Magnetotellurics (MT) is an electromagnetic geophysical method for inferring the earth's subsurface electrical conductivity from measurements of natural geomagnetic and geoelectric field variation at the Earth's surface.
An Alpine chough in flight at 3,900 m (12,800 ft). Organisms can live at high altitude, either on land, in water, or while flying.Decreased oxygen availability and decreased temperature make life at such altitudes challenging, though many species have been successfully adapted via considerable physiological changes.

A microclimate (or micro-climate) is a local set of atmospheric conditions that differ from those in the surrounding areas, often slightly but sometimes substantially. The term may refer to areas as small as a few square meters or smaller (for example a garden bed , underneath a rock, or a cave) or as large as many square kilometers.
The Montana Department of Environmental Quality is a state-level government agency in Montana. The agency was founded by the Montana Legislature in 1995 as the Montana Board of Environmental Review. [1] It is responsible for monitoring air, water, energy, and mining standards, in addition to regulatory services. [2] [3] [4]
