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 The Phytochemical Landscape, 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, The Phytochemical Landscape offers an integrated approach to population-, community-, and ecosystem-level ecological processes.
"This timely and authoritative book offers a potentially transformative way of integrating several disparate ecological subfields to foster the pursuit of big-picture ecological science. It could only have been written by someone with Mark Hunter's vision and breadth and depth of knowledge."
– Oswald J. Schmitz, author of Resolving Ecosystem Complexity
"This is an excellent work of scholarship that makes important contributions to our understanding of phytochemistry, herbivory, and their links to ecosystem processes. Hunter's arguments are sound, his organization logical, and his conclusions insightful."
– Jennifer Schweitzer, University of Tennessee
