Arrowhead Life Cycles is a visual guide to the many phases that most arrowheads go through during the course of their use. It features approximately 150 detailed illustrations of different sequences and scenarios in the life cycles of arrowheads, spearheads, dart points, and knives. By gaining an understanding of how these stages affect the appearance of an arrowhead, accurate identification of the point type becomes easier. Included are visual explanations of tools and techniques for making arrowheads, and reconstructions of the spear shafts and knife handles in which the arrowheads might have been hafted. PUBLISHER'S NOTE: The material contained in this book is also featured, with much more additional material, in "Arrowheads: A Beginner's Guide" also by Tim Anderson.

Crustaceans are increasingly used as model organisms in all fields of biology, as few other taxa exhibit such a variety of body shapes and adaptations to particular habitats and environmental conditions. Life Histories is the fifth volume in The Natural History of the Crustacea series. An understanding of life histories is crucial to understanding the biology of this fascinating invertebrate group. Written by internationally recognized experts studying a wide range of crustacean taxa and topics, this volume synthesizes current research in a format that is accessible to a wide scientific audien.

Crustaceans are increasingly being used as model organisms in all fields of biology, including neurobiology, developmental biology, animal physiology, evolutionary ecology, biogeography, and resource management. Crustaceans have a very wide range of phenotypes and inhabit a diverse array of environments, ranging from the deep sea to high mountain lakes and even deserts. The evolution of their life histories has permitted crustaceans to successfully colonize this variety of habitats. Few other taxa exhibit such a variety of life histories and behavior. A comprehensive overview of their life histories is essential to the understanding of many aspects of their success in marine and terrestrial environments. This volume provides a general overview of crustacean life histories. Crustaceans have particular life history adaptations that have permitted them to conquer all environments on earth. Crustacean life cycles have evolved to maximize fecundity, growth, and ageing, in a wide range of environmental conditions. Individual contributions contrast benefits and costs of different life histories including sexual versus asexual production, semelparity versus iteroparity, and planktonic larvae versus direct development. Important aspects of particular behaviors are presented (e.g. migrations, defense and territorial behaviors, anti-predator behavior, symbiosis).

Fundamentals of Weed Science provides an introduction to the basic principles of weed science for undergraduate courses. It discusses several aspects of weed biology and control, and traces the history of herbicide development. The book begins with an introduction to weeds, covering their definition, characteristics, harmful aspects, and the cost of weed control. This is followed chapters on weed classification, the uses of weeds, weed biology, weed ecology, allelopathy, the significance of plant competition, weed management and control methods, and biological weed control. Later chapters deal with herbicidesthe most important weed control tools and the ones with the greatest potential for untoward effects. Students of weed science must understand herbicides and the factors governing their use as well as the potential for misuse. These chapters discuss chemical weed control, the properties and uses of herbicides, factors affecting herbicide performance, herbicide application, herbicide formulation, ecological impact of herbicides, pesticide registration and legislation, weed management systems, and the future of weed science.

This 2e of Toxoplasma gondii reflects the significant advances in the field in the last 5 years, including new information on the genomics, epigenomics and proteomics of T. gondii as well as a new understanding of the population biology and genetic diversity of this organism. T. gondii remains the best model system for studying the entire Apicomplexa group of protozoans, which includes Malaria, making this new edition essential for a broad group of researchers and scientists. Toxoplasmosis is caused by a one-celled protozoan parasite known as T. gondii. The infection produces a wide range of clinical syndromes in humans, land and sea mammals, and various bird species. Most humans contract toxoplasmosis by eating contaminated, raw or undercooked meat (particularly pork), vegetables, or milk products; by coming into contact with the T. gondii eggs from cat feces; or by drinking contaminated water. The parasite damages the ocular and central nervous systems, causing behavioral and personality alterations as well as fatal necrotizing encephalitis. It is especially dangerous for the fetus of an infected pregnant woman and for individuals with compromised immune systems, such as HIV-infected patients. Completely updated, the 2e presents recent advances driven by new information on the genetics and genomics of the pathogen Provides the latest information concerning the epidemiology, diagnosis, treatment and prevention of toxoplasmosis Offers a single-source reference for a wide range of scientists and physicians working with this pathogen, including parasitologists, cell and molecular biologists, veterinarians, neuroscientists, physicians, and food scientists
