Deep Thinkers: Inside the Minds of Whales, Dolphins, and Porpoises
by Janet MannHumans aside, dolphins, whales, and porpoises are often considered to be the smartest creatures on Earth. Science and nature buffs are drawn to stories of their use of tools, their self-recognition, their beautiful and complex songs, and their intricate societies. But how do we know what we know, and what does it mean? In Deep Thinkers, renowned cetacean biologist Janet Mann gathers a gam of the world’s leading whale and dolphin researchers—including Luke Rendell, Hal Whitehead, and many more—to illuminate these vital questions, exploring the astounding capacities of cetacean brains. Diving into our current understanding of and dynamic research on dolphin and whale cognition, communication, and culture, Deep Thinkers reveals how incredibly sophisticated these mammals are—and how much we can learn about other animal minds by studying cetacean behavior. Through a combination of fascinating text and more than 150 beautiful and informative illustrations, chapters compare the intelligence markers of cetaceans with those of birds, bats, and primates, asking how we might properly define intelligence in nonhumans. As all-encompassing and profound as the seas in which these deep cetacean cultures have evolved, Deep Thinkers is an awesome and inspiring journey into the fathoms—a reminder of what we gain through their close study, and of what we lose when the great minds of the sea disappear.

Allowed to Grow Old: Portraits of Elderly Animals from Farm Sanctuaries
by Isa LeshkoThere’s nothing quite like a relationship with an aged pet—a dog or cat who has been at our side for years, forming an ineffable bond. Pampered pets, however, are a rarity among animals who have been domesticated. Farm animals, for example, are usually slaughtered before their first birthday. We never stop to think about it, but the typical images we see of cows, chickens, pigs, and the like are of young animals. What would we see if they were allowed to grow old? Isa Leshko shows us, brilliantly, with this collection of portraits. To create these portraits, she spent hours with her subjects, gaining their trust and putting them at ease. The resulting images reveal the unique personality of each animal. It’s impossible to look away from the animals in these images as they unforgettably meet our gaze, simultaneously calm and challenging. In these photographs we see the cumulative effects of the hardships of industrialized farm life, but also the healing that time can bring, and the dignity that can emerge when farm animals are allowed to age on their own terms. Each portrait is accompanied by a brief biographical note about its subject, and the book is rounded out with essays that explore the history of animal photography, the place of beauty in activist art, and much more. Open this book to any page. Meet Teresa, a thirteen-year-old Yorkshire Pig, or Melvin, an eleven-year-old Angora Goat, or Tom, a seven-year-old Broad Breasted White Turkey. You’ll never forget them.

Rainbow Dust: Three Centuries of Butterfly Delight
by Peter MarrenLike fluttering shards of stained glass, butterflies possess a unique power to pierce and stir the human soul. Indeed, the ancient Greeks explicitly equated the two in a single word, psyche, so that from early times butterflies were not only a form of life, but also an idea. Profound and deeply personal, written with both wisdom and wit, Peter Marren’s Rainbow Dust explores this idea of butterflies—the why behind the mysterious power of these insects we do not flee, but rather chase. At the age of five, Marren had his “Nabokov Moment,” catching his first butterfly and feeling the dust of its colored scales between his fingers. It was a moment that would launch a lifetime’s fascination rivaling that of the famed novelist—a fascination that put both in good company. From the butterfly collecting and rearing craze that consumed North America and Europe for more than two hundred years (a hobby that in some cases bordered on madness), to the potent allure of butterfly iconography in contemporary advertisements and their use in spearheading calls to conserve and restore habitats (even though butterflies are essentially economically worthless), Marren unveils the many ways in which butterflies inspire us as objects of beauty and as symbols both transient and transcendent. Floating around the globe and through the whole gamut of human thought, from art and literature to religion and science, Rainbow Dust is a cultural history rather than merely a natural one, a tribute to butterflies’ power to surprise, entertain, and obsess us. With a sway that far surpasses their fragile anatomy and gentle beat, butterfly wings draw us into the prismatic wonders of the natural world—and, in the words of Marren, these wonders take flight.

