Ecology

Ecology is a science concerned with the study of the relationships and interactions between organisms and their environments.

Ecology incorporates elements of biology, chemistry, geology, climatology, meteorology, and planetology.

Planetary Ecology is a study of the effects of climate, soil, water, geological processes, natural selection, and species population dynamics on the ecosystem of a natural or terraformed world.

Habitat Ecology is concerned with the way that organisms and ecosystems cope, adapt, survive or die out within the more "artificial" restrictions of a constructed biosphere, such as an O'Neill Orbital, Bishop Ring, Banks Orbital, Dyson Sphere, etc., and in its applications helps decide which species or group of species would best survive and flourish in such conditions.

Nanocology looks at ecosystems that form from wild self-replicating and self-evolving nano, or of artificial organisms with nanotech components.

Virchecology studies the ecological interactions of sims, alifes, and other virtuals in the context of their computronium and the underlying programming that determines their environment.

Autotroph - Text by M. Alan Kazlev
An organism that produces its own food from light or chemical energy and/or inorganic matter. Also called a Producer (or Primary Producer). Among terragen life forms, most green plants, many protists, and many prokaryotes are autotrophs. There are also alife and informational autotrophs/producers. Every food chain rests on autotrophs. Autotrophs in turn provide food for heterotrophs.

Institute in the Negentropy Alliance. Developed the classification scheme that formed the basis of the system of ecological classifications.
Biodegradable - Text by M. Alan Kazlev
A substance that can be broken down through the normal activity of microorganisms. Many Zoeific, Arcadian, and some Genen, polities have strict guidelines and regulations regarding this.
Biodiversity - Text by M. Alan Kazlev
The abundance of different biological species and varieties found in any environment, such as a natural biosphere, a ship, or an orbital or deep-space habitat. In almost every case (there are exceptions - e.g. on special purpose ships, military, freighter, etc etc), a high biodiversity is preferable to a low biodiversity for ecological robustness, resource value, evolutionary potential, and aesthetic appreciation.
Biomass - Text by M. Alan Kazlev
The total amount of living material (whether natural or artificial) in a particular area, estimated by adding up the weights of all of the organisms. Note that biomass is not the same as biodiversity; a monoculture has a high biomass but low biodiversity.
Biome - Text by Stephen Inniss and M. Alan Kazlev
A major ecosystem that extends over a broad region, has a characteristic climate, and presents a typical common appearance due to the suite of organisms that are adapted to it. In the context of a garden world or a large megahab it is a subset of the overall ecosphere. The classical biomes known to the humans of Old Earth have been widely replicated through the Terragen Sphere, but many more exotic biomes have also been discovered or resurrected or invented.
Bionanecology - Text by M. Alan Kazlev

Botworld - Text by Stephen Inniss
A large area that is dominated by, or consists entirely of, self-replicating and self-repairing forms which are of mechanical origin.
Canopy - Text by M. Alan Kazlev
The leaves and upper branches of rainforest trees, forming an upper "story", which in baseline Cenozoic terragen rainforests are usually around 20 to 40 meters up. This leafy environment is full of life in a tropical rainforest and includes insects, birds, reptiles, mammals, and other forms of life. Some eco-clades have adapted an entire culture, technology, and society to life in orbital canopy environments. There are also equivalent tweak, exotic chemistry, and virtual/alife "canopies" which serve the same ecological purpose, although they may differ markedly in structure and detail.

Consumer (ecology) - Text by M. Alan Kazlev
An organism (whether biological, alife, or other) that consumes other organisms to survive. Primary consumers feed on producers, secondary consumers feed on primary consumers, and so on. Depending on whether it is a biological, an alife, an ai, a neumann, or something else again, a consumer may feed on organic bodies (see also, heterotroph), information /data bodies (see also, infovore), energy bodies, and so on, The fact that there is an energy loss with each link of the food chain means that there are always more primary consumers than secondary consumers.
Coral Reef - Text by M. Alan Kazlev
Aquatic Terragen community of organisms, wave-resistant biological structure resulting from cementation processes and the skeletal construction of hermatypic corals, calcareous algae, and other calcium carbonate-secreting organisms. Forms a rich habitat for many types of marine organisms. Coral reefs are popular in many large Terragen habitats with a strong aquatic component and tropical or semi-tropical climate. Some coral reefs have been provolved to sapience.

A detritus feeder; an animal that ingests the decaying remains, feces, or cast off parts of other organisms. Examples from Old Earth include earthworms, many crabs, dung flies, sea cucumbers, woodlice, and so on. Analogous species are common wherever multicellular animal life has arisen. In some circumstances, such as at the bottom of earth's oceans or the bottom of To'ul'h Prime's atmosphere they are the predominant class of animal.

