Corridors to Extinction and the Australian Megafauna by Steve Webb Pdf

Extinctions have always occurred and always will, so what is so surprising about the megafauna extinctions? They were caused by humans and were the first of many extinctions that eventually led to the extinction of the Moa, Steller's Sea Cow, the Dodo, Great Auk and countless other species great and small, all attributed to human agency. Therefore, the megafauna were humans’ first great impact on the planet. There is now an increasing realization that the 'blitzkrieg' view of these extinctions may have been wrong. A growing body of evidence and long-term field work is beginning to show that at least Australia's megafauna did not succumb to human agency, not because humans probably did not hunt the odd animal but because the an infinitely more logical reason lies in the climatic conditions of the Quaternary Ice Ages and the affect they had on continental geography, environment, climate and, most importantly, the biogeography of the megafauna. This book presents the evidence of this theory, demonstrating the biogeographic approach to Australia’s megafauna extinction. Written clearly to benefit a diverse level of readers, from those with a passing interest to professionals in the field. Examines future climate change and its effects on the planet by looking at examples buried in the past Presents new evidence from extensive field research

The Archaeology of Rock Art in Western Arnhem Land, Australia by Bruno David,Paul Taçon,Jean-Jacques Delannoy,Jean-Michel Geneste Pdf

Western Arnhem Land, in the Top End of Australia’s Northern Territory, has a rich archaeological landscape, ethnographic record and body of rock art that displays an astonishing array of imagery on shelter walls and ceilings. While the archaeology goes back to the earliest period of Aboriginal occupation of the continent, the rock art represents some of the richest, most diverse and visually most impressive regional assemblages anywhere in the world. To better understand this multi-dimensional cultural record, The Archaeology of Rock Art in Western Arnhem Land, Australia focuses on the nature and antiquity of the region’s rock art as revealed by archaeological surveys and excavations, and the application of novel analytical methods. This volume also presents new findings by which to rethink how Aboriginal peoples have socially engaged in and with places across western Arnhem Land, from the north to the south, from the plains to the spectacular rocky landscapes of the plateau. The dynamic nature of Arnhem Land rock art is explored and articulated in innovative ways that shed new light on the region’s deep time Aboriginal history.

Australian Deserts by Steve Morton Pdf

Australian Deserts: Ecology and Landscapes is about the vast sweep of the Outback, a land of expanses making up three-quarters of the continent – the heart of Australia. Steve Morton brings his extensive first-hand knowledge and experience of arid Australia to this book, explaining how Australian deserts work ecologically. This book outlines why unpredictable rainfall and paucity of soil nutrients underpin the nature of desert ecosystems, while also describing how plants and animals came to be desert dwellers through evolutionary time. It shows how plants use uncertain rainfall to provide for persistence of their populations, alongside outlines of the dominant animals of the deserts and explanations of the features that help them succeed in the face of aridity and uncertainty. Richly illustrated with the photographs of Mike Gillam, this fascinating and accessible book will enhance your understanding of the nature of arid Australia.

Vanished Giants by Anthony J. Stuart Pdf

Featuring numerous illustrations, this book explores the many lessons to be learned from Pleistocene megafauna, including the role of humans in their extinction, their disappearance at the start of the Sixth Extinction, and what they might teach us about contemporary conservation crises. Long after the extinction of dinosaurs, when humans were still in the Stone Age, woolly rhinos, mammoths, mastodons, sabertooth cats, giant ground sloths, and many other spectacular large animals that are no longer with us roamed the Earth. These animals are regarded as “Pleistocene megafauna,” named for the geological era in which they lived—also known as the Ice Age. In Vanished Giants: The Lost World of the Ice Age, paleontologist Anthony J. Stuart explores the lives and environments of these animals, moving between six continents and several key islands. Stuart examines the animals themselves via what we’ve learned from fossil remains, and he describes the landscapes, climates, vegetation, ecological interactions, and other aspects of the animals’ existence. Illustrated throughout, Vanished Giants also offers a picture of the world as it was tens of thousands of years ago when these giants still existed. Unlike the case of the dinosaurs, there was no asteroid strike to blame for the end of their world. Instead, it appears that the giants of the Ice Age were driven to extinction by climate change, human activities—especially hunting—or both. Drawing on the latest evidence provided by radiocarbon dating, Stuart discusses these possibilities. The extinction of Ice Age megafauna can be seen as the beginning of the so-called Sixth Extinction, which is happening right now. This has important implications for understanding the likely fate of present-day animals in the face of contemporary climate change and vastly increasing human populations.

