Showing results for "Extinction" in Biological Sciences

Over the last half a billion years, there have been five mass extinctions of life on earth. Scientists around the world are currently monitoring the sixth, predicted to be the most devastating extinction event since the asteroid impact that wiped out the dinosaurs. Elizabeth Kolbert combines brilliant field reporting, the history of ideas and the work of geologists, botanists and marine biologists to tell the gripping stories of a dozen species – including the Panamanian golden frog and the Sumatran rhino – some already gone, others at the point of vanishing.

We live in an age of mass extinction. The earth's biodiversity is decreasing at a faster rate than ever. Industrial agriculture and the standardisation of taste are not only wiping out many edible plants but also the food cultures, histories and livelihoods that go with them. Inspired by a global project to collect and preserve foods that are at risk of extinction, Dan Saladino sets out to encounter these endangered foods.

In The Last Days of the Dinosaurs, Riley Black walks listeners through what happened in the days, the years, the centuries and the million years after the impact, tracking the sweeping disruptions that overtook this one spot, and imagining what might have been happening elsewhere on the globe. Picture yourself in the Cretaceous period. It's a sunny afternoon in the Hell Creek of ancient Montana 66 million years ago. In a matter of hours, everything here will be wiped away.

If you could bring back one living being from the whole of the history of time, what would you choose? Comedian and former stem-cell biologist Helen Pilcher has thought about this problem - a lot. In Bring Back the King, Helen explains the cutting-edge science that makes the resurrection of extinct animals a very real possibility and highlights her choices from eras gone by, from the king of the dinosaurs, Tyrannosaurus rex, to the King of Rock 'n' Roll, Elvis Presley.

In ‘Humans Are Doomed To Go Extinct’, an article in Scientific American published in November 2021, veteran Nature editor Dr Henry Gee predicted that Homo sapiens is on a rapid one-way ride to extinction. The article provoked media coverage and comment around the world. In The Decline and Fall of the Human Empire, Gee expands the themes of his much-discussed article to book length, charting both the rise as well as the fall of humans. Gee paints a picture of extinction within the next 10,000 years – and suggests ways that our exceptional species might avoid its fate.

In this Very Short Introduction, Paul B. Wignall looks at the causes and nature of extinctions, past and present, and the factors that can make a species vulnerable. Summarizing what we know about all of the major and minor extinction events, he examines some of the greatest debates in modern science, such as the relative role of climate and humans in the death of the Pleistocene megafauna, including mammoths and giant ground sloths, and the roles that global warming, ocean acidification, and deforestation are playing in present-day extinctions.

Learn about the nature of Extinction with iMinds insightful knowledge series. Extinction means the death of a species of animal or plant. When you think of extinct species, you probably think of dinosaurs. So it may amaze you to know that 99% of all species that once lived on the earth are now extinct!

A former endangered species biologist looks at the ongoing sixth mass extinction through the prism of human behavior, personal experience, ecology, evolutionary biology, and contemporary conservation efforts. He provides new insights into factors triggering the current mass extinction event and examines conventional wisdom regarding human intelligence. The author suggests—as humanity edges ever closer to disappearing forever—a clear-eyed, real-world rationale for resignation but also acceptance.

Many scientists believe that we are currently living through the Earth’s sixth mass extinction, with species disappearing at a rate not seen for tens of millions of years – a trend that will only accelerate as climate change and other pressures intensify. What does it mean to live in such a time? And what exactly do we lose when a species goes extinct? In Lost Wonders conservationist and science writer Tom Lathan tells the stories of ten species that have lived, died out and been declared extinct since the turn of the twenty-first century.

Palaeontologist Steve Brusatte weaves together the history and evolution of our mammal forebears with stories of the scientists whose fieldwork and discoveries underlie our knowledge, both of iconic mammals like the mammoths and sabre-toothed tigers of which we have all heard, and of fascinating species that few of us are aware of. For what we see today is but a very limited range of the mammals that have existed; in this fascinating and groundbreaking book, Steve Brusatte tells their—and our—story.

