The most important things in life are not things.

conjunctive symbiosis (s) (noun), conjunctive symbioses (pl)
1. A symbiosis (relation between two different species of organisms that are interdependent and each gains benefits from the other) characterized by the bodily union between the symbionts or one of two different organisms that live together.
2. Ordinarily symbiosis where the association is advantageous, or often necessary, to one or both, and not harmful to either.
3. When there is a bodily union in extreme cases so close that the two form practically a single body, as in the union of algae and fungi to form lichens, and in the inclusion of algae in radiolarians (any of various marine protozoans of the group Radiolaria, having rigid skeletons usually made of silica).
Any animal (coprozoite) or plant (coprophyte) living or feeding on dung.
A specialist in the effects of low temperatures on biological systems.
1. The study of the effects of low temperatures on living organisms or biological systems; especially, warm-blooded animals.
2. The study of life and its constituents below its normal living temperature, including cryogenic temperatures (below -80 degrees Centigrade).
In physiology, the carrying on of bodily functions at low temperatures.
Organisms that are typically hidden or concealed in crevices or under stones.
1. The condition in which all external signs of metabolic activity are absent from a dormant organism.
2. Latent life; the state of an organism showing no visible signs of life.
3. The condition of an organism that must in theory have at one time existed, but that has left no fossil traces.
4. A state in which the signs of life of an organism have weakened to the point where they are barely measurable or no longer measurable.
A reference to organisms that are typically hidden or concealed in crevices or under stones.
The influence of one cell on another.

A form of energy, totally unrelated to electricity, light, heat, or sound, which is generated by living tissues; the vital principle in all living tissues. The term was first introduced in 1923 by Frederic Wood Jones, who defined it as "the influence of body cells on other body cells"; the “call of cell to cell”.

dark biology
Scientific research related to biological weapons.

The phrase "dark biology" was coined by the science writer and novelist Richard Preston in his self-described "trilogy on dark biology": The Hot Zone (1994), The Cobra Event (1997), and The Demon In the Freezer (2002).

1. The existence of distinct genetically determined forms of the same species; such as, distinct male and female forms or distinct young and mature forms.
2. Characterized by a regular alternation of parasitic and nonparasitic phases, as in the life cycle of gordian (long slender worms found in water whose larva live as parasites on arthropods) or horsehair worms (nematode worms that live as parasites in the digestive tracts of domestic animals).
The study of the relationships of organisms to their natural environments.
The conditions pertaining to a mode of life within a specific habitat.
