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, an...
Fully revised and updated to include new topical study areas, the second edition of the successful text the Ecology of Insects provides a balanced treatment of the theory and practice of pure and applied insect ecology. Includes new topical areas of insect ecology and provides greater coverage of physiological, genetic, molecular, and ecosystem aspects of insect ecology Concepts include the foundations of evolutionary ecology and population dynamics in ecosystem science as they are applied to topics such as climate change, conservation and biodiversity, epidemiology and pest management Fully updated and revised throughout, this new edition refers to primary literature and real world examples.

"Investigative Journalism means the unveiling of matters that are concealed either deliberately by someone in a position of power, or accidentally, behind a chaotic mass of facts and circumstances - and the analysis and exposure of all relevant facts to the public. In this way investigative journalism crucially contributes to freedom of expression and freedom of information, which are at the heart of UNESCO's mandate. The role media can play as a watchdog is indispensable for democracy and it is for this reason that UNESCO fully supports initiatives to strengthen investigative journalism throughout the world. I believe this publication makes a significant contribution to promoting investigative journalism and I hope it will be a valuable resource for journalists and media professionals, as well as for journalism trainers and educators." -- Jānis Kārklinš, Assistant Director-General for Communication and Information, UNESCO, Preface, page 1.
An examination of families and schools in South Africa, revealing how the marketisation of schooling works to uphold the privilege of whiteness.
Natural variability in plants and animals. Phenotypic and genotypic variation in plants and animals. Resource distribution, reproduction, and popultion dynamics. Resource distribution and patterns in animal-plant communities. Evolutionary responses to the distribution of resources.
An understanding of the dynamics of populations is critically important to ecologists, evolutionary biologists, wildlife managers, foresters, and many other biologists. This edited treatise brings together the latest research on how populations fluctuate in size, the factors that drive these changes, and the theories explaining how populations are regulated. The book also includes specific chapters dealing with insects of economic importance.

Aboveground interactions between plants and organisms have served as a foundation of ecological and evolutionary theories. Accumulating evidence suggests that interactions that occur belowground can have immense influence on eco-evolutionary dynamics of plants. Despite the increasing awareness among scientists of the importance of belowground interactions for plant performance and community dynamics, they have received considerably less theoretical and empirical attention compared to aboveground interactions. In this eBook we aim to highlight the overlooked roles of belowground interactions and outline their myriad ecological roles, from affecting soil health through impacting plant interactions with above-ground fauna. This eBook with 18 articles and an Editorial includes conceptual contribution together with original research work. The chapters are exploring the roles of belowground biotic interactions, in the context of ecological processes both below- and above-ground.
Intended to bridge the gap between theory and the real world of crime and criminal justice, discussing what crime is, why criminologists think people commit crime, and how society feels it should handle these digressions.
