Book Description
Dynamic Food Webs challenges us to rethink what factors may determine ecological and evolutionary pathways of food web development. It touches upon the intriguing idea that trophic interactions drive patterns and dynamics at different levels of biological organization: dynamics in species composition, dynamics in population life-history parameters and abundances, and dynamics in individual growth, size and behavior. These dynamics are shown to be strongly interrelated governing food web structure and stability and the role of populations and communities play in ecosystem functioning. Dynamic Food Webs not only offers over 100 illustrations, but also contains 8 riveting sections devoted to an understanding of how to manage the effects of environmental change, the protection of biological diversity and the sustainable use of natural resources. Dynamic Food Webs is a volume in the Theoretical Ecology series. Relates dynamics on different levels of biological organization: individuals, populations, and communities Deals with empirical and theoretical approaches Discusses the role of community food webs in ecosystem functioning Proposes methods to assess the effects of environmental change on the structure of biological communities and ecosystem functioning Offers an analyses of the relationship between complexity and stability in food webs

Book Description
Reflecting the recent surge of activity in food web research fueled by new empirical data, this authoritative volume successfully spans and integrates the areas of theory, basic empirical research, applications, and resource problems. Written by recognized leaders from various branches of ecological research, this work provides an in-depth treatment of the most recent advances in the field and examines the complexity and variability of food webs through reviews, new research, and syntheses of the major issues in food web research. Food Webs features material on the role of nutrients, detritus and microbes in food webs, indirect effects in food webs, the interaction of productivity and consumption, linking cause and effect in food webs, temporal and spatial scales of food web dynamics, applications of food webs to pest management, fisheries, and ecosystem stress. Three comprehensive chapters synthesize important information on the role of indirect effects, productivity and consumer regulation, and temporal, spatial and life history influences on food webs. In addition, numerous tables, figures, and mathematical equations found nowhere else in related literature are presented in this outstanding work. Food Webs offers researchers and graduate students in various branches of ecology an extensive examination of the subject. Ecologists interested in food webs or community ecology will also find this book an invaluable tool for understanding the current state of knowledge of food web research.

Book Description
Concepts of Biology is designed for the single-semester introduction to biology course for non-science majors, which for many students is their only college-level science course. As such, this course represents an important opportunity for students to develop the necessary knowledge, tools, and skills to make informed decisions as they continue with their lives. Rather than being mired down with facts and vocabulary, the typical non-science major student needs information presented in a way that is easy to read and understand. Even more importantly, the content should be meaningful. Students do much better when they understand why biology is relevant to their everyday lives. For these reasons, Concepts of Biology is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand.We also strive to show the interconnectedness of topics within this extremely broad discipline. In order to meet the needs of today's instructors and students, we maintain the overall organization and coverage found in most syllabi for this course. A strength of Concepts of Biology is that instructors can customize the book, adapting it to the approach that works best in their classroom. Concepts of Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand--and apply--key concepts.

Book Description
Unarguably, preserving the ecosystem, securing sustainability and understanding the dynamics of agro-food chains have all become vital policy objectives with several interlinked dimensions. The main objectives of this book are to draw the attention of researchers, policymakers and businesspeople to the relation between agro-food chains and the ecosystem, and to demonstrate the importance of building resilient agro-food chains that take into account climate change and environmental challenges. Agro-food chains as they function today can serve as powerful tools for promoting sustainable forms of agriculture, consumption and production that are embedded in a viable ecosystem. The book addresses a range of environmental, methodological and societal issues from a transaction perspective, while also providing extensive background information on the topic, and outlining future applications and research directions.

Book Description
Food webs describe the structure of communities and their energy flows, and they represent interactions between species in ecosystems. Recently, we have witnessed rapid development of techniques for both experimental studies and theoretical/computational studies on food webs as well as species interactions. This reprint book is focused on food chains and food webs in aquatic ecosystems, with seven papers published in the corresponding Special Issue of Applied Sciences. The topics include empirical studies on food chains and food webs as well as effects of environmental factors on organisms in aquatic ecosystems.

Book Description
How do animals interact within an ecosystem? What is an animal’s role within their food chain? This life science guide introduces readers to familiar and exotic producers, consumers, and decomposers to give them a well-rounded look at the flow of energy through the food chain. This important life science concept is illustrated by color photographs of each animal, and fascinating facts about their place in their ecosystem.
