Ecology

Ecology (from Ancient Greek οἶκος (oîkos) 'house' and -λογία (-logía) 'study of') is the natural science of the relationships among living organisms and their environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere levels. 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 fields such as conservation biology, wetland management, natural resource management, and human ecology.

The term ecology (German: Ökologie) was coined in 1866 by the German scientist Ernst Haeckel. The science of ecology as it is known 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 such as 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.

Ecological art, or ecoart, is an art genre and artistic practice that seeks to preserve, remediate and/or vitalize the life forms, resources and ecology of Earth. Ecological art practitioners do this by applying the principles of ecosystems to living species and their habitats throughout the lithosphere, atmosphere, biosphere, and hydrosphere, including wilderness, rural, suburban and urban locations. Ecological art is a distinct genre from environmental art in that it involves functional ecological systems-restoration, as well as socially engaged, activist, community-based interventions. Ecological art also addresses politics, culture, economics, ethics and aesthetics as they impact the conditions of ecosystems. Ecological art practitioners include artists, scientists, philosophers and activists who often collaborate on restoration, remediation and public awareness projects. (Full article...)

Three polar bears approach the USS Honolulu (SSN-718), 280 miles from the North Pole. Polar bears have adapted through the process of evolution to have white fur that matches the white, icy arctic tundra.

North American beaver (Castor canadensis) dam in Tierra del Fuego

An invasive species is an introduced species that harms its new environment. Invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. Since the 20th century, invasive species have become serious economic, social, and environmental threats worldwide.

Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of invasion. For millennia, humans have served as both accidental and deliberate dispersal agents, beginning with their earliest migrations, accelerating in the Age of Discovery, and accelerating again with the spread of international trade.

Frances Crews James (born September 29, 1930) is an American ecologist who served as a Professor of Biological Sciences at Florida State University.

James studied geographic variation in the size and shape of birds, leading to transplant experiments with red-winged blackbirds and to tests of the theoretical assumptions underlying selection models. She is a member of the American Academy of Arts and Sciences. James, originally from Philadelphia, Pennsylvania, was immersed in the stream of biology at an early age being involved in the Academy of Natural Sciences Expeditions for Everyone. (Full article...)

An acre of windy prairie could produce between $4,000 and 10,000 worth of electricity per year—which is far more than the value of the land’s crop of corn or wheat.

The ISME Journal: Multidisciplinary Journal of Microbial Ecology is the official publication of the International Society for Microbial Ecology (ISME). The journal covers all areas of microbial ecology spanning the breadth of microbial life, including bacteria, archaea, microbial eukaryotes, and viruses. It publishes original research, review articles, and commentaries. (Full article...)

... in the United States, heating, ventilation and air conditioning (HVAC) systems account for 30% (4.65 EJ) of the energy used in commercial buildings and nearly 50% (10.1 EJ) of the energy used in residential buildings? Solar-powered heating, cooling and ventilation technologies can be used to offset a portion of this energy.
