Living at the limits of our ordinary perception, mosses are a common but largely unnoticed element of the natural world. Gathering Moss is a beautifully written mix of science and personal reflection that invites readers to explore and learn from the elegantly simple lives of mosses.

In this series of linked personal essays, Robin Wall Kimmerer leads general readers and scientists alike to an understanding of how mosses live and how their lives are intertwined with the lives of countless other beings. Kimmerer explains the biology of mosses clearly and artfully, while at the same time reflecting on what these fascinating organisms have to teach us.

Drawing on her diverse experiences as a scientist, mother, teacher, and writer of Native American heritage, Kimmerer explains the stories of mosses in scientific terms as well as in the framework of indigenous ways of knowing. In her book, the natural history and cultural relationships of mosses become a powerful metaphor for ways of living in the world.

"Gene sharing" means that the different functions of a protein may share the same gene--that is, a protein produced by a gene evolved to fulfill a specialized function for one biological role may also perform alternate functions for other biological roles.

In the 1980s and early 1990s, Joram Piatigorsky and colleagues coined the term "gene sharing" to describe the use of multifunctional proteins as crystallins in the eye lens. In Gene Sharing and Evolution Piatigorsky explores the generality and implications of gene sharing throughout evolution and argues that most if not all proteins perform a variety of functions in the same and in different species, and that this is a fundamental necessity for evolution.

How is a gene identified, by its structure or its function? Do the boundaries of a gene include its regulatory elements? What is the influence of gene expression on natural selection of protein functions, and how is variation in gene expression selected in evolution? These are neither new nor resolved questions. Piatigorsky shows us that the extensiveness of gene sharing and protein multifunctionality offers a way of responding to these questions that sheds light on the complex interrelationships among genes, proteins, and evolution.

Aristotle, great Greek philosopher, researcher, reasoner, and writer, born at Stagirus in 384 BC, was the son of a physician. He studied under Plato at Athens and taught there (367–347); subsequently he spent three years at the court of a former pupil in Asia Minor. After some time at Mitylene, in 343–342 he was appointed by King Philip of Macedon to be tutor of his teen-aged son Alexander. After Philip’s death in 336, Aristotle became head of his own school (of “Peripatetics”), the Lyceum at Athens. Because of anti-Macedonian feeling there after Alexander’s death in 323, he withdrew to Chalcis in Euboea, where he died in 322.

Nearly all the works Aristotle prepared for publication are lost; the priceless ones extant are lecture-materials, notes, and memoranda (some are spurious). They can be categorized as follows:

I Practical: Nicomachean Ethics; Great Ethics (Magna Moralia); Eudemian Ethics; Politics; Economics (on the good of the family); On Virtues and Vices.
II Logical: Categories; Analytics (Prior and Posterior); Interpretation; Refutations used by Sophists; Topica.
III Physical: Twenty-six works (some suspect) including astronomy, generation and destruction, the senses, memory, sleep, dreams, life, facts about animals, etc.
IV Metaphysics: on being as being.
V Art: Rhetoric and Poetics.
VI Other works including the Constitution of Athens; more works also of doubtful authorship.
VII Fragments of various works such as dialogues on philosophy and literature; and of treatises on rhetoric, politics, and metaphysics.

The Loeb Classical Library edition of Aristotle is in twenty-three volumes.

In recent decades immunology has been one of the most exciting--and successful--fields of biomedical research. Over the past thirty years immunologists have acquired a detailed understanding of the immune system's unique recognition mechanism and of the cellular and chemical means used to destroy or neutralize invading organisms. This understanding has been formulated in terms of the clonal selection theory, the dominant explanation of immune behavior. That story is the subject of The Generation of Diversity.

A major problem for immunologists had long been to determine how cells of the immune system could produce millions of distinct antibodies--and produce them on demand. The clonal selection theory explains that cells with genetic instructions to produce each antibody exist in the body in small numbers until exposure to the right molecule--the antigen--triggers the selective cloning that will reproduce exactly the cell needed. But how can so many different antibody-producing cells be generated from such limited genetic material? The solution to this question came from new applications of molecular biology, and, as the authors argue, the impact of the new techniques changed both the methods and the concepts of immunology.

