Book Description
Food Chains and Webs explains that feeding relationships are at the heart of life on Earth. It looks at the different types of living thing in a food web - from producer to top consumer - as well as food pyramids and topics like bioaccumulation. It tackles common confusions about the science and shows how topics are relevant to the reader.

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
Often the meanings of words are changed subtly for interesting reasons. The implication of the word 'community' has changed from including all the organisms in an area to only those species at a particular trophic level (and often a taxonomically restricted group), for example, 'bird-community'. If this observation is correct, its probable cause is the dramatic growth in our knowledge of the ecological patterns along trophic levels (I call these horizontal patterns) and the processes that generate them. This book deals with vertical patterns - those across trophic levels -and tries to compensate for their relative neglect. In cataloging a dozen vertical patterns I hope to convince the reader that species interactions across trophic levels are as patterned as those along trophic levels and demand explanations equally forcefully. But this is not the only objective. A limited number of processes shape the patterns of species interaction; to demonstrate their existence is an essential step in understanding why ecosystems are the way they are. To achieve these aims I must resort to both mathematical techniques to develop theories and statistical techniques to decide between rival hypotheses. The level of mathematics is likely to offend nearly everyone. Some will find any mathematics too much, while others will consider the material to be old, familiar ground and probably explained with a poor regard for rigour and generality.

Book Description
Children will enjoy exploring the vast prairies of North America in Prairie Food Chains. Young readers will learn about the different types of prairie habitats, how animals get the nutrients they need, and the fascinating adaptation some prairie animals undergo to survive in their habitats.

Book Description
Explains the predator-prey relationships that all living things are a part of, represented by the food chains and food webs in a variety of habitats, how everything is connected, and how every living organism plays a role.

Book Description
"This book explores the food chains and webs that exist in a mountain habitat. It equips readers with crucial vocabulary, using examples from that habitat to explain the roles of producers, consumers and decomposers, and illustrates how living things depend upon each other. Readers learn how fragile food chains can be, how they can be broken, and what we can do to prevent this."--
