Book Description
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 Description
A comprehensive framework for understanding species coexistence Coexistence is the central concept in community ecology, but an understanding of this concept requires that we study the actual mechanisms of species interactions. Coexistence in Ecology examines the major features of these mechanisms for species that coexist at different positions in complex food webs, and derives empirical tests from model predictions. Exploring the various challenges species face, Mark McPeek systematically builds a model food web, beginning with an ecosystem devoid of life and then adding one species at a time. With the introduction of each new species, he evaluates the properties it must possess to invade a community and quantifies the changes in the abundances of other species that result from a successful invasion. McPeek continues this process until he achieves a multitrophic level food web with many species coexisting at each trophic level, from omnivores, mutualists, and pathogens to herbivores, carnivores, and basic plants. He then describes the observational and experimental empirical studies that can test the theoretical predictions resulting from the model analyses. Synthesizing decades of theoretical research in community ecology, Coexistence in Ecology offers new perspectives on how to develop an empirical program of study rooted in the natural histories of species and the mechanisms by which they actually interact with one another.

Book Description
Evolution of Primary Producers in the Sea reference examines how photosynthesis evolved on Earth and how phytoplankton evolved through time – ultimately to permit the evolution of complex life, including human beings. The first of its kind, this book provides thorough coverage of key topics, with contributions by leading experts in biophysics, evolutionary biology, micropaleontology, marine ecology, and biogeochemistry.This exciting new book is of interest not only to students and researchers in marine science, but also to evolutionary biologists and ecologists interested in understanding the origins and diversification of life. Evolution of Primary Producers in the Sea offers these students and researchers an understanding of the molecular evolution, phylogeny, fossil record, and environmental processes that collectively permits us to comprehend the rise of phytoplankton and their impact on Earth's ecology and biogeochemistry. It is certain to become the first and best word on this exhilarating topic. - Discusses the evolution of phytoplankton in the world's oceans as the first living organisms and the first and basic producers in the earths food chain - Includes the latest developments in the evolution and ecology of marine phytoplankton specifically with additional information on marine ecosystems and biogeochemical cycles - The only book to consider of the evolution of phytoplankton and its role in molecular evolution, biogeochemistry, paleontology, and oceanographic aspects - Written at a level suitable for related reading use in courses on the Evolution of the Biosphere, Ecological and Biological oceanography and marine biology, and Biodiversity

Book Description
The Freshwaters of Patagonia adopts a socioecological approach, in which experts from across Patagonia review recent, scientifically rigorous literature and data of their own, thus synthesizing the current knowledge directly relevant to understand the present state and future trends of icefields, freshwater and wetland ecosystems in this region. The book’s organization into three parts provides a studied and comprehensive view on the patterns and processes of the various ecosystems in Patagonia, and describes the sociological aspects of freshwater ecosystems, as well as characterizes the conservation of the freshwater and wetland ecosystems, in Patagonia. The chapters offer a broad, state-of-the-art overview of the current status of glaciers, freshwater and wetland ecosystems of this region, as well as studies of both local and large scale biodiversity patterns, and study cases of extreme and naturally polluted environments.The volume concludes with the current status of Patagonian freshwaters, and discusses the scientific, legal and administrative tools aimed at their sustainable management within the framework of the UNEP Sustainable Development Goals 2030 Agenda. A broad audience of students, scientists, engineers, environmental managers, and policy makers will be interested in this volume.

Book Description
Competition between species arises when two or more species share at least some of the same limited resources. It is likely to affect all species, as well as many higher-level aspects of community and ecosystem dynamics. Interspecific competition shares many of the same features as density dependence (intraspecific competition) and evolution (competition between genotypes). In spite of this, a robust theoretical framework is not yet in place to develop a more coherent understanding of this important interaction. Despite its prominence in the ecological literature, the theory seems to have lost direction in recent decades, with many synthetic papers promoting outdated ideas, failing to use resource-based models, and having little utility in applied fields such as conservation and environmental management. Competition theory has done little to incorporate new findings regarding consumer-resource interactions in the context of larger food webs containing behaviourally or evolutionarily adapting components. Overly simple models and methods of analysis continue to be influential. Competition Theory in Ecology represents a timely opportunity to address these shortcomings and suggests a more useful approach to modelling that can provide a basis for future models that have greater predictive ability in both ecology and evolution. The book concludes with some broader observations on the lack of agreement on general principles to use in constructing mathematical models to help understand ecological systems. It argues that a more open discussion and debate of the underlying structure of ecological theory is now urgently required to move the field forward.