The Generation of Diversity is an intellectual history of the major theoretical problem in immunology and its resolution in the post-World War II period. It will provide for immunologists essential background for understanding the conceptual conflicts occurring in the field today.

Can genes determine which fifty-year-old will succumb to Alzheimer’s, which citizen will turn out on voting day, and which child will be marked for a life of crime? Yes, according to the Internet, a few scientific studies, and some in the biotechnology industry who should know better. Sheldon Krimsky and Jeremy Gruber gather a team of genetic experts to argue that treating genes as the holy grail of our physical being is a patently unscientific endeavor. Genetic Explanations urges us to replace our faith in genetic determinism with scientific knowledge about how DNA actually contributes to human development.

The concept of the gene has been steadily revised since Watson and Crick discovered the structure of the DNA molecule in 1953. No longer viewed by scientists as the cell’s fixed set of master molecules, genes and DNA are seen as a dynamic script that is ad-libbed at each stage of development. Rather than an autonomous predictor of disease, the DNA we inherit interacts continuously with the environment and functions differently as we age. What our parents hand down to us is just the beginning. Emphasizing relatively new understandings of genetic plasticity and epigenetic inheritance, the authors put into a broad developmental context the role genes are known to play in disease, behavior, evolution, and cognition.

Rather than dismissing genetic reductionism out of hand, Krimsky and Gruber ask why it persists despite opposing scientific evidence, how it influences attitudes about human behavior, and how it figures in the politics of research funding.

They mastermind our lives, shaping our features, our health, and our behavior, even in the sacrosanct realms of love and sex, religion, aging, and death. Yet we are the ones who house, perpetuate, and give the promise of immortality to these biological agents, our genetic gods. The link between genes and gods is hardly arbitrary, as the distinguished evolutionary geneticist John Avise reveals in this compelling book. In clear, straightforward terms, Avise reviews recent discoveries in molecular biology, evolutionary genetics, and human genetic engineering, and discusses the relevance of these findings to issues of ultimate concern traditionally reserved for mythology, theology, and religious faith.

The book explains how the genetic gods figure in our development--not just our metabolism and physiology, but even our emotional disposition, personality, ethical leanings, and, indeed, religiosity. Yet genes are physical rather than metaphysical entities. Having arisen via an amoral evolutionary process--natural selection--genes have no consciousness, no sentient code of conduct, no reflective concern about the consequences of their actions. It is Avise's contention that current genetic knowledge can inform our attempts to answer typically religious questions--about origins, fate, and meaning. The Genetic Gods challenges us to make the necessary connection between what we know, what we believe, and what we embody.

In this comprehensive account of olfactory communication and territorial behavior in the Mongolian gerbil, Del Thiessen and PaulineYahr provide the first detailed study of the neurological and physiological mechanisms that control these basic functions. In addition to explaining the links between hormones, genes, olfactory cues, and territorial acts, they also offer a more general picture of gerbil behavior, as well as a brief look at other mammalian species that communicate social status by way of olfactory messages.

Territorial behavior, as defined by the authors, includes all acts that are restricted to a particular area and are crucial for successful reproduction. In the Mongolian gerbil, and probably in other mammals as well, territoriality is controlled by sex hormones acting on specific areas of the central nervous system. Hormones from the gonads apparently act in the brain by altering the genetic apparatus controlling biochemicals used in neural communication. Without these hormones, the animal is socially inert and unable to transmit genes to the next generation. The authors conclude from the results of over ten years of investigation that the most complex social interactions depend on the integrity of the hormone system and its constant tuning by olfactory stimuli.

The book incorporates a review of all previously known studies of gerbil behavior and representative data for many other scent-marking species. A stereotaxic brain atlas for the gerbil is a feature that will be especially helpful to other researchers. The book's eclectic nature should make it valuable to anyone concerned with territorial behavior, hormones and behavior, or brain processes, as well as to those who are specifically interested in the Mongolian gerbil.

Upon its publication in 1957 A Glossary of Mycology was acclaimed by scientific and medical journals throughout the United States and Britain. The International Record of Medicine called it "a valuable reference book for every mycologist." Antibiotics and Chemotherapy recommended it as essential for all scientific libraries. The Bryologist said, "The authors are to be congratulated upon the wealth of information . . . the book is highly recommended in every respect."

