Plasticity in host plant preferences might promote sympatric speciation of herbivorous insects if plants affect mating signals and thus, lead to assortative mating. The general aim of this thesis is to understand the causes and consequences of phenotypic plasticity of mating recognition systems of herbivorous insects. The investigated species are the syntopic leaf beetles Phaedon cochleariae and P. armoraciae which have a common host plant range, but use divergent host species when occurring at the same site. Their sexual behavior is mediated by their cuticular hydrocarbon (CHC) profiles which function as contact pheromones for mate and species recognition. Behavioral bioassays and chemical analyses are used to study the question whether the host plant species affects the CHC pattern of the beetles, and thus, their mate recognition. Within a species, males prefer mating with females feeding on the same host plant species to mating with females feeding on an alternative host plant. Sexual isolation between species ceases when beetles feed upon the same host plant species. A discriminant analysis reveals that the beetles' quantitative composition of CHC profiles clearly differ in dependence of sex, host plant and insect species. However, the profiles of the two beetle species are more similar when feeding upon the same host plant species. These findings give rise to the idea that plant-induced phenotypic divergence in mate recognition cues of herbivorous insects may act as an early barrier to gene flow between insect populations on different host species, thus preceding genetic divergence and thus, promoting ecological speciation

Phenotypically plastic traits include morphological, behavioral, and physiological characteristics. These environmentally induced differences can serve as the raw products upon which natural selection acts. Phenotypic plasticity in short deserves increase

Available in PDF, EPUB and Kindle. Book excerpt: This book explores the profound importance of phenotypic plasticity as a central organizing theme for understanding biology. Chapters take a broad, integrative approach to explain how physical and biological environmental stimuli (temperature, photoperiod, nutrition, population density, predator presence, etc.), influence insect biochemical, physiological, learning, and developmental processes, altering phenotype, which then influences performance, ecology, life-history, survival, fitness, and subsequent evolution. Topics include endocrinology, development, body size, allometry, polyphenism, reproduction, reproductive and life-history tradeoffs, alternative mating and life-history strategies, density-dependent prophylaxis, physiological adaptation, acclimation, homeostasis, heat-shock proteins, learning, adaptive anti-predator behavior, and evolution of phenotypic plasticity.

Available in PDF, EPUB and Kindle. Book excerpt: A unique and critical analysis of the wealth of research conducted on the biology, biochemistry and chemical ecology of the rapidly growing field of insect cuticular hydrocarbons. Authored by leading experts in their respective fields, the twenty chapters show the complexity that has been discovered in the nature and role of hydrocarbons in entomology. Covers, in great depth, aspects of chemistry (structures, qualitative and quantitative analysis), biochemistry (biosynthesis, molecular biology, genetics, evolution), physiology, taxonomy, and ecology. Clearly presents to the reader the array of data, ideas, insights and historical disagreements that have been accumulated during the past half century. An emphasis is placed on the role of insect hydrocarbons in chemical communication, especially among the social insects. Includes the first review on the chemical synthesis of insect hydrocarbons. The material presented is a major resource for current researchers and a source of ideas for new researchers.

Available in PDF, EPUB and Kindle. Book excerpt: "Half of all insect species are dependent on living plant tissues, consuming about 10% of plant annual production in natural habitats and an even greater percentage in agricultural systems, despite sophisticated control measures. Plants are generally remarkably well-protected against insect attack, with the result that most insects are highly specialized feeders. The mechanisms underlying plant resistance to invading herbivores on the one side, and insect food specialization on the other, are the main subjects of this book. For insects these include food-plant selection and the complex sensory processes involved, with their implications for learning and nutritional physiology, as well as the endocrinological aspects of life cycle synchronization with host plant phenology. In the case of plants exposed to insect herbivores, they include the activation of defence systems in order to minimize damage, as well as the emission of chemical signals that may attract natural enemies of the invading herbivores and may be exploited by neighbouring plants that mount defences as well." "Insect-Plant Biology discusses the operation of these mechanisms at the molecular and organismal levels, in the context of both ecological interactions and evolutionary relationships. In doing so, it uncovers the highly intricate antagonistic and mutualistic interactions that have evolved between plants and insects. The book concludes with a chapter on the application of our knowledge of insect-plant interactions to agricultural production." "This multidisciplinary approach will appeal to students in agricultural entomology, plant sciences, ecology, and indeed anyone interested in the principles underlying the relationships between the two largest groups of organisms on earth: plants and insects."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Book excerpt: Almost 20 years after the first MEDPINE book "Ecology, biogeography and management of Pinus halepensis and P. brutia forest ecosystems in the Mediterranean basin "(Ne'eman and Trabaud, 2000) was published, this new book presents up-to-date and state of the art information, covering a wide range of topics concerning Mediterranean pine trees growing in native and planted forests, their ecosystems and management. This will be an essential source of scientific information for learning, exploring planning and managing mediterranean pine and mixed forests. We focus on: genetics, adaptation, distribution and evolution; ecophysiology and drought resistance; pine and mixed forest ecosystems; forest dynamics biodiversity and biotic interactions; fire ecology; ecosystem services and policy; afforestation and management; all under the effect of global climate change. While forests are studied mainly in temperate and tropical zones, in the light of current climate change, focusing on Mediterranean forests growing in semi-humid to semi-arid zones is more important than ever. This book will include mostly review chapters (and two outstanding case studies) contributed by leading scientists, foresters and managers, and will serve as a scientific textbook for students of biology, agriculture and forestry, researchers of ecology forestry and related fields, forest managers, policy and decision makers.
