Food Webs: From Connectivity to Energetics by Anonim Pdf

The most recent volume of this series, Advances in Ecological Research, demonstrates a captivating knowledge of recent advances in the analysis of food webs. A food web describes the network of predator-prey interactions within a community. The simplest description of a food web specifies only who eats whom (a connectance web), with no indication of how much or how often. Chapters in this book begin with a discussion of the most detailed connectance webs ever compiled, and advance to incorporate information on the body size and numerical abundance of the species. The results yield new ways of describing food webs and powerful new models for estimating patterns of energy flow in ecosystems. Provides fresh ways of describing food webs and applies previous observations in a new context Ranked as the #1 publication in the Institute for Scientific Information in the Ecology section of 2000 Powerful new theory AND application to some of the best food web data in the world Many mathematical models for food web structure and function Integrates previously unconnected perspectives on the description of ecological communities

Energetic Food Webs by John C. Moore,Peter C. de Ruiter Pdf

This novel book bridges the gap between the energetic and species approaches to studying food webs, addressing many important topics in ecology. Species, matter, and energy are common features of all ecological systems. Through the lens of complex adaptive systems thinking, the authors explore how the inextricable relationship between species, matter, and energy can explain how systems are structured and how they persist in real and model systems. Food webs are viewed as open and dynamic systems. The central theme of the book is that the basis of ecosystem persistence and stability rests on the interplay between the rates of input of energy into the system from living and dead sources, and the patterns in utilization of energy that result from the trophic interactions among species within the system. To develop this theme, the authors integrate the latest work on community dynamics, ecosystem energetics, and stability. In so doing, they present a unified ecology that dispels the categorization of the field into the separate subdisciplines of population, community, and ecosystem ecology. Energetic Food Webs is suitable for both graduate level students and professional researchers in the general field of ecology. It will be of particular relevance and use to those working in the specific areas of food webs, species dynamics, material and energy cycling, as well as community and ecosystem ecology.

Body Size: The Structure and Function of Aquatic Ecosystems by Alan G. Hildrew,David G. Raffaelli,Ronni Edmonds-Brown Pdf

Ecologists have long struggled to predict features of ecological systems, such as the numbers and diversity of organisms. The wide range of body sizes in ecological communities, from tiny microbes to large animals and plants, is emerging as the key to prediction. Based on the relationship between body size and features such as biological rates, the physics of water and the amount of habitat available, we may be able to understand patterns of abundance and diversity, biogeography, interactions in food webs and the impact of fishing, adding up to a potential 'periodic table' for ecology. Remarkable progress on the unravelling, describing and modelling of aquatic food webs, revealing the fundamental role of body size, makes a book emphasising marine and freshwater ecosystems particularly apt. In this 2007 book, the importance of body size is examined at a range of scales that will be of interest to professional ecologists, from students to senior researchers.

Metabolic Ecology by Richard M. Sibly,James H. Brown,Astrid Kodric-Brown Pdf

Metabolic Ecology Most of ecology is about metabolism, the ways that organisms use energy and materials. The energy requirements of individuals (their metabolic rates) vary predictably with their body size and temperature. Ecological interactions are exchanges of energy and materials between organisms and their environments. Therefore, metabolic rate affects ecological processes at all levels: individuals, populations, communities and ecosystems. Each chapter focuses on a different process, level of organization, or kind of organism. It lays a conceptual foundation and presents empirical examples. Together, the chapters provide an integrated framework that holds the promise for a unified theory of ecology. The book is intended to be accessible to upper-level undergraduates and graduate students, but also of interest to senior scientists. Its easy-to-read chapters and clear illustrations can be used in lecture and seminar courses. This is an authoritative treatment that will inspire future generations to study metabolic ecology.

How Species Interact by Roger Arditi,Lev R. Ginzburg Pdf

Understanding the functioning of ecosystems requires the understanding of the interactions between consumer species and their resources. How do these interactions affect the variations of population abundances? How do population abundances determine the impact of predators on their prey? The view defended in this book is that the "null model" that most ecologists tend to use is inappropriate because it assumes that the amount of prey consumed by each predator is insensitive to the number of conspecifics. The authors argue that the amount of prey available per predator, rather than the absolute abundance of prey, is the basic determinant of the dynamics of predation. This so-called ratio dependence is shown to be a much more reasonable "null model."

Ecological Networks by Mercedes Pascual,Jennifer A. Dunne Pdf

Food webs are one of the most useful, and challenging, objects of study in ecology. These networks of predator-prey interactions, conjured in Darwin's image of a "tangled bank," provide a paradigmatic example of complex adaptive systems. This book is based on a February 2004 Santa Fe Institute workshop. Its authors treat the ecology of predator-prey interactions, food web theory, structure and dynamics. The book explores the boundaries of what is known of the relationship between structure and dynamics in ecological networks and will define directions for future developments in this field.

From Energetics to Ecosystems: The Dynamics and Structure of Ecological Systems by N. Rooney,K.S. McCann,D.L.G. Noakes Pdf

Ecosystems are complex and enigmatic entities that are ultimately our life support systems. This book explores developments that unfold when math and physics meet ecology. Leading ecologists examine ecosystems from theoretical, experimental, and empirical viewpoints. The book begins by simplifying and synthesizing nature’s complex relationships. It then moves on to explore the mapping between food web structure and function and ends with the role of theory in integrating different research areas.
