What is the difference between a savanna and a prairie? How do bison, zebras, and other grazers avoid hungry grassland predators? Trek across the plant-covered landscape of this book, and find out what makes grasslands one of Earth's treasures.

Deciduous forest ecosystems can be found on nearly every continent. Countless animals and plants live in them. So what difference could the loss of one animal species make? Follow the chain reaction, and discover how important gray wolves are.

This audiobook names and describes the offspring of a cow, horse, sheep, goat, pig, chicken, goose, and turkey.

This audiobook names and describes the offspring of a squirrel, toad, woodpecker, wolf, opossum, bear, mouse, and whitetail deer.

Sharks are some of the most fascinating and ecologically important, yet most threatened and misunderstood animals on Earth. More often feared than revered, their role as predators of the deep has earned them a reputation as a major threat to humans. But the truth is that sharks are not a danger to us—they’re in danger from us. In Why Sharks Matter, marine conservation biologist Dr. David Shiffman urges us to overcome our misconceptions and embrace sharks as the imperiled and elegant ocean guardians they really are.

As one of the world’s leading field biologists, George Schaller has spent much of his life traversing wild and isolated places in his quest to understand and conserve threatened species - from mountain gorillas in the Virunga to pandas in the Wolong and snow leopards in the Himalaya. Throughout his celebrated career, Schaller has spent more time in Tibet than in any other part of the world, devoting more than thirty years to the wildlife, culture, and landscapes that captured his heart and continue to compel him.

Si les plantes ne peuvent pas se déplacer, elles sont capables de conquérir les terres les plus lointaines, les zones les plus inaccessibles et les régions les moins hospitalières. Génération après génération, grâce à leurs spores ou leurs graines, les végétaux se déplacent et conquièrent de nouveaux espaces.

Having access to natural, green spaces is vital to our physical and mental wellbeing. But, as urban development spreads, grey has become the new green. Already, concrete outweighs every tree, bush and shrub on Earth. Nature deprivation is a fast-growing epidemic, harming the health and happiness of hundreds of millions of people worldwide—especially vulnerable and marginalized groups.

Water scarcity is on everyone's mind. Long taken for granted, water availability has entered the realm of economics, politics, and people's food and lifestyle choices. But as anxiety mounts - even as a swath of California farmland has been left fallow and extremist groups worldwide exploit the desperation of people losing livelihoods to desertification - many are finding new routes to water security with key implications for food access, economic resilience, and climate change.

Follow along with this class as they explore a creek near their school in Pennsylvania! They want to learn about the water and its ecosystem, so they perform a survey to determine its quality and biota. What do you think they will find?

The Steller's sea cow, a cousin to the manatee, was hunted to extinction just 27 years after it was discovered. Another century passed before humans realized the need to preserve endangered species. Today scientists are working to ensure its cousin, the Florida manatee, doesn’t meet the same fate.

Learn about America's founding conservationists: Theodore Roosevelt, Gifford Pinchot, Stephen T. Mather, Hugh Hammond Bennett.

Here's how a few pioneers forged their own unique paths in the conservation movement.

The remarkable story of the heroic effort to save and preserve Afghanistan's wildlife - and a culture that derives immense pride and a sense of national identity from its natural landscape.

In an age of unprecedented exploration and innovation, our oceans remain largely unknown, and endlessly fascinating: full of mystery, danger, beauty, and inspiration. Bill Streever - a longtime deep-sea diver himself - has masterfully woven together the science and history of Earth's last remaining frontier: the sea.

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.

Written by a marine scientist (and winner of French eloquence competitions), this work of narrative nonfiction blends Bill François’ personal story with that of sea creatures to create an original and exciting work. In poetic prose, he describes his unlikely journey from being a Parisian child, afraid of the water and crippled by self-consciousness, to an eloquent and self-assured young man with a passion for the ocean and all who inhabit it.

Simple science text gives a close-up account of the fascinating world of the dung beetle. When an animal lightens its load, dung beetles race to the scene. They battle over, devour, hoard, and lay their eggs in the precious poop. Dung is food, drink, and fuel for new life - as crucial to these beetles as the beetles are to many habitats, including our own.
