David Brin’s Uplift novels—Sundiver, Hugo award winner The Uplift War, and Hugo and Nebula winner Startide Rising—are among the most thrilling and extraordinary science fiction tales ever written. Now David Brin returns to this future universe for a new Uplift trilogy, packed with adventure, passion and wit. The planet Jijo is forbidden to settlers, its ecology protected by guardians of the Five Galaxies. But over the centuries it has been resettled, populated by refugees of six intelligent races. Together they have woven a new society in the wilderness, drawn together by their fear of Judgment Day, when the Five Galaxies will discover their illegal colony. Then a strange starship arrives on Jijo. Does it bring the long-dreaded judgment, or worse—a band of criminals willing to destroy the six races of Jijo in order to cover their own crimes?

What is life like in a coral reef? What do corals eat? Why are corals more colorful at nighttime? Learn about some of the most beautiful locations in the natural world Marine biologists believe coral reefs existed 400 million years ago, when dinosaurs roamed the earth. Today this active environment is home to about 20,000 kinds of brilliantly colored corals, plants, and animals--more sea creatures than are found anywhere else in the world. The Great Barrier Reef in Australia is so large that astronauts can see it from outer space! Children in early elementary grades will enjoy Gibbon's informative text and clear, detailed illustrations on this journey into the unique lives of coral reefs.

Takes children to the underwater world of Australia's Great Barrier Reef for a prime example of how a complex ecosystem depends on its keystone species. Sharon Wismer—reef ecologist and mom—is the best tour guide a kid could have for a visit to the underwater world of Australia’s Great Barrier Reef. Alice Wong’s richly detailed, accurate watercolors take a boy and girl snorkeling to see the fishes that maintain the ecological balance between the corals and their main competitor, algae. Without the fish species that brush, crop, scrape, excavate, and browse the algae, coral reefs would die. A coral reef is a brilliant and colorful example of how a complex ecosystem functions and why its keystone species are critical to its health. The Great Barrier Reef is one of Earth’s most celebrated natural treasures. Here children discover why the reef is threatened and what we can all do to help protect it. Endorsements are coming from Charlie Veron (“the godfather of coral,” featured in the 2017 film Chasing Coral) and David Bellwood, a world-renowned reef fish ecologist whose lab is the source of much of the information in this book. Keepers of Reef is the rare children’s book combining cutting-edge science with narrative and pictorial magic. Thorough backmatter sources and resources are included.

Following the cycle of life from the animals' point of view, this new series approaches the natural world in a completely unique way.
