Study
Concluding remarks
Hutchinson, G. E.
Cold Spring Harbor Symposia on Quantitative Biology, 1957
Formalises the niche as a region in a space whose axes are environmental variables and resources — temperature, humidity, prey size and so on — within which a population can persist. Distinguishes the region a species could occupy in the absence of competitors from the smaller region it actually occupies.
- Sample size
- theoretical formulation
The niche can be treated as a multidimensional volume rather than a place, which makes it possible to ask precise questions about overlap, breadth and limiting similarity.
What it means
The authors' reading, and ours. Where they differ, that difference is the point.
How the authors put it
A niche is a property of a species in relation to its environment, not a location or a role that exists independently of the organism.
How NatureHQ reads it
The record behind the site’s refusal of "a niche is an animal’s job". A job exists whether or not anybody does it; a niche described this way does not — it is defined by the conditions under which a particular population can persist. That distinction is what makes the fundamental and realised versions coherent, and it is what a teaching shortcut throws away.
- A conceptual formulation, not a measurement, and the axes of a real niche are never fully enumerable.
- The framework is easier to state than to apply: measuring a niche volume for any actual species is extremely difficult.
What this study is used for on NatureHQ
One study can inform several subjects. Here is everywhere this one is cited.
Ecological niche
Where a species lives has boundaries of two kinds: what it can physically stand, and what another organism will let it have. You cannot tell them apart by looking — you have to remove the neighbour.
Ecological niche
A niche is not an animal’s job and not the place it lives. It is the set of conditions and resources under which its population can persist — which means a niche does not sit waiting to be filled.