Nearly 7000 terms--technical terms and their derivations; common or popular, vernacular, and obsolete terms; terms used in the field of medical mycology and antibiotics; names of the originators of terms; folklore terms; and color terms--were covered by the original edition. Also included were terms which, though not strictly mycological, occur frequently in literature of particular interest to mycologists.

This revision brings the work up to date with the considerable developments in the field since its first publication. Nearly 350 terms have been added, and new definitions for many of the original terms supplied. Excellent diagrammatic line drawings by Henry A. C. Jackson illustrate 191 of the terms.

In this spirited and irreverent critique of Darwin’s long hold over our imagination, a distinguished philosopher of science makes the case that, in culture as well as nature, not only the fittest survive: the world is full of the “good enough” that persist too.

Why is the genome of a salamander forty times larger than that of a human? Why does the avocado tree produce a million flowers and only a hundred fruits? Why, in short, is there so much waste in nature? In this lively and wide-ranging meditation on the curious accidents and unexpected detours on the path of life, Daniel Milo argues that we ask these questions because we’ve embraced a faulty conception of how evolution—and human society—really works.

Good Enough offers a vigorous critique of the quasi-monopoly that Darwin’s concept of natural selection has on our idea of the natural world. Darwinism excels in accounting for the evolution of traits, but it does not explain their excess in size and number. Many traits far exceed the optimal configuration to do the job, and yet the maintenance of this extra baggage does not prevent species from thriving for millions of years. Milo aims to give the messy side of nature its due—to stand up for the wasteful and inefficient organisms that nevertheless survive and multiply.

But he does not stop at the border between evolutionary theory and its social consequences. He argues provocatively that the theory of evolution through natural selection has acquired the trappings of an ethical system. Optimization, competitiveness, and innovation have become the watchwords of Western societies, yet their role in human lives—as in the rest of nature—is dangerously overrated. Imperfection is not just good enough: it may at times be essential to survival.

To observe a dog's guilty look.

to witness a gorilla's self-sacrifice for a wounded mate, to watch an elephant herd's communal effort on behalf of a stranded calf--to catch animals in certain acts is to wonder what moves them. Might there he a code of ethics in the animal kingdom? Must an animal be human to he humane? In this provocative book, a renowned scientist takes on those who have declared ethics uniquely human Making a compelling case for a morality grounded in biology, he shows how ethical behavior is as much a matter of evolution as any other trait, in humans and animals alike.

World famous for his brilliant descriptions of Machiavellian power plays among chimpanzees-the nastier side of animal life--Frans de Waal here contends that animals have a nice side as well. Making his case through vivid anecdotes drawn from his work with apes and monkeys and holstered by the intriguing, voluminous data from his and others' ongoing research, de Waal shows us that many of the building blocks of morality are natural: they can he observed in other animals. Through his eyes, we see how not just primates but all kinds of animals, from marine mammals to dogs, respond to social rules, help each other, share food, resolve conflict to mutual satisfaction, even develop a crude sense of justice and fairness.

Natural selection may be harsh, but it has produced highly successful species that survive through cooperation and mutual assistance. De Waal identifies this paradox as the key to an evolutionary account of morality, and demonstrates that human morality could never have developed without the foundation of fellow feeling our species shares with other animals. As his work makes clear, a morality grounded in biology leads to an entirely different conception of what it means to he human--and humane.

From simple reflexes to complex choreographies of movement, all animal behavior is governed by a nervous system. But what kind of government is it—a dictatorship or a democracy?

Nervous systems consist of circuits of interconnected nerve cells (neurons) that transmit and receive information via electrical signals. Every moment, each neuron adds up stimulating and inhibiting inputs from many other neurons to determine whether to send an electrical signal to its recipients. Some circuits are dominated by a single “dictator” neuron that gathers information from many sources and then issues commands, such as the Mauthner neuron that triggers escape in fish. In other more “democratic” circuits, such as those mediating eye movements in monkeys, the outcome is determined by a tally of “votes” from a large population of neurons. Rhythmic movements like breathing and locomotion are generated by “government programs” within the central nervous system, but modified by a soup of chemicals and by free market–like feedback from sensory neurons. Nervous systems also use sophisticated surveillance of the surrounding environment and keep track of their own decisions in order to avoid internal conflicts. Nervous systems are not restricted to using one set of procedures at a time. They have evolved over long periods to control behaviors in whichever ways are most effective, and they essentially combine multiple forms of government simultaneously.

