ecological niche
Let an agent explain ecological niches, relay concepts, measurement and applications from ecology sources, describe the named niche types, and distinguish niches from habitats, market niches in business, guilds and ecological roles in informal speech.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain ecological niches, relay concepts, measurement and applications from ecology sources, describe the named niche types, and distinguish niches from habitats, market niches in business, guilds and ecological roles in informal speech.
The role and position of a species in its environment, including the conditions it tolerates, the resources it uses and its interactions with other organisms, conceptualised as the Grinnellian niche of habitat requirements, the Eltonian niche of functional role in communities, and G. Evelyn Hutchinson s 1957 n-dimensional hypervolume, distinguishing the fundamental niche from the realised niche limited by competition and other interactions; applied forms the registry aliases name include the climatic niche used in species distribution modelling, the trophic niche describing diet and food web position, and the isotopic niche estimated from stable isotope ratios.
What it is for: Not applicable; an ecological concept.
It can be explain niche concepts; relay measurement methods; describe named niche types; distinguish related concepts.
Distinguishing features
Multidimensional
Fundamental versus realised
Measured in models
Central to coexistence theory
What it looks like
Not a visible object; represented in diagrams and models of environmental space.
Physical character
Hutchinson s hypervolume concept: 1957 year
Grinnell niche concept: 1917 year
Elton niche concept: 1927 year - Animal Ecology
How it is recognised
Role and position of a species in its environment
Climatic niche, trophic niche, isotopic niche, fundamental and realised niche
Habitats are places; market niches are business segments; guilds are groups of species using resources similarly