Ectotherm - Text by M. Alan Kazlev
Organisms - e.g. animals, neogens, etc - whose internal temperature changes with the environment. They rely upon behavior (e.g. lying in a sunny area) and sometimes bodily structures (heat-regulatory sails, etc) to control their body temperature.
Endotherm - Text by M. Alan Kazlev
Organism that generates its own body temperature to maintain a relatively constant internal temperature, which is usually higher than (but may in some xenoecologies be lower than) that of the surroundings. In terragen birds and mammals heat from the bloodstream circulates through the body in order to maintain the animal's temperature. Limners use a similar system but circulate paralymph rather than blood. To'u'ls use a cooling rather than a warming circulation, but again the principle is similar.
Environment - Text by M. Alan Kazlev
[1] The physical or virtual surroundings in which sentient beings live; The air, water, organisms, minerals, and other external objects that surround and affect an organism.
[2] From the perspective of any system, rest of the world or universe.
[3] Any precious biosphere, especially a garden world.
Extremophile - Text by M. Alan Kazlev
A rather chauvinistic term for any biological organism, whether terragen or xenobiont, natural or tweaked, that requires extreme (non-Earthlike) environments for growth or metabolism.
Food Chain - Text by M. Alan Kazlev
The energy exchange that constitutes the sum of interactions between predators and prey in which bionts, alifes, or other organisms obtain nutrition. The chain starts with plants or other autotrophs that are eaten by herbivores, which in turn are preyed upon by carnivores. These may in turn become food for other carnivores. When the organism dies, it becomes food for scavengers, detritivores, and decomposers.
Forest - Text by M. Alan Kazlev
Any biome type involving a dense concentration of trees or analogous neogens or xenophyta, distributed over a large area of land. In some biomes, such as rainforest, there are a number of distinct levels, such as canopy and forest floor, each with their distinct micro-ecologies.

Name given to the human-caused mass-extinction of a large proportion of baseline life and biodiversity on Old Earth; one of the six great extinction events on Earth (the others being the end Ordovician, Late Devonian, end Permian, end Triassic, and end Cretaceous). Only the end-Permian extinction is considered worse in estimated number of species and groups of organisms that died out.
Habitat (biology) - Text by M. Alan Kazlev
Any space (which includes food, water and shelter) suitable for the survival and reproduction of an organism.
Heterotroph - Text by M. Alan Kazlev
A heterotroph (or consumer) is an biological or alife that cannot make its own food and hence feeds on other organisms. Contrast autotroph.
Hylonanecology - Text by M. Alan Kazlev
A nanecology built solely on inorganic nanobots. The most extreme form is Machinonanecology. In practice however most hylonanecologies and bionanecologies tend to merge, with each using components found in the other; the difference between them being one of degree rather than of kind.
Industrial Ecology - Text by Chris Shaeffer
The study and implementation of efficient industrial systems coexisting with the natural environments within which they operate.
Interspecific Competition - Text by M. Alan Kazlev
Competition for food, territory, or other resources between two different species of organisms. Where competition is for exactly the same life-style and resource (the same ecological niche) the species that is most efficient will oust the less efficient species, driving it into extinction.
Intraspecific Competition - Text by M. Alan Kazlev
Competition for resources among members of the same a species; an important part of natural selection.
Limnology - Text by M. Alan Kazlev
Study of rivers, lakes, ponds and streams on a Gaian Type planet, the freshwater equivalent of Oceanography.

An organic ecology built solely on inorganic self-replicating devices working along traditionally machine-like principles.
Marine Biology - Text by M. Alan Kazlev
Branch of biology that deals with marine life (whether terragen or xenobiont), an important part of most biospheres. Areas of study include the ecology, physiology, life cycle, distribution, and migration of marine organisms, such as marine mammals, fish, invertebrates, algae, and plankton; classification of marine life; tagging, and tracking ocean organisms, microoceans and other orbital biomes; sea-farming; oceanography; introduction of aquatic life to artificial biospheres and newly terraformed worlds, megascale ocean ecology, designing marine ecosystems, and non-terragen marine organisms on other Gaian Type worlds.
Nano-ecology, Nanecology - Text by Anders Sandberg
A distributed system of nanodevices and the structures constructed by them that self-organizes in a bottom-up manner without any central control; analogous to an ecology. Sometimes used to denote the entire nanosphere of a world, even when parts of it are under top-down control.
Non-biodegradable - Text by M. Alan Kazlev
Materials that are not broken down by natural microorganisms in the environment; they require special bionano or hylonano or artificial organisms that use the same to be disassembled or recycled.

A biological organism or alife that lives off another organism (the host) without benefiting it. Hence Parasitism; relationship between two organisms in which one organism benefits at the other organism's expense.
Pelagic - Text by M. Alan Kazlev; amended by Stephen Inniss
Of, pertaining to, or living in the open ocean, on a planet, a moon or a sufficiently large large habitat, either at the surface or at intermediate depths. Some reserve the term specifically to open bodies of water a Gaian Type planet, but the broader usage is much more common.
Phytoplankton - Text by Stephen Inniss
Autotrophic planktonic organisms that are the primary producers within their ecology, usually via photosynthesis. Most often they are of microscopic size.
Plankton - Text by M. Alan Kazlev and Stephen Inniss
Organisms that live in in the water column or in a suitable atmosphere and drift or float in that environment, being incapable of swimming against the current or wind. Most garden worlds have planktonic organisms. Where larger or more actively moving organisms are present they depend on plankton for food. Analogues to biological plankton are found in some nanecologies and mechosystems.
