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.
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.
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.
A Revised and Enlarged Edition of Norman C. Fassett's A Manual of Aquatic Plants, Volume I: Pteridophytes, Gymnosperms, and Angiosperms: Dicotyledons
This is by far the best and most comprehensive manual and illustrated guide to native and naturalized vascular plants—ferns, conifers, and flowering plants—growing in aquatic and wetland habitats in northeastern North America, from Newfoundland west to Minnesota and south to Virginia and Missouri. Published in two volumes, this long-awaited work completely revises and greatly expands Norman Fassett’s 1940 classic A Manual of Aquatic Plants, yet retains the features that made Fassett’s book so useful.
Features include:
* coverage of 1139 plant species, 1186 taxa, 295 genera, 109 families
* more than 600 pages of illustrations, and illustrations for more than 90% of the taxa
* keys for each species include references to corresponding illustrations
* habitat information, geographical ranges, and synonomy
* a chapter on nuisance aquatic weeds
* glossaries of botanical and habitat terms
* a full index for each volume
Wetland ecologists, botanists, resource managers, public naturalists, and environmentalists concerned with the preservation of wetland areas, which are increasingly threatened, will welcome this clear, workable, and comprehensive guide.

A Complete Reference Guide
From the Delaware River to the shores of Lake Erie, Pennsylvania's diverse watery habitats are home to more than 200 species of aquatic plants. In Aquatic Plants of Pennsylvania: A Complete Reference Guide, botanists Timothy A. Block and Ann Fowler Rhoads have assembled the first identification guide specific to the Keystone State yet useful throughout the Mid Atlantic region. Organized and written in a way that will make information easily accessible to specialists and nonspecialists alike, the book highlights the diversity and vital ecological importance of this group of plants, providing photographs, illustrations, descriptions, and identification keys for all emergent, floating-leaved, and submergent aquatic plants found in the Commonwealth.
An introductory chapter on aquatic plant ecology covers topics such as evolution, form, and reproduction of aquatic plants, vegetation zones, types of aquatic ecosystems, and rare and endangered species. Information on invasive plants, such as Eurasian water-milfoil and curly pondweed, that threaten Pennsylvania's aquatic ecosystems will be especially useful to watershed organizations, citizen monitoring projects, lake managers, and natural resource agency personnel. An illustrated identification key guides the reader through a series of steps to properly identify a specimen based on its characteristics. Each of the more than 200 listings provides a plant's taxonomy, detailed description, distribution map, and expert botanical illustrations. Many also include color photographs of the plants in their natural habitats.
