Download or read book Plant Communication from an Ecological Perspective written by František Baluška and published by Springer Science & Business Media. This book was released on 2010-08-05 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book EVOLUTIONARY ECOLOGY OF ARABIDOPSIS THALIANA written by Adebobola O. Imeh-Nathaniel and published by . This book was released on 2012 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: Previous studies have demonstrated that plants may be affected by their interactions with both biotic and abiotic environmental factors. An important biotic factor that usually affects the performance of plants is insect herbivory. In addition, abiotic factors such as light, or more specifically ultraviolet B (UVB) radiation, can also affect growth and physiological processes in plants. Arabidopsis thaliana is an annual herbaceous plant species with documented defense strategies including resistance and tolerance. Studies have also shown that these plant responses to insect herbivory may be modified by other abiotic factors such as UVB radiation. In a series of common garden experiments, the role of insect herbivory per se and in combination with UVB radiation was evaluated. Using a population of recombinant inbred lines of A. thaliana, the first experiment (described in Chapter 1) investigated the role of plant trichomes and size on patterns of plant use by an insect community. In this experiment, it was also evaluated whether insect herbivory imposes selection on trichome production and plant size. In a second experiment (described in Chapters 2 and 3), the effect of UVB radiation on plant resistance and tolerance to insect herbivory as well as on their potential fitness costs was assessed. This experiment also evaluated the role of UVB on patterns of plant utilization by insect herbivores and whether this important abiotic factor may influence plant phenotypic responses. Results from these experiments revealed that plant trichomes influenced levels of herbivore damage and plant size had an effect on colonization of plants by insect herbivores. In addition, results from selection analyses revealed that insect herbivores exerted directional selection on trichome density in A. thaliana. The second study showed that UVB radiation influenced the expression of resistance and tolerance as well as their associated fitness costs. Similarly, patterns of plant utilization by insect herbivores and phenotypic responses of plants to insect herbivory were modified by UVB radiation. Overall, these results highlight the importance of evaluating complex environments, including both abiotic and biotic factors, as it relates to the evolution and maintenance of traits related to plant defense against insect herbivory.

Available in PDF, EPUB and Kindle. Book excerpt: Plant evolutionary ecology is a rapidly growing discipline which emphasizes that populations adapt and evolve not in isolation, but in relation to other species and abiotic environmental features such as climate. Although it departs from traditional evolutionary and ecological fields of study, the field is connected to branches of ecology, genetics, botany, conservation, and to a number of other fields of applied science, primarily through shared concepts and techniques. However, most books regarding evolutionary ecology focus on animals, creating a substantial need for scholarly literature with an emphasis on plants. Approaches to Plant Evolutionary Ecology is the first book to specifically explore the evolutionary characteristics of plants, filling the aforementioned gap in the literature on evolutionary ecology. Renowned plant ecologist Gregory P. Cheplick summarizes and synthesizes much of the primary literature regarding evolutionary ecology, providing a historical context for the study of plant populations from an evolutionary perspective. The book also provides summaries of both traditional (common gardens, reciprocal transplants) and modern (molecular genetic) approaches used to address questions about plant adaptation to a diverse group of abiotic and biotic factors. Cheplick provides a rigorously-written introduction to the rapidly growing field of plant evolutionary ecology that will appeal to undergraduate and graduate students with an interest in ecology and evolution, as well as educators who are teaching courses on related topics.

Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the interactive effects of environmental stresses with plant and ecosystem functions, especially with respect to changes in the abundance of carbon dioxide. The interaction of stresses with elevated carbon dioxide are presented from the cellular through whole plant ecosystem level. The book carefully considers not only the responses of the above-ground portion of the plant, but also emphasizes the critical role of below-ground (rhizosphere) components (e.g., roots, microbes, soil) in determining the nature and magnitude of these interactions.* Will rising CO2 alter the importance of environmental stress in natural and agricultural ecosystems?* Will environmental stress on plants reduce their capacity to remove CO2 from the atmosphere?* Are some stresses more important than others as we concern ourselves with global change?* Can we develop predictive models useful for scientists and policy-makers?* Where should future research efforts be focused?

