Reproductive Biology and Phylogeny of Lizards and Tuatara is a remarkable compendium of chapters written by the world's leading experts from over four continents. The book begins with a chapter recounting historical discoveries in reproductive biology and a review of phylogenetics and up-to-date hypotheses concerning evolutionary relationships among lizards.

Following these chapters are detailed reviews with additional new data concerning chemical communication, sexual selection, reproductive cues, female reproductive anatomy, female reproductive cycles, oogenesis, parthenogenesis, male...

This volume explores the latest developments in a novel area of molecular biology and a hot topic in the field of oncology: cancer stem cells. These chapters from expert contributing authors present concepts such as the universal stem cell, new molecular pathways, new targeted agents, the different roles that cancer stem cells seem to have according to the organ they are placed in, and the future role that targeting cancer stem cells may have in the management of patients in the clinic.

Exploring the latest research including new data from randomized trials, this book examines...

Evolution by Tumor Neofunctionalization explores the possibility of the positive role of tumors in evolution of multicellular organisms. This unique perspective goes beyond recent publications on how evolution may influence tumors, to consider the possible role of tumors in evolution.

Widespread in nature tumors represent a much broader category than malignant tumors only. The majority of tumors in humans and other animals may never undergo malignant transformation. Tumors may differentiate with the loss of malignancy, and malignant tumors may spontaneously regress. Cellular...

The southwestern Australian flora is unique in the world, not only for its biodiversity and endemism, but also for its functional biodiversity. It also contains the world s most nutrient-impoverished soils, has a prolonged-summer period and the vegetation is extremely fire-prone. These conditions have engendered an array of survival adaptations that have evolved in these harsh conditions across a diverse range of species. It is well recognised that the southwest flora has the toughest and most spiny vegetation of the world, the greatest number of species that store their seeds in woody...

Infectious fungal diseases continue to take their toll in terms of human suffering and enormous economic losses. Invasive infections by opportunistic fungal pathogens are a major cause of morbidity and mortality in immuno-compromised individuals. At the same time, plant pathogenic fungi have devastating effects on crop production and human health. New strategies for antifungal control are required to meet the challenges posed by these agents, and such approaches can only be developed through the identification of novel biochemical and molecular targets. However, in contrast to bacterial...

To celebrate the Center for Perinatal Biology's 40th Anniversary, an illustrious group gathered at Loma Linda University in February 2013. That gathering of experts and this volume of the proceedings are a tribute to the founder of the Center, Lawrence D. Longo, M.D. These chapters present contributions from individuals who in some way or another were influenced by Dr. Longo. Covering a wide range of topics, and illustrating the diversity of thinking and scientific interests, these proceedings address basic science through to clinical problems in the developmental programming of health and...

Fish constitute an important natural renewable resource and any reduction in their ability to propagate as a result of human interference may have significant socioeconomic consequences. The negative effect of human activity on sex differentiation and reproductive output in fish is so diverse that it has been difficult to encompass it in a single book. This book serves as the first attempt to do so.

Unlike in mammals, the expression of a host of sex differentiation genes in fish is mostly controlled by environmental factors. Not surprisingly, environmental sex differentiation is...

This volume addresses recent developments in weed science. These developments include conservation agriculture and conservation tillage, climate change, environmental concerns about the runoff of agrochemicals, resistance of weeds and crops to herbicides, and the need for a vastly improved understanding of weed ecology and herbicide use. The book provides details on harnessing knowledge of weed ecology to improve weed management in different crops and presents information on opportunities in weed management in different crops. Current management practices are also covered, along with...

"Population Aging: The Transformation of Societies" presents an overview and international comparison of the causes, consequences and policy implications of one of the major processes of change in contemporary societies. It provides a foundation for understanding and reflecting on key demographic and social trends, together with related theoretical and policy frameworks that are important in explaining changes and designing informed responses. With particular reference to countries that have the oldest or largest aged populations, the book presents a synthesis of research on population...
