This book describes one of our closest relatives, the orangutan, and the only extant great ape in Asia. It is increasingly clear that orangutan populations show extensive variation in behavioral ecology, morphology, life history, and genes. Indeed, on the strength of the latest genetic and morphological evidence, it has been proposed that orangutans actually constitute two species which diverged more than a million years ago - one on the island of Sumatra the other on Borneo, with the latter comprising three subspecies.
This book has two main aims. The first is to carefully compare data from every orangutan research site, examining the differences and similarities between orangutan species, subspecies and populations. The second is to develop a theoretical framework in which these differences and similarities can be explained. To achieve these goals the editors have assembled the world's leading orangutan experts to rigorously synthesize and compare the data, quantify the similarities or differences, and seek to explain them.
Orangutans is the first synthesis of orangutan biology to adopt this novel, comparative approach. It analyses and compares the latest data, developing a theoretical framework to explain morphological, life history, and behavioral variation. Intriguingly, not all behavioral differences can be attributed to ecological variation between and within the two islands; relative rates of social learning also appear to have been influential. The book also emphasizes the crucial impact of human settlement on orangutans and looks ahead to the future prospects for the survival of critically endangered natural populations.

"[A] glorious guide to the miracle of life's sound." -The New York Times Book Review A lyrical exploration of the diverse sounds of our planet, the creative processes that produced these marvels, and the perils that sonic diversity now faces We live on a planet alive with song, music, and speech. David Haskell explores how these wonders came to be. In rain forests shimmering with insect sound and swamps pulsing with frog calls we learn about evolution's creative powers. From birds in the Rocky Mountains and on the streets of Paris, we discover how animals learn their songs and adapt to new environments. Below the waves, we hear our kinship to beings as different as snapping shrimp, toadfish, and whales. In the startlingly divergent sonic vibes of the animals of different continents, we experience the legacies of plate tectonics, the deep history of animal groups and their movements around the world, and the quirks of aesthetic evolution. Starting with the origins of animal song and traversing the whole arc of Earth history, Haskell illuminates and celebrates the emergence of the varied sounds of our world. In mammoth ivory flutes from Paleolithic caves, violins in modern concert halls, and electronic music in earbuds, we learn that human music and language belong within this story of ecology and evolution. Yet we are also destroyers, now silencing or smothering many of the sounds of the living Earth. Haskell takes us to threatened forests, noise-filled oceans, and loud city streets, and shows that sonic crises are not mere losses of sensory ornament. Sound is a generative force, and so the erasure of sonic diversity makes the world less creative, just, and beautiful. The appreciation of the beauty and brokenness of sound is therefore an important guide in today's convulsions and crises of change and inequity. Sounds Wild and Broken is an invitation to listen, wonder, belong, and act.

When a blonde who had walked out on her Botswana-based wildlife smuggling kingpin partner arrived at the offices of the Sunday Times in the last 1980’s, the lid would be blown off a criminal network bent on killing off two of the world’s most iconic species – the elephant and the rhino.

Using trucks to transport contraband across borders to curio shops fronting as legitimate operate operations, the syndicate operated with free abandon, until their nefarious activities were revealed through investigations by journalist De Wet Potgieter. It was because of the information supplied by Brenda Voue that De Wet was inundated with so much information about the involvement of local and foreign criminal networks, senior military officials propping up the Jonas Savimbi’s war in Angola, and senior National Party officials that he authored not only several more newspaper articles on the plight of rhino and elephant, but also produced the first edition of Contraband in 1995. Since then, a plethora of information continues to come to light about the involvement of government officials, international spies, British undercover operatives, businesspeople, and criminal elements.

This is an exposure of the depths to which certain people would go to literally enjoy a piece of the pie. The commercial international rhino horn trade has been banned by the Convention on the International Trade in Endangered Species of Wild Fauna and Flora (CITES) for more than 45 years. In South Africa, the domestic trade in rhino horn has been legal since 2017 opening loopholes from criminal syndicates to “legally” purchase rhino horn, but then still smuggle it out of the country for traditional uses in the Far East. The involvement of criminal operations such as the Triads cannot be ignored, nor can the pressure pre- and post-apartheid on the South African police’s highly successful Endangered Species Protection Unit under Colonel Piet Lategan, which resulted it its eventual demise. It’s an inescapable fact that the onslaught on South Africa’s rhino, and on other wildlife within the Southern African region, will continue despite the commitment and tenacity of several individuals and nongovernment organisations.

The onus has now shifted to the custodians of rhino – national parks, game reserves, private game ranchers and private rhino owners – to protect these prehistoric beasts from extinction.

