Available in PDF, EPUB and Kindle. Book excerpt: As one of the most quantitative of ecological subdisciplines, resource competition is an important, central area of ecology. Recently research into this area has increased dramatically and resource competition models have become more complex. The characterisation of this phenomenon is therefore the aim of this book. Resource Competition seeks to identify the unifying principles emerging from experimental and theoretical approaches as well as the differences between organisms, illustrating that greater knowledge of resource competition will benefit human and environmental welfare. This book will serve as an indispensable guide to ecologists, evolutionary biologists and environmental managers, and all those interested in resource competition as an emerging discipline.

This book was released on 2020-03-31 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the central questions of ecology is why there are so many different kinds of plants and animals. Here David Tilman presents a theory of how organisms compete for resources and the way their competition promotes diversity. Developing Hutchinson's suggestion that the main cause of diversity is the feeding relations of species, this book builds a mechanistic, resource-based explanation of the structure and functioning of ecological communities. In a detailed analysis of the Park Grass Experiments at the Rothamsted Experimental Station in England, the author demonstrates that the dramatic results of these 120 years of experimentation are consistent with his theory, as are observations in many other natural communities. The consumer-resource approach of this book is applicable to both animal and plant communities, but the majority of Professor Tilman's discussion concentrates on the structure of plant communities. All theoretical arguments are developed graphically, and formal mathematics is kept to a minimum. The final chapters of the book provide some testable speculations about resources and animal communities and explore such problems as the evolution of "super species," the differences between plant and animal community diversity patterns, and the cause of plant succession.

Available in PDF, EPUB and Kindle. Book excerpt: Hunt convincingly demonstrates that competition is not about dividing up limited resources but about creating more resources and thus competition is pro-society. This truly interdisciplinary book successfully develops a general theory of competition which is rich in explanatory breadth and depth. Consequently, executives and entrepreneuers, management consultants, public makers, and scholars and students in economics, law, political science, and business should read and study this book. —Robert F. Lusch, University of Oklahoma This book develops a new theory of competition. This theory – labeled "resource-advantage theory" – stems from no single research tradition, but draws on several different traditions in economics, management, marketing, and sociology. In this ground-breaking volume, Shelby Hunt articulates R-A theory, uses the theory to explain and predict economic phenomena, and shows how (and why) it explains and predicts such phenomena.

This book was released on 1996-10-31 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rory Putman addresses the question of how, in many temporate ecosystems, diverse and species-rich assemblies of ungulates manage to co-exist despite often quite extensive overlap in ecological requirements. Putman explores the potential for competition, competition tolerance and even positive facilitation amongst the members of such guilds of ungulates. As a central worked example, the author employs data resulting from over 20 years of personal research into the ecology and population dynamics of various large herbivores of the New Forest in Southern England. With these, he applies formal protocols in resource use, evidence for resource limitation and evidence for interaction between species in changing population size over the years.

Available in PDF, EPUB and Kindle. Book excerpt: The question "Why are there so many species?" has puzzled ecologist for a long time. Initially, an academic question, it has gained practical interest by the recent awareness of global biodiversity loss. Species diversity in local ecosystems has always been discussed in relation to the problem of competi tive exclusion and the apparent contradiction between the competitive exclu sion principle and the overwhelming richness of species found in nature. Competition as a mechanism structuring ecological communities has never been uncontroversial. Not only its importance but even its existence have been debated. On the one extreme, some ecologists have taken competi tion for granted and have used it as an explanation by default if the distribu tion of a species was more restricted than could be explained by physiology and dispersal history. For decades, competition has been a core mechanism behind popular concepts like ecological niche, succession, limiting similarity, and character displacement, among others. For some, competition has almost become synonymous with the Darwinian "struggle for existence", although simple plausibility should tell us that organisms have to struggle against much more than competitors, e.g. predators, parasites, pathogens, and envi ronmental harshness.

Book excerpt: The identification of inputs and outputs is the first and probably most important step in testing and analyzing complex systems. Following accepted natural laws such as the conservation of mass and the principle of electroneutrality, the input/output analysis of the system, be it steady or in connection with perturbations will reveal the status dynamic, will identify whether changes are reversible or irreversible and whether changing the input will cause a hysteresis response. Moreover, measurements ofinput and output fluxes can indicate the storage capacity ofa system, its resilience to buffer or amplify variations of the external input, and it can identify structural changes. Therefore, to a certain extent, the input/output analysis can facilitate predictions about the ecosystem stability. The measurement of fluxes and the determination of inputs and outputs of eco systems are, in many aspects, analogous to measurements done by engineers when testing an electronic apparatus. The first step is the measurement ofthe input/output properties of the instrument as a whole, or ofvarious circuit boards, and the compari· son ofthese with the expected variations of the original design. Varying input and out· put can give valuable information about the stability and the regulatory properties of the device. Nevertheless, only the circuit as an entity has specific properties which cannot be anticipated if the individual components are investigated regardless oftheir position. Also, the instrument as a whole will have different input/output properties than its subcircuits.

Available in PDF, EPUB and Kindle. Book excerpt: Dramatic changes are taking place in the world of international business as we move forward in the twenty first century. Increasing levels of international trade and foreign direct investment, the growth of huge multinational corporations, and the emergence of new centres of economic prosperity are all evident. Businesses are faced with the challenge of having to survive and succeed in this competitive environment. This book looks specifically at the question of how firms attain a sustainable competitive advantage (SCA) in a global environment characterised by above average levels of geographic scope, marketing convergence and cross-national interdependencies. This work will be of essential interest to academics and researchers in the fields of international strategy and international business.

