In 1540 Francisco Vasquez de Coronado introduced the first domestic livestock to the American Southwest. Over the subsequent four centuries, cattle, horses, and sheep have created a massive ecological experiment on these arid grasslands, changing them in ways we can never know with certainty. The Appleton-Whittell Research Ranch in the high desert of southeastern Arizona is an 8,000-acre sanctuary where grazing has been banned since 1968. In this spirited account of thirty years of research at the ranch, Carl and Jane Bock summarize the results of their fieldwork, which was aimed at understanding the dynamics of grasslands in the absence of livestock. The View from Bald Hill provides an intimate look at the natural history of this unique site and illuminates many issues pertaining to the protection and restoration of our nation's grasslands.

Treeshrews suffer from chronic mistaken identity: they are not shrews, and most are not found in trees. These squirrel-sized, brownish mammals with large, dark, lashless eyes were at one time thought to be primates. Even though most scientists now believe them to belong in their own mammalian order, Scandentia, they still are thought to resemble some of the earliest mammals, which lived alongside the dinosaurs. This book describes the results of the first comparative study of the ecology of treeshrews in the wild. Noted tropical mammalogist Louise H. Emmons conducted this pathbreaking study in the rainforests of Borneo as she tracked and observed six species of treeshrews. Emmons meticulously describes their habitat, diet, nesting habits, home range, activity patterns, social behavior, and many other facets of their lives. She also discusses a particularly interesting aspect of treeshrews: their enigmatic parental care system, which is unique among mammals.

American Bison combines the latest scientific information and one man's personal experience in an homage to one of the most magnificent animals to have roamed America's vast, vanished grasslands. Dale F. Lott, a distinguished behavioral ecologist who was born on the National Bison Range and has studied the buffalo for many years, relates what is known about this iconic animal's life in the wild and its troubled history with humans. Written with unusual grace and verve, "American Bison" takes us on a journey into the bison's past and shares a compelling vision for its future, offering along the way a valuable introduction to North American prairie ecology. We become Lott's companions in the field as he acquaints us with the social life and physiology of the bison, sharing stories about its impressive physical prowess and fascinating relationships. Describing the entire grassland community in which the bison live, he writes about the wolves, pronghorn, prairie dogs, grizzly bears, and other animals and plants, detailing the interdependent relationships among these inhabitants of a lost landscape.Lott also traces the long and dramatic relationship between the bison and Native Americans, and gives a surprising look at the history of the hide hunts that delivered the coup de grace to the already dwindling bison population in a few short years. This book gives us a peek at the rich and unique ways of life that evolved in the heart of America. Lott also dismantles many of the myths we have created about these ways of life, and about the bison in particular, to reveal the animal itself: ruminating, reproducing, and rutting in its full glory. His portrait of the bison ultimately becomes a plea to conserve its wildness and an eloquent meditation on the importance of the wild in our lives.

Twilight of the Mammoths
Ice Age Extinctions and the Rewilding of America
Häftad, Engelska, 2007

As recently as 11,000 years ago - 'near time' to geologists - mammoths, mastodons, gomphotheres, ground sloths, giant armadillos, native camels and horses, the dire wolf, and many other large mammals roamed North America. In what has become one of science's greatest riddles, these large animals vanished in North and South America around the time humans arrived at the end of the last great ice age. Part paleontological adventure and part memoir, "Twilight of the Mammoths" presents in detail internationally renowned paleoecologist Paul Martin's widely discussed and debated 'overkill' hypothesis to explain these mysterious megafauna extinctions. Taking us from Rampart Cave in the Grand Canyon, where he finds himself 'chest deep in sloth dung', to other important fossil sites in Arizona and Chile, Martin's engaging book, written for a wide audience, uncovers our rich evolutionary legacy and shows why he has come to believe that the earliest Americans literally hunted these animals to death.As he discusses the discoveries that brought him to this hypothesis, Martin relates many colorful stories and gives a rich overview of the field of paleontology as well as his own fascinating career. He explores the ramifications of the overkill hypothesis for similar extinctions worldwide and examines other explanations for the extinctions, including climate change. Martin's visionary thinking about our missing megafauna offers inspiration and a challenge for today's conservation efforts as he speculates on what we might do to remedy this situation - both in our thinking about what is 'natural' and in the natural world itself.

Part autobiography, part philosophical rumination, this evocative conservation odyssey explores the deep affinities between humans and our original habitat: grasslands. In a richly drawn, anecdotally driven narrative, Joe C. Truett, a grasslands ecologist who writes with a flair for language, traces the evolutionary, historical, and cultural forces that have reshaped North American rangelands over the past two centuries. He introduces an intriguing cast of characters - wildlife and grasslands biologists, archaeologists, ranchers, and petroleum geologists - to illuminate a wide range of related topics: our love affair with turf and how it manifests in lawns and sports, the ecological and economic dimensions of ranching, the glory of cowboy culture, grasslands and restoration ecology, and more. His book ultimately provides the background against which we can envision a new paradigm for restoring rangeland ecosystems-and a new paradigm for envisioning a more sustainable future.

