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 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. (Full article...) Selected article - The issue of what exactly defines a vacant niche, also known as empty niche, and whether they exist in ecosystems is controversial. The subject is intimately tied into a much broader debate on whether ecosystems can reach equilibrium, where they could theoretically become maximally saturated with species. Given that saturation is a measure of the number of species per resource axis per ecosystem, the question becomes: is it useful to define unused resource clusters as niche 'vacancies'?

Clear boundaries make lakes convenient to study using an ecosystem approach.

(from Ecosystem) The leaves of an Alnus nepalensis tree provide a microhabitat for species like the leaf beetle Aulacophora indica. (from Habitat) Wetland habitat types in Borneo (from Habitat) Few creatures make the ice shelves of Antarctica their habitat, but water beneath the ice can provide habitat for multiple species. Animals such as penguins have adapted to live in very cold conditions. (from Habitat) Global oceanic and terrestrial phototroph abundance, from September 1997 to August 2000. As an estimate of autotroph biomass, it is only a rough indicator of primary production potential and not an actual estimate of it.

This is the Gambia River in Senegal's Niokolo-Koba National Park. (from Ecosystem) A simple trophic cascade diagram.

The fish community of this lake has remained stable over a long period until a number of introductions in the 1970s restructured its food web.

Tiger as flagship species for a campaign in Tamil Nadu, India In conservation biology, a flagship species is a species chosen to raise support for biodiversity conservation in a given place or social context. Definitions have varied, but they have tended to focus on the strategic goals and the socio-economic nature of the concept, to support the marketing of a conservation effort. The species need to be popular, to work as symbols or icons, and to stimulate people to provide money or support. Species selected since the idea was developed in 1980s include widely recognised and charismatic species like the black rhinoceros, the Bengal tiger, and the Asian elephant. Some species such as the Chesapeake blue crab and the Pemba flying fox, the former of which is locally significant to Northern America, have suited a cultural and social context. (Full article...)

Selected quote - “ A land ethic for tomorrow should be as honest as Thoreau's Walden, and as comprehensive as the sensitive science of ecology. It should stress the oneness of our resources and the live-and-help-live logic of the great chain of life. ” — Stewart Udall Ecology news From the Wikinews Environment portal April 23: European Union to reduce carbon emissions by 55% of 1990 levels by 2030 November 27: Wikinews interviews Craig Farquharson, Liberal Democrat candidate for 2020 Groom by-election November 27: Wikinews interviews Sandra Jephcott, Sustainable Australia candidate for 2020 Groom by-election December 14: Greta Thunberg named 2019 Time Person of the Year November 23: Researchers break down deaths due to power plant pollution in the United States November 21: Slippery business: Materials scientists invent new coating for self-cleaning, water-efficient toilets October 19: Northern Arapaho Tribe welcomes buffalo herd in Wyoming, United States October 12: Scientists describe how 'upside-down rivers' of warm water break Antarctica's ice shelf October 5: Voracious fish defend coral reefs against warming, say scientists September 8: Scientists report skyrocketing phytoplankton population in aftermath of Kīlauea eruption Additional News Highlights November 5, 2009: "New ocean forming in African desert."
