But there was a time when people hunted the otters almost to extinction. Without sea otters to eat them, an army of hungry sea urchins grew and destroyed entire kelp forests. Fish and other animals that depended on the kelp were lost, too. But when people protected the sea otters with new laws, their numbers began to recover, and so did the kelp forests. Susannah Buhrman-Deever offers a beautifully written account of a trophic cascade, which happens when the removal of a single element affects an entire habitat. Asides that dig deeper are woven throughout Matthew Trueman’s dynamic illustrations, starring a raft of charismatic sea otters. Back matter includes more information about sea otters and kelp forests, including their importance and current status, the effects of the international fur trade on indigenous peoples, and a list of books and websites for readers who wish to continue to explore.

    The final spread will open up into a gatefold showing a photograph of the full Titanosaur skeleton on display at the museum. Chock-full of back matter like a glossary and extra information and photographs from the dig, and an inside jacket poster of the Titanosaur, kids of all ages will devour this book.

    He gave her a scientific education, which was highly unusual for women and girls in the early 19th century. Fascinated with the plant life around her, Anna became a botanist. She recorded all her findings in detailed illustrations and engravings, until the invention of cyanotype photography in 1842. Anna used this new technology in order to catalogue plant specimens—a true marriage of science and art. In 1843, Anna published the book Photographs of British Algae: Cyanotype Impressions with handwritten text and cyanotype photographs. It is considered the first book of photographs ever published. Weaving together histories of women, science, and art, The Bluest of Blues will inspire young readers to embark on their own journeys of discovery and creativity.

     In Elkhorn Slough, an inlet on the California coast, seagrass grows healthy and strong in the shallow water. This healthy seagrass baffled marine biologist Brent Hughes. The scientist expected this estuary to be overrun with algae, causing the seagrass to die. Why was the seagrass thriving? As Brent investigated, signs pointed to an unexpected player helping to keep the seagrass healthy: sea otters! What do these top predators have to do with an aquatic grass at the opposite end of the food chain? Brent's discovery gave scientists insight into the delicate balance of ecosystems. Follow science in action as Brent conducts the research that led to this major discovery.

    Because she was going to study him, she decided to call him Alex--short for Avian Learning EXperiment. At that time, most scientists thought that the bigger the brain, the smarter the creature; they studied great apes and dolphins. African greys, with their walnut-sized "birdbrains," were pretty much ignored--until Alex. His intelligence surprised everyone, including Irene. He learned to count, add, and subtract; to recognize shapes, sizes, and colors; and to speak, and understand, hundreds of words. These were things no other animal could do. Alex wasn't supposed to have the brainpower to do them, either. But he did them anyway.Accompanied by Meilo So's stunning illustrations, Alex and Irene's story is one of groundbreaking discoveries about animal intelligence, hard work, and the loving bonds of a unique friendship.
