Hunter introduces the concept of the "phytochemical landscape"—the shifting spatial and temporal mosaic of plant chemistry that serves as the nexus between trophic interactions and nutrient dynamics. He shows how plant chemistry is both a cause and consequence of trophic interactions, and how it also mediates ecosystem processes such as nutrient cycling. Nutrients and organic molecules in plant tissues affect decomposition rates and the fluxes of elements such as carbon, nitrogen, and phosphorus. The availability of these same nutrients influences the chemistry of cells and tissues that plants produce. In combination, these feedback routes generate pathways by which trophic interactions influence nutrient dynamics and vice versa, mediated through plant chemistry. Hunter provides evidence from terrestrial and aquatic systems for each of these pathways, and describes how a focus on the phytochemical landscape enables us to better understand and manage the ecosystems in which we live.
Essential reading for students and researchers alike, this book offers an integrated approach to population-, community-, and ecosystem-level ecological processes.

Plant phenolics are secondary metabolites that constitute one of the most common and widespread groups of substances in plants. Polyphenols have a large and diverse array of beneficial effects on both plants and animals. For example they are famous as antioxidants, hormones, constituents of essential oils and natural neurotransmitters.
Sponsored by Groupe Polyphenols, this publication, which is the second volume in this ground-breaking series, is edited by Celestino Santos-Buelga, Maria Teresa Escribano-Bailon, and Vincenzo Lattanzio, who have drawn together an impressive list of internationally respected authors, each providing cutting edge chapters covering some of the major topics of recent research and interest.
Information included in this important new addition to the series include the following areas:
• Flavonoid chemistry of the leguminosae
• Chemistry and biological activity of ellagitannins
• Chemistry and function of anthocyanins in plants
• An update of chemical pathways leading to new phenolic pigments during wine ageing
• Metabolic engineering of the flavonoid pathway
• The translation of chemical properties of polyphenols into biological activity with impacts in human health
• Plant phenolic compounds controlling leaf movement
• Biological activity of phenolics in plants
Chemists, biochemists, plant scientists, pharmacognosists and pharmacologists, food scientists and nutritionists will all find this book an invaluable resource. Libraries in all universities and research establishments where these subjects are studied and taught should have copies on their shelves.
This book is meticulously organised and richly illustrated, having over 1,000 full-colour illustrations and 500 photographs. It is divided into five parts covering: Compartments, Cell Reproduction, Energy Flow, Metabolic and Developmental Integration, and Plant Environment and Agriculture. Specific changes to this edition include:Completely revised with over half of the chapters having a major rewrite. Includes two new chapters on signal transduction and responses to pathogens. Restructuring of section on cell reproduction for improved presentation. Dedicated website to include all illustrative material.
Biochemistry and Molecular Biology of Plants holds a unique place in the plant sciences literature as it provides the only comprehensive, authoritative, integrated single volume book in this essential field of study.
Mark Vellend builds a theory of ecological communities based on four overarching processes: selection among species, drift, dispersal, and speciation. These are analogues of the four central processes in population genetics theory—selection within species, drift, gene flow, and mutation—and together they subsume almost all of the many dozens of more specific models built to describe the dynamics of communities of interacting species. The result is a theory that allows the effects of many low-level processes, such as competition, facilitation, predation, disturbance, stress, succession, colonization, and local extinction to be understood as the underpinnings of high-level processes with widely applicable consequences for ecological communities.
Reframing the numerous existing ideas in community ecology, The Theory of Ecological Communities provides a new way for thinking about biological composition and diversity.
The authors show that global patterns of biodiversity fall into four consistent categories, according to where species live: on land or in coastal, pelagic, and deep ocean habitats. The fact that most species groups, from bacteria to whales, appear to follow similar biogeographic patterns of richness within these habitats points toward some underlying structuring principles. Based on empirical analyses of environmental correlates across these habitats, the authors combine aspects of neutral, metabolic, and niche theory into one unifying framework. Applying it to model terrestrial and marine realms, the authors demonstrate that a relatively simple theory that incorporates temperature and community size as driving variables is able to explain divergent patterns of species richness at a global scale.
Integrating ecological and evolutionary perspectives, A Theory of Global Biodiversity yields surprising insights into the fundamental mechanisms that shape the distribution of life on our planet.
This textbook provides the busy clinician with a 'one stop' comprehensive guide to women's health that includes essential components of the history, diagnostic workup, treatment, and management guidelines for most common health issues and problems specific to providing gynecologic care to women. Clinicians will welcome the updated clinical content and additional resources and educational recommendations.

This landmark 10th edition of a highly respected classic and best-selling reference provides current guidelines for primary care management of common gynecological conditions across the age span. The fully revised new edition provides well-organized, concise, and easier-to-access evidence-based practice guidelines for use in community and ambulatory settings. It has been written by nurse practitioners with over 90 years of combined experience in women's health, and integrates the knowledge of noted experts for each topic.
This 10th edition offers new information for all guidelines and presents essential new guidelines for sexually transmitted diseases, family planning, medical abortion, breast cancer screening and other breast conditions, osteoporosis, menopause, incontinence, sexual dysfunction, complementary and alternative therapies, smoking cessation, abuse and violence screening, abuse screening for disabled women, and Pap, PCOS, and preconception care. The guide also contains an entirely new chapter on annual well woman visits, an enhanced mental health chapter detailing discontinuation of SSRIs/SNRIs, recent guidelines from the World Health Organization regarding contraception, and more. This book will be of value to graduate nursing programs, all nurse practitioners, and nurse midwives.Key Features: Reflects best practice standards of care empirically proven to improve patient outcomes by at least 28% Provides quick and easy access to crucial clinical information through use of an intuitive alpha organization, a consistent format, and new spiral binding Contains new Well Woman Annual Visit chapter Patient education handouts are included in book AND are available in printable PDF format online Contains completely new bibliographies reflecting the latest literature and evidence-based practice, and relevant websites "
