Ecology

Ecology (from Ancient Greek οἶκος (oîkos) 'house', and -λογία (-logía) 'study of') is the natural science of the relationships among living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps with the closely related sciences of biogeography, evolutionary biology, genetics, ethology, and natural history.

Ecology is a b

branch of biology, and is the study of abundance, biomass, and distribution of organisms in the context of the environment. It encompasses life processes, interactions, and adaptations; movement of materials and energy through living communities; successional development of ecosystems; cooperation, competition, and predation within and between species; and patterns of biodiversity and its effect on ecosystem processes.

Ecology has practical applications in conservation biology, wetland management, natural resource management (agroecology, agriculture, forestry, agroforestry, fisheries, mining, tourism), urban planning (urban ecology), community health, economics, basic and applied science, and human social interaction (human ecology).

The word ecology (German: Ökologie) was coined in 1866 by the German scientist Ernst Haeckel. The science of ecology as we know it today began with a group of American botanists in the 1890s. Evolutionary concepts relating to adaptation and natural selection are cornerstones of modern ecological theory.

Ecosystems are dynamically interacting systems of organisms, the communities they make up, and the non-living (abiotic) components of their environment. Ecosystem processes, such as primary production, nutrient cycling, and niche construction, regulate the flux of energy and matter through an environment. Ecosystems have biophysical feedback mechanisms that moderate processes acting on living (biotic) and abiotic components of the planet. Ecosystems sustain life-supporting functions and provide ecosystem services like biomass production (food, fuel, fiber, and medicine), the regulation of climate, global biogeochemical cycles, water filtration, soil formation, erosion control, flood protection, and many other natural features of scientific, historical, economic, or intrinsic value.

The natural environment or natural world encompasses all living and non-living things occurring naturally, meaning in this case not artificial. The term is most often applied to Earth or some parts of Earth. This environment encompasses the interaction of all living species, climate, weather and natural resources that affect human survival and economic activity. The concept of the natural environment can be distinguished as components:

In contrast to the natural environment is the built environment. Built environments are where humans have fundamentally transformed landscapes such as urban settings and agricultural land conversion, the natural environment is greatly changed into a simplified human environment. Even acts which seem less extreme, such as building a mud hut or a photovoltaic system in the desert, the modified environment becomes an artificial one. Though many animals build things to provide a better environment for themselves, they are not human, hence beaver dams, and the works of mound-building termites, are thought of as natural.

This coral reef in the Phoenix Islands Protected Area provides habitat for numerous marine species.

In ecology, habitat refers to the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate.

The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior of a stem, a rotten log, a rock or a clump of moss; a parasitic organism has as its habitat the body of its host, part of the host's body (such as the digestive tract), or a single cell within the host's body.

Ramon Margalef
Ramon Margalef López (Barcelona 16 May 1919 - 23 May 2004) was a Spanish biologist and ecologist. He was Emeritus Professor of Ecology at the Faculty of Biology of the University of Barcelona. Margalef, one of the most prominent scientists that Spain has produced, worked at the Institute of Applied Biology (1946–1951), and at the Fisheries Research Institute, which he directed during 1966–1967. He created the Department of Ecology of the University of Barcelona, from where he trained a huge number of ecologists, limnologists and oceanographers. In 1967 he became Spain's first professor of ecology. (Full article...)

I used to think of the environment as trees and blue sky. Then I learned that for some people, the environment is gangs and concrete. All the issues that we face are connected. Worldwide, ecosystems are being destroyed, and indigenous peoples are losing their homelands and their entire way of life. Three out of every five African-Americans and Latinos in the US lives in a community with a toxic waste site. As long as pollution is being produced, it's going to go somewhere, and as long as there are marginalized communities where land is cheaper and the people don't have the time or the money to fight back, polluters will have a place to deposit toxins. As long as people and the planet are being exploited, and billions of dollars are being made precisely because laborers and the environment are being abused and used up, there will be children going hungry and ecological destruction. As long as war and violence are in our hearts and our streets as well as in our nations, as long as corporate greed and unsustainable consumption are at the forefront of our economies, no child will be born into a truly safe, peaceful or loving world.

... paleoecology uses data from fossils and subfossils to reconstruct the ecosystems of the past? It involves the study of fossil organisms and their associated remains, including their life cycle, living interactions, natural environment, and manner of death and burial to reconstruct the paleoevironment.