Dr. Eleanor's Book of Common Ants of California
by Eleanor Spicer Rice Alex Wild Rob DunnDid you know that for every human on earth, there are about one million ants? They are among the longest-lived insects—with some ant queens passing the thirty-year mark—as well as some of the strongest. Fans of both the city and countryside alike, ants decompose dead wood, turn over soil (in some places more than earthworms), and even help plant forests by distributing seeds. But while fewer than thirty of the nearly one thousand ant species living in North America are true pests, we cringe when we see them marching across our kitchen floors. No longer! In this witty, accessible, and beautifully illustrated guide, Eleanor Spicer Rice, Alex Wild, and Rob Dunn metamorphose creepy-crawly revulsion into myrmecological wonder. Emerging from Dunn’s ambitious citizen science project Your Wild Life (an initiative based at North Carolina State University) and the work of Brian Fisher with the California Academy of Sciences, Dr. Eleanor’s Book of Common Ants of California provides an eye-opening entomological overview of the natural history of California’s species most noted by project participants—and even offers tips on keeping ant farms in your home. Exploring species from the high noon and harvester ants to the honeypot and acrobat ants, and featuring Wild’s stunning photography, this guide will be a tremendous resource for teachers, students, and scientists alike. But more than this, it will transform the way Californians perceive the environment around them by deepening their understanding of its littlest inhabitants, inspiring everyone to find their inner naturalist, get outside, and crawl across the dirt—magnifying glass in hand.

Across the Bridge: Understanding the Origin of the Vertebrates
by Henry GeeOur understanding of vertebrate origins and the backbone of human history evolves with each new fossil find and DNA map. Many species have now had their genomes sequenced, and molecular techniques allow genetic inspection of even non-model organisms. But as longtime Nature editor Henry Gee argues in Across the Bridge, despite these giant strides and our deepening understanding of how vertebrates fit into the tree of life, the morphological chasm between vertebrates and invertebrates remains vast and enigmatic. As Gee shows, even as scientific advances have falsified a variety of theories linking these groups, the extant relatives of vertebrates are too few for effective genetic analysis. Moreover, the more we learn about the species that do remain—from sea-squirts to starfish—the clearer it becomes that they are too far evolved along their own courses to be of much use in reconstructing what the latest invertebrate ancestors of vertebrates looked like. Fossils present yet further problems of interpretation. Tracing both the fast-changing science that has helped illuminate the intricacies of vertebrate evolution as well as the limits of that science, Across the Bridge helps us to see how far the field has come in crossing the invertebrate-to-vertebrate divide—and how far we still have to go.

Zebra Stripes
by Tim CaroFrom eminent biologists like Alfred Russel Wallace and Charles Darwin to famous authors such as Rudyard Kipling in his Just So Stories, many people have asked, “Why do zebras have stripes?” There are many explanations, but until now hardly any have been seriously addressed or even tested. In Zebra Stripes, Tim Caro takes readers through a decade of painstaking fieldwork examining the significance of black-and-white striping and, after systematically dismissing every hypothesis for these markings with new data, he arrives at a surprising conclusion: zebra markings are nature’s defense against biting fly annoyance. Popular explanations for stripes range from camouflage to confusion of predators, social facilitation, and even temperature regulation. It is a serious challenge to test these proposals on large animals living in the wild, but using a combination of careful observations, simple field experiments, comparative information, and logic, Caro is able to weigh up the pros and cons of each idea. Eventually—driven by experiments showing that biting flies avoid landing on striped surfaces, observations that striping is most intense where biting flies are abundant, and knowledge of zebras’ susceptibility to biting flies and vulnerability to the diseases that flies carry—Caro concludes that black-and-white stripes are an adaptation to thwart biting fly attack. Not just a tale of one scientist’s quest to solve a classic mystery of biology, Zebra Stripes is also a testament to the tremendous value of longitudinal research in behavioral ecology, demonstrating how observation, experiment, and comparative research can together reshape our understanding of the natural world.

