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 ...

Industry:Biology
The path of food energy transfer from green plants (primary producers) to grazers (primary consumers), omnivors and carnivores (secondary consumers), and to their predators (top carnivores). The detritus food chain starts when organic matter settles on the ground and breaks down. Because such linear food chains are relatively rare in nature, see Food Web.
Industry:Biology
A relatively undisturbed forest containing many old trees and luxuriant levels of vegetation from the forest floor to its canopy. Logging old growth forests triggers ecological consequences, some known (loss of water, rainfall, habitat, oxygen, carbon, etc. ) and some unknown.
Industry:Biology
The rising of the Earth's average global temperature because of greenhouse gases accumulating in the atmosphere. The scientific emphasis has swung from whether global warming exists to how to minimize the damage it will cause. One example of many: according to the British Antarctic Survey and U. S. Geological Survey as of 5005, 87% of 244 glaciers studied have retreated over the last fifty years, and average retreat rates are accelerating. If the Greenland ice sheet melts, sea levels worldwide will rise twenty feet. See Greenhouse Effect.
Industry:Biology
A nerve cell that transmits electrochemical impulses. Neurons were thought to work somewhat like electric switches: when triggered at the dendrite end by an incoming nerve pulse, they generate a pulse down the axon (with help from the Nodes of Ranvier, which work like signal boosters) to the terminal button, where the pulse triggers the release of neurotransmitter chemicals into the synpase, the space between one neuron and another. These chemicals then trigger a pulse (or inhibit one) in other neurons. As it turns out, however, each neuron is more like a microchip than a simple switch. At any moment only abut 5-10% of the human brain's neurons are sparking, but eventually they all do, a fact that contradicts the common but inaccurate idea that people use only a small portion of their brains. (How much of the brain a person uses at once, or regularly, is another matter. ) The adult brain contains about 10 billion neurons, with the brain as a whole drawing 20-40 watts of power, and with an ultimate storage capacity of (very roughly) 100 terrabytes: about the same as every book ever written, digitized. It's hard to estimate because each dendrite contacts about 10,000 other neurons in extraordinarily complicated neural nets.
Industry:Biology
The movements of continental plates over the mantle whose currents pull them around the Earth's surface. As far back as 1912, Alfred Wegener noted that the continents fit together like puzzle pieces into some lost whole (see Pangaea, a name he coined). He was ignored, but in 1929, Arthur Holmes decided that thermal convection currents in the mantle could move continents around. These ideas also account for where the seafloor comes from (molten material emitted through cracks between plates), how some of it disappears (when the edge of one plate vanishes under another--subduction), and why volcanic and mountain-building activity so often surfaces in belts (plate edges).