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: Perspectives on Plant Competition is mainly about addressing the many different perspectives in plant competition and finding a common ground among them. Its aim is that through this common ground, new theories can be created. Encompassing 20 chapters, this book is divided into three parts. Part I, Perspectives on the Determinants of Competitive Success, consists of eight chapters. This section deals mainly on the question of determination of competitive success. Different writers put forward various definitions of competition and competitive success to shed light on the question at hand. In the second part of this book, an opposing set of views regarding the consequences of competitive interactions for the plant community structure is provided. This section emphasizes the idea that competition is not the sole force in natural communities. Each chapter in this part focuses on a certain aspect of competition as seen in different communities – across and within habitats – and systems. Part III, which comprises of four chapters, focuses on the competition within the context of interaction of plants with organisms on the other trophic levels. The chapters set forth the idea that competition depends on the impacts of herbivores, parasites, and symbionts. The concluding part of the book greatly emphasizes the need to integrate the mechanisms of competition into the framework of the entire food web.

Available in PDF, EPUB and Kindle. Book excerpt: Competition is one of the most important factors controlling the distribution and abundance of living creatures. Sperm cells racing up reproductive tracts, beetle larvae battling inside single seeds, birds defending territories, and trees interfering with the light available to neighbours, are all engaged in competition for limited resources. Along with predation and mutualism, competition is one of the three major biological forces that assemble living communities. Recent experimental work, much of it only from the last few decades, has enhanced human knowledge of the prevalence of competition in nature. There are acacia trees that use ants to damage vines, beetles that compete in arenas for access to dung balls, tadpoles that apparently poison their neighbours, birds that smash the eggs of potential competitors, and plants that associate with fungi in order to increase access to soil resources. While intended as an up-to-date reference work on the state of this branch of ecology, the many non-technical examples will make interesting reading for those with a general interest in nature. Greatly expanded from the first prize-winning edition, there are entirely new chapters, including one on resources and another on competition gradients in nature. The author freely ranges across all major taxonomic groups in search of evidence. The question of whether competition occurs is no longer useful, the author maintains; rather the challenge is to determine when and where each kind of competition is important in natural systems. For this reason, variants of competition such as intensity, asymmetry and hierarchies are singled out for particular attention. The book concludes with the difficulties of finding general principles in complex ecological communities, and illustrates the limitations on knowledge that arise out of the biased conduct of scientists themselves. Competition can be found elsewhere in living systems other than ecological communities, at sub-microscopic scales in the interactions of enzymes and neural pathways, and over large geographic areas in the spread of human populations and contrasting ideas about the world. Human societies are therefore also examined for evidence of the kinds of competition found among other living organisms. Using an array of historical examples, including Biblical conflicts, the use of noblemen's sons in the Crusades, the Viking raids in Europe, strategic bombing campaigns in the Second World War, and ethnic battles of the Balkans, the book illustrates how most of the aspects of competition illustrated with plants and animals can be extended to the interactions of human beings and their societies.

Available in PDF, EPUB and Kindle. Book excerpt: Antelopes constitute a fundamental part of ecosystems throughout Africa and Asia where they act as habitat architects, dispersers of seeds, and prey for large carnivores. The fascication they hold in the human mind is evident from prehistoric rock paintings and ancient Egyptian art to today's wildlife documentaries and popularity in zoos. In recent years, however, the spectacular herds of the past have been decimated or extripated over wide areas in the wilds, and urgent conservation action is needed to preserve this world heritage for generations to come. As the first book dedicated to antelope conservation, this volume sets out to diagnose the causes of the drastic declines in antelope biodiversity and on this basis identify the most effective points of action. In doing so, the book covers central issues in the current conservation debate, especially related to the management of overexploitation, habitat fragmentation, disease transmission, climate change, populations genetics, and reintroductions. The contributions are authored by world-leading experts in the field, and the book is a useful resource to conservation scientists and practitioners, researchers, and students in related disciplines as well as interested lay people.

Book excerpt: This book describes how competition between plant species, and succession in plant ecosystems, operate in grasslands and grazed pastures, both natural and sown. It discusses how competition both affects botanical structure, productivity and persistence of pastures and is itself regulated by biological, environmental and management factors, such as grazing animals. The book also examines the ways in which competition and succession are analysed, evaluated and measured, and brings to the agricultural arena the considerable progress made in understanding the principles of competition from theoretical and experimental ecology.

Available in PDF, EPUB and Kindle. Book excerpt: Among scholars who focus on the politics of natural resources, conventional wisdom asserts that resource-scarce states have the strongest interest in securing control over resources. Counterintuitively, however, in Perils of Plenty, Jonathan N. Markowitz finds that the opposite is true. In actuality, what states make influences what they want to take. Specifically, Markowitz argues that the more economically dependent states are on resource extraction rents for income, the stronger their preferences will be to secure control over resources. He tests the theory with a set of case studies that analyze how states reacted to the 2007 exogenous climate shock that exposed energy resources in the Arctic. Given the dangerous potential for conflict escalation in the Middle East and the South China Sea and the continued shrinkage of the polar ice cap, this book speaks to a genuinely important development in world politics that will have implications for understanding the political effects of climate change for many years to come.
