On a clear May afternoon at the end of his junior year at Harvard, Howard Axelrod played a pick-up game of basketball. In a skirmish for a loose ball, a boy's finger hooked behind Axelrod's eyeball and left him permanently blinded in his right eye. A week later, he returned to the same dorm room, but to a different world. A world where nothing looked solid, where the distance between how people saw him and how he saw had widened into a gulf.

In Unnatural Companions, journalist Peter Christie issues a call to action for pet owners. If we hope to reverse the alarming trend of wildlife decline, pet owners must acknowledge the pets-versus-conservation dilemma and concede that our well-fed and sheltered cats too often prey on small backyard wildlife and seemingly harmless reptiles released into the wild might be the next destructive invasive species. We want our pets to eat nutritionally healthy food, but how does the designer food we feed them impact the environment?

As humans accelerate global warming while laying waste to the environment, animals and plants must flee to the margins: on scattered nature reserves, between major highways, or among urban sprawl. And when even these places become too hot and inhospitable, wildlife is left with only one path to survival: an often-formidable journey toward the poles as they race to find a new home in a warming world. Award-winning environmental journalist Benjamin von Brackel traces these awe-inspiring journeys and celebrates the remarkable resilience of species around the world.

Life histories can be defined as the means by which individuals (or more precisely genotypes) vary their age- or stage-specific expenditures of reproductive effort in response to genetic, phenotypic, and environmental correlates of survival and fecundity. Life histories reflect the expression of traits most closely related to individual fitness, such as age and size at maturity, number and size of offspring, and the timing of the expression of those traits throughout an individual's life. Life-history research plays an integral role in species conservation and management.

In 1995, the National Trust for Scotland acquired Mar Lodge Estate in the heart of the Cairngorms. Home to over 5,000 species, this vast expanse of Caledonian woodlands, subarctic mountains, bogs, moors, roaring burns, and frozen lochs could be a place where environmental conservation and Highland field sports would exist in harmony. The only problem was that due to centuries of abuse by human hands, the ancient Caledonian pinewoods were dying, and it would take radical measures to save them.

In this collection of natural-history essays, biologist Joan Maloof embarks on a series of lively, fact-filled expeditions into forests of the eastern United States. Through Maloof's engaging, conversational style, each essay offers a lesson in stewardship as it explores the interwoven connections between a tree species and the animals and insects whose lives depend on it - and who, in turn, work to ensure the tree's survival.

In The Soul of All Living Creatures, Virga draws from his decades in veterinary practice to reveal how we can enrich our own appreciation of life, enhance our character, nurture our relationships, and deepen our grasp of spirituality. Virga discerningly illuminates basic traits shared by both humans and animals and makes animal behavior meaningful, relevant, and easy to understand.

In October 2012, a replica of the famous HMS Bounty, an eighteenth-century tall sailing ship, was on a collision course with a storm that would become the largest hurricane ever recorded in the Atlantic - a clash that would prove dramatic, tragic, perplexing, and ultimately one of the most unforgettable stories of Superstorm Sandy. Crewed by an eclectic team of seafarers, the Bounty was led by Robin Walbridge, their highly respected captain with decades at the helm, whose actions - sometimes questionable - decided the fate of his ship and crew.

In Frankenstein's Cat, journalist Emily Anthes takes us from petri dish to pet store as she explores how biotechnology is shaping the future of our furry and feathered friends. Through her encounters with scientists, conservationists, ethicists, and entrepreneurs, Anthes reveals that while some of our interventions may be trivial (behold: the GloFish), others could improve the lives of many species - including our own. So what does biotechnology really mean for the world's wild things? And what do our brave new beasts tell us about ourselves?

On June 23, 2000, the iron-ore carrier MV Treasure, en route from Brazil to China, foundered off the coast of Cape Town, South Africa, spilling 1,300 tons of oil into the ocean and contaminating the habitat of 75,000 penguins. Realizing that 41 percent of the world's population of African penguins could perish, local conservation officials immediately launched a massive rescue operation.

