Book Description
Why do baby sharks, hyenas, and pelicans kill their siblings? Why do beetles and mice commit infanticide? Why are twins and birth defects more common in older human mothers? A Natural History of Families concisely examines what behavioral ecologists have discovered about family dynamics and what these insights might tell us about human biology and behavior. Scott Forbes's engaging account describes an uneasy union among family members in which rivalry for resources often has dramatic and even fatal consequences. In nature, parents invest resources and control the allocation of resources among their offspring to perpetuate their genetic lineage. Those families sometimes function as cooperative units, the nepotistic and loving havens we choose to identify with. In the natural world, however, dysfunctional familial behavior is disarmingly commonplace. While explaining why infanticide, fratricide, and other seemingly antisocial behaviors are necessary, Forbes also uncovers several surprising applications to humans. Here the conflict begins in the moments following conception as embryos struggle to wrest control of pregnancy from the mother, and to wring more nourishment from her than she can spare, thus triggering morning sickness, diabetes, and high blood pressure. Mothers, in return, often spontaneously abort embryos with severe genetic defects, allowing for prenatal quality control of offspring. Using a broad sweep of entertaining examples culled from the world of animals and humans, A Natural History of Families is a lively introduction to the behavioral ecology of the family.

Book Description
According to American Demographics magazine, by the year 2010 the number of married couples without children is expected to increase by nearly 50%, to nearly 31 million. The non-profit organization, Childless By Choice, reports that one in seven married couples in the United States is consciously deciding not to have children. For more married couples than ever before, their life plan together does not include raising a family. Yet, as these numbers grow, in many ways society continues to frown on the choice not to have children. Although more couples are making this decision, they often feel misunderstood, and face societal misperceptions about themselves, their marriage, and their choice not to have children. Through candid interviews and photographs, Families of Two: Interviews with Happily Married Couples Without Children by Choice takes us into the lives of happily married couples without children by choice. It dispels the myths often associated with this choice, helps couples who are deciding whether to have children, and offers insight to friends and family of couples who have chosen or may choose not to have children. Families of Two expands our ways of understanding marriage in today’s society, and gives examples of roadmaps for marriage without children. Families of Two celebrates the many people who are living lives that do not include parenthood, and the many ways to live happily ever after.

Book Description
Advance praise for Flies Stephen A. Marshall has delivered one of the most beautiful and useful accounts of insect life ever written. -- Edward O. Wilson, Research Professor Emeritus, Harvard University Meticulously researched and illustrated with more than 2000 color photographs taken by the author, Flies is a landmark reference book that will be indispensable to any naturalist, biologist or entomologist. Most photographs in this encyclopedic reference were taken in the field and show the insects in their natural environment. All of the world's fly families are included, with photographic coverage spanning the range from common deer flies and fruit flies through to deadly tsetse flies and malaria mosquitoes, with thousands of spectacular species such as exotic stalk eyed flies, giant robber flies and hedgehog flies in between. Flies is broken up into three parts: Life Histories, Habits and Habitats of Flies; Diversity; and Identifying and Studying Flies. The 20 pages of profusely illustrated keys linked to the unprecedented photographic coverage of the world's fly families and subfamilies enable the reader to identify most flies quickly and accurately, and to readily access information about each family as well as hundreds of distinctive genera and species. Flies includes: Part 1: Life Histories, Habits and Habitats of Flies Chapter 1 -- Life Histories of Flies Chapter 2 -- Flies, Plants and Fungi Chapter 3 -- Flies and Vertebrates Chapter 4 -- Flies and Invertebrates Part 2: Diversity Chapter 5 -- Origins and Distribution of the Diptera Chapter 6 -- The Lower Diptera Chapter 7 -- The Lower Brachycera and Empidoidea Chapter 8 -- The Higher Brachycera or Cyclorrhapha Part 3: Identifying and Studying Flies Chapter 9 -- Collecting, Preserving and Rearing Flies Chapter 10 -- Identifying Fly Families

Book Description
Plant Families is an easy-to-use, beautifully illustrated guide to the more than seventy core plant families every horticulturist, gardener, or budding botanist needs to know. It introduces the basics of plant genealogy and teaches readers how to identify and understand the different structures of flowers, trees, herbs, shrubs, and bulbs. It then walks through each family, explaining its origins and range and describing characteristics such as size, flowers, and seeds. Each family is accompanied by full-color botanical illustrations and diagrams. "Uses For" boxes planted throughout the book provide practical gardening tips related to each family. By understanding how botanists create these groupings, we can become more apt at spotting the unique characteristics of a plant and identifying it faster and more accurately. Understanding plant families also helps us to make sense of- and better appreciate- the enormous biological diversity of the plant kingdom.

Book Description
Family isn't just important. It's everything. From lions hunting as a pride to penguins huddling together to keep from freezing in the bitter Antarctic winter, many animals are dependent on complex social relationships for their survival. Powerful dynasties lay claim to vast swathes of territory, fighting off rivals and securing their hunting grounds for generations to come. Dynasties offers an immersive insight into the shifting hierarchies of animal families. Each chapter follows a different dynasty, from the Marsh Lions of the Masai Mara to rival packs of painted wolves, from a tiger protecting her newborn cubs to a chimpanzee troop and the penguin colonies of the Antarctic. Alongside tender moments when bonds are strengthened through grooming and play, the book charts the rivalries that tip the balance of power, when family members turn against each other and younger animals grow strong enough to challenge for control. With over 200 stunning photographs and insights from the crew of the BBC series, Dynasties reveals in astonishing detail the intricate social lives of our planet’s most fascinating animals.

Book Description
Inspired by a debate between Noam Chomsky and Jean Piaget, this work traces the development of natural history from Aristotle to Darwin, and demonstrates how the science of plants and animals has emerged from the common conceptions of folkbiology.
