Book Description
"The maturation of ecosystems can be associated with increased connectedness and destabilizing feedbacks from biogenic habitat modification. Over regional scales, resulting disturbances can translate into strong spatial fluxes of ecosystem resources. Using a mechanistic meta-ecosystem model of rocky shore mussel beds, I explore the implications of ecosystem engineering for spatial synchrony and regional matter circulation. At the local scale, I find that aggregated mussel recruitment and feedback from biodeposition and sedimentation can lead to rare and catastrophic fluctuations of population abundance and strong spatial fluxes of (in)organic matter. At the regional scale, I show that resulting dynamics can maintain spatial heterogeneity under strong biotic and abiotic regional connectivity. This is characterized by non-stationary time series and a modulation of spatial synchrony. By explicitly considering stocks and fluxes of engineered matter, I show that biogenic habitat modification interacts with spatial synchrony to determine the turnover and spatial distribution of (in)organic matter. These results suggest that resolving the implications of regional connectivity for population persistence, habitat structure, and resources availability requires considering how ecosystem engineering interacts with the stability and the connectivity of natural systems." --

Book Description
This book presents current meta-ecosystem models and their derivation from classical ecosystem and metapopulation theories. Specifically, it reviews recent modelling efforts that have emphasized the role of nonlinear dynamics on spatial and food web networks, and which have cast their implications within the context of spatial synchrony and ecological stoichiometry. It suggests that these recent advances naturally lead to a generalization of meta-ecosystem theories to spatial fluxes of matter that have both a trophic and non-trophic impact on species. Ecosystem dynamics refers to the cycling of matter and energy across ecological compartments through processes such as consumption and recycling. Spatial dynamics established its ecological roots with metapopulation theories and focuses on scaling up local ecological processes through the limited movement of individuals and matter. Over the last 15 years, theories integrating ecosystem and spatial dynamics have quickly coalesced into meta-ecosystem theories, the focus of this book. The book will be of interest to graduate students and researchers who wish to learn more about the synthesis of ecosystem and spatial dynamics, which form the foundation of the theory of meta-ecosystems.

Book Description
The contributors to this volume propose strategies of urgent and vital importance that aim to make today’s urban environments more resilient. Resilience, the ability of complex systems to adapt to changing conditions, is a key frontier in ecological research and is especially relevant in creative urban design, as urban areas exemplify complex systems. With something approaching half of the world’s population now residing in coastal urban zones, many of which are vulnerable both to floods originating inland and rising sea levels, making urban areas more robust in the face of environmental threats must be a policy ambition of the highest priority. The complexity of urban areas results from their spatial heterogeneity, their intertwined material and energy fluxes, and the integration of social and natural processes. All of these features can be altered by intentional planning and design. The complex, integrated suite of urban structures and processes together affect the adaptive resilience of urban systems, but also presupposes that planners can intervene in positive ways. As examples accumulate of linkage between sustainability and building/landscape design, such as the Shanghai Chemical Industrial Park and Toronto’s Lower Don River area, this book unites the ideas, data, and insights of ecologists and related scientists with those of urban designers. It aims to integrate a formerly atomized dialog to help both disciplines promote urban resilience.

Book Description
This book is open access under a CC BY-NC 2.5 license. This book provides an unprecedented synthesis of the current status of scientific and management knowledge regarding global rangelands and the major challenges that confront them. It has been organized around three major themes. The first summarizes the conceptual advances that have occurred in the rangeland profession. The second addresses the implications of these conceptual advances to management and policy. The third assesses several major challenges confronting global rangelands in the 21st century. This book will compliment applied range management textbooks by describing the conceptual foundation on which the rangeland profession is based. It has been written to be accessible to a broad audience, including ecosystem managers, educators, students and policy makers. The content is founded on the collective experience, knowledge and commitment of 80 authors who have worked in rangelands throughout the world. Their collective contributions indicate that a more comprehensive framework is necessary to address the complex challenges confronting global rangelands. Rangelands represent adaptive social-ecological systems, in which societal values, organizations and capacities are of equal importance to, and interact with, those of ecological processes. A more comprehensive framework for rangeland systems may enable management agencies, and educational, research and policy making organizations to more effectively assess complex problems and develop appropriate solutions.

Book Description
Around the World, metal pollution is a major problem. Conventional practices of toxic metal removal can be ineffective and/or expensive, delaying and exacerbating the crisis. Those communities dealing with contamination must be aware of the fundamentals advances of microbe-mediated metal removal practices because these methods can be easily used and require less remedial intervention. This book describes innovations and efficient applications for metal bioremediation for environments polluted by metal contaminates.

Book Description
The exponentially increasing amounts of biological data along with comparable advances in computing power are making possible the construction of quantitative, predictive biological systems models. This development could revolutionize those biology-based fields of science. To assist this transformation, the U.S. Department of Energy asked the National Research Council to recommend mathematical research activities to enable more effective use of the large amounts of existing genomic information and the structural and functional genomic information being created. The resulting study is a broad, scientifically based view of the opportunities lying at the mathematical science and biology interface. The book provides a review of past successes, an examination of opportunities at the various levels of biological systemsâ€" from molecules to ecosystemsâ€"an analysis of cross-cutting themes, and a set of recommendations to advance the mathematics-biology connection that are applicable to all agencies funding research in this area.

Book Description
This book analyzes the theory of ecological engineering of human settlements and provides case studies on the improvement of degraded lands and vegetation restoration, especially focusing on saline-alkali land, abandoned land, water source areas, and the impact of green belts on noise and air quality on the highways. In addition, it discusses the issue of biodiversity conservation strategies in rural landscape construction and demonstrates experiment measurement and field survey methods. The results obtained are supplemented by numerical calculations, presented in the form of tables and figures. As the first monograph on this subject, the book provides a wealth of ideas and resources for researchers, professionals and practitioners in the field of human settlements.
