Biology of Sex Determination
Few of us know much about the biology of sex determination, but what could be more interesting than to discover how we are shaped into males and females? In this book, Elof Carlson tells the incredible story of the difficult quest to understand how the body forms girls and boys. Carlson's history takes us from antiquity to the present day to detail how each component of human reproduction and sexuality was identified and studied, how this knowledge enlarged our understanding of sex determination, and how it was employed to interpret such little understood aspects of human biology as the origin of intersex births.
Water Willows to Wax Myrtles
Veteran botanist, scientific author, and professor Robert H. Mohlenbrock brings the full depth of his expertise and scholarship to his latest book, Acanthaceae to Myricaceae: Water Willows to Wax Myrtles, the third of four volumes in the Aquatic and Standing Water Plants of the Central Midwest series. This easy-to-use illustrated reference guide covers aquatic and standing water plants for the states of Iowa, Illinois, Indiana, Ohio, Kansas, Missouri, Nebraska, and Kentucky (excluding the biologically distinct Cumberland Mountain region of eastern Kentucky), from spearmint to wintergreen, from aster to waterwort.
The volume identifies, describes, and organizes species in three groups, including truly aquatic plants, which spend their entire life with their vegetative parts either completely submerged or floating on the water’s surface; emergents, which are usually rooted under water with their vegetative parts standing above the water’s surface; and wetland plants, which live most or all of their lives out of water, but which can live at least three months in water.
Mohlenbrock lists the taxa alphabetically, and within each taxon, he describes the species with the scientific names he deems most appropriate (indicating if his opinion differs from that of the U.S. Fish and Wildlife Service), common names, identification criteria, line drawings, geographical distribution, habitat description, and official U.S. Fish and Wildlife Service wetlands designation as described by the National Wetland Inventory Section in 1988.
Acanthaceae to Myricaceae is an essential reference for state and federal employees who deal with environmental conservation and mitigation issues in aquatic and wetland plants. It is also a useful guide for students and instructors in college and university courses focusing on the identification of aquatic and wetland plants.
By focusing on the crucial role of environment in the process of adaptation, Robert Brandon clarifies definitions and principles so as to help make the argument of evolution by natural selection empirically testable. He proposes that natural selection is the process of differential reproduction resulting from differential adaptedness to a common selective environment.

A Language for Our Biotechnological Future
Biotechnological advancements during the last half-century have forced humanity to come to grips with the possibility of a post-human future. The ever-evolving opinions about how society should anticipate this biotechnological frontier demand a language that will describe our new future and discuss its ethics. After the Genome brings together expert voices from the realms of ethics, rhetoric, religion, and science to help lead complex conversations about end-of-life care, the relationship between sin and medicine, and the protection of human rights in a post-human world. With chapters on the past and future of the science-warfare narrative, the rhetoric of care and its effect on those suffering, black rhetoric and biotechnology, planning for the end of life, regenerative medicine, and more, After the Genome yields great insight into the human condition and moves us forward toward a genuinely humane approach to who we are and who we are becoming.
Six Big Questions about Evolution
Despite the ongoing cultural controversy in America, evolution remains a cornerstone of science. In this book, Francisco J. Ayala—an evolutionary biologist, member of the National Academy of Sciences, and winner of the National Medal of Science and the Templeton Prize—cuts to the chase in a daring attempt to address, in nontechnical language, six perennial questions about evolution: • Am I a Monkey? • Why Is Evolution a Theory? • What Is DNA? • Do All Scientists Accept Evolution? • How Did Life Begin? • Can One Believe in Evolution and God? This to-the-point book answers each of these questions with force. Ayala's occasionally biting essays refuse to lend credence to disingenuous ideas and arguments. He lays out the basic science that underlies evolutionary theory, explains how the process works, and soundly makes the case for why evolution is not a threat to religion. Brief, incisive, topical, authoritative, Am I a Monkey? will take you a day to read and a lifetime to ponder.
