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.

Biologist Rob Dunn's Every Little Thing is the story of man's obsessive quest to catalog life, from nanobacteria to new monkeys. In the tradition of E. O. Wilson, this engaging and fascinating work of popular science follows humanity's unending quest to discover every living thing in our natural world-from the unimaginably small in the most inhospitable of places on earth to the unimaginably far away in the unexplored canals on Mars.

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.

Cosmopolitan meets Scientific American in this entertaining and informative question-and-answer book on human attraction. Based on the latest studies in science, Do Gentlemen Really Prefer Blondes? answers more than 100 wild, weird, and very pressing questions.

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.

Zoologist Jo Wimpenny turns a critical eye to Aesop's fables to discover whether there is any scientific truth to their portrayal of the animal kingdom. She brings the tales into the twenty-first century, introducing the latest findings on the most fascinating branches of ethological research—the study of why animals do the things they do. In each chapter she interrogates a classic fable and a different topic—future planning, tool use, self-recognition, cooperation and deception—concluding with a verdict on the veracity of each fable's portrayal from a scientific perspective.

Human behavior is lopsided. When cradling a newborn child, most of us cradle the infant to the left. When posing for a portrait, we tend to put our left cheek forward. When kissing a lover, we tend to tilt our head to the right. Why is our behavior so lopsided and what does this teach us about our brains? How have humans always used this information to make our images more attractive and impactful? Can knowing how left-brain right-brain differences shape our opinions, tendencies, and attitudes help us make better choices in art, architecture, advertising, or even athletics?

"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?).

This book is perfect for anyone who eats and wants to understand what it takes to produce healthy food. Through new ideas and a different perspective, Marty shares a winning formula for success in modern family farming. Written by the owner of the Spence Farm featured in the documentary, Sustainable, this book provides listeners with the necessary steps an owner-operator must take to set up their family farm for long-term success.

Conventional wisdom about running is passed down like folklore (and sometimes contradicts itself). In Running Smart, Mariska van Sprundel, a science journalist and recreational runner who has had her fair share of injuries, sets out to explore the science behind such claims.

Physiology is the science of life, and sets out to understand how living things work and what makes them distinct from the non-living. It considers how our bodies are supplied with energy, how they maintain their internal parameters, the ways in which we gather and process information, the ways we take action, and the creation of new generations.

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.