Available in PDF, EPUB and Kindle. Book excerpt: Tremendous progress has been made during the past decade in the burgeoning field of plant reproductive biology. A number of quantitative and technical breakthroughs, such as horizontal starch-gel electrophoresis, have resulted in a revolution in our thinking. The study of breeding systems, which used to be marked by a rather static focus on pollination and self-incompatibility, has been transformed by dynamic models of transitional pathways, and investigators are looking not only into genetic factors but ecological ones as well. Workers in the field have recently produced detailed accounts of mating success and the relative fitness of plants as male and female parents, thus testing the applicability of sexual selection theory to plants. Ecology and Evolution of Plant Reproduction surveys recent advances in the field of plant reproductive biology and identifies fruitful avenues for future research. The contributors are well known in the fields of morphology, systematics, genetics, cell biology, and ecology, representing the full spectrum of approaches that contribute vigor to this emerging field. This new work will benefit professionals and graduate students in plant science and plant breeding, evolutionary ecology, genetics, and reproductive biology.

Download or read book Plant Competition in a Changing World written by Judy Simon and published by Frontiers Media SA. This book was released on 2017-06-22 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Competitiveness describes a key ability important for plants to grow and survive abiotic and biotic stresses. Under optimal, but particularly under non-optimal conditions, plants compete for resources including nutrients, light, water, space, pollinators and other. Competition occurs above- and belowground. In resource-poor habitats, competition is generally considered to be more pronounced than in resource-rich habitats. Although competition occurs between different players within an ecosystem such as between plants and soil microorganisms, our topic focusses on plant-plant interactions and includes inter-specific competition between different species of similar and different life forms and intra-specific competition. Strategies for securing resources via spatial or temporal separation and different resource needs generally reduce competition. Increasingly important is the effect of invasive plants and subsequent decline in biodiversity and ecosystem function. Current knowledge and future climate predictions suggest that in some situations competition will be intensified with occurrence of increased abiotic (e.g. water and nutrient limitations) and biotic stresses (e.g. mass outbreak of insects), but competition might also decrease in situations where plant productivity and survival declines (e.g. habitats with degraded soils). Changing interactions, climate change and biological invasions place new challenges on ecosystems. Understanding processes and mechanisms that underlie the interactions between plants and environmental factors will aid predictions and intervention. There is much need to develop strategies to secure ecosystem services via primary productivity and to prevent the continued loss of biodiversity. This Research Topic provides an up-to-date account of knowledge on plant-plant interactions with a focus on identifying the mechanisms underpinning competitive ability. The Research Topic aims to showcase knowledge that links ecological relevance with physiological processes to better understanding plant and ecosystem function.

Available in PDF, EPUB and Kindle. Book excerpt: Biological diversity, the variety of living organisms on Earth, is traditionally viewed as the diversity of taxa, and species in particular. However, other facets of diversity also need to be considered for a comprehensive understanding of evolutionary and ecological processes. This novel book demonstrates the advantages of adopting a functional approach to diversity in order to improve our understanding of the functioning of ecological systems and theircomponents. The focus is on plants, which are major components of these systems, and for which the functional approach has led to major scientific advances over the last 20 years. PlantFunctional Diversity presents the rationale for a trait-based approach to functional diversity in the context of comparative plant ecology and agroecology. It demonstrates how this approach can be used to address a number of highly debated questions in plant ecology pertaining to plant responses to their environment, controls on plant community structure, ecosystem properties, and the services these deliver to human societies. This research level text will be of particular relevance and use tograduate students and professional researchers in plant ecology, agricultural sciences and conservation biology.

Book excerpt: In Alien Species and Evolution, biologist George W. Cox reviews and synthesizes emerging information on the evolutionary changes that occur in plants, animals, and microbial organisms when they colonize new geographical areas, and on the evolutionary responses of the native species with which alien species interact. The book is broad in scope, exploring information across a wide variety of taxonomic groups, trophic levels, and geographic areas. It examines theoretical topics related to rapid evolutionary change and supports the emerging concept that species introduced to new physical and biotic environments are particularly prone to rapid evolution. The author draws on examples from all parts of the world and all major ecosystem types, and the variety of examples used gives considerable insight into the patterns of evolution that are likely to result from the massive introduction of species to new geographic regions that is currently occurring around the globe. Alien Species and Evolution is the only state-of-the-art review and synthesis available of this critically important topic, and is an essential work for anyone concerned with the new science of invasion biology or the threats posed by invasive species.

