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 simple six-carbon sugar produced by photosynthesis. An energy source for both plants and animals; it breaks down from ingested carbohydrates. Cellulose and chitin contain it.

The mass delusion, supplemented by expensive advertising, that using up as many products as possible as quickly as possible will somehow not cave in the biosphere. See Dieback.
Industry:Biology
Most Americans do not realize that eating processed food almost always means eating something genetically altered, in part because the foods are not normally labelled as such.
Industry:Biology
A form of nucleic acid organized into pairs of double-helix molecules packaged into chromosomes carrying the genetic code. The molecules are made of linked nucleotides units with a sugar, a phosphate, and one of four base chemicals adenine, thymine, guanine, and cytosine. These bases join like ladder rungs--always an A to a T and a C to a G--with the sugar-phosphate forming the outside "backbone" of the strand. The sequence of these nucleotides, with each group of three spelling one anino acid "codon," determines the kind of protein manufactured when translated by strands of RNA. (James Watson and Francis Crick discovered this structure in 1953.) RNA also aids in DNA's replication. Everything living carries the same gene code, one reason scientists are so confident we are all related biologically. Some DNA sequences are identical in humans and bacteria, a fact that underlines our common biological origins.

Industry:Biology
Using natural means like predators to control pests, like growing ginger to repel snails and slugs and nasturtiums to ward off aphids, which are also food for ladybugs and lacewing moths. Goldfish placed in water storage containers eat incoming mosquitos.
Industry:Biology
Created by C. Hart Merriam in 1894 to classify environments by temperature and rainfall. There are eight major life zones: Arctic-Alpine, Boreal (Hudsonian), Boreal (Canadian), Transition, Carolinian, Loouisianian, Upper Sonoran, and Lower Sonoran.
Industry:Biology
Marshy land covered by shrugs and mosses. Their acidic soils accumulate peat, the thick, carbonized vegetable tissue decomposed in water. The words "bogeyman" and "heathen" derive from outcasts who inhabited these poorly drained areas.
Industry:Biology
Decomposition of organic matter into its inorganic (mineral) components (e. G. , petrified wood). In archeology, the replacement of fossil bone with water-borne minerals.
Industry:Biology
A wave that collapses forward near the shoreline as the shoaling sea bottom makes it top-heavy. It collapses when the ratio of its height to its wavelength passes 1:7.