Dolphin Confidential: Confessions of a Field Biologist
by Maddalena BearziWho hasn’t fantasized about the unique thrill of working among charismatic and clever dolphins in the wild? Now we no longer have to rely solely on our imaginations . With Dolphin Confidential, Maddalena Bearzi invites all of us shore-bound dreamers to join her and travel alongside the dolphins. In this fascinating account, she takes us inside the world of a marine scientist and offers a firsthand understanding of marine mammal behavior, as well as the frustrations, delights, and creativity that make up dolphin research. In this intimate narrative, Bearzi recounts her experiences at sea, tracing her own evolution as a woman and a scientist from her earliest travails to her transformation into an advocate for conservation and dolphin protection. These compelling, in-depth descriptions of her fieldwork also present a captivating look into dolphin social behavior and intelligence. The central part of the book is devoted to the metropolitan bottlenose dolphins of California, as Bearzi draws on her extensive experience to offer insights into the daily lives of these creatures—as well as the difficulties involved in collecting the data that transforms hunches into hypotheses and eventually scientific facts. The book closes by addressing the critical environmental and conservation problems facing these magnificent, socially complex, highly intelligent, and emotional beings. An honest, down-to-earth analysis of what it means to be a marine biologist in the field today, Dolphin Confidential offers an entertaining, refreshingly candid, and always informative description of life among the dolphins.
Floating Gold: A Natural (and Unnatural) History of Ambergris
by Christopher Kemp“Preternaturally hardened whale dung” is not the first image that comes to mind when we think of perfume, otherwise a symbol of glamour and allure. But the key ingredient that makes the sophisticated scent linger on the skin is precisely this bizarre digestive by-product—ambergris. Despite being one of the world’s most expensive substances (its value is nearly that of gold and has at times in history been triple it), ambergris is also one of the world’s least known. But with this unusual and highly alluring book, Christopher Kemp promises to change that by uncovering the unique history of ambergris. A rare secretion produced only by sperm whales, which have a fondness for squid but an inability to digest their beaks, ambergris is expelled at sea and floats on ocean currents for years, slowly transforming, before it sometimes washes ashore looking like a nondescript waxy pebble. It can appear almost anywhere but is found so rarely, it might as well appear nowhere. Kemp’s journey begins with an encounter on a New Zealand beach with a giant lump of faux ambergris—determined after much excitement to nothing more exotic than lard—that inspires a comprehensive quest to seek out ambergris and its story. He takes us from the wild, rocky New Zealand coastline to Stewart Island, a remote, windswept island in the southern seas, to Boston and Cape Cod, and back again. Along the way, he tracks down the secretive collectors and traders who populate the clandestine modern-day ambergris trade. Floating Gold is an entertaining and lively history that covers not only these precious gray lumps and those who covet them, but presents a highly informative account of the natural history of whales, squid, ocean ecology, and even a history of the perfume industry. Kemp’s obsessive curiosity is infectious, and eager readers will feel as though they have stumbled upon a precious bounty of this intriguing substance.
Canine Confidential: Why Dogs Do What They Do
by Marc BekoffFor all the love and attention we give dogs, much of what they do remains mysterious. Just think about different behaviors you see at a dog park: We have a good understanding of what it means when dogs wag their tails—but what about when they sniff and roll on a stinky spot? Why do they play tug-of-war with one dog, while showing their bellies to another? Why are some dogs shy, while others are bold? What goes on in dogs’ heads and hearts—and how much can we know and understand? Canine Confidential has the answers. Written by award-winning scientist—and lifelong dog lover—Marc Bekoff, it not only brilliantly opens up the world of dog behavior, but also helps us understand how we can make our dogs’ lives the best they can possibly be. Rooted in the most up-to-date science on cognition and emotion—fields that have exploded in recent years—Canine Confidential is a wonderfully accessible treasure trove of new information and myth-busting. Peeing, we learn, isn’t always marking; grass-eating isn’t always an attempt to trigger vomiting; it’s okay to hug a dog—on their terms; and so much more. There’s still much we don’t know, but at the core of the book is the certainty that dogs do have deep emotional lives, and that as their companions we must try to make those lives as rich and fulfilling as possible. It’s also clear that we must look at dogs as unique individuals and refrain from talking about “the dog.” Bekoff also considers the practical importance of knowing details about dog behavior. He advocates strongly for positive training—there’s no need to dominate or shame dogs or to make them live in fear—and the detailed information contained in Canine Confidential has a good deal of significance for dog trainers and teachers. He also suggests that trainers should watch and study dogs in various contexts outside of those in which they are dealing with clients, canine and human, with specific needs. There’s nothing in the world as heartwarming as being greeted by your dog at the end of the workday. Read Canine Confidential, and you’ll be on the road to making your shared lives as happy, healthy, and rewarding as they can possibly be.