Forget the Kama Sutra. When it comes to inventive sex acts, just look to the sea. There we find the elaborate mating rituals of armored lobsters; giant right whales engaging in a lively threesome while holding their breath; full-moon sex parties of groupers; and daily mating blitzes by blueheaded wrasse. Deep-sea squid perform inverted 69s while hermaphrodite sea slugs link up in giant sex loops.

With predictions of a human population of more than nine billion by the middle of this century and 11 billion by 2100, we stand at a crossroads in our agricultural evolution. In this clear and engaging book, wildlife biologist John M. Marzluff takes a personal approach to sustainable agriculture. He travels to farms and ranches across North and Central America, including a Nebraska corn and soybean farm, California vineyards, cattle ranches in Montana, and small sustainable farms in Costa Rica, to understand the unique challenges and solutions to sustainable food production.

Now in audio - a fascinating work of popular science from a world-renowned expert on mosquitoes and a prize-winning reporter. In this lively and comprehensive portrait of the mosquito, its role in history, and its threat to mankind, Spielman and D'Antonio take a mosquito's-eye view of nature and man. They show us how mosquitoes breed, live, mate, and die and introduce us to their enemies, both natural and man-made.

In this Very Short Introduction, Paul B. Wignall looks at the causes and nature of extinctions, past and present, and the factors that can make a species vulnerable. Summarizing what we know about all of the major and minor extinction events, he examines some of the greatest debates in modern science, such as the relative role of climate and humans in the death of the Pleistocene megafauna, including mammoths and giant ground sloths, and the roles that global warming, ocean acidification, and deforestation are playing in present-day extinctions.

America was built on white pine. From the 1600s through the Civil War and beyond, it was used to build the nation's ships and houses, barns, and bridges. Yet this popularity came at a cost: by the end of the nineteenth century, clear cutting had decimated much of America's white pine forests. In White Pine, ecologist and writer John Pastor takes listeners on walk through history, connecting the white pine forests that remain today to a legacy of destruction and renewal.

"Lively writing about science and nature depends less on the offering of good answers, I think, than on the offering of good questions," said David Quammen in the original introduction to Natural Acts. For more than two decades, he has stuck to that credo. In this updated version of Natural Acts, curiosity leads him from New Mexico to Romania, from the Congo to the Amazon, asking questions about mosquitoes (what are their redeeming merits?), dinosaurs (how did they change the life of a dyslexic Vietnam vet?), and cloning (can it save endangered species?).

Science Be Dammed is an alarming reminder of the high stakes in the management - and perils in the mismanagement - of water in the Western United States. It seems deceptively simple: Even when clear evidence was available that the Colorado River could not sustain ambitious dreaming and planning by decision-makers throughout the 20th century, river planners and political operatives irresponsibly made the least sustainable and most dangerous long-term decisions.

In this meditation on the music of the natural world, Moore celebrates the call of loons, howl of wolves, bellow of whales, laughter of children, and shriek of frogs, even as she warns of the threats against them. Each group of essays moves, as Moore herself has been moved, from celebration to lamentation to bewilderment and finally to the determination to act in defense of wild songs and the creatures who sing them.

Do animals have moral rights? If so, what does this mean? What sorts of mental lives do animals have, and how should we understand welfare? By presenting models for understanding animals' moral status and rights, and examining their mental lives and welfare, David DeGrazia explores the implications for how we should treat animals in connection with our diet, zoos, and research. Animal Rights distinguishes itself by combining intellectual rigor with accessibility, offering a distinct moral voice with a non-polemical tone.

In The Gospel of Kindness, Janet M. Davis explores the broad cultural and social influence of the American animal welfare movement at home and overseas from the Second Great Awakening to the Second World War. Dedicated primarily to laboring animals at its inception in an animal-powered world, the movement eventually included virtually all areas of human and animal interaction.
