Once and Future Giants

once and future giants levy sharon

Having set up humans as the likely contributions tomegafaunal decline, Levy goes on to discuss the role of herbivore megafauna in seed germination and dispersal. The following two chapters review parallels between theecology of modern elephants and the suspected ecology ofwoolly mammoths, read from mammoth tusks and tracks. 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. 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. Mammoths, camels, and lions walked the ground that has become our cities and streets. Critics, including biologists enmeshed in the struggle to restore native species like the gray wolf and the bison, see the proposal as a dangerous distraction from more realistic and legitimate conservation efforts.

The theorythat Pleistocene megafaunal extinctions are a result ofhuman hunting is crucial to Levys later arguments aboutthe lessons we can learn for conservation. Then, just as the first humans reached the Americas, these Ice Age giants vanished forever. We meet reintroductions advocated for reindeer, musk-ox, horse and bison in other northern climes and some ambitious plans for Siberia at least they still have wolves and occasional tigers. Levy devotes surprisingly little pagespace to Sergei Zimovs Pleistocene Park in NortheasternSiberian. The key to modern-day conservation, Levy suggests, may lie fossilized right under our feet. Using the example of theaccidental introduction of the Dingo in Australia, Levypresents evidence that only the presence of carnivores inthe landscape can stabilize ecosystems and produce the mostbiodiverse areas. Throughout,interesting and varied examples of prehistoric and contempo-rary megafaunal are given.

Once and Future Giants Audiobook

This is a fascinating read, exploring the changing landscapes of an Ice Age and post-Ice Age planet, mostly from the perspective of the megaherbivores. A recent paper in Conservation Biology Oliviera-Santosand Fernandez 2010 brings up some of the more seriousproblems associated with rewilding. Biologist and journalist Sharon Levy lays out the evidence for this theory--and explores what this species drain can teach us now. If North America was re-wilded, the ecosystem would be more in balance. These chapters conclude that mammoth decline was mostlikely due to increased human hunting pressure.

She is a contributing editor at OnEarth magazine and writes regularly for National Wildlife, BioScience, and New Scientist. In general, the book has aNorth American focus, both in terms of the location of casestudies and academics whose work are included, reflectingboth the nationality of the writer and the location of the mostheated debates over Pleistocene rewilding. The patterns and consequences of the Pleistocene die-offs can help us to predict how landscapes will change if we lose big mammals, and help us to spot warning signs of impending extinctions. Until about 13, 000 years ago, North America was home to a menagerie of massive mammals. 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 book may lose readers who are unconvinced aboutthe role of humans in Pleistocene extinctions, or about themethods used to infer past ecological conditions. 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. Thewidest appeal of this book will be for members of thegeneral public, or academics whose areas of research areoutside the topics tackled in the book. Although originally proposed to protect thesespecies, this law may mean that interventions which couldsave a species are not implemented. 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.

Paul Martin, by studying Ground Sloth poop, saw there was evidence for climatic change. Critics, including biologists enmeshed in the struggle to restore native species like the gray wolf and the bison, see the proposal as a dangerous distraction from more realistic and legitimate conservation efforts. Levy ends her book with a call to engage with megafau-na, its management and conservation. The majority of theideas presented in this book are not new, but they arepackaged in a very readable, straightforward format. However, I thinkthe most important sections of this book relate to the modernday applications of the hypotheses and theories this infor-mation may suggest.

Then, just as the first humans reached the Americas, these Ice Age giants vanished forever. But the big question is whether we can reverse these trends. Until about 13,000 years ago, North America was home to a menagerie of massive mammals. These surviving relatives of the Ice Age beasts now face an intensified replay of that 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. Until about 13,000 years ago, North America was home to a menagerie of massive mammals. And elephants — dreamers talking of replacing those lost Columbian mastodons with African elephants in continental America, letting them roam over the rangelands and start rebuilding older, richer ecosystems.

Pleistocene rewilding involves introduc-ing species to new areas, where they could become invasiveand upset existing balances. Buy Once and Future Giants by Sharon Levy from Australia's Online Independent Bookstore, Boomerang Books. Pleistocene rewilding however, is far more controversial. Fascinating, rich and readable it gives the reader a lot to think about, discussions to have and arguments to pursue — if only with oneself! New York: Oxford University Press, 2013.

Once And Future Giants: book review

once and future giants levy sharon

Declines of angiosperms in soil cores,followed by extreme burning events, are indicative of a declinein large herbivores. Octavo, paperback, black and white photographs. Then, just as the first humans reached the Americas, these Ice Age giants vanished forever. That could mean returning lost species to familiar landscapes — beavers or moose in Britain, perhaps. Theapplied management ideas expounded in this book are rel-atively established in conservation. Inspired by a passion for the lost Pleistocene giants, some scientists advocate bringing elephants and cheetahs to the Great Plains as stand-ins for their extinct native brethren. 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.

This pattern in soil cores, states Levy, isrepeated just after the first arrival of humans worldwide. In the final sections of the book, the implications of theevidence presented for conservation is discussed. She is a contributing editor at OnEarth magazine and writes regularly for National Wildlife, BioScience, and New Scientist. Large, but not a giant, it still trundles in as the biggest herbivore in its small world and has enthusiastic champions among ranchers and environmentalists. 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. This issue is something whichis partially addressed by Levy, but a problem which shouldact as a major barrier for Pleistocene rewilding. And we step straight into Australian controversy with camels and water buffalo possibly replacing lost marsupial giant kangaroos and wombats in tandem with Native Australian fire-setting regimes.
