiple trophic levels and therefore play important roles in the regulation of ecosystems such as natural pest control seed dispersal and nutrient cycling In areas where humans have extirpated large carnivores small carnivores may become the dominant predators which may increase their abundance mesopredator release to the point that they can sometimes destabilize communities drive local extirpations and reduce overall biodiversity On the other hand one third of the world s small carnivores are threatened or near threatened with extinction This results from regionally burgeoning human populations industrial and agricultural activities causing habitat reduction destruction fragmentation and pollution Overexploitation persecution and the impacts of introduced predators competitors and pathogens have also negatively affected many small carnivore species Although small carnivores have been intensively studied over the p

How the science of ecology is changing to meet the daunting challenges of environmental sustainabilityOur species has transitioned from being one among millions on Earth to the species that is single handedly transforming the entire planet to suit its own needs The New Ecology shows how today s ecology can provide the insights we need to appre

A completely up to date introduction to the most common group of bees in Britain Bees for most people mean honey or bumble bees but in fact these social species make up only a small proportion of the species that live in Britain Open your eyes to the so called solitary bees and discover a wonderfully diverse population miners leafcutters carpenters and masons many of which can be found in your own back garden Solitary bees come in a variety of colours and sizes with some as large as bumblebees and some only a few millimetres long and many are key pollinators for our crops and wildflowers This comprehensive book will tell the story of how these bees live reproduce and thrive discover the numerous strategies used by male bees to find females and persuade them to mate follow the females as they build their nests or in the case of cuckoo species sneak into the nests of their neighbours and watch as the new generation appears Explore the interactions between flowering plants and their bee visitors asking what the plants get from the relationship as well as how the bees select the plants they visit and the ingenuity required to extract pollen nectar and other rewards Finally learn places where bees flourish and what can be done to encourage t

Microbial ecology is the study of interactions among microbes in natural environments and their roles in biogeochemical cycles food web dynamics and the evolution of life Microbes are the most numerous organisms in the biosphere and mediate many critical reactions in elemental cycles and biogeochemical reactions Because they are essential players in the carbon cycle and related processes microbial ecology is a vital science for understanding the role of the biosphere in global warming and the response of natural ecosystems to climate change This second edition has been fully revised restructured and updated while remaining concise and accessible It discusses the major processes carried out by viruses bacteria fungi protozoa and other protists the microbes in freshwater marine and terrestrial ecosystems The focus is on biogeochemical processes starting with primary production and the initial fixation of carbon into cellular biomass before exploring how that carbon is degraded in both oxygen rich oxic and oxygen deficient anoxic environments These processes are in turn affected by ecological interactions including competition for limiting nutrients viral lysis and predation by various protists in soils and aquatic habitats The book neatly co

This work sounds an early warning about an environmental catastrophe that has become all too familiar today the invasion of nonnative species The author explains the devastating effects that invasive species can have on local ecosystems

Global temperatures and seawater levels rise the world s smallest porpoise species looms at the edge of extinction and a tiny emerald beetle from Japan flourishes in North America but why does it matter Who cares With this concise accessible and up to date book Charles J Krebs answers critics and enlightens students and environmental advocates alike revealing not why phenomena like these deserve our attention but why they demand it Highlighting key principles in ecology from species extinction to the sun s role in powering ecosystems each chapter introduces a general question illustrates that question with real world examples and links it to pressing ecological issues in which humans play a central role such as the spread of invasive species climate change overfishing and biodiversity conservation While other introductions to ecology are rooted in complex theory math or practice and relegate discussions of human environmental impacts and their societal implications to sidebars and appendices Why Ecology Matters interweaves these important discussions throughout It is a book rooted in our contemporary world delving into ecological issues that are perennial timeless but could not be more timely

A fresh look at the world s water crises and the existing and emerging solutions that can be used to solve them

Laura J Martin examines ecological restoration s long history Since the early 1900s restorationists have confronted vexing philosophical questions Which states of nature should be restored Who should choose Is human designed wilderness really wild Restoration work leads us to reimagine nature and the nature of environmental justice

Now that Trump has turned the United States into a global climate outcast will China take the lead in saving our planet from environmental catastrophe Many signs point to yes China the world s largest carbon emitter is leading a global clean energy revolution phasing out coal consumption and leading the development of a global system of green finance But as leading China environmental expert Barbara Finamore explains it is anything but easy The fundamental economic and political challenges that China faces in addressing its domestic environmental crisis threaten to derail its low carbon energy transition Yet there is reason for hope China s leaders understand that transforming the world s second largest economy from one dependent on highly polluting heavy industry to one focused on clean energy services and innovation is essential not only to the future of the planet but to China s own prosperity
