"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 Category It 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.

A Bat Man in the Tropics
The euphoria of discovery is the only motivation many scientists need for studying nature and its secrets. Yet euphoria is rarely expressed in scientific publications. This book, a personal account of more than thirty years of fieldwork by one of the world’s leading bat biologists, wonderfully conveys the thrill of scientific discovery. Theodore Fleming’s work to document the lives and ecological importance of plant-visiting bats has taken him to the tropical forests of Panama, Costa Rica, and Australia, and to the lush Sonoran Desert of northwest Mexico and Arizona. This book tells the story of his fascinating career and recounts his many adventures in the field.<br /><br />Fleming weaves autobiographical reflections together with information on the natural history and ecology of bats and describes many other animals and plants he has encountered. His book details the stresses and rewards of life in scientific field camps, gives portraits of prominent biologists such as Dan Janzen and Peter Raven, and traces the development of modern tropical biology. A witness to the destruction and development of many of the forests he has visited throughout his career, Fleming makes a passionate plea for the conservation of these wild places.
Cane Toad Wars
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.<BR />  <BR /><I>Cane Toad Wars </I>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. 
Serendipity
"Many of the findings in the book . . . are classics of ecology. . . . A rare and delightful insight into timely science."—Jane Lubchenco, Nature "Estes's refreshing narrative deftly weaves rigorous science with personal reflection to create an absorbing and introspective read that is equal parts memoir, ecological textbook, and motivational guidebook for young ecologists."—Science 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’s 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. 
Evolution's Wedge
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.<br /><br />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.