'The most magical book about the African bush since Born Free' - Daily Mail

'A beautiful love story between humans and the majestic elephants' Jo Malone, Daily Express

Françoise Malby-Anthony never expected to find herself responsible for a herd of elephants with a troubled past. A chic Parisienne, her life changed forever when she fell in love with South African conservationist Lawrence Anthony. Together they founded a game reserve but after Lawrence’s death, Françoise faced the daunting responsibility of running Thula Thula without him. Poachers attacked their rhinos, their security team wouldn’t take orders from a woman and the authorities were threatening to cull their beloved elephant family. On top of that, the herd’s feisty new matriarch Frankie didn’t like her.

In this heart-warming and moving book, Françoise describes how she fought to protect the herd and to make her dream of building a wildlife rescue centre a reality. She found herself caring for a lost baby elephant who turned up at her house, and offering refuge to traumatized orphaned rhinos, and a hippo called Charlie who was scared of water. As she learned to trust herself, she discovered she’d had Frankie wrong all along . . .

Filled with extraordinary animals and the humans who dedicate their lives to saving them, An Elephant in My Kitchen by Françoise Malby-Anthony is a captivating and gripping read.

The J.N. "Ding" Darling National Wildlife Refuge was created as the Sanibel National Wildlife Refuge on December 1, 1945, during the administration of Pres. Harry S. Truman. The refuge was renamed in 1967 to honor J.N. "Ding" Darling, a syndicated editorial cartoonist. He wintered on Captiva Island and advocated the establishment of the refuge. Situated on a barrier island in Southwest Florida, the refuge is a jewel among the 553 units of the National Wildlife Refuge System. Sanibel, once cherished by the conquistadors, is renowned as one of the best places on the planet to collect seashells and watch birds. Now an island-city, incorporated in 1974, Sanibel is famous for its land development code, which helps make the city a special place. "Ding" Darling would not completely approve of what has happened to the island he once loved, but he would applaud the human effort that has saved the island's wetlands and nurtured his wildlife refuge.

A book of evocative and atmospheric photographs taken by Dick Hawkes to create a representative record of this precious and ecologically unique habitat - before much of it is lost to the many threats it faces. Chalk streams have been described as England's "rainforest". Around 85% of the world's chalk streams are in England. They are beautiful, biologically distinct and amazingly rich in wildlife, but are under threat from man-made issues of abstraction, pollution from chemicals and effluent, development for housing, and climate change. Included in the book are images of typical habitats and species of wildlife found in chalk streams and water meadows, highlighting those that are rare or most under threat.

How does a mudskipper fish manage to “walk� on land? Why is the Hoatzin also known as ‘The Stinkbird’? And once the female Pipa toad has laid her eggs, where does she put them? The answers? The mudskipper can “walk� using its pectoral fins, the Hoatzin has a unique digestive system which gives the bird a manure-like odour, and the female Pipa Toad embeds its eggs on its back where they develop to adult stage. Illustrated throughout with outstanding colour photographs, Strange Animals presents the most unusual aspects of 100 of the most unusual species. The selection spans a broad spectrum of wildlife, from the tallest land living mammal, the giraffe, to the light, laughing chorus of Australian kookaburra birds, from the intelligence of the Bottlenose dolphin to octopuses that change colour when they dream to the slow pace of the three-toed sloth. Arranged geographically, the photographs are accompanied by fascinating captions, which explain the quirky characteristics of each entry. Including egg-laying mammals, birds, reptiles, amphibians, cannibalistic insects and other invertebrates, Strange Animals is a compelling introduction to some of nature’s most curious beasts.

Elgar Advanced Introductions are stimulating and thoughtful introductions to major fields in the social sciences, business and law, expertly written by the world's leading scholars. Designed to be accessible yet rigorous, they offer concise and lucid surveys of the substantive and policy issues associated with discrete subject areas. Professor Fikret Berkes provides a unique introduction to the social and interdisciplinary dimensions of biodiversity conservation. Examining a range of approaches, new ideas, controversies and debates, he demonstrates that biodiversity loss is not primarily a technical issue, but a social problem that operates in an economic, political and cultural context. Berkes concludes that conservation must be democratized in order to broaden its support base and build more inclusive constituencies for conservation. Key features include: focus on Indigenous peoples' rights, knowledge and practices discussion of commons governance, co-management and responsibility exploration of the history of conservation and the nature stewardship traditions a broad view of conservation that encompasses the well-being of humans as well as ecosystems Taking an interdisciplinary social science approach that includes conservation science concepts, this Advanced Introduction will benefit students of environmental studies, geography, ecology and conservation. It will also be a useful resource for conservation organizations.