As recently as 11,000 years ago - "near time" to geologists - mammoths, mastodons, gomphotheres, ground sloths, giant armadillos, native camels and horses, the dire wolf, and many other large mammals roamed North America. In what has become one of science's greatest riddles, these large animals vanished in North and South America around the time humans arrived at the end of the last great ice age.

The great auk is one of the most tragic and documented examples of extinction. A flightless bird that bred primarily on the remote islands of the North Atlantic, the last of its kind were killed in Iceland in 1844. Gisli Pálsson draws on firsthand accounts from the Icelanders who hunted the last great auks to bring to life a bygone age of Victorian scientific exploration while offering vital insights into the extinction of species.

Speaking to experts in fields as diverse as oil production and ecology, and visiting the places that have escaped recent human activity to discover how they have adapted to life without us, Alan Weisman paints an intriguing picture of the future of Earth. Exploring key concerns of our time, this absorbing thought experiment reveals a powerful - and surprising - picture of our planet's future.

Insects are dying off at an apocalyptic rate, or are they? Now there's a way to find out. In this limited series, we go to a remote island rainforest to listen to sound-based research that could reveal the truth about global insect death.

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 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.

We are in the midst of an extinction event: the sixth mass extinction on Earth and one entirely caused by mankind. All species become extinct sooner or later, but we have accelerated that natural process several hundredfold, and now, it is happening right in front of our eyes. Extinction has a terrifying finality to it. And many species have already been lost to us forever; there is little we can do about that. What we can do, however, is reflect, remember, and ultimately acknowledge the unvarnished truth.

In its 4.5 billion–year history, life on Earth has been almost erased at least half a dozen times: shattered by asteroid impacts, entombed in ice, smothered by methane, and torn apart by unfathomably powerful megavolcanoes. And we know that another global disaster is eventually headed our way. Can we survive it? How?

As a species, Homo sapiens is at a crossroads. Study of our planet’s turbulent past suggests that we are overdue for a catastrophic disaster, whether caused by nature or by human interference.
It’s a frightening prospect, as each of the Earth’s past major disasters—from meteor strikes to bombardment by cosmic radiation—resulted in a mass extinction, where more than 75 percent of the planet’s species died out. But in Scatter, Adapt, and Remember, Annalee Newitz, science journalist and editor of the science Web site io9.com explains that although global disaster is all but inevitable, our chances of long-term species survival are better than ever. Life on Earth has come close to annihilation—humans have, more than once, narrowly avoided extinction just
during the last million years—but every single time a few creatures survived, evolving to adapt to the harshest of conditions.
This brilliantly speculative work of popular science focuses on humanity’s long history of dodging the bullet, as well as on new threats that we may face in years to come. Most important, it explores how scientific breakthroughs today will help us avoid disasters tomorrow. From simulating tsunamis to studying central Turkey’s ancient underground cities; from cultivating cyanobacteria for “living cities” to designing space elevators to make space colonies cost-effective; from using math to stop pandemics to studying the remarkable survival strategies of gray whales, scientists and researchers the world over are discovering the keys to long-term resilience and learning how humans can choose life over death.
Newitz’s remarkable and fascinating journey through the science of mass extinctions is a powerful argument about human ingenuity and our ability to change. In a world populated by doomsday preppers and media commentators obsessively forecasting our demise, Scatter, Adapt, and Remember is a compelling voice of hope. It leads us away from apocalyptic thinking into a future where we live to build a better world—on this planet and perhaps on others. Readers of this book will be equipped scientifically, intellectually, and emotionally to face whatever the future holds.

A comedy podcast about extinct stuff. Join Melissa & Jack as they attempt to uncover the natural histories of bygone creatures and other things.

Could extinct species, like mammoths and passenger pigeons, be brought back to life? The science says yes. In How to Clone a Mammoth, Beth Shapiro, evolutionary biologist and pioneer in "ancient DNA" research, walks listeners through the astonishing and controversial process of de-extinction.