Available in PDF, EPUB and Kindle. Book excerpt: In the course of evolution, a great variety of root systems have learned to overcome the many physical, biochemical and biological problems brought about by soil. This development has made them a fascinating object of scientific study. This volume gives an overview of how roots have adapted to the soil environment and which roles they play in the soil ecosystem. The text describes the form and function of roots, their temporal and spatial distribution, and their turnover rate in various ecosystems. Subsequently, a physiological background is provided for basic functions, such as carbon acquisition, water and solute movement, and for their responses to three major abiotic stresses, i.e. hard soil structure, drought and flooding. The volume concludes with the interactions of roots with other organisms of the complex soil ecosystem, including symbiosis, competition, and the function of roots as a food source.

Available in PDF, EPUB and Kindle. Book excerpt: One of the ways to make consistent progress in a particular field of biology consists in choosing a good model system on which to focus the experimental efforts of the scientific community. It has taken a long time for scientists interested in various aspects of the life of plants to reach some sort of consensus. With the advent and impact of molecular biology, the small weed Arabidopsis is now the object of rapidly growing scientific attention. Since it is reasonable to assume that the general molecular mechanisms that are responsible for the physiological, cellular and biochemical properties of plants will be essentially conserved in all plants, it follows that these mechanisms should also operate in Arabidopsis and hence that its genome should contain most of the genes that we need to know about if we want to understand the genetic determination of the life processes in plants.Arabidopsis has a small genome and well documented genetic studies are available. It is easy to grow in large numbers and mutants defining important genetically controlled mechanisms are either available, or can readily be obtained. Various methods to introduce and express isolated homologous or heterologous genes are available. It is therefore realistic and desirable to aim at exploring the genome of this plant in very great detail. As will be illustrated in this book all the elements for such a grand strategy are in place.More and more scientists are therefore willing to accept the obvious and very real practical disadvantages resulting from its small size when experiments call for the isolation of proteins, membranes, subcellular fractions etc, in order to benefit from its extraordinary experimental advantages as a model system in molecular genetics. One can safely predict that in the next decade studies with Arabidopsis will provide major breakthroughs in our understanding of most aspects of plant physiology and developmental biology. The importance of this knowledge for plant breeding and therefore for a sustainable highly productive agriculture cannot be overestimated. We therefore expect that this book will provide valuable guidelines to all those who are planning experiments aimed at understanding various aspects of plant growth, productivity and interactions with the environment. The book offers a wealth of methodical and theoretical information as well as valuable references. It should be of use to students, teachers, as well as advanced researchers and those breeders who want to use molecular techniques in breeding.

This book was released on 2019-04-05 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coral reef declines have been recorded for all major tropical ocean basins since the 1980s, averaging approximately 30-50% reductions in reef cover globally. These losses are a result of numerous problems, including habitat destruction, pollution, overfishing, disease, and climate change. Greenhouse gas emissions and the associated increases in ocean temperature and carbon dioxide (CO2) concentrations have been implicated in increased reports of coral bleaching, disease outbreaks, and ocean acidification (OA). For the hundreds of millions of people who depend on reefs for food or livelihoods, the thousands of communities that depend on reefs for wave protection, the people whose cultural practices are tied to reef resources, and the many economies that depend on reefs for fisheries or tourism, the health and maintenance of this major global ecosystem is crucial. A growing body of research on coral physiology, ecology, molecular biology, and responses to stress has revealed potential tools to increase coral resilience. Some of this knowledge is poised to provide practical interventions in the short-term, whereas other discoveries are poised to facilitate research that may later open the doors to additional interventions. A Research Review of Interventions to Increase the Persistence and Resilience of Coral Reefs reviews the state of science on genetic, ecological, and environmental interventions meant to enhance the persistence and resilience of coral reefs. The complex nature of corals and their associated microbiome lends itself to a wide range of possible approaches. This first report provides a summary of currently available information on the range of interventions present in the scientific literature and provides a basis for the forthcoming final report.

Download or read book Evolutionary Ecology of Plant-Herbivore Interaction written by Juan Núñez-Farfán and published by Springer Nature. This book was released on 2020-07-30 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant-herbivore interactions are a central topic in evolutionary ecology. Historically, their study has been a cornerstone for coevolutionary theory. Starting from classic ecological studies at the phenotypic level, it has since expanded to molecular and genomic approaches. After a historical perspective, the book’s subsequent chapters cover a wide range of topics: from populations to ecosystems; plant- and herbivore-focused studies; in natural and in man-modified ecosystems; and both micro- and macro-evolutionary levels. All chapters include valuable background information and empirical evidence. Given its scope, the book will be of interest to both students and researchers, and will hopefully stimulate further research in this exciting field of evolutionary biology.
