Book Description
Physiology and biochemistry of male reproductive function and semen became the main area of my research in 1944, after my attention was finally diverted frorp. animal cells in general, to mammalian spermatozoa specifically~ Ever since, the interest has remained largely focussed on reproductive probletns in mammals, the work continuing mostly at the University of Cambridge, where I was privileged to hold also the Marshall Walton Professorship in Physiology of Reproduction. This work led to the publication of three books, The Biochemistry of Semen (Methuen 1954), The Biochemistry of Semen and of the Male Reproductive Tract (Methuen 1964) and lately, in co authorship with my wife, Dr. Cecilia Lutwak-Mann, Male Re productive Function and Semen - Themes and Trends in Phys iology, Biochemistry and Investigative Andrology (Springer Verlag 1981). In 1960, thanks to the Lalor Foundation, I was able to avail myself for the first time of a chance to visit the Marine Biological Laboratory at Woods Hole and there to take part in a study of reproduction in marine animals. Ever since, first as Visiting Professor of Biology at the State University of Florida, and later as the Walker Ames Professor and frequent visitor to the Department of Zoology at the University of Washington in Seattle, it has been my good fortune to sustain this pew interest and to pursue it further.

Book Description
Consisting of more than six thousand species, amphibians are more diverse than mammals and are found on every continent save Antarctica. Despite the abundance and diversity of these animals, many aspects of the biology of amphibians remain unstudied or misunderstood. The Ecology and Behavior of Amphibians aims to fill this gap in the literature on this remarkable taxon. It is a celebration of the diversity of amphibian life and the ecological and behavioral adaptations that have made it a successful component of terrestrial and aquatic ecosystems. Synthesizing seventy years of research on amphibian biology, Kentwood D. Wells addresses all major areas of inquiry, including phylogeny, classification, and morphology; aspects of physiological ecology such as water and temperature relations, respiration, metabolism, and energetics; movements and orientation; communication and social behavior; reproduction and parental care; ecology and behavior of amphibian larvae and ecological aspects of metamorphosis; ecological impact of predation on amphibian populations and antipredator defenses; and aspects of amphibian community ecology. With an eye towards modern concerns, The Ecology and Behavior of Amphibians concludes with a chapter devoted to amphibian conservation. An unprecedented scholarly contribution to amphibian biology, this book is eagerly anticipated among specialists.

Book Description
Sexual Biology and Reproduction in Crustaceans covers crustacean reproduction as it deals with the structural morphology of the gamete-producing primary sex organs, such as the testis and ovary, the formation and maturation of gametes, their fusion during fertilization, and embryonic development that lead to the release of larvae. Constituting a diverse assemblage of animals, crustaceans are best known by their common representatives, such as shrimps, lobsters, and crabs, but also include many more less familiar, but biologically important forms. This work covers the variety of ways in which both male and female gametes are produced by evolving different sexual systems in crustaceans, the range of reproductive systems, and the accordingly, and highly diverse, mechanistic modes of sex determination. In addition, the book features such topics as genetic and environmental determinants in sex determination pattern, variability of mechanisms of fertilization among different species, the origin of different mating systems, the associated mating and brooding behaviors, and the adaptive ability to different environmental conditions with discussion on the evolutionary ecology of social and sexual systems in certain species, which have shown eusocial tendencies, similar to social insects. Marine species occupying diversified ecological niches in tropical and temperate zones reproduce under definitive environmental conditions. Therefore, reproductive ecology of different crustaceans inhabiting different ecological niches also constitutes another important aspect of the work, along with yolk utilization and embryogenesis leading to release of different larval forms, which reflect on their aquatic adaptability. Forms a valuable source of recent references on the current research in crustacean reproductive physiology Covers various mating and breeding systems, providing illustrative examples for sexual selection, parental care of developing eggs and embryos, and the evolution of other reproductive behaviors Features contributions written in the form of review articles, enabling readers to not only gain information in the respective subject, but also help them stimulate ideas in their chosen field of research Includes a glossary created by the author to define technical terms Demonstrates the ability of crustacean species to serve as useful model systems for other organisms, to investigate issues related to sexual conflict, mate choice, and sperm competition Discusses techniques in endocrine research to help researchers in aquaculture develop protocols in the control of reproduction

Book Description
This book is a timely compilation of synthesized information on behaviourally fascinating and economically important mites. The book gives much attention to fundamental aspects of eriophyoid anatomy, behaviour, ecology and even systematics, as bases for understanding the ways of life of eriophyoid mites and their effects on host plants; in turn, this will lead to developing the most appropriate means of regulating mites as detrimental or beneficial organisms. It presents new views intended to stimulate interest in eriophyoids and their enemies, and it points to areas where further research is needed. This book is intended for extension workers, experts of acarology and plant protection as well as students, teachers and researchers. It stimulates readers to critically test the view presented and aimes ultimately toward environmentally safe, sustainable and economically efficient means of regulating detrimental and beneficial eriophyoid mites.

Book Description
This special volume of Advances in Marine Biology covers in detail the biology of calanoid copepods. Copepods are probably the most numerous multicellular organisms on earth. They are aquatic animals that live in both marine and fresh water, and are of prime importance in marine ecosystems as they form a direct link between phytoplankton and fish. This volume is essential for all marine biologists. Advances in Marine Biology contains up-to-date reviews of all areas of marine science, including fisheries science and macro/micro fauna. Each volume contains peer-reviewed papers detailing the ecology of marine regions.
