The species chromatogram, a new graphical method to represent, characterize, and compare the ecological niches of different species
Abstract The ecological niche sensu Hutchinson is defined as the set of environmental conditions allowing a species to grow, maintain, and reproduce. This conception of the niche, which is assimilated to a p ‐dimensional hypervolume, with p representing all environmental variables, has been widely a...

Abstract The ecological niche sensu Hutchinson is defined as the set of environmental conditions allowing a species to grow, maintain, and reproduce. This conception of the niche, which is assimilated to a p ‐dimensional hypervolume, with p representing all environmental variables, has been widely applied in ecology.
