Ecological niche - Reflexions

Ecological niche

G.E. Hutchinson (1957) defined an ecological niche as a hypervolume (an envelope) where each dimension of space represents a resource (food, materials, spatial, hidden supply, substrates or perches, …) or a condition (temperature, precipitation, acidity, …) of the environment. The quantity of resources varies in space and time according to the activity of the species. The conditions and resources are limiting conditions that can be organized into a hierarchy in order to study the vulnerability of the species in the environment.
