The Phytochemical Landscape: Linking Trophic Interactions and Nutrient Dynamics

Princeton University Press
Free sample

The dazzling variation in plant chemistry is a primary mediator of trophic interactions, including herbivory, predation, parasitism, and disease. At the same time, such interactions feed back to influence spatial and temporal variation in the chemistry of plants. In this book, Mark Hunter provides a novel approach to linking the trophic interactions of organisms with the cycling of nutrients in ecosystems.

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.

Recent Advances in Polyphenol Research

Volume 2

Edited by Santos-Buelga, Escribano-Bailon and Lattanzio

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.

Plant Alkaloids: A Guide to Their Discovery and Distribution serves as a record of both the positive and negative results obtained in the screening of more than 20,000 plant species for alkaloids in a forty-year search for new medicinal agents and other pharmacological substances. Designed to increase general knowledge of the Plant Kingdom, this book equips present and future generations of phytochemists with the skills and knowledge necessary for developing new alkaloid compounds. Recording the results of screening tests from approximately 400 genera of plants found primarily in zones beneath 45? N Latitude, Plant Alkaloids contributes to the efforts to calculate and safeguard the resources of the rainforests of the world. By offering results `from the field,'Plant Alkaloids surpasses the tradition of books on alkaloid chemistry that only emphasize the chemical and physical properties of known compounds, their established structures, biogenetic origins, taxonomic usefulness, and pharmacological actions. These results, in many cases, constitute the first record of the probable presence of alkaloids in the species under study. By documenting both positive and negative results, Plant Alkaloids directs the search for potentially new and useful compounds, while alleviating much of the time and expense of screening plants where results have already been obtained.An invaluable reference book for scientists in any of the life sciences, Plant Alkaloids provides a general index containing references to standard works on alkaloid chemistry and the subject?s vast literature. In addition to offering a description of the size of each plant family and its economic importance, this book also lists the genera and species of each plant tested according to accepted taxonomic names and notes disagreement over taxonomic assignment where it exists.
A plethora of different theories, models, and concepts make up the field of community ecology. Amid this vast body of work, is it possible to build one general theory of ecological communities? What other scientific areas might serve as a guiding framework? As it turns out, the core focus of community ecology—understanding patterns of diversity and composition of biological variants across space and time—is shared by evolutionary biology and its very coherent conceptual framework, population genetics theory. The Theory of Ecological Communities takes this as a starting point to pull together community ecology's various perspectives into a more unified whole.

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 number of species found at a given point on the planet varies by orders of magnitude, yet large-scale gradients in biodiversity appear to follow some very general patterns. Little mechanistic theory has been formulated to explain the emergence of observed gradients of biodiversity both on land and in the oceans. Based on a comprehensive empirical synthesis of global patterns of species diversity and their drivers, A Theory of Global Biodiversity develops and applies a new theory that can predict such patterns from few underlying processes.

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.
