Ocean Food Webs


Book Description

The ocean is full of complex food webs made up of many different animals fighting to stay alive within this massive ecosystem. Carnivores, herbivores, and other classified creatures are introduced within the accessible and age-appropriate narrative, which is presented in a conversational tone and creative way. Popular creatures are categorized separately and given detailed descriptions, which allows readers to expand their knowledge of each animal. Helpful graphic organizers provide additional information. Full-color photographs make this an exciting learning experience for all those interested in expanding their knowledge of the science and webs of marine life.




Intermittent Rivers and Ephemeral Streams


Book Description

Intermittent Rivers and Ephemeral Streams: Ecology and Management takes an internationally broad approach, seeking to compare and contrast findings across multiple continents, climates, flow regimes, and land uses to provide a complete and integrated perspective on the ecology of these ecosystems. Coupled with this, users will find a discussion of management approaches applicable in different regions that are illustrated with relevant case studies. In a readable and technically accurate style, the book utilizes logically framed chapters authored by experts in the field, allowing managers and policymakers to readily grasp ecological concepts and their application to specific situations. - Provides up-to-date reviews of research findings and management strategies using international examples - Explores themes and parallels across diverse sub-disciplines in ecology and water resource management utilizing a multidisciplinary and integrative approach - Reveals the relevance of this scientific understanding to managers and policymakers




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.




River Food Chains


Book Description

"This book explores the food chains and webs that exist in river habitats. 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."--

A Nile River Food Chain


Book Description

Welcome to the Nile River in Egypt! As you slosh through the river bank and puddle-jump the marshy areas, you can hear birds calling, frogs peeping and little scurrying sounds from the underbrush. The Nile River is full of life, from Egyptian vultures snatching ostrich eggs to golden jackals gnawing on a dead rabbit. Day and night in the Nile River delta, the hunt is on to find food - and to avoid becoming someone else’s next meal. All the living things are connected to one another in a food chain, from animal to animal, animal to plant, plant to insect, and insect to animal. What path will you take to follow the food chain through the river delta? Will you . . . Swoop through the air with an Egyptian slit-faced bat hunting insects? Stalk for frog dinner through thick reeds with a swamp cat? Scavenge for road kill with a striped hyena? Follow all three chains and many more on this who-eats-what adventure!




Food Webs at the Landscape Level


Book Description

Paying special attention to the fertile boundaries between terrestrial, freshwater, and marine ecosystems, this work shows not only what this new methodology means for ecology, conservation, and agriculture but also serves as a fitting tribute to Gary Polis and his major contributions to the field

Linking Species & Ecosystems


Book Description

I was asked to introduce this volume by examining "why a knowledge of ecosys tem functioning can contribute to understanding species activities, dynamics, and assemblages." I have found it surprisingly difficult to address this topic. On the one hand, the answer is very simple and general: because all species live in ecosystems, they are part of and dependent on ecosystem processes. It is impossible to understand the abundance and distribution of populations and the species diversity and composition of communities without a knowledge of their abiotic and biotic environments and of the fluxes of energy and mat ter through the ecosystems of which they are a part. But everyone knows this. It is what ecology is all about (e.g., Likens, 1992). It is why the discipline has retained its integrity and thrived, despite a sometimes distressing degree of bickering and chauvinism among its various subdisciplines: physiological, be havioral, population, community, and ecosystem ecology.
