Phenotypic Plasticity of Cuticular Hydrocarbons in Herbivorous Insects by Tobias Otte Pdf

Speciation of herbivorous insects may be driven by specialization on host plants. 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

Phenotypic Plasticity of Insects by Douglas Whitman,T. N. Ananthakrishnan Pdf

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.

Insect-Plant Biology by Louis M. Schoonhoven,Joop J. A. van Loon,Marcel Dicke Pdf

"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.

Pines and Their Mixed Forest Ecosystems in the Mediterranean Basin by Gidi Ne'eman,Yagil Osem Pdf

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.

Behavioral and Chemical Ecology by Wen Zhang,Hong Liu Pdf

Behavioural ecology is the study of the ecological and evolutionary basis for animal behaviour, and the roles of behaviour in enabling an animal to adapt to its environment. Chemical ecology, on the other hand, is the study of the chemicals involved in the interactions of living organisms. It focuses on the production of and response to signalling molecules and toxins. This book discusses how a comprehensive knowledge of an organisms' systematics, biology, ecology, and bioactivity of their secondary metabolites may act as a guide for chemical analyses of certain metabolites. It describes how rather simple bioassays can be highly efficient ways to increase our understanding of multitrophic interactions. This book also focuses on the ecological aspects of fungal secondary metabolites in the interactions between fungi and animals. The different aspects of animal interactions are investigated further with mushrooms to clarify the relevance of mushroom poisons. Also explored are some functional explanations of insect cognition. Given that all animals live on an Earth with many enduring properties, they might universally show certain adaptations accommodating these properties of the world. Other chapters in this book examine cuticular hydrocarbons and how they affect insect behaviour, a discussion of the potential of salivary protein profiles for non-invasively and dynamically accessing mammal feeding behaviour, the chemical ecology of phytophagous insects and their defence strategies, and the evolved behaviours of migrant birds to adapt to environmental variability.

Bark and Wood Boring Insects in Living Trees in Europe, a Synthesis by François Lieutier,Keith R. Day,Andrea Battisti,Jean-Claude Grégoire,Hugh F. Evans Pdf

For the first time, a synthesis on the research work done in Europe on all Bark And Wood Boring Insects In Living Trees (BAWBILT) is presented. As final product of a four-year research project gathering together 100 scientists from 24 countries, the book is the fruit of a real collective synthesis in which all European specialists have participated. It reviews and comments on all the European literature, while considering the biological (trees, insects, associated organisms, and their relationships) and forest management aspects. However, although focused on the European forest, it also compares the available information and interpretations to those concerning similar species in other continents. It ends with propositions of research priorities for Europe. The book is directed to all scientists and students concerned with forest entomology and ecology, as well as to forest managers and all scientific public interested in forest biology.

Plant Communication from an Ecological Perspective by František Baluška,Velemir Ninkovic Pdf

Since the concept of allelopathy was introduced almost 100 years ago, research has led to an understanding that plants are involved in complex communicative interactions. They use a battery of different signals that convey plant-relevant information within plant individuals as well as between plants of the same species or different species. The 13 chapters of this volume discuss all these topics from an ecological perspective. Communication between plants allows them to share physiological and ecological information relevant for their survival and ?tness. It is obvious that in these very early days of ecological plant communication research we are illuminating only the ‘tip of iceberg’ of the communicative nature of higher plants. Nevertheless, knowledge on the identity and informative value of volatiles used by plants for communication is increasing with breath-taking speed. Among the most spectacular examples are sit- tions where plant emitters warn neighbours about a danger, increasing their innate immunity, or when herbivore-attacked plants attract the enemies of the herbivores (‘cry for help’ and ‘plant bodyguards’ concepts). It is becoming obvious that plants use not only volatile signals but also diverse water soluble molecules, in the case of plant roots, to safeguard their evolutionary success and accomplish self/non-self kin rec- nition. Importantly, as with all the examples of biocommunication, irrespective of whether signals and signs are transmitted via physical or chemical pathways, plant communication is a rule-governed and sign-mediated process.

Neurobiology of Chemical Communication by Carla Mucignat-Caretta Pdf

Intraspecific communication involves the activation of chemoreceptors and subsequent activation of different central areas that coordinate the responses of the entire organism—ranging from behavioral modification to modulation of hormones release. Animals emit intraspecific chemical signals, often referred to as pheromones, to advertise their presence to members of the same species and to regulate interactions aimed at establishing and regulating social and reproductive bonds. In the last two decades, scientists have developed a greater understanding of the neural processing of these chemical signals. Neurobiology of Chemical Communication explores the role of the chemical senses in mediating intraspecific communication. Providing an up-to-date outline of the most recent advances in the field, it presents data from laboratory and wild species, ranging from invertebrates to vertebrates, from insects to humans. The book examines the structure, anatomy, electrophysiology, and molecular biology of pheromones. It discusses how chemical signals work on different mammalian and non-mammalian species and includes chapters on insects, Drosophila, honey bees, amphibians, mice, tigers, and cattle. It also explores the controversial topic of human pheromones. An essential reference for students and researchers in the field of pheromones, this is also an ideal resource for those working on behavioral phenotyping of animal models and persons interested in the biology/ecology of wild and domestic species.
