Abstract

The use of Horn's index is extended to express niche separation in multidimensional niche spaces where each axis represents a combination of states of environmental variables of the nominal or ordinal type. Pairwise niche separation coefficients are applied to snail assemblages in three different successional seres of terrestrial plant communities in the Hungarian Great Plain. Matrices of separation coefficients are subjected to metric and nonmetric multidimensional scaling in order to reveal underlying niche relationships in the assemblages. Principal coordinates analysis proved to be more effective in detecting species groups than nonmetric scaling.