Peter Jewell and Juliet Clutton-Brock had a shared passion for animals and Africa, and as brilliant young zoologists in the 1960s they were pioneers of the new movements in ecology, archaeozoology and animal conservation. This fascinating account of their extraordinary lives follows them as they travel, and live, in and out of Africa accompanied by their three daughters and a medley of pets, including dogs, cats, tortoises, chameleons and a chimpanzee.

A David and Goliath conservation story set on Lake Michigan.

’I can’t recall us ever talking about anything other than eels and how to best catch them, down there by the stream. Actually, I can’t remember us speaking at all. Maybe because we never did.’

The European eel, Anguilla anguilla, is one of the strangest creatures nature ever created. Remarkably little is known about the eel, even today. What we do know is that it’s born as a tiny willow-leaf shaped larva in the Sargasso Sea, travels on the ocean currents toward the coasts of Europe – a journey of about four thousand miles that takes at least two years. Upon arrival, it transforms itself into a glass eel and then into a yellow eel before it wanders up into fresh water. It lives a solitary life, hiding from both light and science, for ten, twenty, fifty years, before migrating back to the sea in the autumn, morphing into a silver eel and swimming all the way back to the Sargasso Sea, where it breeds and dies.

And yet . . . There is still so much we don’t know about eels. No human has ever seen eels reproduce; no one can give a complete account of the eel’s metamorphoses or say why they are born and die in the Sargasso Sea; no human has even seen a mature eel in the Sargasso Sea. Ever. And now the eel is disappearing, and we don’t know exactly why.

What we do know is that eels and their mysterious lives captivate us.

This is the basis for The Gospel of the Eels, Patrik Svensson’s quite unique natural science memoir; his ongoing fascination with this secretive fish, but also the equally perplexing and often murky relationship he shared with his father, whose only passion in life was fishing for this obscure creature.

Through the exploration of eels in literature (Günter Grass and Graham Swift feature, amongst others) and the history of science (we learn about Aristotle’s and Sigmund Freud’s complicated relationships with eels) as well as modern marine biology (Rachel Carson and others) we get to know this peculiar animal. In this exploration, we also learn about the human condition, life and death, through natural science and nature writing at its very best.

In explaining how developments in the Kruger National Park have been integral to the wider political and socio-economic concerns of South Africa, this text opens an alternative perspective on its history. Nature protection has evolved in response to a variety of stimuli including white self-interest, Afrikaner nationalism, ineffectual legislation, elitism, capitalism and the exploitation of Africans.

World Oceans: A Reference Handbook offers an in-depth discussion of the world's oceans. It discusses the marine life that is dependent on the sea as well as the problems threatening the health of the ocean and its wildlife. World Oceans: A Reference Handbook opens with an overview of the history of human knowledge and understanding of the oceans and cryosphere, along with related scientific, technological, social, political, and other factors. The second chapter presents and discusses about a dozen major problems facing the Earth's oceans today, along with possible solutions. The third chapter provides interested individuals with an opportunity to express their thoughts and ideas on today's ocean issues, and remaining chapters provide additional resources, such as a bibliography, a chronology, and a glossary, to assist the reader in her or his further study of the issue. Where most books for young adults learning about world oceans take a purely expository treatment, this book provides readers with additional information as well as resources, allowing them to learn more and inform further study of the subject. Provides readers with the basic background they need about the oceans and cryosphere in order to understand current problems Includes additional readings, a comprehensive chronology, a glossary, and other additional features to aid students' understanding of current issues and to guide them in designing and conducting their own research on more detailed aspects of the topic Offers ideas for additional research from a list of important individuals and organizations Rounds out the author's expertise in perspectives essays that show readers a diversity of viewpoints

Fifty years after the Stockholm Conference first placed the environment on the international development agenda, this Handbook continues the debate. The Handbook discusses both the profound environmental and theoretical critique against development as modernization and economic growth, and how perspectives on nature have changed from an infinite resource to a fragile subject. Weighing up the successes and failures linked to environmental concerns in development and environment policy and practice, it recognizes the roots of international development as a Western project linked to the expansion of an environmentally destructive capitalism. Through active dialogue across geographical areas, disciplines and epistemologies, chapters critically assess current perspectives on the topic, including decolonialism, degrowth and post-development. Grounded in recent research on topics such as agriculture, fisheries, infrastructure, forest protection, supply chain management, climate negotiations and the renewable transition, the Handbook integrates a range of different viewpoints on international development and the environment to provide a fresh take on this contentious relationship. With an international scope, this expansive Handbook will be integral reading for students and scholars of development and the environment. It will also be a beneficial read for practitioners working in international organizations and development agencies.