Lizards in an Evolutionary Tree
Ecology and Adaptive Radiation of Anoles
Häftad, Engelska, 2011

Skickas inom 7-10 vardagar
Adaptive radiation, which results when a single ancestral species gives rise to many descendants, each adapted to a different part of the environment, is possibly the single most important source of biological diversity in the living world. One of the best-studied examples involves Caribbean Anolis lizards. With about 400 species, Anolis has played an important role in the development of ecological theory and has become a model system exemplifying the integration of ecological, evolutionary, and behavioral studies to understand evolutionary diversification. This major work, written by one of the best-known investigators of Anolis, reviews and synthesizes an immense literature. Jonathan B. Losos illustrates how different scientific approaches to the questions of adaptation and diversification can be integrated and examines evolutionary and ecological questions of interest to a broad range of biologists.

Evolution's Wedge
Competition and the Origins of Diversity
Inbunden, Engelska, 2012

Skickas inom 7-10 vardagar
Evolutionary biology has long sought to explain how new traits and new species arise. Darwin maintained that competition is key to understanding this biodiversity and held that selection acting to minimize competition causes competitors to become increasingly different, thereby promoting new traits and new species. Despite Darwin's emphasis, competition's role in diversification remains controversial and largely underappreciated. In their synthetic and provocative book, evolutionary ecologists David and Karin Pfennig explore competition's role in generating and maintaining biodiversity. The authors discuss how selection can lessen resource competition or costly reproductive interactions by promoting trait evolution through a process known as character displacement. They further describe character displacement's underlying genetic and developmental mechanisms. The authors then consider character displacement's myriad downstream effects, ranging from shaping ecological communities to promoting new traits and new species and even fueling large-scale evolutionary trends.Drawing on numerous studies from natural populations, and written for a broad audience, Evolution's Wedge seeks to inspire future research into character displacement's many implications for ecology and evolution.

To newly minted biologist James Estes, the sea otters he was studying in the leafy kelp forests off the coast of Alaska appeared to have an unbalanced relationship with their greater environment. Gorging themselves on the sea urchins that grazed among the kelp, these small charismatic mammals seemed to give little back in return. But as Estes dug deeper, he unearthed a far more complex relationship between the otter and its underwater environment, discovering that otters play a critical role in driving positive ecosystem dynamics. While teasing out the connective threads, he began to question our assumptions about ecological relationships. These questions would ultimately inspire a lifelong quest to better understand the surprising complexity of our natural world and the unexpected ways we discover it. Serendipity tells the story of James Estes' life as a naturalist and the concepts that have driven his interest in researching the ecological role of top-level predators.Using the relationships between sea otters, kelp, and sea urchins as a touchstone, Estes retraces his investigations of numerous other species, ecosystems, and ecological processes in an attempt to discover why ecologists can learn so many details about the systems in which they work and yet understand so little about the broader processes that influence these systems. Part memoir, part natural history, and deeply inquisitive, Serendipity will entertain and inform readers as it raises thoughtful questions about our relationship with the natural world.

In 1935, an Australian government agency imported 101 specimens of the Central and South American Cane Toad in an attempt to manage insects that were decimating sugar-cane harvests. In Australia the Cane Toad adapted and evolved with abandon, voraciously consuming native wildlife and killing predators with its lethal skin toxin. Today, hundreds of millions of Cane Toads have spread across the northern part of Australia and continue to move westward. The humble Cane Toad has become a national villain. Cane Toad Wars chronicles the work of intrepid scientist Rick Shine, who has been documenting the toad’s ecological impact in Australia and seeking to buffer it. Despite predictions of devastation in the wake of advancing toad hordes, the author’s research reveals a more complex and nuanced story. A firsthand account of a perplexing ecological problem and an important exploration of how we measure evolutionary change and ecological resilience, this book makes an effective case for the value of long-term natural history research in informing conservation practice.

"The author makes an eloquent plea for marine biodiversity conservation."—Library Journal"Harvell seems to channel the devotion that motivated the Blaschkas."—The Guardian Winner of the 2016 National Outdoor Book Award, Environment CategoryIt started with a glass octopus. Dusty, broken, and all but forgotten, it caught Drew Harvell’s eye. Fashioned in intricate detail by the father-son glassmaking team of Leopold and Rudolf Blaschka, the octopus belonged to a menagerie of unusual marine creatures that had been packed away for decades in a storage unit. More than 150 years earlier, the Blaschkas had been captivated by marine invertebrates and spun their likenesses into glass, documenting the life of oceans untouched by climate change and human impacts. Inspired by the Blaschkas’ uncanny replicas, Harvell set out in search of their living counterparts. In A Sea of Glass, she recounts this journey of a lifetime, taking readers along as she dives beneath the ocean's surface to a rarely seen world, revealing the surprising and unusual biology of some of the most ancient animals on the tree of life. On the way, we glimpse a century of change in our ocean ecosystems and learn which of the living matches for the Blaschkas’ creations are, indeed, as fragile as glass.Drew Harvell and the Blaschka menagerie are the subjects of the documentary Fragile Legacy, which won the Best Short Film award at the 2015 Blue Ocean Film Festival & Conservation Summit.
