Available in PDF, EPUB and Kindle. Book excerpt: From the fiercest predator to the lowliest plant, every member of an ecosystem is immeasurably important to the survival of their environment. Although they're not regarded as a keystone species, sea urchins play a pivotal role in maintaining healthy marine environments. Without sea urchins to consume algae, entire coral reef ecosystems could collapse. This educational text invites readers to imagine a world without sea urchins, delving into curricular science concepts, such as interdependence of species, with accessible language and real-world examples.
Download or read book What If Sea Otters Disappeared written by Theresa Emminizer and published by Gareth Stevens Publishing LLLP. This book was released on 2019-07-15 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sea otters are a keystone species in their environment. If they were to disappear, the ripple effect on the plants and animals in the ecosystem would be profound. Kelp forests absorb carbon dioxide. Sea urchins feed on kelp and can deplete these forests if they are not kept in check. Sea otters prey on sea urchins, helping to maintain healthy kelp forests and thus, a healthy ecosystem. This dynamic text engages readers in an educational dialogue, examining the role of sea otters, the threats they face, and possible solutions to protect this fundamental species.

Download or read book Sea Urchins written by Michael Rajczak and published by Gareth Stevens Publishing LLLP. This book was released on 2015-07-15 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spiny, small, and edible, sea urchins are found in oceans all over the world. Their spines can be long or short and can cause great injury in their own right. In addition, some sea urchins’ spines are venomous. Divers are familiar with how to deal with a sea urchin sting, and readers will be, too. From why sea urchins sting to the rest of their body structures, this volume’s science content gives a great overview of this fascinating creature. Full-color photographs take readers into the ocean to see sea urchins up close—but not close enough that they’ll get stung.

Download or read book Homewaters written by David B. Williams and published by University of Washington Press. This book was released on 2021-04-24 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Not far from Seattle skyscrapers live 150-year-old clams, more than 250 species of fish, and underwater kelp forests as complex as any terrestrial ecosystem. For millennia, vibrant Coast Salish communities have lived beside these waters dense with nutrient-rich foods, with cultures intertwined through exchanges across the waterways. Transformed by settlement and resource extraction, Puget Sound and its future health now depend on a better understanding of the region’s ecological complexities. Focusing on the area south of Port Townsend and between the Cascade and Olympic mountains, Williams uncovers human and natural histories in, on, and around the Sound. In conversations with archaeologists, biologists, and tribal authorities, Williams traces how generations of humans have interacted with such species as geoducks, salmon, orcas, rockfish, and herring. He sheds light on how warfare shaped development and how people have moved across this maritime highway, in canoes, the mosquito fleet, and today’s ferry system. The book also takes an unflinching look at how the Sound’s ecosystems have suffered from human behavior, including pollution, habitat destruction, and the effects of climate change. Witty, graceful, and deeply informed, Homewaters weaves history and science into a fascinating and hopeful narrative, one that will introduce newcomers to the astonishing life that inhabits the Sound and offers longtime residents new insight into and appreciation of the waters they call home.

Download or read book If You Take Away the Otter written by Susannah Buhrman-Deever and published by National Geographic Books. This book was released on 2020-05-26 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: When the sea otters disappear, why does their kelp forest habitat disappear, too? On the Pacific Coast of North America, sea otters play, dive, and hunt for sea urchins, crabs, abalone, and fish in the lush kelp forests beneath the waves. 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.
Download or read book What Bugged the Dinosaurs written by George Poinar Jr. and published by Princeton University Press. This book was released on 2010-01-01 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: Millions of years ago in the Cretaceous period, the mighty Tyrannosaurus rex--with its dagger-like teeth for tearing its prey to ribbons--was undoubtedly the fiercest carnivore to roam the Earth. Yet as What Bugged the Dinosaurs? reveals, T. rex was not the only killer. George and Roberta Poinar show how insects--from biting sand flies to disease-causing parasites--dominated life on the planet and played a significant role in the life and death of the dinosaurs. The Poinars bring the age of the dinosaurs marvelously to life. Analyzing exotic insects fossilized in Cretaceous amber at three major deposits in Lebanon, Burma, and Canada, they reconstruct the complex ecology of a hostile prehistoric world inhabited by voracious swarms of insects. The Poinars draw upon tantalizing new evidence from their amazing discoveries of disease-producing vertebrate pathogens in Cretaceous blood-sucking flies, as well as intestinal worms and protozoa found in fossilized dinosaur excrement, to provide a unique view of how insects infected with malaria, leishmania, and other pathogens, together with intestinal parasites, could have devastated dinosaur populations. A scientific adventure story from the authors whose research inspired Jurassic Park, What Bugged the Dinosaurs?? offers compelling evidence of how insects directly and indirectly contributed to the dinosaurs' demise.
