    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.

    Here comes Sgt. Stubby! That German shepherd star of the silver screen may have been born behind enemy lines during World War I, but Stubby, the stump-tailed terrier, worked behind enemy lines, and gained military honors along the way. Private Robert Conroy casually adopted the orphan pup while attending basic training on the campus of Yale University in 1917. The Connecticut volunteer never imagined that his stray dog would become a war hero. He just liked the little guy. When Conroy's unit shipped out for France, he smuggled his new friend aboard. By the time Stubby encountered Conroy's commanding officer, the dog had perfected his right-paw salute. Charmed, the CO awarded Stubby mascot status and sent him along with Conroy's unit to the Western Front. Stubby's brave deeds earned him a place in history and in the Smithsonian Institution where his stuffed body can still be seen. Almost 100 years later, Stubby's great deeds and brave heart make him an animal hero to fall in love with and treasure all over again.

    Millipedes do it. Dinosaurs did it. You do it: I do it. Octopuses don't (and nor do octopi). Spiders might do it: more research is needed. Birds don't do it, but they could if they wanted to. Herrings do it to communicate with each other. At the beginning of 2017, an innocent question on twitter about snakes formed the hashtag #doesitfart and spread pungently across the internet - and major newspapers - as dozens of experts weighed in on which animals do and don't fart, and if they do, how much, how often, what it's made of, what it smells like, and what it's for. Does it Fart? is the result: the fully authoritative, fully illustrated guide to animal flatulence, covering the habits of 80 animals in more detail than you ever knew you needed. What foods make hyena farts smell especially bad? What is a fossa, and does it fart? Why do clams vomit but not fart? What is a fart, anyway? With contributions from dozens of biologists, Does it Fart? is a book that will allow you to shift the blame onto all kinds of unlikely animals for years to come.

    Thanks to forensics—the science of examining physical evidence—we now know that King Tut died of malaria. We also know that stomach cancer, and not arsenic as suspected, killed Napoleon. Seven intriguing stories about historical royal figures whose demise was suspicious, and hard scientific facts about crime-solving techniques make each event seem like an episode of CSI rather than a history lesson. Kids will be fascinated to find out how scientists use autopsy results, DNA testing, bone fragments, and even insects to determine the cause of death. At times a gripping whodunit, at others an exercise in deductive reasoning, this book will be hard to put down for any kids who love mysteries, murder, and suspense.

    Using the typical contents of a child's school backpack (defined as water, food, clothing, paper, plastic, metals, electronics), this book explores those stages in detail, including lots of ways to reduce, reuse or recycle waste along the way. Children will gain new insight into the routine decisions they make about their own consuming and trashing or recycling practices. For example: How long does it take for a cotton T-shirt to decompose in a landfill? Can a bike helmet be made from recyclable materials? Which is better for the Earth, wrapping a sandwich in aluminum foil or plastic? By learning to use critical thinking skills to make informed choices, children will feel empowered by the important, constructive role they can play in the future health of the planet. Author Erica Fyvie has found a way to use everyday objects to speak directly to children's curiosity and their desire to make a difference.

    Everywhere the House Sparrow went, it competed with humans for grain, becoming such a pest that in some places “sparrow catcher” became an actual job and bounties were paid to those who got rid of it.But not everyone hated the House Sparrow, and in 1852, fifty pairs were released in New York City. In no time at all, the bird had spread from coast to coast. Then suddenly, at the turn of the century, as cars took over from horses and there was less grain to be found, its numbers began to decline. As our homes, gardens, cities and farmland have changed, providing fewer nesting and feeding opportunities, the House Sparrow’s numbers have begun to decline again — though in England and Holland this decline appears to be slowing.
