Evolution and Ecology of the Organism

All life is chemical. That fact underpins the developing field of ecological stoichiometry, the study of the balance of chemical elements in ecological interactions. This long-awaited book brings this field into its own as a unifying force in ecology and evolution. Synthesizing a wide range of knowledge, Robert Sterner and Jim Elser show how an understanding of the biochemical deployment of elements in organisms from microbes to metazoa provides the key to making sense of both aquatic and terrestrial ecosystems. After summarizing the chemistry of elements and their relative abundance in Earth's environment, the authors proceed along a line of increasing complexity and scale from molecules to cells, individuals, populations, communities, and ecosystems. The book examines fundamental chemical constraints on ecological phenomena such as competition, herbivory, symbiosis, energy flow in food webs, and organic matter sequestration. In accessible prose and with clear mathematical models, the authors show how ecological stoichiometry can illuminate diverse fields of study, from metabolism to global change. Set to be a classic in the field, "Ecological Stoichiometry" is an indispensable resource for researchers, instructors, and students of ecology, evolution, physiology, and biogeochemistry. "From the foreword by Peter Vitousek: ""[T]his book represents a significant milestone in the history of ecology. . . . Love it or argue with it--and I do both--most ecologists will be influenced by the framework developed in this book. . . . There are points to question here, and many more to test . . . and if we are both lucky and good, this questioning and testing will advance our field beyond thelevel achieved in this book. I can't wait to get on with it.

Evolution And Ecology Of The Organism

Digital organism - A digital organism is a self-replicating computer program that mutates and evolves. Digital organisms are used as a tool to study the dynamics of Darwinian evolution, and to test or verify specific hypotheses or mathematical models of evolution.

Center for Social Evolution and Symbiosis - The Centre for Social Evolution and Symbiosis studies the ecology, evolution, and population genetics of complex insect societies, using ants and termites as its major empirical model systems.

Model organism - A model organism is a species that is extensively studied to understand particular biological phenomena, with the expectation that discoveries made in the model organism will provide insight into the workings of other organisms. This is possible because fundamental biological principles such as metabolic, regulatory, and developmental pathways, and the genes that code for them, are conserved through evolution.

Sex, Ecology, Spirituality - Sex, Ecology, Spirituality: The Spirit of Evolution is integral philosopher Ken Wilber's magnum opus. Wilber intends it to be the first volume of a series called The Kosmos Trilogy, but subsequent volumes are still in preparation.

Environmental Impact of Genetically Modified Organism - Environmental Impact of Genetically Modified Organism Genetically modified organism - A genetically modified organism, or GMO is an organism whose genetic material has been altered using techniques in genetics generally known as "recombinant DNA technology". Recombinant DNA technology is the ability to combine DNA molecules from different sources into the one molecule in a test tube. Genetically modified food - A genetically modified food is a food product derived in whole or part from a genetically modified organism (GMO) such as a crop ...

Several chapters closely integrate ecology with genetics approach ecology evolution molecular and evolutionary biology, approach ecology evolution molecular and others illustrate how metapopulation concepts approach ecology evolution molecular and models can be applied to answer questions about conservation, epidemiology, approach ecology evolution molecular and speciation. ...

Organic Plant Nutrients - Organic Plant Nutrients Saprotroph - A Saprotroph (or saprobe) is an organism that obtains its nutrients from non-living organic matter, usually dead and decaying plant or animal matter, by absorbing soluble organic compounds. Since saprotrophs cannot make food for themselves, they are considered a type of heterotroph. Phloem - In vascular plants, phloem is the living tissue that carries organic nutrients, particularly sucrose to all parts of the plant where needed. In trees, the phloem is part of the bark, hence the ...

Science Agriculture Organization - Science Agriculture Organization Food and Agriculture Organization - With its headquarters in Rome, the Food and Agriculture Organization (FAO) is a specialized agency of the United Nations that works to raise levels of nutrition and standards of living; to improve the production, processing, marketing, and distribution of food and agricultural products; to promote rural development; and, by these means, to eliminate hunger. In the past, the United States and several other european nations have contributed to this organization by providing blankets, food, ...

Algal ecologists and taxonomists play an important role in the understanding of aquatic ecosystems: their biodiversity, productivity, interactions with other organisms, and water quality assessment, biological composition, ecology, evolution, or molecular biology. They use the word "society" to refer to a group with more or less clear boundaries that reproduces itself over time human societies change towards some optimal form of organization. On this account, highly evolved societies are those which provide maximum freedom and benefit to their members. Others have argued that biological and social evolution.
