Showing results for "The Past" in Biological Sciences

In Origins, Frank H. T. Rhodes explores the origin and evolution of living things, the changing environments in which they have developed, and the challenges we now face on an increasingly crowded and polluted planet. Rhodes argues that the future well-being of our burgeoning population depends in no small part on our understanding of life's past, its long and slow development, and its intricate interdependencies.

Jeffrey W. Martz of the Denver Museum of Nature and Science is widely renowned for his expertise in the field of paleontology, a science that lies at the crossroads of biology and geology. Paleontologists seek to unearth and re-create life hundreds of millions of years old, and the work of paleontologists offers us detailed glimpses of the prehistoric world. These fascinating lectures delve into the techniques and processes of paleontologists while providing a better understanding of this often misunderstood science.

This original, topical and engaging book navigates the complex realm of forest restoration. It reveals how a nuanced approach is required – one that integrates the latest scientific advancements (for instance in microbial ecology, acoustic technology and epigenetics), Indigenous leadership and a holistic understanding of the interconnectedness of life within these vital ecosystems.

Twelve Trees introduces us to a dozen species of trees that epitomize the challenges facing the planet, and the ways that scientists and others are working with a growing sense of urgency to save them. Scientists, ethnobotanists, indigenous peoples, and collectives of all kinds are studying trees and their workings, using a host of new tools, to learn how trees function individually and collectively, and why they do what they do.

From the secret fossils of London to the three-billion-year-old rocks of the Scottish Highlands, and from state-of-the-art Californian laboratories to one of the world's most dangerous volcanic complexes hidden beneath the green hills of western Naples, set out on an adventure to those parts of the world where the Earth's life-story is written into the landscape. Helen Gordon turns a novelist's eye on the extraordinary scientists who are piecing together this planetary drama.

The fascinating group of animals called dinosaurs became extinct some 65 million years ago (except for their feathered descendants). In their place evolved an enormous variety of land creatures, especially mammals, which in their way were every bit as remarkable as their Mesozoic cousins. The Age of Mammals, the Cenozoic Era, has never had its Jurassic Park, but it was an amazing time in earth's history, populated by a wonderful assortment of bizarre animals. The rapid evolution of thousands of species of mammals brought forth many incredible creatures—including our own ancestors.

Madagascar is a place of change. A biodiversity hotspot and the fourth largest island on the planet, it has been home to a spectacular parade of animals, from giant flightless birds and giant tortoises on the ground, to agile lemurs leaping through the treetops. Some species live on, many have vanished in the distant or recent past. Over vast stretches of time, Madagascar’s forests have expanded and contracted in response to shifting climates and the hand of people is clear in changes during the last 1,000 years or so.

Whales are among the largest, most intelligent, deepest diving species to have ever lived on our planet. We have hunted them for thousands of years and scratched their icons into our mythologies. They simultaneously fill us with waves of terror, awe and affection - yet we know hardly anything about them. Whales tend to enter our awareness only when they die, struck by a ship or stranded in the surf. They evolved from land-roaming, doglike creatures into animals that move like fish and breathe like us and can grow to 300,000 pounds, live 200 years and roam entire ocean basins. Yet despite centuries of observing whales, we know little about their evolutionary past.

More than 10,000 years ago spectacularly large mammals roamed the pampas and jungles of South America. This book tells the story of these great beasts during and just after the Pleistocene, the geological epoch marked by the great ice ages. Megafauna describes the history and way of life of these animals, their comings and goings, and what befell them at the beginning of the modern era and the arrival of humans.

Bears have always held a central place in our collective memory, from Indigenous folklore and Greek mythology to nineteenth-century fairytales and the modern toy shop. But as humans and bears come into ever-closer contact, our relationship nears a tipping point. Today, most of the eight remaining bear species are threatened with extinction. Some, such as the panda bear and the polar bear, are icons of the natural world; others, such as the spectacled bear and the sloth bear, are far less known.

It is rare for life to change Earth, yet three organisms have profoundly transformed our planet over the long course of its history. Elemental reveals how microbes, plants, and people used the fundamental building blocks of life to alter the climate, and with it, the trajectory of life on Earth in the past, present, and future. Taking listeners from the deep geologic past to our current era of human dominance, Stephen Porder focuses on five of life’s essential elements—hydrogen, oxygen, carbon, nitrogen, and phosphorus.

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.

This volume, aimed at the general audience, presents life and times of the amazing animals that inhabited Earth more than 500 million years ago. The Cambrian Period was a critical time in Earth's history. During this immense span of time nearly every modern group of animals appeared. Although life had been around for more than 2 million millennia, Cambrian rocks preserve the record of the first appearance of complex animals with eyes, protective skeletons, antennae, and complex ecologies.

The characters in Tasting the Past include a young Swiss scientist who set out to decode the DNA of every single wine grape in the world; Middle Eastern researchers who seek to discover the wines that King David drank; and a University of Pennsylvania academic who has spent decades analyzing wine remains. The science illuminates wine in ways no critic can, and demolishes some of the most sacred dogmas of the industry: well-known French grapes aren't especially noble.

We do not see the ocean when we look at the water that blankets more than two thirds of our planet. We only see the entrance to it. Beyond that entrance is a world hostile to humans, yet critical to our survival. The first divers to enter that world held their breath and splashed beneath the surface, often clutching rocks to pull them down. Over centuries, they invented wooden diving bells, clumsy diving suits, and unwieldy contraptions in attempts to go deeper and stay longer.

With the lucid verve and solid scientific grounding of an Oliver Sacks or Malcolm Gladwell, Dr. Brian Boxer Wachler guides listeners on a fascinating tour of the bedrock of our existence - the way our senses perceive everything and everyone in the world around us. Why does one person see Jesus in a shower curtain, get a "bad feeling" about someone they've just met, or hear a conversation so differently than the other person? Boxer Wachler describes some of the mysterious medical conditions that cause non-psychiatric hallucinations and neurological mix-ups.

How is it that we came to be here? The search for answers to that question has preoccupied humans for millennia. Scientists have sought clues in the genes of living things; in the physical environments of Earth, from mountaintops to the depths of the ocean; in the chemistry of this world and those nearby; in the tiniest particles of matter; and in the deepest reaches of space. In Islands of the Cosmos, Dale A. Russell traces a path from the dawn of the universe to speculation about our future on this planet.