Where Song Began by Tim Low Pdf

An authoritative and entertaining exploration of Australia’s distinctive birds and their unheralded role in global evolution Renowned for its gallery of unusual mammals, Australia is also a land of extraordinary birds. But unlike the mammals, the birds of Australia flew beyond the continent’s boundaries and around the globe many millions of years ago. This eye-opening book tells the dynamic but little-known story of how Australia provided the world with songbirds and parrots, among other bird groups, why Australian birds wield surprising ecological power, how Australia became a major evolutionary center, and why scientific biases have hindered recognition of these discoveries. From violent, swooping magpies to tool-making cockatoos, Australia’s birds are strikingly different from birds of other lands—often more intelligent and aggressive, often larger and longer-lived. Tim Low, a renowned biologist with a rare storytelling gift, here presents the amazing evolutionary history of Australia’s birds. The story of the birds, it turns out, is inseparable from the story of the continent itself and also the people who inhabit it.

Made in Africa by Steve Webb Pdf

Made in Africa: Hominin Explorations and the Australian Skeletal Evidence describes and documents the largest collection of modern human remains in the world from its time period. These Australian fossils, which represent modern humans at the end of their great 20,000 km journey from Africa, may be reburied in the next two years at the request of the Aboriginal community. Part one of the book provides an overview of modern humans, their ancestors, and their journeys, explores the construct of human evolution over the last two and half million years, and defines the background to the first hominins and later modern humans to leave Africa, cross the world and meet other archaic peoples who had also travelled and undergone similar evolutionary pathways. Part two focuses on Australia and the evidence for its earliest people. The Willandra Lakes fossils represent the earliest arrivals and are the largest and most diverse late Pleistocene collection from this part of the world. Although twenty to twenty-five thousand years younger than the oldest archaeological site in Australia, they exemplify the migrating end-point of the human story that reflect a diversity and culture not recorded elsewhere in the world. Part three records the Willandra Lake Collection itself from a photographic and descriptive perspective. Evolutionary biologists and geneticists will find this book to be a valuable documentation of the 20,000 km hominid migration from Africa to the most distant parts of the world, and of the challenges and findings of the Willandra Lake Collection. Provides perspective for dispersal of the earliest hominins from Africa and the possible routes they took Describes both the evolutionary development and demographic exit of intermediate and modern humans from Africa and incorporates the final stages of modern human migrations Provides a full documentation of the Willandra Lakes skeletal collection and its place in developing a picture of the earliest as well as later Aboriginal Australians

The Evolution of Dasyurid Marsupials by Carey Krajewski,Patricia A... Woolley,Michael Westerman Pdf

The marsupial family Dasyuridae has a history of study extending from 18th century naturalists to the modern genomics era. The Evolution of Dasyurid Marsupials: Systematics and Family History tells the story of dasyurid evolution as it unfolded in the context of changing world views on biodiversity, biotic history and scientific methodology, from its roots in Enlightenment taxonomy to its transformation by the Darwinian and Hennigian revolutions, and then its maturation as statistical phylogenetics and phylogenomics. Research on dasyurids includes every major approach in animal systematics, including some for which few comparable examples exist. It extends beyond the recent consensus on species relationships to include the timing of diversification, historical biogeography and the evolution of key phenotypic traits. This book introduces readers to living and fossil dasyurids, the questions evolutionary biologists have asked about them, the inferential methods used to answer those questions and the implications of those answers for understanding the history of this fascinating marsupial family. It offers a comprehensive synthesis of dasyurid evolutionary biology for students, teachers and researchers in mammalian evolution and marsupial biology.

American Megafaunal Extinctions at the End of the Pleistocene by Gary Haynes Pdf

The volume contains summaries of facts, theories, and unsolved problems pertaining to the unexplained extinction of dozens of genera of mostly large terrestrial mammals, which occurred ca. 13,000 calendar years ago in North America and about 1,000 years later in South America. Another equally mysterious wave of extinctions affected large Caribbean islands around 5,000 years ago. The coupling of these extinctions with the earliest appearance of human beings has led to the suggestion that foraging humans are to blame, although major climatic shifts were also taking place in the Americas during some of the extinctions. The last published volume with similar (but not identical) themes -- Extinctions in Near Time -- appeared in 1999; since then a great deal of innovative, exciting new research has been done but has not yet been compiled and summarized. Different chapters in this volume provide in-depth resumés of the chronology of the extinctions in North and South America, the possible insights into animal ecology provided by studies of stable isotopes and anatomical/physiological characteristics such as growth increments in mammoth and mastodont tusks, the clues from taphonomic research about large-mammal biology, the applications of dating methods to the extinctions debate, and archeological controversies concerning human hunting of large mammals.

