flowers, mosses, shrubs, and lichens. These hardy little plants transform the northern landscape, as they take advantage of the warmer weather and long hours of sunlight. Caribou, lemmings, snow buntings, and many other wildlife species depend on tundra plants for food and nutrition, but they are not the only ones... A Walk on the Tundra follows Inuujaq, a little girl who travels with her grandmother onto the tundra. There, Inuujaq learns that these tough little plants are much more important to Inuit than she originally believed. In addition to an informative storyline that teaches the importance of Arctic plants, this book includes a field guide with photographs and scientific information about a wide array of plants found throughout the ArcticA walk on the shoreline

south with his adoptive parents, Nukappia always looks forward to his summer visits with his birth family. After spending one night in town, Nukappia and his uncle Angu begin the long walk down the shore to the family summer campsite, where all of Nukappia's cousins and aunts and uncles are waiting for him. Along the way, Nukappia learns that the shoreline is not just ice and rocks and water. There is an entire ecosystem of plants and animals that call the shoreline home. From seaweed to clams to char to shore grasses, there is far more to see along the shoreline than Nukappia ever imaginedAnticosti: 450 millions d'années de vie

what we can do to get ready for it.Mention the word earthquake and most people think of California. But while the Golden State shakes on a regular basis, Washington State, Oregon, and British Columbia are located in a zone that can produce the world’s biggest earthquakes and tsunamis. In the eastern part of the continent, small cities and large, from Ottawa to Montréal to New York City, sit in active earthquake zones. In fact, more than 100-million North Americans live in active seismic zones, many of whom do not realize the risk to their community.Dispersals: On Plants, Borders, and Belonging

entangled in our human world to explore belonging, displacement, identity, and the truths of our shared futureA seed slips beyond a garden wall. A tree is planted on a precarious border. A shrub is stolen from its culture and its land. What happens when these plants leave their original homes and put down roots elsewhere?The themes in these fourteen essays become invigorating and intimate in Lee’s hands, centering on the lives of plants like seaweed, tangelos, and soy, and their entanglement with our human worlds. Lee explores the rich backstory of cherry trees in Berlin; a tea plant that grows in the Himalayan foothills just southwest of China; the world of algae and wakame, and the journeys they’ve made to reach us.Each of the plants considered in this collection are somehow perceived as being "out of place"—weeds, samples collected through imperial science, crops introduced and transformed by our hand. Lee looks at these plant species in their own context, even when we find them outside of it.Dispersals draws a gorgeous, sprawling map of the diaspora of flora. Combining memoir, history, and scientific research in poetic prose, Jessica J. Lee meditates on the question of how both plants and people come to belong, why both cross borders, and how our futures are more entwined than we might imagine.Space on Earth: How Thinking Like an Astronaut Can Help Save the Planet

500 tropical tree species, Trees of Panama and Costa Rica includes superb color photos, abundant color distribution maps, and concise descriptions of key characteristics, making this guide readily accessible to botanists, biologists, and casual nature lovers alike. The invaluable introductory chapters discuss tree diversity in Central America and the basics of tree identification. Family and species accounts are treated alphabetically and describe family size, number of genera and species, floral characteristics, and relative abundance. Color distribution maps supplement the useful species descriptions, and facing-page photographic plates detail bark, leaf, flower, or fruit of the species featured. Helpful appendices contain a full glossary, a comprehensive guide to leaf forms, and a list of families not covered. The only tree guide to cover both Panama and Costa Rica together Covers almost 500 species 438 high-resolution color photos 480 color distribution maps and two general maps Concise and jargon-free descriptions of key characteristics for every species Full glossary and guide to leaf forms includedConus of the Southeastern United States and Caribbean

significantly to marine biodiversity. The shells of these marine mollusks are prized for their amazing variety and extraordinary beauty. The neurotoxic venoms they produce—injected by a hollow, harpoon-like tooth into prey animals that are then paralyzed and swallowed whole—have a range of pharmaceutical applications, from painkillers to antidepressants. This beautifully illustrated book identifies 53 valid species of the southeastern United States and the Caribbean, a region that supports a diverse but taxonomically challenging group of Conus. Introductory chapters cover the evolution and phylogeny of the genus, and notes on methodology are provided. Detailed species accounts describe key identification features, taxonomy, distribution, ecology, toxicology, life history, and evolutionary relationships. The book includes more than 2,100 photos of shells on 109 splendid color plates; more than 100 additional photos, many depicting live animals in color; and 35 color distribution maps.Identifies 53 valid species—the first reassessment of western Atlantic Conus in more than seventy yearsFeatures more than 2,100 photos of shells on 109 color platesBlends the traditional shell-character approach to identification with cutting-edge shell and radular tooth morphometrics and molecular genetic analysesIncludes color images of live animals as well as color distribution mapsThe Last of Its Kind: The Search for the Great Auk and the Discovery of Extinction

and documented examples of extinction. A flightless bird that bred primarily on the remote islands of the North Atlantic, the last of its kind were killed in Iceland in 1844. Gísli Pálsson draws on firsthand accounts from the Icelanders who hunted the last great auks to bring to life a bygone age of Victorian scientific exploration while offering vital insights into the extinction of species.Pálsson vividly recounts how British ornithologists John Wolley and Alfred Newton set out for Iceland to collect specimens only to discover that the great auks were already gone. At the time, the Victorian world viewed extinction as an impossibility or trivialized it as a natural phenomenon. Pálsson chronicles how Wolley and Newton documented the fate of the last birds through interviews with the men who killed them, and how the naturalists&’ Icelandic journey opened their eyes to the disappearance of species as a subject of scientific concern—and as something that could be caused by humans.Blending a richly evocative narrative with rare, unpublished material as well as insights from ornithology, anthropology, and Pálsson&’s own North Atlantic travels, The Last of Its Kind reveals how the saga of the great auk opens a window onto the human causes of mass extinction.Petrels, Albatrosses, and Storm-Petrels of North America: A Photographic Guide

resource of its kind to appear in decades. This beautifully illustrated book describes how flowers use colors, shapes, and scents to advertise themselves; how they offer pollen and nectar as rewards; and how they share complex interactions with beetles, birds, bats, bees, and other creatures. The ecology of these interactions is covered in depth, including the timing and patterning of flowering, competition among flowering plants to attract certain visitors and deter others, and the many ways plants and animals can cheat each other. Pollination and Floral Ecology pays special attention to the prevalence of specialization and generalization in animal-flower interactions, and examines how a lack of distinction between casual visitors and true pollinators can produce misleading conclusions about flower evolution and animal-flower mutualism. This one-of-a-kind reference also gives insights into the vital pollination services that animals provide to crops and native flora, and sets these issues in the context of today's global pollination crisis. Provides the most up-to-date resource on pollination and floral ecology Describes flower advertising features and rewards, foraging and learning by flower-visiting animals, behaviors of generalist and specialist pollinators--and more Examines the ecology and evolution of animal-flower interactions, from the molecular to macroevolutionary scale Features hundreds of color and black-and-white illustrations