Aménagement forestier écosystémique : Approche d'aménagement qui vise à maintenir des écosystèmes sains et résilients en misant sur une diminution des écarts entre les paysages naturels et ceux qui sont aménagés afin d'assurer, à long terme, le maintien des multiples fonctions de l'écosystème et, par conséquent, de conserver les bénéfices sociaux et économique que l'on en retire. Voilà la définition de l’aménagement forestier écosystémique proposée dans cet ouvrage qui offre une synthèse des principaux concepts écologiques qui appuient cette approche. Il présente une revue des grands régimes de perturbations qui façonnent la dynamique naturelle de la forêt boréale et des exemples provenant de différentes régions du centre et de l’est du Canada. Plusieurs projets de mise en œuvre de stratégies d’aménagement écosystémique illustrent des enjeux de la foresterie actuelle et les solutions que cette nouvelle approche peut apporter. En somme, la dynamique forestière dans son ensemble peut servir de guide à l’aménagement forestier. Une planification des interventions inspirée de la forêt facilitera la conciliation entre la récolte ligneuse et les intérêts des autres utilisateurs de la forêt.
If you travel the open ocean anywhere in the tropics, you are very likely to see flyingfish. These beautifully colored “ocean butterflies” shoot out of the water and sail on majestic, winglike pectoral fins to escape from predators such as dolphins, swordfish, and tuna. Some can travel for more than six hundred feet per flight. Yet despite their prevalence in warm ocean waters and their vital role in the tropical food chain, surprisingly little is known about flyingfish—more than 60 species are said to exist, but nobody is sure of the number. This beautifully illustrated book presents flyingfish as you’ve never seen them before. It features more than 90 stunning color photos by renowned naturalist Steve Howell, as well as a concise and accessible text that explores the natural history of flyingfish, where they can be found, how and why they fly, what colors they are, what they eat and what eats them, and more.
The ideal gift for fish lovers, seasoned travelers, and armchair naturalists alike, this first-of-its-kind book provides a rare and incomparable look at these spectacular marine creatures.
The Conservation Status of United States Species
This benchmark volume documents in comprehensive detail a major environmental crisis: rapidly declining amphibian populations and the disturbing developmental problems that are increasingly prevalent within many amphibian species. Horror stories on this topic have been featured in the scientific and popular press over the past fifteen years, invariably asking what amphibian declines are telling us about the state of the environment. Are declines harbingers of devastated ecosystems or simply weird reflections of a peculiar amphibian world?
This compendium—presenting new data, reviews of current literature, and comprehensive species accounts—reinforces what scientists have begun to suspect, that amphibians are a lens through which the state of the environment can be viewed more clearly. And, that the view is alarming and presages serious concerns for all life, including that of our own species.
The first part of this work consists of more than fifty essays covering topics from the causes of declines to conservation, surveys and monitoring, and education. The second part consists of species accounts describing the life history and natural history of every known amphibian species in the United States.
The Adaptive Dynamics Approach and Its Applications
Quantitative approaches to evolutionary biology traditionally consider evolutionary change in isolation from an important pressure in natural selection: the demography of coevolving populations. In Analysis of Evolutionary Processes, Fabio Dercole and Sergio Rinaldi have written the first comprehensive book on Adaptive Dynamics (AD), a quantitative modeling approach that explicitly links evolutionary changes to demographic ones. The book shows how the so-called AD canonical equation can answer questions of paramount interest in biology, engineering, and the social sciences, especially economics.
After introducing the basics of evolutionary processes and classifying available modeling approaches, Dercole and Rinaldi give a detailed presentation of the derivation of the AD canonical equation, an ordinary differential equation that focuses on evolutionary processes driven by rare and small innovations. The authors then look at important features of evolutionary dynamics as viewed through the lens of AD. They present their discovery of the first chaotic evolutionary attractor, which calls into question the common view that coevolution produces exquisitely harmonious adaptations between species. And, opening up potential new lines of research by providing the first application of AD to economics, they show how AD can explain the emergence of technological variety.
Analysis of Evolutionary Processes will interest anyone looking for a self-contained treatment of AD for self-study or teaching, including graduate students and researchers in mathematical and theoretical biology, applied mathematics, and theoretical economics.
A World View through History
Drawing on the latest research in archaeozoology, archaeology, and molecular biology, Animals as Domesticates traces the history of the domestication of animals around the world. From the llamas of South America and the turkeys of North America, to the cattle of India and the Australian dingo, this fascinating book explores the history of the complex relationships between humans and their domestic animals. With expert insight into the biological and cultural processes of domestication, Clutton-Brock suggests how the human instinct for nurturing may have transformed relationships between predator and prey, and she explains how animals have become companions, livestock, and laborers. The changing face of domestication is traced from the spread of the earliest livestock around the Neolithic Old World through ancient Egypt, the Greek and Roman empires, South East Asia, and up to the modern industrial age.