Norfolk played a unique role in the development of conservation. This book narrates the story of the movement, from its origins five hundred years ago to the present day. Rare and beautiful Norfolk, as described by the artist John Sell Cotman in 1841, with its rich wildlife habitats, historic buildings, diverse landscapes and archaeological sites, has long been a focus of interest for both naturalists and antiquarians. It has also been at the forefront of the modern conservation movement. The Norfolk Archaeological Trust, still the only local trust of its kind, was founded in 1923; the Norfolk Naturalist Trust, (later the Norfolk Wildlife Trust), founded in 1926, was the first county wildlife trust; while Blickling Hall was the first property to be accepted by the National Trust under its Country House Scheme. By the 1970s traditional marsheswere seen as particularly under threat and it was proposals to drain part of the Broadland marshes that led to the introduction of conservation schemes which have transformed much of British agriculture. In this engaging book, the author traces the history of the conservation movement and the people who were involved, including the Norfolk botanist and founder of the Linnean Society, Sir James Smith. In particular, she shows the influence of changingsocial attitudes and priorities upon the movement and ideas of heritage. Susanna Wade Martins is an honorary fellow of the School of History at the University of East Anglia; her previous publications include Coke ofNorfolk: A Biography and The Countryside of East Anglia (with Tom Williamson).

The interconnectedness of global society is increasingly visible through crises such as the current global health pandemic, emerging climate change impacts and increasing erosion of biodiversity. This timely Handbook navigates the challenges of adaptive governance in these complex contexts, stressing the necessarily compounded nature of bio-physical and social systems to ensure more desirable governance outcomes. Highlighting the dynamics and diversity of governance systems across the globe, leading experts in the field examine the successes and failures of these systems. Synthesising theory with methodology and practical case studies, chapters explore adaptive governance in forest management, marine environments and open data ecosystems, looking closely at the role of adaptive governance in climate mitigation and disaster risk reduction. Answering the call for large-scale transformations that move societies away from unsustainable development trajectories, this prescriptive Handbook explores the existing adaptive governance measures that have driven reflexive, sustainable change. Reflecting on the past decade of research in the field, it concludes by outlining new areas of contention and inquiry for the next decade of adaptive governance research. Interdisciplinary in scope, this comprehensive Handbook will prove an invigorating read for students and scholars of environmental law, governance and regulation, and political science and public policy. Policymakers looking to innovate their adaptive governance approaches will also find this a beneficial companion.

Illustrated throughout with 200 outstanding colour photographs, Endangered Animals presents an in-depth look at around 100 species of animal from around the world, all of which are currently endangered or threatened according to the annual list drawn up by the World Conservation Union (IUCN). The selection spans a broad spectrum of wildlife, from large, charismatic mammals such as the Bengal tiger to lesser-known species such as New Zealand's kakapo, the world's only flightless parrot, which was once presumed to be extinct. Each continent is covered, with examples carefully drawn from every habitat - from the mysterious aye-aye of Madagascar's shrinking rainforest, to the shy spectacled bear of the high Andes. Arranged geographically, each photographic entry is supported by a fascinating caption, which explains the animal's current plight and whether it is critically endangered or classified as vulnerable. From the Ethiopian wolf to the Bengal tiger to monk seal and dugong, Endangered Animals is a fascinating introduction to some of the most threatened species on the planet.

Over the last eight years I have spent much time looking into some really important questions: why do we have a climate and how has it changed? what role has the human race played in these changes? what will be the consequences if we continue burning fossils fuels? can we produce enough renewable, carbon neutral energy for the future, allowing for an increase in world population and for economic growth? The challenge - if we are to limit the long term global temperature rise to just 1 C above the current level, then we need to take urgent action. By 2050 the world must be producing seven times the amount of renewables we use today . This means that over the next 35 years we will have to develop these sources of energy 12 times faster than we've done in the last 35 years. We have to act now - this is our wake-up call. Getting governments to adopt policies with long term benefits is always difficult when they involve major short term investment but getting international agreement on limiting global warming is crucial. National targets must be agreed as well as an effective means of monitoring and enforcing them. Agreement must be based on the long term interests of the world not just on what is best "now, for me". Seven countries, China, USA, India, Russia, Japan, Canada and South Korea plus the EU account for three quarters of current greenhouse gas emissions. Negotiations must begin by getting these parties to agree on targets for themselves. They must then meet these targets and get everyone else to follow suit.