Engaging and accessible, Governing Behavior explains the variety of structures and strategies that control behavior, while providing an overview of thought-provoking debates and cutting-edge research in neurobiology.

What a big brain we have for all the small talk we make. It's an evolutionary riddle that at long last makes sense in this intriguing book about what gossip has done for our talkative species. Psychologist Robin Dunbar looks at gossip as an instrument of social order and cohesion--much like the endless grooming with which our primate cousins tend to their social relationships.

Apes and monkeys, humanity's closest kin, differ from other animals in the intensity of these relationships. All their grooming is not so much about hygiene as it is about cementing bonds, making friends, and influencing fellow primates. But for early humans, grooming as a way to social success posed a problem: given their large social groups of 150 or so, our earliest ancestors would have had to spend almost half their time grooming one another--an impossible burden. What Dunbar suggests--and his research, whether in the realm of primatology or in that of gossip, confirms--is that humans developed language to serve the same purpose, but far more efficiently. It seems there is nothing idle about chatter, which holds together a diverse, dynamic group--whether of hunter-gatherers, soldiers, or workmates.

Anthropologists have long assumed that language developed in relationships among males during activities such as hunting. Dunbar's original and extremely interesting studies suggest otherwise: that language in fact evolved in response to our need to keep up to date with friends and family. We needed conversation to stay in touch, and we still need it in ways that will not be satisfied by teleconferencing, email, or any other communication technology. As Dunbar shows, the impersonal world of cyberspace will not fulfill our primordial need for face-to-face contact.

From the nit-picking of chimpanzees to our chats at coffee break, from neuroscience to paleoanthropology, Grooming, Gossip, and the Evolution of Language offers a provocative view of what makes us human, what holds us together, and what sets us apart.

Unrivaled in the temperate latitudes of the world, China’s rich flora comprises 30,000 species of plants, and nowhere is this floral richness more evident than in western China. With its lush forests, meandering rivers, and majestic mountains, the west of China has been a center of plant exploration for over two centuries, giving rise to many well-known species of trees, shrubs, perennials, and bulbs that populate our parks and botanical institutes, including rhododendron, orchids, peonies, and roses.

            
Guide to the Flowers of Western China describes and illustrates more than two thousand species, from the common to the endemic to the extremely rare. Plant families are arranged following the latest DNA-based classification, making this pictorial guide— the largest and most comprehensive on western China ever published—essential for gardeners and plant scientists.

Celebrating the wealth of western China’s vast flora, this magnificent volume will enable the horticulturally inclined traveler (or armchair traveler) to identify many of the plants encountered in the wild.

"Endless forms most beautiful and most wonderful have been, and are being, evolved," Darwin famously concluded The Origin of Species, and for confirmation we look to...the guinea pig? How this curious creature and others as humble (and as fast-breeding) have helped unlock the mystery of inheritance is the unlikely story Jim Endersby tells in this book.

Biology today promises everything from better foods or cures for common diseases to the alarming prospect of redesigning life itself. Looking at the organisms that have made all this possible gives us a new way of understanding how we got here--and perhaps of thinking about where we're going. Instead of a history of which great scientists had which great ideas, this story of passionflowers and hawkweeds, of zebra fish and viruses, offers a bird's (or rodent's) eye view of the work that makes science possible.

Mixing the celebrities of genetics, like the fruit fly, with forgotten players such as the evening primrose, the book follows the unfolding history of biological inheritance from Aristotle's search for the "universal, absolute truth of fishiness" to the apparently absurd speculations of eighteenth-century natural philosophers to the spectacular findings of our day--which may prove to be the absurdities of tomorrow.

The result is a quirky, enlightening, and thoroughly engaging perspective on the history of heredity and genetics, tracing the slow, uncertain path--complete with entertaining diversions and dead ends--that led us from the ancient world's understanding of inheritance to modern genetics.
