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 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 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.

Intertidal ecology is the study of intertidal ecosystems, where organisms live between the low and high tide lines. At low tide, the intertidal is exposed whereas at high tide, the intertidal is underwater. Intertidal ecologists therefore study the interactions between intertidal organisms and their environment, as well as between different species of intertidal organisms within a particular intertidal community. The most important environmental and species interactions may vary based on the type of intertidal community being studied, the broadest of classifications being based on substrates—rocky shore and soft bottom communities. Organisms living in this zone have a highly variable and often hostile environment, and have evolved various adaptations to cope with and even exploit these conditions. One easily visible feature of intertidal communities is vertical zonation, where the community is divided into distinct vertical bands of specific species going up the shore. Species ability to cope with abiotic factors associated with emersion stress, such as desiccation determines their upper limits, while biotic interactions e.g.competition with other species sets their lower limits.

Loch Lomond in Scotland forms a relatively isolated ecosystem.

Pines in the preserve The Albany Pine Bush, referred to locally as the Pine Bush, is one of the largest inland pine barrens in the world. It is centrally located in New York's Capital District within Albany and Schenectady counties, between the cities of Albany and Schenectady. The Albany Pine Bush was formed thousands of years ago, following the drainage of Glacial Lake Albany. The Albany Pine Bush is the sole remaining undeveloped portion of a pine barrens that once covered over 40 square miles (100 km2),  and is "one of the best and last remaining examples of an inland pine barrens ecosystem on Earth." By 2008 it included all parcels of the Albany Pine Bush Preserve (a state nature preserve spanning 3,200 acres (1,300 ha)), the properties that connect these protected parcels, and some of the surrounding areas that abut the preserve. The 135-acre (55 ha) Woodlawn Preserve and surrounding areas in Schenectady County are the western sections of the Pine Bush, separated geographically by other properties from the Albany Pine Bush Preserve in Albany County.

Evelyn Hutchinson at Yale University. He was a creative pioneer in several areas, including quantitative palynology, cycling of natural isotopes, biogeochemistry, population dynamics, systematics and ecology of freshwater zooplankton, and he promoted the use of life tables in ecology. In 1938, Deevey received his Ph.D. in Zoology from Yale University as a student of Hutchinson. He taught at Yale from 1946 to 1968. In 1971, he became curator of paleoecology at the Florida Museum of Natural History and a research professor at the University of Florida, where he remained until the time of his death.
