Lake Okoboji in northwest Iowa is the jewel of the Iowa Great Lakes. A region of wetlands formed by prairie potholes, the area is rich with lakes, sloughs, fens, creeks, prairies, and kettleholes. In this readable and beautifully illustrated volume, Michael Lannoo presents an extensive natural history of Okoboji and its cherished wetlands that examines that world of our grandparents, compares it to today's world, and extrapolates to the world of our grandchildren.
Reproduction is among the most basic of human biological functions, both for our distant ancestors and for ourselves, whether we live on the plains of Africa or in North American suburbs. Our reproductive biology unites us as a species, but it has also been an important engine of our evolution. In the way our bodies function today we can see both the imprint of our formative past and implications for our future. It is the infinitely subtle and endlessly dramatic story of human reproduction and its evolutionary context that Peter T. Ellison tells in On Fertile Ground.
Ranging from the latest achievements of modern fertility clinics to the lives of subsistence farmers in the rain forests of Africa, this book offers both a remarkably broad and a minutely detailed exploration of human reproduction. Ellison, a leading pioneer in the field, combines the perspectives of anthropology, stressing the range and variation of human experience; ecology, sensitive to the two-way interactions between humans and their environments; and evolutionary biology, emphasizing a functional understanding of human reproductive biology and its role in our evolutionary history.
Whether contrasting female athletes missing their periods and male athletes using anabolic steroids with Polish farm women and hunter-gatherers in Paraguay, or exploring the intricate choreography of an implanting embryo or of a nursing mother and her child, On Fertile Ground advances a rich and deeply satisfying explanation of the mechanisms by which we reproduce and the evolutionary forces behind their design.
The story of seeds, in a nutshell, is a tale of evolution. From the tiny sesame that we sprinkle on our bagels to the forty-five-pound double coconut borne by the coco de mer tree, seeds are a perpetual reminder of the complexity and diversity of life on earth. With An Orchard Invisible, Jonathan Silvertown presents the oft-ignored seed with the natural history it deserves, one nearly as varied and surprising as the earth’s flora itself.
Beginning with the evolution of the first seed plant from fernlike ancestors more than 360 million years ago, Silvertown carries his tale through epochs and around the globe. In a clear and engaging style, he delves into the science of seeds: How and why do some lie dormant for years on end? How did seeds evolve? The wide variety of uses that humans have developed for seeds of all sorts also receives a fascinating look, studded with examples, including foods, oils, perfumes, and pharmaceuticals. An able guide with an eye for the unusual, Silvertown is happy to take readers on unexpected—but always interesting—tangents, from Lyme disease to human color vision to the Salem witch trials. But he never lets us forget that the driving force behind the story of seeds—its theme, even—is evolution, with its irrepressible habit of stumbling upon new solutions to the challenges of life.
"I have great faith in a seed," Thoreau wrote. "Convince me that you have a seed there, and I am prepared to expect wonders." Written with a scientist’s knowledge and a gardener’s delight, An Orchard Invisible offers those wonders in a package that will be irresistible to science buffs and green thumbs alike.
This lively examination of the structure, classification, evolution, and ecology of the Orchidaceae will appeal to anyone with an eye for beauty or a bent for natural history. It will provide professional biologists and amateur orchidists alike with a deeper understanding--and a thoroughly new classification--of this, the largest flowering family in the plant kingdom.
The book is richly illustrated, with 95 color photographs and 99 line drawings emphasizing orchid morphology. But in the context of serious orchidology, aesthetic richness is not a superficial vanity. It is the result of evolutionary processes that demand adaptation and reward diversity, and Dressler's exploration of these mechanisms demonstrates how well the orchids have met the challenge, with over 20,000 species, a geographical range from Sweden to Tierra del Fuego, and, at times, as many as 47 different species on a single tree. But both the orchids' success and their profligate beauty are grounded, in part, in their voluptuary nature, and one of Dressler's most engaging themes is the reproductive adaptations, worthy of a Renaissance courtesan, that orchids use to attract, deceive, and manipulate pollinating insects.
The orchid family is actively evolving, providing rich possibilities for comparative study. Yet no one, whether professional or amateur, could reasonably proceed without first addressing Robert Dressler's The Orchids. Its new classification alone, including pollination biology, phyletic trends, chromosome counts, and generic relationships, will stand as a watershed contribution to the field.
How did the dog become man’s best friend? A celebrated anthropologist unearths the mysterious origins of the unique partnership that rewrote the history of both species.
Dogs and humans have been inseparable for more than 40,000 years. The relationship has proved to be a pivotal development in our evolutionary history. The same is also true for our canine friends; our connection with them has had much to do with their essential nature and survival. How and why did humans and dogs find their futures together, and how have these close companions (literally) shaped each other? Award-winning anthropologist Pat Shipman finds answers in prehistory and the present day.
In Our Oldest Companions, Shipman untangles the genetic and archaeological evidence of the first dogs. She follows the trail of the wolf-dog, neither prehistoric wolf nor modern dog, whose bones offer tantalizing clues about the earliest stages of domestication. She considers the enigma of the dingo, not quite domesticated yet not entirely wild, who has lived intimately with humans for thousands of years while actively resisting control or training. Shipman tells how scientists are shedding new light on the origins of the unique relationship between our two species, revealing how deep bonds formed between humans and canines as our guardians, playmates, shepherds, and hunters.
Along the journey together, dogs have changed physically, behaviorally, and emotionally, as humans too have been transformed. Dogs’ labor dramatically expanded the range of human capability, altering our diets and habitats and contributing to our very survival. Shipman proves that we cannot understand our own history as a species without recognizing the central role that dogs have played in it.
