The survival of the human species has improved significantly in modern times. During the last century, the mean survival of human populations in developed countries has increased more than during the preceding 5000 years. This improvement in survival was accompanied by an increase in the number of active years. In other words, the increase in mean life span was accompanied by an increase in health span. This is now accentuated by progress in medicine reducing the impact of physiologic events such as menopause and of patho logical processes such as atherosclerosis. Up to now,research on aging, whether theoretical or experimental, has not contributed to improvement in human survival. Actually, there is a striking contrast between these significant modifications in survival and the present knowledge of the mechanisms of human aging. Revealed by this state of affairs are the profound disagreements between gerontologists in regard to the way oflooking at the aging process. The definition of aging itself is difficult to begin with because of the variability of how it occurs in different organisms.

Squat lobsters of the superfamilies Chirostyloidea and Galatheoidea are highly visible crustaceans on seamounts, continental margins, shelf environments, hydrothermal vents and coral reefs. About 1000 species are known. They frequently feature in deep-sea images taken by submersibles and are caught in large numbers by benthic dredges. Some species are so locally abundant that they form ‘red tides’. Others support a variety of important fisheries. The taxonomy of squat lobsters has been intensively studied over the past few decades, making them one of the best known deepwater crustacean groups. As a result, they have attracted the attention of deep-sea ecologists who use them as proxies to test hypotheses about deepwater ecological processes and biogeography. Interest in squat lobsters now extends much more widely than the taxonomic research community and this work is a timely synthesis of what is known about these animals. The Biology of Squat Lobsters provides keys for identification and reviews the current state of knowledge of the taxonomy, evolution, life history, distribution, ecology and fisheries of squat lobsters. A striking feature of squat lobsters is their vivid coloration, which is revealed in a selection of spectacular images of different species.

The Biology of Nematodes synthesizes knowledge of the biology of free-living, plant-parasitic, and animal-parasitic nematodes. Contributed works by recognized researchers apply groundbreaking molecular techniques, many of which resulted from work on Caenorhabditis elegans, toward new approaches to the study of nematode worms. Topics covered include: ̈ Systematics and phylogeny ̈ Neuromuscular physiology ̈ Locomotion ̈ Sense organs ̈ Behavior ̈ Aging ̈ The nematode genome ̈ Survival strategies ̈ Immunology ̈ Epidemiology ̈ Structure and organization ̈ Gametes and fertilization ̈ Development ̈ Feeding, digestion, and metabolism

This laboratory manual is designed for an introductory biology course with a broad survey of basic laboratory techniques. The experiments and procedures are simple, safe, easy to perform and especially appropriate for large classes. Few experiments require a second class-meeting to complete the procedure. Each exercise includes many photographs, traditional topics and experiments that help students learn about life. Procedures within each exercise are numerous and discrete so that any exercise can be tailored to the needs of the students, the style of the instructor and the facilities available. New to this edition is a website. Each lab in the manual will have icons indicating which types of activities students will find on the Website. There will be icons for: Essential Study Partner modules, Animations, Activities, Readings, Maths Helps, BioCourse.Com, and a special password protected section for instructors that will house the Lab Resource Guide, alternative recipes for lab solutions and more.

"Biology of Freshwater Pollution," is a highly regarded overview of the subject aimed at advanced undergraduates and professionals. This latest edition provides an up-to-date summary of the whole field covering recent research, case studies and examples. The book begins by describing contrasting examples of pollution events. Individual chapters then deal with the major types of pollution introducing their sources, exploring their impacts on biological systems and water resources using contemporary examples, and discussing methods for mitigating impacts. Techniques used to investigate pollution are introduced throughout and the penultimate chapter deals extensively with the biological assessment of water quality. The final chapter looks at water resource management in the twenty-first century and the role of the biologist in that process. Features of the new edition* "New "coverage of current issues: biomarkers, endocrine disruptors, global warming* "New "chapter on biological pollution (invasive species) * "New "combined chapters bringing together material on toxic pollutions and energy and pollution * Management chapter extensively revised including the new organisation of the water industry and new regulatory frameworks* "New "case studies and examples * References have been extensively updated This book is aimed at advanced students in Aquatic and Applied Biology, Limnology and Environmental Science and scientists working in the water industry. Christopher Mason is a Professor of Biology at the University of Essex, UK. He has extensive research experience in the fields of pollution and conservation of freshwater and coastal environments, including eutrophication, heavy metals and organochlorines.