The Pure State of Nature by David Horton Pdf

'Aborigines did not cause the extinction of the megafauna . . . and it is unlikely that they have caused the extinction of any element of the fauna and flora.' 'If you want to practise control burning in order to protect houses or farms, then do it in the same way as you would use a bulldozer to clear a firebreak, but don't pretend that you are doing anything but damage to the environment.' 'If you commercialise an environmental resource you do so to make money. Don't pretend that it also benefits the environment.' Spanning fifty thousand years and an entire continent, The Pure State of Nature presents a passionate account of the Australian environment. The myths that abound in popular and scientific writing, the 'theories' and fancies about the place of humans in the ecology of this vast landmass, are subjected to scrutiny. In particular, the author demolishes the widely accepted orthodoxy about the use of fire by Aborigines and their supposed part in the extinction of the Australian megafauna. From the ruins of those myths The Pure State of Nature offers lessons for the new millennium. In turns provocative, humorous, impassioned and gentle, this is a bold book of ideas about the past and present, a book about how we can shape the future. To The Pure State of Nature Dr David Horton brings many years' experience as scientist, farmer and archaeologist. Among his publications are Recovering the Tracks and The Encyclopaedia of Aboriginal Australia. He now writes and consults from his stud sheep farm in New South Wales.

Once and Future Giants by Sharon Levy Pdf

Until about 13,000 years ago, North America was home to a menagerie of massive mammals. Mammoths, camels, and lions walked the ground that has become Wilshire Boulevard in Los Angeles and foraged on the marsh land now buried beneath Chicago's streets. Then, just as the first humans reached the Americas, these Ice Age giants vanished forever. In Once and Future Giants, science writer Sharon Levy digs through the evidence surrounding Pleistocene large animal ("megafauna") extinction events worldwide, showing that understanding this history--and our part in it--is crucial for protecting the elephants, polar bears, and other great creatures at risk today. These surviving relatives of the Ice Age beasts now face the threat of another great die-off, as our species usurps the planet's last wild places while driving a warming trend more extreme than any in mammalian history. Deftly navigating competing theories and emerging evidence, Once and Future Giants examines the extent of human influence on megafauna extinctions past and present, and explores innovative conservation efforts around the globe. The key to modern-day conservation, Levy suggests, may lie fossilized right under our feet.

Quarterly Essay 48 After the Future by Tim Flannery Pdf

Australia is home to many animals and plants found nowhere else on earth, making Australians caretakers of a unique heritage in a land that tolerates few mistakes. Yet, in After the Future, Tim Flannery shows that this country is now on the brink of a new wave of extinctions, which threatens to leave our national parks as “marsupial ghost towns.” Why are species becoming extinct despite the tens of millions of dollars being spent to protect nature? And what more should be done? In this passionate and illuminating essay, Flannery tells the story of the human impact on the continent. He revisits his Future Eaters hypothesis, discussing how firestick farming helped to shape the ecology and preserve native fauna. He looks at the way recent governments, in tandem with an indifferent populace and a rabid libertarian right, have let environmental knowledge and commitments erode. Finally, he describes new approaches to wildlife conservation and argues that Australia must take the lead on these. This is an essay that rings the alarm on behalf of the natural world, and asks us to think again about protection of its irreplaceable riches. ‘Such is the depth of public ignorance about Australia’s extinction crisis that most people are unaware that it is occurring, while those who do know of it commonly believe that our national parks and reserves are safe places for threatened species. In fact the second extinction wave is now in full swing, and it’s emptying our national parks and wildlife reserves as ruthlessly as other landscapes.’ —Tim Flannery, After the Future ‘Flannery is known as a passionate advocate for conservation, but rarely has he sounded so angry.’ —Fiona Capp, Sydney Morning Herald ‘He's a scientist of world standing, a prolific and bestselling writer, a noted explorer, passionate about the Australian environment, and believes global warming is a calamitous crisis facing us all. Tim Flannery is also a controversial, outspoken stirrer who promises ... to tread on toes if he has to, to get his blunt views across.’ –Kerry O'Brien, The 7:30 Report
