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 Changing Landscapes An Ecological Perspective written by Izaak S. Zonneveld and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Landscape Ecology is an emerging science of gaining momentum over the past few decades in the scientific as well as in the planning-management worlds. Although the field is rooted in biology and geography, the approaches to understanding the ecology of a landscape are highly divers. This hybrid vigor provides power to the field. One can no longer view a local ecosystem or land use in isolation from global areas and time frames. The surrounding landscape mosaic and the flows and movements in a landscape must be considered, especially the linkage between humans requiring resources provided by nature, the constraints on their use as well as the responding landscape.

Download or read book European Wood pastures in Transition written by Tibor Hartel and published by Routledge. This book was released on 2014-06-27 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood-pastures are important elements of European cultural identity and have an exceptional ecological value, yet they are in decline all over Europe. The structure of wood-pastures is strongly influenced by grazing and multiple other land uses and by local and regional environmental conditions. This book examines the diverse expressions of wood-pastures across Europe. It provides a new perspective, using a social-ecological framework to explore social and ecological values, governing institutions, threats and conservation approaches. It explores the major drivers of decline, which are shown to be related to accelerated cultural, institutional and developmental changes occurring across Europe over the past century. Case studies are included from North-Western, Southern, and Eastern Europe. Written by renowned scholars and conservationists, the book contributes to developing better, locally adapted conservation policies and management approaches for wood-pastures.
Download or read book People Plants and Landscapes written by Kristen J. Gremillion and published by University of Alabama Press. This book was released on 1997-01-30 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: People, Plants, and Landscapes showcases the potential of modern paleoethnobotany, an interdisciplinary field that explores the interactions between human beings and plants by examining archaeological evidence. Using different methods and theoretical approaches, the essays in this work apply botanical knowledge to studies of archaeological plant remains and apply paleoethnobotany to nonarchaeological sources of evidence. The resulting techniques often lie beyond the traditional boundaries of either archaeology or botany. With this ground-breaking work, the technically and methodologically enhanced paleoethnobotany of the 1990s has joined forces with ecological and evolutionary theory to forge explanations of changing relationships between human and plant populations.

Download or read book Wildflowers and Plant Communities of the Southern Appalachian Mountains and Piedmont written by Timothy P. Spira and published by Univ of North Carolina Press. This book was released on 2011-05-16 with total page 541 pages. Available in PDF, EPUB and Kindle. Book excerpt: This richly illustrated field guide serves as an introduction to the wildflowers and plant communities of the southern Appalachians and the rolling hills of the adjoining piedmont. Rather than organizing plants, including trees, shrubs, and herbaceous plants, by flower color or family characteristics, as is done in most guidebooks, botanist Tim Spira takes a holistic, ecological approach that enables the reader to identify and learn about plants in their natural communities. This approach, says Spira, better reflects the natural world, as plants, like other organisms, don't live in isolation; they coexist and interact in myriad ways. Full-color photo keys allow the reader to rapidly preview plants found within each of the 21 major plant communities described, and the illustrated species description for each of the 340 featured plants includes fascinating information about the ecology and natural history of each plant in its larger environment. With this new format, readers can see how the mountain and piedmont landscapes form a mosaic of plant communities that harbor particular groups of plants. The volume also includes a glossary, illustrations of plant structures, and descriptions of sites to visit. Whether you're a beginning naturalist or an expert botanist, this guidebook is a useful companion on field excursions and wildflower walks, as well as a valuable reference.

Download or read book The Theory of Ecological Communities MPB 57 written by Mark Vellend and published by Princeton University Press. This book was released on 2020-09-15 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: A plethora of different theories, models, and concepts make up the field of community ecology. Amid this vast body of work, is it possible to build one general theory of ecological communities? What other scientific areas might serve as a guiding framework? As it turns out, the core focus of community ecology—understanding patterns of diversity and composition of biological variants across space and time—is shared by evolutionary biology and its very coherent conceptual framework, population genetics theory. The Theory of Ecological Communities takes this as a starting point to pull together community ecology's various perspectives into a more unified whole. Mark Vellend builds a theory of ecological communities based on four overarching processes: selection among species, drift, dispersal, and speciation. These are analogues of the four central processes in population genetics theory—selection within species, drift, gene flow, and mutation—and together they subsume almost all of the many dozens of more specific models built to describe the dynamics of communities of interacting species. The result is a theory that allows the effects of many low-level processes, such as competition, facilitation, predation, disturbance, stress, succession, colonization, and local extinction to be understood as the underpinnings of high-level processes with widely applicable consequences for ecological communities. Reframing the numerous existing ideas in community ecology, The Theory of Ecological Communities provides a new way for thinking about biological composition and diversity.
Download or read book Plant Conservation written by Alan Hamilton and published by Earthscan. This book was released on 2013 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this, the latest in the People and Plants series, plant conservation is described in the context of livelihoods and development, and ways of balancing the conservation of plant diversity with the use of plants and the environment for human benefit are discussed. A central contention in this book is that local people must be involved if conservation is to be successful. Also examined are ways of prioritizing plants and places for conservation initiatives, approaches to in situ and ex situ conservation, and how to approach problems of unsustainable harvesting of wild plants. Roles for botanists, foresters, sociologists, development workers and others are discussed. This book acts as a unifying text for the series, integrating case studies and methodologies considered in previous volumes and pointing out in a comprehensive, accessible volume the valuable lessons to be learned.
