Terrapsychology is a word coined by Craig Chalquist to describe deep, systematic, trans-empirical approaches to encountering the presence, soul, or "voice" of places and things: what the ancients knew as their resident genius loci or indwelling spirit. This perspective emerged from sustained ...
A substance (usually toxic) entering an environment from a point source (a confirmable location). Example: wastewater from a manufacturing plant (effluence from affluence).
Industry:Biology
Any planting approach that leaves 30% or more of the soil covered by plant residue or cover crop while tilling as little as possible to avoid destroying the soil structure.
Industry:Biology
An evergreen shrub community adapted to dry seasons. Although it secrets a resin that burns like gasoline, homes continue to be built in its potentially explosive thickets.
Industry:Biology
In theory, a body that absorbs and emits 100% of the electromagnetic radiation that strikes it and therefore appears black. Graphite comes close, with all but 3% absorption.
Industry:Biology
The removal of a layer of soil by rain or runoff. Topsoil accumulated for centuries or eons can erode away in minutes unless anchored with vegetation and properly drained.
Industry:Biology
The difference in angle between true north and magnetic north, or true south and magnetic south. The poles occasionally switch, also, which last happened 780,000 years ago.
Industry:Biology
A common (more than 7,000 species) algae, especially in estuaries, with nucleated cells and chloroplasts that make food from sunlight. The "higher" plants evolved from it.
Industry:Biology
Howard Odum's hypothesis that ecosystems change not only gradually, but in the unpredictable starts, fits, and "pulses" characteristic of systems subject to chaos dynamics.
Industry:Biology
When heat from the ground rises, cools, saturates the air, and falls, most often as rain from a highly localized storm. Common along the equator and deep inside continents.
Industry:Biology
Water pushed upward by the hydrostatic pressure of a confined aquifer. Overuse of artesian wells lowers the water table and sometimes makes nearby land sink (subsidence).
